Q & A

What is muscle hypertrophy and how is it activated during exercise?

Muscle hypertrophy is the growth and increase in size of muscle cells, which is activated when the resistance during exercise exceeds what the body can handle. This process leads to more blood being driven to the muscles to provide additional oxygen, and if the demand for oxygen exceeds supply, lactic acid forms but is typically flushed out within half an hour to an hour after exercising.

Why does lactic acid form in the body during exercise and how is it usually dealt with?

Lactic acid forms in the body when there is not enough supplemental oxygen during exercise. It is flushed out of the body within half an hour to an hour after working out, which is a normal process.

How does exercise affect the heart and what are the benefits for cardiovascular fitness?

Exercise increases heart rate as the body works harder than normal. The increase in heart rate depends on fitness level and type of exercise. Regular exercise helps the heart get used to high-level performance, which can minimize resting heart rate and improve heart rate recovery after exercise.

How does the lung function during exercise and what happens to the breathing rate?

During exercise, the lungs work to provide energy, oxygen, and eliminate carbon dioxide. As the body works harder, the demand for oxygen increases, leading to an increase in breathing rate from about 10 to 15 times a minute. This helps circulate oxygen to the muscles to support continuous movement.

What role does the skin play during exercise and how can it benefit from increased blood flow?

Increased blood flow during exercise helps maintain skin cells by providing nutrients and oxygen. It can improve wrinkles, acne, and even reverse skin aging. Additionally, blood flow aids in washing away waste products, cleansing the body from the inside, and can help flush out toxins through sweating.

How does exercise impact hair growth and what are some beneficial activities for hair health?

Sweating during exercise flushes out toxins and waste, including from the scalp, which can unclog hair follicles and promote healthy hair growth. Moderate to high-level cardio activities like cycling, dance, running, yoga, and Zumba are beneficial for hair health, as are inversion yoga poses that increase blood flow to the scalp.

What is the liver's role during exercise and how can it be positively affected by physical activity?

The liver, located in the upper right side of the abdomen, can be burdened by excess weight. Exercise reduces total body fat, including liver fat, decreasing elevated liver enzymes. Workouts can shape the liver by enhancing its circulatory ability, making it more resilient against tissue degeneration.

How does exercise affect the joints and what is the role of cartilage in this process?

Physical activity can put additional weight on joints, but it also keeps the tissues around the joints healthy, reducing pressure and protecting them. Cartilage, the cushioning tissue around joints, can degenerate over time, but exercise helps maintain its health, providing stability and smooth motion.

How does exercise impact brain function and what are the psychological benefits?

Exercise improves brain growth by increasing blood flow to the brain, promoting memory strength, and increasing the production of dopamine and serotonin, which are feel-good chemicals. It can help lift mood, ease depression and anxiety, and improve the brain's executive functions for better organization and focus.

What are the benefits of exercise for back problems and how does it help maintain spinal health?

Exercise is a natural solution for back problems caused by poor posture or minimal movement. It helps repair and nourish spinal structures, keeps the back flexible and strong, and reduces the risk of injuries. Regular exercise allows the discs in the back to interchange fluids, providing nutrition and reducing swelling in injured tissues.

How does exercise affect the immune system and what are the health benefits?

Exercise keeps the lymph system in good condition, helping to remove metabolic waste through the contraction of muscles during physical activity. It also produces more white blood cells, which can reduce the presence of bacteria and viruses, and boost the immune system's ability to identify and destroy harmful invaders.

What is the impact of exercise on waistline and body fat, and how does it help with weight management?

Exercise helps reduce subcutaneous and visceral fat, improving overall looks and vitality. It increases the production of mitochondria and proteins that aid in the transportation of fatty acids into cells for energy conversion, creating enzymes that break down fat more efficiently.

How does exercise influence hormone levels and what are the specific benefits for men and women?

Regular exercise can improve hormone levels. For men, it can increase testosterone levels, which aids in bone and muscle growth and sex drive. For women, it can regulate estrogen production, helping with fertility, weight regulation, and reducing menopausal symptoms. Exercise also releases the hormone irisin, which may contribute to longer telomeres and reduced risk of age-related diseases.

What Happens To Your Body During Exercise?

12.

Muscles- According to Livestrong.com, your muscles form some of the integral tissues

in your body, and tissue changes occur with resistance exercise.

Any form of exercise which includes lifting weights, jogging or doing pushups is some

kind of resistance activity being placed on your muscles.

When the resistance is greater than what your body can handle, muscle building or muscle

hypertrophy is activated.

So more blood is driven to the muscles being exercised to give additional oxygen.

Without the supplemental oxygen, lactic acid will form in the body instead.

But it is usually flushed out of the body within half an hour to an hour after working

out.

Tiny tears build in the muscle which helps them become active and bigger as the heal.

This is perfectly normal.

The greater the tear, the more you’ll be sore after exercising.

This typically only lasts a few days as soreness means there are changes in your muscles.

11.

Heart- As with any workout, your heart rate increases because you’re working much harder

than you normally are.

How much your rate will go up depends on how fit you are and the type of exercise you’re

doing.

Training experts vary on how high your heart rate should be when working out, but it does

need to be significantly higher than your resting heart rate to enhance your cardiovascular

fitness.

As you begin your workout, your skeletal muscles compress the veins near them which push the

blood towards your heart.

They contract and relax, driving extra blood to your heart which causes your heart rate

to go up.

Within this process, it means you’re putting more labor on your arm and leg muscles which

pump more blood to your heart.

So when working out your heart will get used to high-level performance, and these changes

will minimize your resting heart rate and boost your heart rate recovery after you exercise.

10.

Lungs- During your workout, aside from your heart, another vital organ comes in action:

the lungs.

Your lungs provide energy, oxygen and eliminate carbon dioxide which is created when producing

energy.

When you have healthy lungs, you keep maintaining a large breathing reserve.

You may feel out of breath after intense activity, but you will not be out of breath.

When your muscles and your body start to work harder, you will use more oxygen and make

more carbon dioxide.

To bear with the extra demand, you will start to increase your breathing from about 10 to

15 times a minute.

Your circulation will also increase to force oxygen to your muscles so they can keep moving.

When your lung function is cut short, you use a larger part of your breathing reserve

which can feel uncomfortable as you try to catch your breath.

This is entirely normal, and this type of training helps with circulation.

Regular exercise activity can improve the function and strength of your lungs, making

it more efficient.

9.

Skin- When you exercise your increasing blood flow which helps maintain skin cells and keep

them nourished.

Your blood transports nutrients and oxygen to the cells working throughout your entire

body including the skin.

In addition, it improves wrinkles and acne and can even reverse skin aging.

Also blood flow aids in washing away any waste products which flushes cellular debris from

your body.

Think of it as cleansing your body but from the inside.

Sweating can help drive draw out the toxins in your body, but don’t assume this is a

quick fix to vanish pimples.

Exercise then shower afterward.

Working out also helps to flush out your pores.

With aerobic exercise, oxygenated blood circulates throughout your entire body will cause you

to glow because your blood vessels fill up closer to the surface.

After an intense workout, your vessels dilate which gives your skin a vibrant and healthy

look.

Not only doing exercise boost your collagen but it’ll help keep your skin firm, elastic

and supple.

8.

Hair- Sweating through exercise flushed out toxins and waste from our body and when we

sweat from our scalp, it aids to unclog the hair follicles.

This allows enough space for new hair to grow.

This also gives nourishment to hair roots which promote healthy hair growth.

In fact, exercising and its effects have been compared to the results of an oil massage

since both increase blood circulation and can relax you.

Moderate to high-level cardio activity like cycling, dance, running, yoga, Zumba is beneficial

for healthy hair.

While inversion yoga poses like shoulder stands, downward facing dog, sun salutation and headstands

are excellent for healthy hair growth.

These inversion positions increase blood flow to your scalp and fix hormonal imbalances

which contribute to hair loss.

7.

Liver- Located right below your diaphragm, centered in the upper right side of your abdomen

is your liver which lies under your ribs.

When you're overweight, this puts a burden on your liver.

So by exercising your total body fat is cut down and the fat content in your liver is

also reduced as well which decreases reduction of elevated liver enzymes.

When you exercise, the workouts you do shapes the liver by boosting its capability to drain

and fill at its maximum capacity.

Through maximizing it circulatory ability, your liver is better able to withstand liver

tissue degeneration.

A few simple moves to enhance your liver’s health is trunk turning.

Start off by sitting upright with your legs crossed with overlying palms over your lower

stomach.

Turn your turn to the left and right about fifteen times.

Then turn from side to side in a gentle motion.

Then in a centered pose, join your hands and fingers and interlock.

Then push your palms forward about eight times.

6.

Joints- Physical activity puts additional weight on the joints, sometimes even up to

five or six times more than your average body weight.

Your ankles, elbows, hips, knees, and shoulders all have different roles but works in similar

ways.

Each joint in your body is surrounded with cushioning tissue called cartilage and the

ends of your bones.

The lubricating fluid and soft tissue help to provide easy and smooth motion movements,

while your ligaments and tendons supply stability.

The cushioning around your joints can begin to degenerate or wear down over time.

This is common in people with osteoarthritis so by exercising the tissues become healthy

and serve as a brace to protect your joints and lessen the pressure.

Nutrients circulate to the joint since physical activity pushes water molecules out of the

cartilage just like a sponge.

In addition, cellular waste is eliminated where damaged cells in are broken down and

destroyed.

5.

Brain- As we age, the formation of new brain cells slow down, and our brain tissue also

shrinks.

So by exercising, it helps improve brain growth by driving blood flow to the brain.

It also promotes memory strength and heightens the body’s production of dopamine and serotonin

which are feel good chemicals.

Exercise can help lift up your mood and can help ease depression and anxiety.

Working out also improves the brain’s executive functions which allow us to organize better

and focus more on complex tasks.

Since brain cells are depleted during times of high stress, physical activity lowers cortisol

levels.

It is also thought that exercise helps promote new nerve cells in the hippocampus which is

connected to producing new memories.

This helps eliminate scattered, slow thinking and forgetfulness.

When you work out regularly, exercise triggers the release of neurotransmitter, which causes

you to have “runners high” due to endorphins.

The pituitary gland alerts the adrenal gland in the brain to pump out these hormones needed

for movement.

4.

Back- For most back problems caused by poor posture or minimal movement, exercise and

physical activity are natural solutions.

Progressive, gradual and controlled exercise rather than bed rest is actually the best

long-term fix for reducing back pain.

When you exercise, you are repairing and nourishing spinal structures, which can help aid existing

back problems.Exercise and movement keep your back flexible and strong and reduces the risk

of injuries and back pain.

When you participate in fitness activities, you’re keeping your back healthy by allowing

the discs to interchange fluids.

This is how the disc gets its nutrition.

An good disc will fill with water and squeeze it out, and fluid trade reduces the swelling

in other tissues that naturally happens surrounding injured discs.

When there is no exercise involved, the enlargement increases and the disc get degenerated and

malnourished.

So working out, stretches, repairs and strengthens the muscles supporting your back.

3.

Immune System- Working out keeps the lymph system in good condition.

Your body typically has 500 lymph nodes which are tissues that get rid of metabolic waste.

But this waste can’t be removed without the help of nearby muscles.

So when your muscles contract during exercise, it puts pressure on lymph nodes that pump

out the waste from your body.

Working out also produces white cells in the body and with more white blood cells, means

fewer bacteria and viruses.

In fact, Ph.D. director David Nieman of the human performance labs of Appalachian State

University states that just forty-five minutes of walking every day can reduce the number

of workdays you miss due to sickness up to fifty percent.

Exercise is a natural stimulus that is proven to boost your immune system’s capability

to identify and destroy toxins and harmful invaders.

2.

Waistline- Worried about you love handles?

Don’t worry, exercise can make them disappear, but did you know it’s the loss of excess

fat buried inside your body that helps your overall looks and vitality?

Your body contains two different types of fat.

Subcutaneous fat which is the one you can pinch and visceral fat that coats the abdominal

organs.

Regular physical activity trains your body to burn visceral fat more efficiently.

When you workout, your body produces more mitochondria, where the aerobic metabolism

happens.

It makes more proteins to boost the transportation of fatty acids into cells that can be converted

into energy.

This process creates more enzymes that destroy fat.

The more enzymes you have, the faster the visceral fat can be broken down, and the better

you’ll look.

1.

Hormones- Never underestimate the power of a good sweat.

Regular physical exercise can help improve your weight and boost hormone levels.

For men, testosterone, which is the hormone that builds bone and muscle growth and increases

sex drive rise for fifteen minutes to an hour after exercising.

But this varies on your fitness level, age and how intensely you worked out.

Testosterone circulates in the body to create muscle mass.

For women, working out can have an impact on estrogen production.

Exercising even in small amounts can regulate body weight for healthy levels of fertility

and can even help women to sleep better and reduce hot flashes in postmenopausal women.

The exercise hormone called irisin also breaks off and circulates throughout your entire

body.

A U.K. investigation found that people with more higher levels of irisin in their bodies

were more likely to have longer caps at the end of chromosomes that shorten as you get

older.

This can decrease the risk of Alzheimer's, cancer and heart disease.
