How long does energy from the Phosphagen system diminish?

That is, the ATP and PC activity combined, referred to as the phosphagen system, can provide energy for less than 10 seconds of maximal activity.

How often does the American College of Sports Medicine recommended exercise for cardiorespiratory fitness quizlet?

According to the American College of Sports Medicine the recommended frequency for cardiorespiratory exercise is: 3 to 5 days per week.

What percentage of body weight must be lost due to dehydration quizlet?

List the symptoms of dehydration associated 3-4% loss of body weight, 3-4%: impaired physical functioning, dry mouth, reduction in urine, flushed skin, impatience and apathy.

Which use of protein for exercise is accurately described?

Which use of protein for exercise is accurately described? It repairs muscle tissue after exercise.

Which of the following is an effect of exercise on protein metabolism?

Exercise has a profound acute effect on protein metabolism. Whereas reports on whole body responses to exercise have varied results, it is generally agreed leucine oxidation is increased during exercise, thus indicating increased net protein breakdown.

Which of the following represents current knowledge of the role of vitamin and mineral supplements in physical performance quizlet?

Which of the following represents current knowledge of the role of vitamin and mineral supplements in physical performance? They may be beneficial for athletes who struggle to meet their energy requirements.

Which of the following is a feature of the body’s response to engaging in physical activity?

Which of the following is a feature of the body’s response to the engaging in physical activity? After an intense and vigorous workout, metabolism, remains elevated for several hours. What is the predominant fuel used by muscle cells during low or moderate intensity activity?

What is the end product of anaerobic metabolism?

The end products of anaerobic respiration are Lactic acid or ethanol and ATP molecules. Anaerobic respiration takes place in the absence of oxygen and is seen in lower animals.

What is a common product of anaerobic exercise?

During heavy exercise, the total work exceeds the capacity for aerobic work, which is limited by oxygen transport (see later). The difference is made up by anaerobic metabolism, of which the principal product is lactic acid (seeFig.

What are the products of anaerobic respiration?

Anaerobic respiration occurs in the absence of oxygen and is less efficient than aerobic respiration. Unlike aerobic respiration, the end products here are ethyl alcohol as in yeasts and lactic acid as in animal cells. So the answer is ‘Alcohol and lactic acid’.

What is the product of anaerobic glucose metabolism?

Carbohydrate Metabolism Lactate formed during anaerobic glycolysis enters the gluconeogenic pathway after oxidation to pyruvate by lactate dehydrogenase. After intense exercise, the lactate produced diffuses from the muscle into the blood and is taken up by the liver to be converted into glucose and glycogen

How do you determine the fluid requirement during exercise?

If water is consumed during exercise subtract the water weight from the post exercise weight. Every 2.2 pounds a person loses equates to 1 liter of fluid loss (sweat loss). For example, if someone loses 5 pounds in 1 hour their sweat rate is 5/2.2 x3d 2.27 liters/hour.

How much fluid is lost during exercise?

How much do you need to replace your sweat losses? pound (16oz, or . 5kg) you lose, drink 80 to 100 percent of that loss (13 to 16oz or 400 to 480ml) while exercising to stay in optimal fluid balance.

How do you lose water during exercise?

You can lose a lot of fluid when you exercise u2013 as much as a litre or two an hour u2013 mainly through sweating and breathing. So, you’ll need to drink more when you exercise. If you don’t top this fluid back up, you can get dehydrated. This can affect both your general health and how well you can exercise.

How is fluid loss impacted by the intensity of the activity?

During exercise the body cools itself by sweating but this ultimately results in a loss of body fluid which, if not replaced, can lead to dehydration. Sweat production (fluid loss) increases with increasing temperature and humidity, as well as with an increase in exercise intensity
