What Happens To Your Body During Exercise!

Summary

This video explains the various effects exercise has on your body, highlighting the benefits to muscles, heart, lungs, skin, hair, liver, joints, brain, back, immune system, waistline, and hormones. Exercise leads to muscle growth, enhanced cardiovascular and lung function, improved skin and hair health, and better liver and joint conditions. It also boosts brain function, back strength, immune response, fat loss, and hormone levels, contributing to overall well-being and vitality.

Takeaways

• 💪 Exercise stimulates muscle hypertrophy, leading to increased blood flow and oxygen supply, which helps in muscle repair and growth.
• 🏃‍♂️ Resistance activities, such as weight lifting and jogging, can cause muscle soreness due to micro-tears that heal and strengthen over a few days.
• 🚀 An elevated heart rate during exercise is crucial for enhancing cardiovascular fitness and is influenced by fitness level and exercise type.
• 💓 The heart's ability to pump blood increases during workouts, improving its performance and leading to a lower resting heart rate over time.
• 🌬️ Lungs play a vital role in supplying oxygen and removing carbon dioxide during exercise, with breathing rates increasing to meet the body's demands.
• 🧖‍♀️ Regular exercise improves skin health by increasing blood flow, aiding in nutrient delivery and waste removal, and potentially reversing signs of aging.
• 💧 Sweating during exercise helps to unclog hair follicles, promoting healthy hair growth and providing nourishment to hair roots.
• 🏋️‍♀️ Liver health is improved by reducing body fat through exercise, which also enhances the liver's capacity to function effectively.
• 🦴 Physical activity is beneficial for joint health, as it helps to maintain cartilage and reduce pressure on joints, especially in those with osteoarthritis.
• 🧠 Exercise promotes brain health by increasing blood flow, improving memory, and reducing stress levels, which can help combat depression and anxiety.
• 🌀 The lymphatic system benefits from exercise, as muscle contractions aid in the removal of metabolic waste and boost the immune system's ability to fight off infections.

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.
