Can improving breathing patterns help further fitness and optimize overall health for individuals who walk for exercise?
Improve Breathing and Walking
Exercising is a moment in which breathing can quicken and become labored if not done correctly. There is a proper way to breathe when exercising, especially when walking or speed walking. Breathing incorrectly causes rapid fatigue and exhaustion. Controlling the flow of one’s breath improves endurance and cardiovascular health, and it can also amplify metabolism, mood, and energy levels. (Hsiu-Chin Teng et al., 2018) Known as diaphragmatic breathing, it is used for those with reduced lung capacity, like individuals with chronic obstructive pulmonary disease/COPD. The practice improves lung capacity and is a recommended way to help relieve stress.
Physiology
During exercise, the oxygen inhaled converts the calories consumed into energy that fuels the body. This process is referred to as metabolism.
When the oxygen supply exceeds the body’s oxygen needs, the body is in an aerobic state. This means there is plenty of oxygen to fuel physical activity/exercise as there are calories to burn.
If the oxygen supply falls short of the body’s oxygen needs, the body falls into an anaerobic state.
Deprived of oxygen, the body turns to stored fuel in the muscles, known as glycogen.
This delivers a powerful burst of energy, but the fuel is quickly spent and fatigue and exhaustion soon follow.
Increasing airflow in and out of the lungs can prevent early exhaustion and help the body burn calories more effectively. (Your lungs and exercise. Breathe 2016)
Improved Breathing Benefits
Optimal breathing starts in infancy. When a baby breathes, their belly rises and falls. This facilitates respiration by pushing and pulling the diaphragm – the muscle that separates the lungs and abdominal cavity. When the baby inhales, the belly extends, pulling the diaphragm downward and allowing the lungs to fill with air. When the baby exhales, the belly draws in, pressing the diaphragm upward and forcing air out. As the body ages and the capacity of the lungs increases, individuals shift from belly-breathing to chest-breathing. Chest breathing involves the chest wall muscles with little use of the diaphragm. Chest breathing usually provides enough air for everyday activity but does not fill the lungs.
This is why individuals resort to mouth-breathing or gasping when the oxygen supply is limited. Even those in decent physical shape may be inadvertently undermining efforts by sucking in their stomach to look thinner, depriving themselves of complete inhalations and exhalations. To overcome this, individuals need to re-train their bodies to activate the abdominal muscles when walking. Belly or diaphragmatic breathing can extend the duration of exercise while strengthening the core muscles. (Nelson, Nicole 2012) By increasing core stability, individuals can better support the spine and maintain a healthy posture when walking. This stabilizes the hips, knees, upper back, and shoulders, making the body less prone to strain, instability, and fatigue from unhealthy posture. (Tomas K. Tong et al., 2014)
Breathing Correctly
The inhalation draws the belly out, pulls the diaphragm down, and inflates the lungs. Simultaneously, it extends the ribcage and lengthens the lower spine. This forces the shoulders and collarbone backward, further opening the chest. Exhaling does the reverse.
Walking
Start by inhaling and exhaling through the nose, ensuring that the inhalation duration matches the exhalation duration. When picking up the pace, individuals can resort to mouth-breathing, maintaining the same inhalation/exhalation rhythm. At no time should breathing be held in. Learning diaphragmatic breathing takes time, but the following steps can be a starting point:
Inhale by inflating the belly fully on a count of five.
Allow the lungs to fill, drawing the shoulders back as this happens.
Exhale by pulling the belly button toward the spine on a count of five.
Use the diaphragm to press the air out of the lungs, keeping the spine erect.
Repeat.
If unable to maintain a count of five, individuals can shorten the count or slow the pace of the walk. Individuals in good shape may be able to extend the count. Initially, diaphragmatic breathing may not come naturally, but it will become automatic with practice. Stop and place the hands over the head if short of breath when walking. Breathe in and out deeply and evenly until breathing returns to normal.

Individuals trying to get and stay in shape can find it difficult to get a regular workout. Can jumping rope help when there is no time?
Jumping Rope
Jumping rope can be a highly cost-effective exercise to incorporate high-intensity cardiovascular fitness into a workout routine. It is inexpensive, efficient, and done properly can improve cardiovascular health, improve balance and agility, increase muscular strength and endurance, and burn calories. (Athos Trecroci, et al., 2015)
Jumping rope can be utilized in interval training to keep the heart rate elevated and allow the muscles to rest in between weight lifting and other intense exercises.
A jump rope can be used when traveling as its portability makes it a top piece of workout gear.
It can be combined with bodyweight exercises for a dependable and portable exercise routine.
Benefits
Jumping rope is a medium-impact exercise with benefits that include:
Improves balance, agility, and coordination
Builds stamina and foot speed for coordination, agility, and quick reflexes.
Variations include one-leg jumping and double unders or with each jump, the rope goes around twice to add difficulty.
Builds Fitness Fast
Burns calories
Depending on skill level and jumping rate, individuals can burn 10 to 15 calories a minute by jumping rope.
Faster rope jumping can burn calories similar to running.
Precautions
For individuals who have high blood pressure, jumping rope may not be recommended. The downward arm position can reduce blood circulation back to the heart which can further increase blood pressure. Studies have shown that jumping at a moderate intensity is beneficial for individuals who are pre-hypertensive. (Lisa Baumgartner, et al., 2020) Individuals with hypertension and/or a heart condition, are recommended to discuss the potential risks with their doctor before beginning a new exercise routine.
Choosing a Rope
Jump ropes are available and made from various materials and come with different handles.
Some of these materials help jump ropes spin faster with a smooth motion.
Some options have a swivel action between the cords and handles.
The rope you buy should be comfortable to hold and have a smooth spin.
Weighted jump ropes can help develop upper body muscle tone and endurance. (D. Ozer, et al., 2011) These ropes are not for beginners and are not necessary for an agility workout.
For individuals who want a weighted rope, be sure the weight is in the rope and not the handles to prevent straining the wrists, elbows, and/or shoulders.
Size the rope by standing on the center of the rope
Pull the handles up along the sides of the body.
For beginners, the handles should just reach the armpits.
As the individual’s skills and fitness develop, the rope can be shortened.
A shorter rope spins faster, forcing more jumps.
Technique
Following proper technique will ensure a more safe and effective workout.
Start slowly.
The proper jumping form keeps the shoulders relaxed, elbows in, and slightly bent.
There should be very few upper-body movements.
The majority of the turning power and motion come from the wrists, not the arms.
During jumping, keep the knees slightly bent.
Bounce softly.
The feet should leave the floor just enough to allow the rope to pass.
Land softly on the balls of the feet to avoid knee injuries.
It is not recommended to jump high and/or land hard.
Jump on a surface that is smooth and free of obstacles.
Wood, a sports court, or a rubberized mat are recommended.
Warming Up
Before beginning jumping rope, do a light, 5 to 10-minute warm-up.
This can include walking or jogging in place, or slow-paced jumping.
Increase Time and Intensity Gradually
The exercise can be relatively intense and high-level.
Start slowly and increase gradually.
An individual might try three 30-second sets at the end of a routine workout for the first week.
Depending upon fitness level, individuals may feel nothing or some slight soreness in the calf muscles.
This can help determine how much to do for the next jump rope session.
Gradually increase the number of sets, or the duration, over several weeks until the body can go for about ten minutes of continuous jumping.
One way is to jump after each weight-lifting set or other circuit exercise – like adding jumping for 30 to 90 seconds in between exercise sets.
Both feet slightly lift off from the ground and land together.
Alternate foot jump
This uses a skipping step.
This allows landing more prominently on one foot after each spin.
Running step
A slight jog is incorporated while jumping.
High step
A moderate pace with a high knee raise increases intensity.
Rope jumping is a great addition to an interval training or cross-training routine that creates an efficient whole-body workout that incorporates both cardiovascular endurance and muscular strength.

Tennis requires strength, power, and endurance. Can combining tennis weight training into a player’s fitness regimen that is broken up into phases achieve optimal results?
Tennis Weight Training
In professional sports that utilize weight lifting, the training is often broken up into seasonal phases. (Daniel S Lorenz, Michael P Reiman, John C Walker. 2010) Each phase consists of specific objectives that contribute to and build upon the previous phase. This is known as periodization. Tennis is played year-round indoors and outdoors. This is an example of a tennis weight training program to build up strength.
Pre-Season
In the early pre-season, players prepare to rebuild their strength after a break.
The emphasis is on building functional strength and some muscle.
Late Pre-Season
In late pre-season, players workout to get ready for the start of the season.
Here, the emphasis is on building maximum power.
In Season
In season, regular practice, play, and competition get underway and players are in top condition.
In this phase, strength and power maintenance is the focus.
Season Break
This is when players need to relax for a while.
However, players need to keep active if they want to maintain some level of fitness.
The emphasis is on rest and recovery with the maintenance of light activity, like cross-training and light gym workouts.
Research has shown that taking a break from serious strength training does help the body recover and rebuild. (Daniel Lorenz, Scot Morrison. 2015)
This is a three-phase all-around program.
The first phase concentrates on building basic strength and muscle
The second phase on power delivery.
Players who play year-round can continue with the power program once they build the basics.
Players who take a break for longer than six weeks should start again with the strength program.
Pre-Season – Phase One
Strength and Muscle
The focus is on lifting heavy weights, but not going full force to begin training the nervous system to work with the muscle fibers.
Some muscle building or hypertrophy/building muscle size will happen during strength development.
Strength is the foundation for the power development phase.
Exercises:
Duration: 6-8 weeks
Workout Days: 2-3, with at least one day, however, two are recommended between sessions.
Reps: 8-10
Sets: 2-4
Rest between sets: 1-2 minutes
Barbell squat, dumbbell squat, or sled hack squat
Romanian deadlift
Dumbbell bent-over row
Dumbbell triceps extension or machine pushdown
Cable wood chop
Lat pulldown to the front with a wide grip
Reverse crunch
Things to Remember
Use the Proper Weight
Adjust the weight so that the last reps are heavy but don’t cause a complete failure.
Balance the Lower Half
The posterior chain of the hips, the gluteals/buttocks, the upper legs, and the abdominals are of equal importance and require equal attention. (Eline Md De Ridder, et al., 2013)
Squats and deadlifts build strength and power in this region.
Follow Proper Form
For upper body exercises like the dumbbell press, lat pulldown, and wood chops the proper form needs to be followed.
Keep the forearms in a vertical plane with the upper arms.
Do not extend excessively at the bottom of the movement.
Remember to protect the vulnerable shoulder joint.
Listen to The Body
Strength training is physically and mentally challenging.
Individuals who are not able to recover from a session with only one rest day are recommended to move the program to two sessions per week.
Muscle soreness or delayed onset muscle soreness – DOMS – is normal, however, joint pain is not.
Monitor arm and shoulder reactions during this phase.
Stop if any joint pain or discomfort is felt.
Late Pre-Season – In-Season – Phase Two
Power
Power is the ability to move the heaviest loads in the shortest time and is the combination of strength and speed. In this phase, the player builds on the strength developed in phase one with tennis weight training that will increase the ability to move a load at high velocity.
Power training requires lifting weights at high velocity and with explosiveness.
The body needs to rest adequately between repetitions and sets so that each movement is done as fast as possible.
The number of sets can be less than phase one because there is no point in training at this level when the body is fatigued.
Exercises
Duration: Ongoing
Days per week: 2
Reps: 8 to 10
Sets: 2-4
Rest between repetitions: 10 to 15 seconds
Rest between sets: at least 1 minute or until recovered
Barbell or dumbbell hang clean
Cable push-pull
Cable wood chop
One arm cable raises
Medicine ball push press
Medicine ball standing twist with a partner or alone – 6×15 repetitions fast and recover between sets.
Reminders When Preparing For the Season
Recovery Time
In power training, it’s important that the body has relatively recovered for each repetition and set so that the individual can maximize the movement.
The weights should not be as heavy and the rest periods sufficient.
Push When Possible
Rest is important, at the same time, the player needs to push through reasonably heavy loads to develop power against significant resistance.
When doing medicine ball twists, do a full set at maximum, then sufficiently rest before the next one.
If doing the medicine ball exercises alone, use a lighter ball and keep the ball in your hands while twisting.
In Season – Phase Three
When the season begins training does not stop in order to help maintain strength and power.
Strength and Power Maintenance
Alternate phase one and phase two for a total of two sessions each week.
Every fifth week, skip weight training to achieve optimal recovery.
Key Points
Things to keep in mind during the season.
Avoid Overscheduling
Avoid strength training on the same day when practicing on the court.
If the weight training has to be both on the same day, try to separate the workouts into morning and afternoon sessions.
Plan Time
Rest completely from strength training one week out of every six.
Light gym work is fine.
During the season, use intuition when it comes to working out at the gym.
Individuals with limited time, stick to court skills training instead of tennis weight training.
Off Season
If there is an off-season, this is the time for emotional and physical decompression and full-body recovery.
For several weeks, forget about weight training and do other things.
Stay fit and active with cross-training or other physical activities but keep it light to prevent injuries.
It is recommended to consult a coach, trainer, sports chiropractor, and/or physical therapist to develop a program specific to an individual’s needs, fitness goals, and access to resources.

Fitness, exercising, weight, and strength training programs use terms like sets, reps, and rest intervals. Knowing what they mean and how to use them for optimal results is important to achieve health goals. An individual’s training program will differ in the weights, reps, sets, rest intervals, and execution speed depending on whether the training is for fitness, muscle growth, strength, power, or endurance. Here we offer a strength training guide on understanding these terms and how they apply to a workout program.
Strength Training Guide
Reps
Rep means repetition.
A rep is one completion of an exercise, such as one bench press, or one bicep curl.
So, one bicep curl equals one rep, and 10 bicep curls equals 10 reps.
Reps make up a set, which is typically the total number of reps done before taking a break.
A repetition maximum – 1RM is an individual’s personal best or the most they can lift once in a single repetition.
A 10RM would be the most an individual could lift and successfully perform 10 reps with proper form.
Sets
A set is a series of repetitions performed sequentially.
For example, one set of bench presses could be eight reps
Sets are designed according to the individual’s workout program.
Rest
The rest interval is the time of resting between sets that allow the muscles to recover.
The rest period between sets can range from 30 seconds to two minutes.
Exercises can have short or long rests between reps.
The ideal rest period depends on the objective of the workout and health goals.
Not resting long enough and starting with another set too soon can fatigue the muscles too soon, increasing the risk of injury.
Resting too long between reps can cool the muscles down and release tension before starting again.
Execution Speed
The speed at which one rep of an exercise is performed is contraction velocity.
Concentric – shortening of the muscle is often the lifting part of a rep.
Eccentric – lengthening of the muscle, often the lowering part of a rep helps to build muscle mass.
Strength: 1 to 2 seconds concentric and eccentric
Hypertrophy: 2 to 5 seconds concentric and eccentric
Endurance: 1 to 2 seconds concentric and eccentric
Power: Less than 1 second concentric and 1 to 2 seconds eccentric
Choosing Weights
The distribution of repetitions against a percentage of 1RM maximum lift is as follows. This example uses a bench press where 1RM is 160 pounds.
100% of 1RM: 160 pounds, 1 repetition
60% of 1RM: 96 pounds, warm-up reps
85% of 1RM: 136 pounds, 6 repetitions
67% of 1RM: 107 pounds, 12 repetitions
65% of 1RM: 104 pounds, 15 repetitions
An individual should be able to do one lift at 1RM, six reps at 85%, 15 reps at 65%, and so on.
Goals to Build a Program
A training program is a schedule of exercise types, frequency, intensity, and volume, for weight training or any other type of fitness training. Individuals can devise various combinations of sets, reps, rest, and exercise types to find what works best for them. A qualified strength and conditioning trainer can help develop a program. The variables can be adjusted and include:
Exercise selection
Weights or resistance used
Number of reps
Number of sets
Execution speed
Rest time between sets
Rest time between training sessions and days of the week
General Fitness
A basic strength training fitness program targets strength and muscle-building.
Between eight and 15 repetitions for two to four sets will help achieve both.
Choose eight to 12 exercises, making sure to hit the lower and upper body and core.
Strength
Building strength uses the most weight, the least number of reps, and the longest rest periods.
The neuromuscular system responds to heavy weights by increasing the body’s ability to lift heavy loads.
For example, individuals with a strength goal could use a 5×5 system.
This means five sets of five repetitions.
Muscle Growth
Muscle growth and bodybuilding training use lighter weights, more reps, and less rest periods.
Muscle requires metabolic stress to increase in size.
This means working the muscles to the point where lactate builds and the muscle suffers internal damage, sometimes called “training to failure.”
Then resting and proper nutrition help muscle repair and the muscle grows larger in the process.
A program could be three sets of 8 to 12 reps, with loads that reach or near the failure point on the last few reps.
Power
Power training uses slightly lighter weights, takes longer rest periods, and focuses on execution speed.
Power is the ability to move an object at high speed.
Each push, pull, squat, or lunge is done at a quick tempo.
This type of training requires practicing the acceleration of a lift, resting properly, and repeating.
Muscular Endurance
Endurance weight training requires more reps in each set, up to 20 or 30, with lighter weights.
Individuals should ask themselves what is the day-to-day physical activity that requires the most muscular endurance?
For example, runners will want to concentrate on increasing endurance in their legs.
Swimmers may shift and focus on their arms one day then legs another.

Mountain and trail biking is a fun way to exercise. Mountain biking requires total body/core strength, explosive power, balance, endurance, and agility to maneuver the bike, build speed, and absorb the rough bumps and terrain. But it also means that certain muscles get overused, causing overcompensation in the body that can lead to musculoskeletal problems and conditions. Strength, cardiovascular, and cross-fit can benefit mountain biking training for improved performance, safer and more confident riding, and injury prevention.
Mountain Biking Training
A few of the benefits of training are:
Increasing bone density.
Improving joint health.
Correcting imbalances and unhealthy posture.
Weight loss.
Aging muscle loss prevention.
Maintaining body posture centered on the bike requires core strength to perform the movements when moving the body backward and forwards, side to side, and pushing up and down when different obstacles pop up. The exercises’ objective is to work various body parts simultaneously and diagonally, like the movements used on the bike.
General Overview of Mountain Biking Training
Build strength – Target the quads, hamstrings, and abdominal muscles to power pedaling strokes.
Increase endurance – Avoid getting fatigued early because of weakened legs and aerobic performance.
Improve mountain bike skills – Ride faster and more efficiently by improving bike handling and technical skills.
Example Training Week
The terrain determines the intensity, but the same basic principles apply to mountain biking training as other endurance sports. Here’s a training example for a beginner that can be adjusted to the rider’s needs:
Monday
Stretching and training the muscles to relax prevent becoming stiff or cramping up during rides.
Cornering is a critical skill that should never stop being practiced and improved.
Cornering Drills
Pick a corner on a local trail and ride through it until mastered.
Focus on riding smoothly through the corner, and speed will generate.
As confidence builds in the corners, do the same on the opposite side.
Straighten Out
Ride to the furthest outside edge when approaching the turn.
Initiate the turn just before the sharpest point of the corner.
Stick to the furthest outside point of the corner when riding out of the corner.
Brake Before The Corner
Braking in the corner can cause the tires to slide out of control, causing a slip-and-fall accident.
Look through the turn as the bike follows where the eyes look.
Don’t stare at the front wheel, which could lead to a falling or flipping accident.
Eventually, riders can handle this technique, but it’s too advanced for beginners.
Smooth Ride
Beginners can be amazed at how much terrain bikes can ride over and through. Modern mountain bike suspension and tire systems can handle it. However, using the correct technique is essential to get through or around the obstacles and avoid crashes.
Stay aware of the surroundings.
Keep the body loose when approaching obstacles.
Decide how to overcome the obstacle – ride over, pop/raise the wheels, jump, or ride around.
Maintain confidence.
When riding over the obstacle, maintain an even balance on the pedals and keep the buttocks slightly off the saddle.
Keep arms and legs loose and let the body absorb the shock of the obstacle.
Trust the suspension and tires.
Ensure enough speed is generated to go over it and that it won’t stop the bike and cause a fall.
Some rough trail areas can require added strength to hold the bike steady.
Braking
There is no need to squeeze the brake handles with extreme force.
Extreme braking, especially the front, will likely lead to a flip or crash.
The brakes are made to stop with minimal force.
Beginners are recommended to learn to use a light touch when braking.
Improvement will follow with each riding session.

Aerobic Exercise Health: The body adapts differently to different types of exercise. Aerobic, cardio, and endurance all refer to activities stimulating heart and breathing rates to provide the muscles with oxygenated blood. The oxygen is delivered by blood pumped from the heart through the arteries and returns to the heart through the veins. This explains all the heavy breathing during workouts. Aerobic exercise increases energy production in the muscle cells and blood delivery in the cardiovascular system.
Aerobic Exercise Health
The Heart
All the muscles get to rest on and off when in use. The heart is a unique muscle that pumps blood through the body that never gets time off. This is why it is important to strengthen the heart. With aerobic exercise, the heart’s chamber/left ventricle gets larger, producing more blood per pump to the rest of the body. This improves cardiac output for the blood pumped by the heart per minute. When the heart is stronger, pumping more blood per beat means it doesn’t have to beat as rapidly. A lower resting heart rate is associated with a reduced risk of cardiovascular disease and promotes long and healthy life.
Vascular
Each time the heart beats, blood pumps from the left ventricle into the aorta and flows into a branching vessel network. Every artery in the body provides resistance to the circulation that the heart pushes against. The resistance provided can vary, depending on overall health and health conditions.
Aerobic exercise training reduces the workload by reducing arterial stiffness.
Aerobic exercise increases heart rate, pushing more blood through the arteries.
The inner wall of the arteries recognizes the increased blood flow causing the arteries to widen.
With regular training, the arteries acclimate and become more effective at expanding with each rush of blood.
No aerobic activity can cause the arteries to stiffen, causing circulation problems.
Aerobic exercise impacts the vascular system by promoting capillary growth.
Capillaries are microscopic vessels where oxygen diffuses from red blood cells to the muscle and other cells.
The body stimulates a molecule called vascular endothelial growth factor to grow additional capillaries to regulate energy demand more efficiently.
Older individuals benefit from aerobic activity similarly to young individuals.
Metabolic
Along with cardiovascular benefits, aerobic exercise increases the muscles’ energy production. The energy is produced in muscle cells primarily through an oxidative energy system. Oxidative energy production takes place within cells called mitochondria. Once blood delivers oxygen to the muscle cells, it can be used to produce energy that powers the muscles.
Aerobic exercise training improves the muscle cells’ ability to burn fat by generating more mitochondria and enhancing functionality.
Following each training session, the body burns more fat than usual.
Aerobic training can increase resting metabolic rate, resulting in more calories burned.
It can increase post-exercise oxygen consumption/EPOC, resulting in increased calorie burn after training in addition to calories burned during exercise.
Muscle
The muscles adapt from aerobic training. Muscles are made up of various fiber types.
Aerobic exercise training primarily influences type 1 fibers, known as slow-twitch fibers.
The name comes from the proteins responsible for their contractions.
Relative to type 2a fibers/fast-twitch, type 1 fibers contract more slowly but have an increased capacity to contract over and over for longer.
Aerobic training results in hypertrophy of type 1 muscle fibers by adding more slow-twitch proteins.
Strengthening the heart and making arteries more flexible directly impacts health and physical function. Aerobic exercise strengthens and trains the heart to circulate blood efficiently.

All sports differ in the relative importance of various physical skills contributing to the game and individual performance. Baseball is a precision sport with fast, explosive movements and full-body activity. The ability to repeatedly perform near maximum level with little rest is necessary for baseball players. Baseball training involves a multidimensional approach that focuses on speed, agility, and strength in a way that is relative to the motions and requirements of the sport.
Baseball Training
Trainers have to assess the unique needs of the sport and determine the time needed to improve each quality within the athlete. They should focus on the following:
Baseball training workouts are targeted at increasing running speed, bat speed, pitching, and throwing velocity that breaks down the muscle groups for improving performance while decreasing the risk of injury. Training consists of combined conditioning that includes:
Throwing a baseball at high velocity is a full-body movement that requires total body development.
Strong leg, hip, and core muscles are necessary to transfer power from the ground, up through the lower body, to the torso, and then the arm and hand to generate a fast, whipping ball release.
This will improve generating power in the throwing muscles.
The objective is to build power utilizing a heavy and then a light load to build arm speed, and using proper form will improve throwing velocity safely.
Proper trunk rotation during arm cocking and strength and flexibility training should involve trunk rotational exercises to develop the obliques so that maximum arm speed can be generated.
Players have to deal with consistent failure and remain confident.
