Oxygen
Athletes eat bananas before strenuous activity because they are a good source of carbohydrates for energy, potassium to prevent muscle cramps, and easily digestible for quick absorption. This fruit can help fuel their performance and support muscle function during exercise.
Yes. Strenuous exercise can kill the muscle fibers. Such muscle fibers are replaced by fibrous tissue.
Ellipticals work by exercising both your heart with intense cardio-vascular activity, paired with muscle-strengthening of the calves and thighs. It is a strenuous and vigorous activity.
A type of muscle paralization during REM periods.
well yes and no. science has proved that muscles are built through rest and restoration, but if you did no strenuous activity that day or recently muscle will not just build on its own.
Ability to repeatedly continue the work without muscle fatigue. the ability to sustain activity for longer periods of time.
During strenuous muscular activity, the heart rate, breathing rate, and blood flow to muscles increase to deliver more oxygen and nutrients needed for energy production. Additionally, the production of lactic acid and heat also increase as byproducts of energy metabolism.
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.
to decrease the NADH and increase the NAD+
The breakdown of adenosine triphosphate (ATP) molecules in muscle cells releases energy that powers muscle contractions. During strenuous exercise, the breakdown of ATP provides immediate energy for muscle activity.
This practice is to mainly avoid muscle cramping that can occur when strenuous activity is immediately followed by rest. Most professionals refer to this as "cooling down".
