Power is the combination of strength and speed over time. Strength is how much force an individual can exert. Powerishow fast an individual can exert force. Strength training for power, aka power training, is being able to exert a certain amount of force in a given time. Power can be built with weight training. However, power strength training is not just for weightlifters. Many athletes like football, basketball, and volleyball players, sprinters, dancers, and wrestlers build strength to increase power, improve explosiveness, increase their vertical leap/jump, and give their bodies a break from heavy weight training.
Power Strength Training
Building strength is one factor, but becoming powerful requires another element in training. Biologically, individuals train the muscles to elongate and contract fast so the body can perform a certain set of movements.
Benefits
The benefits of power strength training.
Promotes Active Body Rest
Power training gives the mind and body a break from heavy training.
Provides the tendons, joints, and central nervous system a rest.
Offers a fun and healthy change with jumping, throwing, swinging, etc.
A study found individuals with knee osteoarthritis that participated in high-intensity strength training, compared with low-intensity, had a reduction in knee pain symptoms.
Improves Vertical Jump
Vertical jump or leap is how high an individual can jump and is a common parameter for assessing athletic ability.
It is an integral part of movement training programs to improve sports performance.
Research has shown that power strength and jump training can improve jump height.
Training Program
Before starting any exercise program, it is recommended to talk with a doctor. Key components to focus on when training for power.
Going above this frequency can be intense on the body and central nervous system.
Limiting sessions to a few times a week gives the body time to recover.
Equipment
Because power training involves a combination of increasing force and speed, using the right equipment that allows both is important. However, there are ways to improve without equipment.
For practicing jumps, increase the force by increasing the distance using a taller box.
For practicing push-ups on the floor, increase the force by pushing with more power so the hands come off the ground.
To improve power by increasing speed, exercises can be performed faster or with decreased rest between sets.
Weight
The weight depends on an individual’s one-rep max or the heaviest weight that can be lifted in a single repetition.
This is essentially an individual’s record for whatever type of weightlifting is being done.
Power training movement options: Plyometrics, Ballistic, or Dynamic.
Plyometrics includes activities like squats or jump lunges, common with football and basketball players.
Ballistic training includes activities like a back squat for football or soccer players.
Dynamic training works for sports-specific training motions like golf swinging or tennis serving.
Nutrition
Whether cardio or strength training, adequate caloric intake is important regardless of workout type, this means having a healthy balance of the three macronutrients: carbohydrates, fat, and protein.
Carbohydrates could be the most important, as research has shown that high-intensity exercise like power training improves when eating carbohydrates before, during, and after the workout.
Fat is necessary, and a daily intake below 20% of calorie intake can decrease the absorption of various essential nutrients.
It is recommended to consume 1.2-1.7 grams of protein per kilogram of individual body weight.
As with any exercise, training takes time, and it’s important to gradually progress only when the body is prepared. Incorporating the elements of a healthy lifestyle includes a balanced, nutrient-rich diet and proper sleep and rest days. This will help get the most benefits and prevent injuries.

Delayed Onset Muscle Soreness – DOMS is when muscle pain or stiffness develops a day or two after playing sports, weight lifting, exercise, or work that involves concentrated physical activity like lifting and carrying objects. DOMS is considered a normal response to extended exertion and is part of the adaptation process that the recovering muscles experience as they undergo hypertrophy or an increase in muscle size. It is common in individuals who have just started exercising, increased the duration or intensity of their workouts, or just beginning a physically demanding job.
DOMS
When muscle contracts as it lengthens is known as eccentric muscle contractions, which is most associated with DOMS. It is related to increased stress in muscle fibers as they are exerted excessively. This also happens when engaging in movements the muscles are not used to, like a new exercise or helping a friend move heavy boxes, furniture, etc. Examples include:
Individuals will not feel DOMS during the workout or physical activity. Delayed symptoms include:
Swelling in the affected muscles.
Muscles feel tender to the touch.
Muscle fatigue.
Reduced range of motion and movement.
Pain and stiffness when moving.
Decreased muscle strength.
Treatment Options
Time and waiting for the muscles to repair themselves is the natural healing process, but steps can be taken to ease the soreness, stiffness, and pain. This includes:
It is different for everybody; personal experience will determine which works best for the individual.
Active Recovery
Active recovery is a technique that uses low-impact aerobic exercise right after a workout to increase blood flow to the muscles.
The increased blood supply can help relieve the inflammation.
RICE
This technique is used for acute injuries but can be applied to delayed onset muscle soreness. It stands for:
Rest
Ice
Compression
Elevation
Chiropractic
A chiropractic massage is for healing sore muscles, tendons, ligaments after an intense game, workout, etc. Chiropractic increases the blood and nerve circulation around the muscles delivering added oxygen and nutrients. This type of massage helps loosen the muscles/connecting tissues allowing the body to recover and heal quicker.
Body Composition
When Muscles Are Not Rested
Not taking time to recover because of overtraining/working can have consequences on the body. Inflammation that is not given the time to heal can lead to:
Injuries.
Weakened immune system.
Muscle mass loss.
Mental health issues.
The body’s immune system cannot function at total capacity during intense physical stress. This causes difficulty when trying to fight off germs and viruses. Studies have found preventing inflammation and injury requires prioritizing rest. Constantly being on the go and under intense physical stress can take a toll not only on the body but the brain as well. This can lead to irritability, frustration, anger, which leads to other health problems generating a vicious cycle.

Now in the heart of the school year � new shoes, haircuts, homework, and their bulging backpacks. Think about the backpack your child is carrying. Sure, they load them up with books, but did you know that wearing a heavy backpack for a long time can actually hurt your child? The American Academy of Pediatrics (AAP) has provided some helpful guidelines for choosing a backpack for your child and avoiding the injury that can result from one that is too heavy.
What are the health risks of a heavy backpack?
Wearing a heavy backpack can strain the shoulders, back, and neck. As the child�s body tries to compensate for the extra weight, such as leaning forward, it can adopt positions that put the spine out of alignment. It can also cause the muscles to fatigue and weaken. This results in poor posture and a misaligned spine.
The longer he or she carries the extra weight, the worse it gets. Over time, the child can experience pain, stiffness, and problems with flexibility and range of motion. This can significantly increase the child�s potential for injury. The effects may include backache, sore or stiff neck, sore shoulders, and headaches.
How heavy is too heavy for a child�s backpack?
According to the AAP, a child�s backpack should weigh less than 10 to 20 percent of his or her body weight � and no more. However, a Consumer Reports survey showed that the lower end of the range, around 10 percent or less, is preferable. In short, the lighter the backpack, the healthier it is for your child. A good rule of thumb is to observe your child wearing the backpack. If they are stooped or leaning forward, it is too heavy.
Children who are shorter, as well as girls, may be more prone to back pain caused by carrying heavy backpacks. This means that for these children you need to aim for even lighter weights. Children who are overweight may also be at risk for injury. The excess weight already puts a strain on their joints and muscles; the heavy backpack exacerbates the situation.
Children who wear their backpack over one shoulder also increase their risk of injury. This puts all the weight on one side, causing the child to bend or lean in an effort to compensate for the off-kilter weight. This can strain the shoulder and back, eventually causing injury and pain.
Helping your child avoid carrying a heavy backpack.
If you notice that your child cannot stand up straight while wearing the backpack, then it is too heavy. You should inspect your child�s backpack on a regular basis to test the heaviness. When purchasing a backpack, aim for wide, padded straps that are adjustable. It should fit the child well and to be too big. The straps should not be too loose. You want it to fit close to your child�s body and should come to just below the waist � but not too far. Don�t allow your child to carry the backpack on one shoulder, encourage them to wear it on both shoulders. This distributes the weight more evenly.
If your child is carrying a heavy backpack, you may need to talk to their teacher to see what is necessary for him or her to carry daily, and what can be left at home or at school. Work together to find ways to lighten the load and avoid injury. Also, keep in mind, your child may not bring your attention to the fact that their backpack is too heavy. It is up to you to observe and intervene for them.
