Muscle grows larger from exercise because more muscle filaments are created within each cell. There are thick myosin filatments and thin actin filaments which form cross bridges with each other. The heads of the thick filaments undergo a power stroke in which they bind to the thin filaments and the head bends down, pulling the thick filament across the thin filament, shortening the muscle and creating tension.
Think of a pulling a car with a rope. you are the thick filament, the rope is the thin filament. You grab the rope and pull, and then move your hands down the rope and do it again, this is like the power stroke. Now, add more people and more ropes, you can pull a much heavier load. That is how the muscle gets stronger.
work out exercise ,..is an exercise that helps our muscles become stronger and bigger..
No, muscles do not get smaller after a workout. In fact, they typically get bigger and stronger as a result of the exercise.
If astronauts don't exercise in space, weightlessness eventually causes there muscles to shrink?
contacting and retracting. actually they are also breaking slightly when you exercise, that way, when they heal the heal bigger and better. (hence, bigger muscles)
because our muscle is important to excercise to grow bigger
no no
No exercise causes your muscles to weaken and can cause weight gain and tiredness
Your muscles cramp up after exercise if you do not stretch
Because exercise works Ur muscles which causes the fat cells to shrink! :)
lactate
Usually not unless it develops muscles but i think the cat will probably get smaller.
It depends how much muscles they have.The more you exercise the bigger your muscles grow,therefore you get stronger.
