Besides blood glucose level and blood oxygen level, what other body conditions are also disrupted by your exercise? Name at least two.
Shown below are changes that occur in skeletal muscle during vigorous physical activity. For each parameter, indicate its effect on percent HbO2 saturation (↑,↓) and the amount of free O2 available to the muscle fibers (↑,↓).
↓ Po2 = increase / decrease HbO2 saturation, increase / decrease free O2
↓ pH = increase / decrease HbO2 saturation, increase / decrease free O2
↑ Pco2 = increase / decrease HbO2 saturation, increase / decrease free O2
↑ 2,3-BPG = increase / decrease HbO2 saturation, increase / decrease free O2
↑ Temperature = increase / decrease HbO2 saturation, increase / decrease free O2
Discuss the adaptations that occur after heat acclimation. Why do these support us during exercise in the heat?

- Endurance athletes sometimes follow the exercise-and-diet plan described here: 7 days before an event, do exhaustive exercises so as to all but deplete glycogen stores. For the next 2 to 3 days, consume few carbohydrates and do moderate- to low- intensity exercises. Finally, 3 to 4 days before the event, consume a diet rich in carbohydrates. Explain the benefits of this regime.arrow_forwardWhich of the following nutrients is most helpful for promoting endurance during sustained activity? Question 39 options: a) Carbohydrate b) Protein c) Water d) Fatarrow_forwardIf an individual is exercising at a low intensity for several hours, how would the concentrations of substrates change in plasma? Plasma levels of free fatty acids would increase as triglycerides are broken down for sustained energy. They remain stable and unaffected by exercise. Plasma glucose levels would gradually increase the longer exercise continues. Plasma levels of amino acids would increase, as protein breakdown would be needed to fuel continued exercisearrow_forward
- The oxygen consumed after strenuous exercise stops is significantly greater than the oxygen deficit and is termed excess postexercise oxygen consumption (EPOC). Why is so much more oxygen required after intense exercise?arrow_forwardOxidation of ingested CHO during exercise depends on each of the following variables except... Group of answer choices CHO flavor. ingested amount. exercise intensity. type of CHO.arrow_forwardWhat is the main source during aerobic exercises? What is the benefit of aerobic respiration in the body? What is the benefit of anaerobic respiration in the body? How often does an individual should undergo aerobic and anaerobic exercises?arrow_forward
- How effective is aerobic exercise as a way to manage stress and improvewell-being?arrow_forwardGlycogen depletion resulting from intense, extensive exercise can lead to exhaustion and the inability to continue exercising. Some people also experience dizziness, an inability to concentrate, and a loss of muscle control. Account for these symptoms.arrow_forwardOn the diagram below, the fat burning zone is at a fairly low exercise intensity. Describe why the body would burn more fat in the "fat burning zone" compared to "hardcore training" or "maximum effort".arrow_forward
- Muscle hypertrophy training is catalyzed by which of the following? Mechanical tension, high reps, great pump Heavy weight, muscle damage, resistance bands Heavy weight, metabolic stress, post-workout carbs Mechanical tension, muscle damage, metabolic stressarrow_forwardResistance (weight) training is recommended as part of an exercise program to lose weight and maintain that weight loss.
