What else can I help you with?
What do muscle cells run low on during periods of strenuouse activity?
Oxygen
Why do athletes eat bananas before a strenuous activity?
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.
During strenuous activity lack of which substance limits ATP available for muscle contraction?
During strenuous activity, a lack of oxygen limits the availability of ATP for muscle contraction. Oxygen is crucial for aerobic respiration, which produces ATP efficiently in the presence of sufficient oxygen. When oxygen levels are low, the body relies on anaerobic metabolism, which generates ATP less efficiently and leads to the accumulation of lactic acid, causing fatigue. Thus, adequate oxygen supply is essential for sustained muscle performance.
Does muscle fibers brake down during exercise?
Yes. Strenuous exercise can kill the muscle fibers. Such muscle fibers are replaced by fibrous tissue.
How do ellipticals work?
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.
What is muscle atonia?
A type of muscle paralization during REM periods.
Does muscle build when you sleep?
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.
What is muscle endurence?
Ability to repeatedly continue the work without muscle fatigue. the ability to sustain activity for longer periods of time.
What increases during strenuous muscular activity?
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.
What are physiological factors that are results of warming up?
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.
When a muscle becomes anaerobic during strenuous exercise why is it necessary to convert pyruvate to lactic acid?
to decrease the NADH and increase the NAD+
What reaction provides energy to power muscles?
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.
