A buildup in lactic acid is the culprit. This buildup only occurs when anaerobic exercise, such as sprinting and weight lifting, is performed.
During exercise muscle cells use oxygen.
Exercise causes your muscle cells to widen and grow so that that muscle becomes bigger and stronger.
The pectoralis major muscle is primarily targeted during a bench press exercise.
Exercise causes the muscle to break apart. When your body repairs this damage, new muscle tissue is made. This causes the muscle to grow over time
You will see muscle development after exercise, not during.
Yes. Strenuous exercise can kill the muscle fibers. Such muscle fibers are replaced by fibrous tissue.
Your muscles cramp up after exercise if you do not stretch
Hypertrophy.
Muscle contraction and relaxation require salts which are lost through sweat during vigorous exercise. This causes some muscles particularly low in these materials to contract uncontrollably, creating a cramp.
Warming up (light exercise before more strenuous exercise) results in vasodilation of the skeletal circulation. This causes increased blood supply to the skeletal muscle to satisfy the oxygen and nutrient demands of the increased metabolic activity of the muscle during exercise.
The phenomenon known as muscle pump is caused by increased blood flow to the muscles during exercise, which helps deliver oxygen and nutrients while removing waste products.
Lactic acid is the product of anaerobic respiration that causes muscle burning or soreness during intense exercise. This occurs when the body cannot supply enough oxygen to the muscles, leading to the buildup of lactic acid as a byproduct.
