5.2.1.1 Short Term Effects of Exercise on Muscular System

Increased blood supply

As an effect of involvement in exercise our metabolic rate (rate of energy
produced and released by the muscles) also increases gradually. Blood does
not only work as to import oxygen but also to remove waste products like
carbon dioxide.

Increased muscle temperature
Effect of short term activity includes rise of the temperature of the body
that happens because of chemical break down of fats and carbohydrates.
Increase muscle flexibility

Due to increase in temperature during the activity muscles become more
flexible, it means greater range of motion and possibilities of injuries are
also reduced.
