Healthy sleep plays a vital role in the body’s overall health, as it ensures muscle growth, recovery, and illness prevention. This is especially true for home D.I. Yers’ fitness enthusiasts, weekend warriors, athletes, and physically active individuals. When sleeping, the body goes into recovery mode, releasing hormones and other chemicals to repair and restore muscle. A healthy night’s sleep provides the rest the mind and body need to perform at optimal levels.

Healthy Sleep
Sleep is vital for recovering from workouts. This could be construction work, exercise, gardening, sports, landscaping, any activity that uses bodyweight or works against some form of resistance. The muscles cannot repair themselves properly without proper sleep. Sleep aids the muscles in releasing protein-building amino acids, helping them grow in size and strength.
Growth hormone is released during non-REM sleep that stimulates tissue growth and repairs muscle.
During REM or rapid eye movement sleep, blood pressure drops, breathing slows and deepens, the brain relaxes, and blood supply to the muscles increases, feeding them oxygen and nutrients.
Unhealthy Sleep
Sleep maintains the muscles’ sharpness, coordination, function, and muscle movement patterns that improve physical performance. The body needs to sleep for at least 7 hours a night for muscles to grow properly. Not getting healthy sleep decreases protein synthesis activity and increases the activity of degradation that leads to muscle loss.
Less Sleep Leads To Eating More
Hormonal changes occur when the body sleeps less, causing individuals to feel hungry more often, increasing the amount of food taken in because after eating, the body does not feel full right away, so the individual continues to eat. Without sleep, the body decreases the production of a hormone that indicates when the body is full and activates a hormone that causes hunger. Insufficient sleep also lowers the body’s sensitivity to insulin. Because of this, the muscle fuel glycogen is not adequately replenished. Without the regular restoration of glycogen, individuals have less energy, insulin sensitivity decreases, increasing the risk of diabetes.
Physical Health
Unhealthy sleep also impacts overall physical health. Individuals that do not get healthy sleep have an increased risk of developing:
Sugar raises blood sugar, which triggers the pancreas to release insulin, fueling the cells causing overstimulation.
Eliminating sugar after dinner can help the body fall asleep.

Automobile accidents and crashes can cause all kinds of damage to the body even when the accident/crash is not severe. Physical symptoms might not present at all for several days, even weeks. This is known as having delayed injury symptoms. These can include:
Swelling.
Stiffness.
Aching.
Pain that radiates all over the body.
Sleep problems.
Headaches.
Brain fog.
Disorientation.
Memory problems.
Chiropractic and physical therapy rehabilitation can restore the body’s alignment, stop inflammation, loosen, stretch and strengthen the musculoskeletal system restoring optimal health.

Adrenaline
When the body is involved in a dangerous physical situation, it protects itself by releasing a surge of adrenaline. This hormone protects the body, causing the fight or flight response when in danger. Adrenaline causes several preservation responses that include:
Intense increase in energy.
Little or no pain.
Enlarged blood vessels and airways increase oxygen flow.
Increased strength from increased blood flow to the muscles.
Changes in vision and hearing that focus on sights and sounds all around.
Endorphins are released that make the body feel calm and in control.
Endorphins affect the way the body responds to pain and stress.
Individuals don’t start feeling aches and pains until the adrenaline and endorphins wear off. However, because everybody is different and the emergency response has turned off, the body still might not feel the injury symptoms. These are delayed injury symptoms.
Rate of Speed
When riding in a vehicle, the body moves at the same speed as the vehicle. During an impact, the vehicle stops, but the body continues moving until it stops, typically with a lot of force from the seatbelt, airbag, or other barriers. The intense momentum change can cause soft tissue damage and ligament or muscle strains from the stretching, pulling, contracting, and tearing. Also, the intervertebral discs can tear, bulge, or herniate over time, creating pressure on nerves and the surrounding tissues.
Delayed Injury Symptoms
Headaches
Headaches that develop days after an accident/crash are common.
They can signal a possible injury to the neck or head, a blood clot on the brain, or a concussion.
Back pain can be caused by injury to the muscles, ligaments, nerves, or damage to the vertebrae.
Low back pain occurs in more than half of rear-impact collisions and almost three-quarters of side-impact crashes.
Chiropractic Rehabilitation
After an accident, soft tissues can sustain minimal damage; however, the minimal damage left untreated can start to worsen and turn into a painful condition. Emergency room visits are to rule out major injuries like brain/nerve injuries, bleeding, punctures, lacerated organs, fractures that require emergency stabilization. Chiropractors look for other symptoms and mechanisms that indicate damage to the body’s soft tissues and nerves to see if they have been stretched or torn and dysfunction in the nervous system.
Body Composition
Calorie Counting
Counting calories can be a stepping stone to change behavior towards food. Tracking what foods are being taken into the body promotes mindfulness of dietary habits. Studies on the subject reveal a significant association between self-monitoring and weight loss. Takeaways include:
Take small steps by saying no to second portions during dinner or take a healthy sweet snack or piece of fruit instead of a pastry, cookie, etc.
Try to start making a habit of eating less processed foods.
Meals high in protein and fiber are generally more filling, making the body feel fuller from fewer calories.
The more attention there is to the food choices, the more likely reexamination occurs.

Chiropractic is a form of neuromusculoskeletal care that repairs and re-optimizes the nervous system that helps to relieve tension, inflammation, pain and restore body health. Like any piece of machinery that requires regular maintenance to operate correctly without issues, so too is the body an exquisite machine that needs regular maintenance. Treatment restores and maintains optimal function to the nervous system, muscles, bones, tendons, ligaments, and joints.

Neuromusculoskeletal Care
Central Nervous System – CNS
The Central Nervous System or CNS is the body’s computer.
It processes functions in the body and mind.
It s made up of the brain and spinal cord.
It helps process external information through sight, sound, touch, smell, and taste.
The CNS interprets sensory information that goes through the spinal cord to the brain, and the body responds accordingly.
It controls voluntary movements like walking, talking, exercising.
It controls involuntary movements like blinking, breathing, digestion.
It allows thoughts, emotions, and perceptions to be created and expressed.
When the Central Nervous System works correctly, the body is coordinated, all senses send and receive information effectively, and cognition/thinking is clear.
Peripheral Nervous System – PNS
The Peripheral Nervous System or PNS transmits signals from the outside to the Central Nervous System.
The PNS is comprised of all the nerve bundles that run throughout the body.
The PNS is responsible for transmitting information back and forth from the CNS to the rest of the body by electrical impulses and current.
When the PNS is functioning correctly, and there is thorough nerve circulation throughout the body, there are no issues like numbness, weakness, pain, and digestion is in top form.
Enteric Nervous System – ENS
The Enteric Nervous System or ENS is a branch of the peripheral nervous system that signals the digestive system.
It comprises nerves that stretch across the entire gastrointestinal tract.
It allows the nervous system to communicate with the digestive tract and regulate activity.
It can stop the digestive process when the body is under stress or strain, i.e., fight or flight response.
Inflammation and stress can cause the enteric system to disrupt and cause digestive problems.
Pain Relief
Body pain can be an indication of an imbalance in the nervous system. Misalignment from work, home activities, trauma, injury, or posture problems, a subluxation/misalignment can turn into discomfort that leads to pain and neuromusculoskeletal system issues. Pain in the neuromusculoskeletal system can result from spinal misalignment and a shifting skeletal structure. The joints and misaligned bones compress the surrounding nerves and tissue, causing inflammation that results in pain symptoms. This causes the muscular system to compensate for the lack of stability support from the skeletal structure causing awkward body posturing. A chiropractor realigns the spinal structure, removing the compression/pressure from the nerves, tissues, muscles, ligaments, and tendons.
Body Composition
Chiropractic Medicine
The nervous system is highly responsive to chiropractic care because of chiropractic’s focus on the spine, which restores and rejuvenates. Chiropractic medicine and a properly aligned spine:
Reduces and eliminates pain.
Reduces and eliminates headaches and migraines.
Improves balance and coordination.
Improves digestive function.
Improves quality of sleep.
Increases energy.
Increases flexibility and mobility.
Enhances cognition and clear thinking.

For older individuals, experiencing frequent low back pain could turn out to be a sacral fracture. They tend to occur in individuals over the age of 60 often because there has been a degree of bone loss. Sacral fractures tend not to be the first thing doctors think of when low back pain symptoms are presenting. They are often not picked up on X-rays and are either not diagnosed early enough to take steps or not diagnosed at all. However, they are common.
Contents
Sacrum
The sacrum is shaped like a triangle and comprises five segments fused into one large bone. It sits at the base of the spine, between the two halves of the pelvis, connecting the spine to the lower half of the body. It stabilizes the body when walking, sitting, or standing. The nerves in the lower spine control the bowels bladder and provide sensation to the region.
The two dimples that can be seen on individuals’ backs are where the sacrum joins the hipbones or the sacroiliac joint.
The point where the low back joins the sacrum can develop discomfort, soreness, and pain.
This area experiences stress from bending, twisting, reaching, lifting, carrying during physical activities or sitting for long periods.
Sacral Fracture
Most sacral fractures result from trauma, like slips, falls, and automobile accidents. Stress fractures that happen without a specific injury are also called insufficiency fractures.
Types of Sacral Fractures
Low-energy fractures usually happen to older individuals with weak bones due to osteoporosis.
An individual trips on something, lands hard on their butt, lifts a heavy object awkwardly, or over-exerts themselves from some physical activity.
Then persistent back or buttock pain begins to present.
The pain is often centered in the lower back, the hips, and butt.
It is more than just back achiness.
The individual goes to the doctor, and X-rays are ordered.
A lot of the time, these fractures are missed on X-rays.
The doctor may diagnose a sprain, but the pain symptoms do not improve.
Sometimes there is no apparent cause for the pain.
It can be misdiagnosed as a lower back compression fracture or urinary tract infection.
High-energy fractures are due to trauma and are more common among the young.
The individual sustains injuries from an auto accident, has fallen from a significant height, or suffers a sports injury.
It results in severe pain.
A woman who has just had a baby and gone through some bone loss because of the pregnancy can experience a sacral stress fracture.
For individuals that have been to a doctor and had an X-ray that reveals no fracture, and there is no improvement after 5 to 7 days, it is recommended to schedule another appointment and ask for a CAT scan or MRI, which is highly effective at finding a sacral fracture.
Treatment
Treatment consists of resting the bone but still being safely active in most cases.
Medication is prescribed for pain relief.
Many individuals have been found to do well with anti-inflammatory medications, topical medications, and lidocaine patches.
Older individuals may be recommended to use a walker during the treatment/healing process.
Depending on the severity, crutches may be recommended.
Engaging in regular exercise is not recommended, but too much bed rest is also not recommended.
Too much rest may not allow the injury to heal correctly, worsen the injury, and/or cause new injuries.
Chiropractic and physical therapy are not recommended to let the sacrum naturally heal.
After the pain subsides, chiropractic and physical therapy can be implemented to maintain agility and flexibility and strengthen the pelvic and core muscles.
In some cases, if the bone does not heal correctly or some other issue, sacroplasty could be recommended. This is a minimally invasive procedure that injects bone cement into the fracture. It offers quick and long-lasting pain relief with a low percentage of complications. It is considered low risk and can be done by an interventional radiologist or spine surgeon.
Prevention
To minimize the risk of a sacral fracture, it is highly recommended to maintain bone strength. This consists of:
Try to keep moving with different exercise stretches, or take a lap around the building.

Stretching Fundamentals: Stretching benefits the body by keeping the muscles flexible, strong, healthy, and able to maintain optimal physical performance. As with any other discipline stretching correctly requires using the proper form, correct technique, and practicing regularly. The angles need to be accurate; the body has to move at the right speed and maintain correct posture. The focus should be moving the joint as little as possible as the muscle/s stretch and elongate.
Contents
Stretching Fundamentals
Stretching should become a daily activity that turns into a healthy habit. The muscles need frequent maintenance from daily/nightly bending, twisting, reaching, carrying, and lifting work. This is especially true for individuals dealing with constant soreness, aches, pains, and problems with tight, tense, and stressed-out muscles. When the body is stressed, heart rate increases, and individuals tend to tighten up. Stretching benefits include:
Stress relief.
Increased muscle blood flow.
Increased body flexibility.
Helps joints move through their full range of motion.
Improves performance in physical activities.
Decreases soreness, aches, and pains.
Injury prevention.
Improves posture.
Improves sleep.
Preps the body for exercise and activities.
Improves mental health.
Human nature is to take the path of least resistance, which makes the body feel flexible and comfortable. This is a common reason individuals consider stretching unnecessary or too painful to engage in. However,stretching fundamentals need to be maintained as stretching carelessly or poorly can negatively affect other muscles and joints and worsen injuries/conditions.
Guidelines
To stretch safely, it is recommended to do a proper warm-up, stretch slowly, working the right muscles and joints. The guidelines make stretching safer, more effective, and increase body awareness.
Warm-Up
Warming the muscles increases blood flow.
Warming up muscles before physical activity/workout is crucial for preventing injuries and maximizing effectiveness.
Dynamic stretching involves moving into and out of positions through a full range of motion rather than holding a stretch for a prolonged period.
Dynamic stretches are recommended to be held for 2-3 seconds for 4-6 repetitions.
Take It Slow
Stretching out too fast can make the body think that the muscle is about to get torn or injured.
To protect the muscle, it contracts, preventing it from reaching the full stretch.
This is why the correct technique needs to be observed.
A couple of degrees in the wrong direction can mean the difference between a healthy stretch and pulling a joint capsule causing injury.
Body Composition
Muscle Recovery
When engaged in physical activity, exercise, or working, microscopic tears are happening to muscle cells. Because of the body’s stress and fatigue, hormone and enzyme levels fluctuate, and inflammation increases. This helps in fat loss, increases metabolism, increases strength and muscle growth. However, these benefits only happen with proper recovery. Different types of recovery include:
Immediate Recovery
These are the quick moments’ in-between physical movements.
For example, the time between each stride when jogging.
Short-Term Recovery
This is the time between activities or sets of exercises.
For example, the rest periods between doing a heavy job or sprint intervals.
Training Recovery
This is the time between when one workout or job ends, and the next begins.
There is no one size fits all, as everyone’s body is different; it is recommended to consult with a trainer or fitness expert and experiment with what feels right.
For some individuals, 24 hours is enough.
For others, it can take 48 or 72 hours to feel fully recovered.
Other factors that affect recovery are:
Age
Fitness level
Work/exercise intensity
Diet
Sleep

The hips are highly active joints. Hip sprains are rare but do occur. A hip sprain is caused by tearing or stretching the ligaments that surround the hip and join the bones to each other. This is different from a hip strain, which is an injury to the muscles and is generally caused by over-use of the hip flexor muscles and tendons, causing them to tear. Hip sprains usually happen after a fall or a sudden twisting motion, which can occur during sports or an accident.
Individuals involved in sports that require quick stops, body shifting, and sudden direction changes, like soccer, football, basketball, tennis, volleyball, etc., have an increased risk. Most hip sprains can be effectively treated with conservative treatments like self-massage, rest, ice, and nonsteroid anti-inflammatory medications. For more severe cases, physical therapy and chiropractic can treat the condition.
Contents
Hip Sprain Symptoms
Tenderness in the hip increases when lifting the thigh.
Cramping sensation/s in the muscles of the upper leg.
Swelling in the hip or thigh
Bruising in the hip or thigh.
Sudden pain in the hip or pelvis.
Sharp pain in the hip or pelvis.
Pain that worsens when walking, running, or stretching the hip muscles.
Loss of strength in the front of the groin.
Tugging or pulling sensation.
Limping.
Diagnosis
The doctor or chiropractor will:
Look into medical history.
Inquire about symptoms.
Inquire about activities that could cause symptoms.
Perform a physical examination.
Ask the individual to perform a variety of movements to determine what type of injury has been sustained.
Pain in one or both hips might not have anything to do with the hips but a pinched nerve root in the lower back.
Sciatica can develop when certain nerve roots in the lower back are irritated or compressed, causing symptoms to travel down the sciatic nerve and radiate around the pelvis and leg.
X-rays can help rule out hip stress fractures, which can have similar symptoms.
MRI or CT scans are used to see if any soft tissue damage has occurred.
Hip Sprain Treatment
Treatment usually begins with over-the-counter pain medications and anti-inflammatories to reduce swelling and relieve pain.
Resting the hip will help prevent further damage.
Applying ice will help prevent tissue damage and reduce swelling.
It is recommended to use an ice pack several times a day for the first 48 hours after an injury.
Once the swelling goes down, a chiropractor and physical therapy team will create a personalized treatment plan that includes:
Adjustments.
Exercise therapy.
Posture training.
Stretching.
Massage.
Treatment/Rehabilitation Objectives
Reduce inflammation.
Relax muscle spasms.
Strengthen weakened muscles.
Improve joint mobility.
Individuals will be shown how to prevent the risk of sprains in the future. This includes:
Avoiding exercising when the body is tired
Wearing proper footwear and protective equipment
Warming up properly before exercise/physical activities.
Depending on the severity of the sprain, surgery could be the last resort to repair the ruptured or torn ligaments.
Body Composition
Realistic Goals
Not seeing results after putting in the work through exercise and diet can be frustrating. Setting realistic goals can help when results are not showing.
Realistic Fat Loss
Do not expect actual fat loss without being in a caloric deficit.
The body needs to use more energy than the amount of food/energy taken in; otherwise, excess energy/food gets stored, primarily as adipose tissue.
There are caloric deficit variations, but most doctors, dieticians, trainers, and fitness experts agree that a caloric deficit of around 500 calories a day that equals to about 3,500 calories a week will result in a pound of fat loss per week.
One pound of fat a week lost might seem slow, but the one pound of fat is a real pound removed.
The long-term goal is not to fall back into unhealthy habits and develop and maintain new healthy ones.

Tremors are extremely rare, but they can result from spinal compression and not necessarily a brain condition like Parkinson’s disease. Tremors are abnormal, involuntary body movements with various causes, most of which are connected to the brain and not the spine. A study reports that more than 75% of individuals with Parkinson’s experienced a resting tremor, and about 60% experience tremors while moving. Sometimes the spine is the contributor caused by compression of the spinal cord.
Contents
Spinal Compression Study
A 90-year-old man was hospitalized after having tremors, with Parkinson’s being the initial diagnosis. The tremors progressed to the point where the man could not feed himself or walk without support. The case became the focus of a medical report published by physicians in the Department of Orthopaedic Surgery, Division of the Spine, Singapore Tan Tock Seng Hospital. Along with the tremors, symptoms progressed to:
Difficulty with fine motor skills like buttoning a shirt.
However, it was ruled out because the patient was not presenting with other Parkinson’s symptoms.
For individuals with cervical spondylotic myelopathy tremors, surgery can be used to help the condition. However, with cervical myelopathy, there is often some permanent damage. Individuals have shown that post-surgery and decompression, symptoms still present, maybe not as much, but there will be a need for a symptom management plan.
Prevention
The best way to prevent tremors associated with cervical spondylotic myelopathy is to minimize the strain on the spine that can lead to herniated discs and/or other spinal injuries. The discs in the spine degenerate, dry out and start cracking with age, increasing the risk of rupture. If a tremor develops, contact a doctor, spine specialist, or chiropractor to help diagnose the condition. These doctors can perform physical and neurological tests to determine the cause and treatment options.
Body Composition
Aging Health
Steady weight gain throughout life can lead to adult-onset diabetes. This is partly caused by having more body fat and progressive muscle loss. Loss of skeletal muscle mass is linked to insulin resistance that involves:
The less muscle is available, the less insulin sensitive the body becomes.
As insulin sensitivity decreases, the body becomes more resistant, increasing risk factors for type II diabetes.
This can lead to osteoporosis, where the old bone is reabsorbed more and less new bone is created.
Both men and women can experience decreased muscle mass that can lead to:
Thinner bones
Weaker bones
Increased risk of osteoporosis and severe injury from falls.
To help prevent these issues, it is recommended to:
It is recommended to space out protein intake across meals rather than consuming it all at once. This helps to ensure the proper amount is acquired.
Monitoring body composition regularly can help minimize muscle mass loss and fat mass gain as the body ages.
A regular strength training routine will help strengthen bones muscles and maintain optimal circulation.

Squat exercises are highly effective, as they strengthen the back and core muscles, helping the prevention of injury. They can be done anywhere with or without equipment like weights and resistance bands and can be part of an aerobic workout. Squatting requires following proper form and posture. Using the improper form, adding too much weight too soon, overdoing it without enough recovery time can cause soreness, back pain, and injury. Having muscle soreness after performing squats is expected; however, if symptoms like chronic soreness, tingling, numbness, or sharp aches that come and go, begin to appear, it is recommended to consult a medical trainer, chiropractor, doctor, or spine specialist to evaluate the symptoms, and if necessary develop a treatment plan, as well as a prevention plan to continue exercising safely.

Squat Exercises
Squatting is a highly beneficial form of exercise. Athletes, trainers, coaches, and individuals just staying healthy use the technique as a part of their training and workouts. This is because squatting increases core muscle strength, increasing body power. Squat exercises benefits include:
Increased Flexibility
Improved strength and a range of motion allow the body to move flawlessly in various directions with minimal effort.
Increased Core Strength
All major muscles work together during a squat.
This increases muscle stabilization, maintains body balance, increasing core strength.
Injury Prevention
Squats work all leg muscles simultaneously, synchronizing the body.
This increases body stability decreasing the risk of injury.
Back Pain and Potential Injury
The spine is exposed and unprotected during a squat. This is where back pain and injury can happen. Potential causes include:
Priming each muscle is recommended. This could be:
Starting with glute work.
Then planks to activate the core.
Finish off with stretching and range of motion exercises.
A personal trainer can assist in creating a customized workout routine.
Starting Position
The feet should always face forward to protect the hips and knees when beginning a squat.
If the feet face at an angle, the form can be impacted, leading to back pain or collapsing arches.
Spinal Alignment
Maintaining a straight-ahead or upward gaze, which increases center awareness during squat exercises, can prevent the body from leaning forward and placing stress on the spine.
Only squat as far as possible, making sure to feel in control and maintain the form.
Squatting too deep can cause muscle strain leading to pain.
Focus on form, as it is more important than depth.
Joint mobility
Ankle mobility and stability are essential to balance and control.
If the ankle is compromised, the feet could lift off the floor, forcing the body to compensate, leading to strain and potential injuries.
Barbell back squats are more advanced and, if done incorrectly, can cause injury.
A chiropractor or physical therapist will be able to evaluate spinal health, exercise form, and advise if there is an issue.

Don’t engage in workouts or fitness programs that make you miserable. Do workouts/activities that you enjoy and have fun doing. Exercise for the love of the body, keeping it healthy and in shape, not because there is a feeling of obligation.
Individuals who don’t like lifting weights try using resistance bands or bodyweight exercises.
The same goes for nutrition. Don’t base diet and supplement choices on misperceptions about health.

Sports-specific performance training is an approach to develop an athlete’s full potential in their sport. This involves three different factors: physical, technical, and experience. Physical ability is the exercise physiology that consists of strengthening and conditioning the body to handle the conditions of the sport. This includes:
Strength
Power
Speed
Endurance
Mobility
Stability
Flexibility
Balance
Technical ability involves the skill sets needed for the sport. This includes:
Running
Jumping
Kicking
Throwing
Catching
Hitting
Sliding
And finally is the athlete’s experience. This takes the knowledge, combined with the physical and technical abilities brought together to perform at optimum levels. However, it all begins with physical ability that needs to be developed. Even naturally gifted individuals need to develop their physical ability.

Sports Specific Performance Training
Strength & conditioning objectives are to develop the whole athlete. This involves:
An athlete’s health takes into consideration their body composition and current or past injuries. Along with injuries, the athlete’s mobility, flexibility, and stability are examined to determine if these were among the contributors or conditions that caused or could lead to an injury. Strength & conditioning is used so an athlete can return to play and allow them to be more resilient to injuries. Maintaining the body’s health means:
Keeping track of nutrition by making healthy food choices.
Maintaining proper hydration levels.
Allowing the body to recover from training thoroughly.
Keeping the body loose and flexible through chiropractic sports massage or a personal training therapist.
Stability is the coordination of muscle action that allows a joint to remain in the proper position during movement.
If an athlete is mobile and flexible but not stable, it increases the risk of sustaining an injury. The same can be said of an athlete with stability but limited mobility.
Athletic Mindset
An athlete’s mindset can win or lose games.
Athletes are encouraged to push themselves to see what they are capable of, which relies on mental strength.
Athletes that doubt their ability become their own worst critics and hold themselves in low self-esteem tend to underperform or become overly cautious when competing.
This is where a sports psychologistcan help an athlete overcome any confidence issues.
Athleticism
Developing athleticism involves strength, power, speed. These physical attributes allow athletes to perform within their technical and strategical abilities.
It is recommended to spend 10-15 minutes warming up with each sports-specific performance training session. The warm-up:
Speed training addresses linear, lateral, and multi-directional speed. The objective is to keep athletes learning and developing better reaction skills while maintaining high-quality movement. Speed training can last 10 to 15-minutes with the number of repetitions.
Strength training follows an individualized system for each athlete based on an initial evaluation. The objective is to eliminate any weaknesses that an individual may have and develop functional strength, giving the athlete the ability to take that strength onto the field, court, mat, etc.
It is essential to understand how the body moves. Kinesiologyand programming parameters involve – sets, repetitions, overall training volume, and the body’s response to the stimulus.
Body Composition
Exercise and Blood Pressure
Blood pressure typically rises naturally as the body ages. The American Heart Association recommends individuals get at least 150 minutes of moderate-intense aerobic exercise or 75 minutes of vigorous aerobic activity each week. This can be split up into 30 minutes per day on at least five days a week or in 10 minute short sessions throughout the day. Aerobic exercise can include:
Walking
Dancing
Running
Cycling
Hiking
Swimming
Resistance Training
Research suggests that resistance training with bands or weights can supplement aerobic exercise to reduce blood pressure. It is recommended to complete 2 to 4 sets of 8 to 12 repetitions for each major muscle group during workouts. It is recommended that resistance training be spaced out throughout the week to limit the potential muscle soreness that can lead to injury. Resistance training can include:
Weight machines like chest press, shoulder press, etc.

Neuroregenerationcould become an option for spinal cord injury treatments in the future. A spinal cord injury or SCI is when there is damage to the bundle of nerves and cells that send and receive signals from the brain and body. A spinal cord injury can be caused by direct trauma/injury to the cord or damage to the tissue and vertebrae. The damage can result in temporary or permanent changes in:
Sensation
Movement
Strength
Body function/s below the injury site.
There are incomplete and complete injuries. Injuries that cause limited or no cell death can achieve a full recovery. Injuries that are more serious and/or are higher on the spinal cord can cause permanent damage and/or paralysis. Automobile crashes, accidents, and serious falls are the most common causes of spinal cord injuries.
An incomplete injury means the cord can still transmit messages, but there is interference/disturbance.
A complete injury means communication and motor function/voluntary body movement is not transmitting.
Contents
Symptoms
Symptoms of a spinal cord injury include:
Unnatural or awkward positioning of the spine or head.
Pain or pressure in the head, neck, or back.
Numbness
Tingling
Loss of or changes in sensation in the hands and feet.
Problems with walking.
Weakness or inability to move parts of the body.
Loss of movement.
Paralysis can occur immediately or develop over time as swelling and bleeding affect the cord.
Loss of bladder and bowel control.
Changes in sexual function.
Difficulty breathing.
SCI Damage Control
A spinal cord injury affects the central nervous system, the body’s central headquarters. Damage can cause complications through what’s called the secondary injury cascade, which is a series of chemical reactions the body activates to help the situation. However, if the chemical response does not stop and stays active, it can worsen the injury. The body recognizes that an emergency has occurred and tries to go into a shut-down mode that kills off some of the cells in the central nervous system. When a spinal injury happens, treatment focuses on stopping the damage as quickly as possible to stop the injury cascade and prevent as much cell death as possible. This act is called neuropreservation, meaning that the team is trying to preserve and save as many nerve cells as possible.
Injury Neuroregeneration Treatment Studies
While current treatment primarily focuses on stopping as much damage as possible then going through physical therapies to maintain spinal alignment and rehabilitate the body, the future of injury treatment is looking towards regrowing and repairing the damaged nerve cells through a process known as neuroregeneration. Repairing nerves that have been damaged could change life for many. Neuroregeneration Treatments being studied include:
Surgery
A study in The Lancet Neurology presents how getting surgery as soon as possible after an injury can provide significant benefits.
The findings could change all of the guidelines for spinal cord injury.
Medication
A study on Riluzole, a medication that has shown promise to slow down nerve cell damage.
A team completed a randomized controlled trial for the medication; soon, the final results will be available.
Scientists are studying ways to grow new nerve cells from an individual’s stem cells without the need for embryonic stem cells.
Specialized stem cells could also be used to help other nerve cells regenerate.
Electrical stimulation
Another approach is using electrical stimulation to restore function in the spinal cord.
Therapy that could help a paralyzed individual walk again.
The Future of Neuroregeneration
Aside from early surgery intervention, most neuroregenerative treatments are not ready or accessible yet. There’s still much more research before it can become a mainstream treatment option. Treatment that involves regenerating nerve cells will take longer than a treatment designed to protect nerve cells. However, more clinical trials are expected to be done in the next few years, with stem cell therapies taking the longest. Some of these therapies could be ready to be used on actual patients in 5-10 years.
Body Composition
The Importance of Measuring Body Composition
Most diet and fitness programs focus on weight loss or gain. However, they tend to overlook that individuals have completely different body compositions. Body composition describes the amount of:
Fat
Bone
Water
Muscle
In the body.
Measuring body composition can tell a body’s unique makeup and help identify areas to work on to improve overall health and wellness. Body composition analysis provides a snapshot of an individual’s health/fitness levels to help achieve health goals from the inside out.
