Exercising harder increases capacity, while working out longer increases endurance. References. Brian Mac: Muscle Training.
How does adenosine triphosphate help muscles?
A chemical called adenosine triphosphate helps make muscle contractions. After a few repetitions, you deplete the stores of ATP in your muscles and must create more. Initially, you burn glycogen to replace these stores. The longer you work, the more fat you burn. During short, high-intensity exercise, such as sprint training or a tennis match, your body use mostly glycogen. If you exercise for long periods without a break, such as when you jog or use a cardio machine, your muscles burn more fat. When you exercise, your body produces lactic acid, which inhibits muscle contractions. The longer you take between a point or play, the more lactic acid leaves your muscle -- but not all of it. The longer you exercise, the more lactic acid you have in your muscles, which can eventually lead to cramping and muscle fatigue.
What is the contraction of the muscles during exercise?
Contractions. Muscles contract during exercise, creating eccentric, eccentric or isometric contractions to perform work. When you raise a dumbbell during a biceps curl, your muscles contract, creating a concentric contraction. When you lower the weight, your muscles lengthen, creating an eccentric contraction.
What happens when you exercise without a break?
If you exercise for long periods without a break, such as when you jog or use a cardio machine, your muscles burn more fat. When you exercise, your body produces lactic acid, which inhibits muscle contractions. The longer you take between a point or play, the more lactic acid leaves your muscle -- but not all of it.
What is the purpose of muscle fibers?
