After light exercise, the oxygen consumed in recovery is approximately equal to the oxygen deficit, which is the amount of additional oxygen that would have been consumed had oxygen consumption reached steady state immediately. How is the oxygen consumed in recovery used?

Which of the following statements does NOT apply to the K value in the equation for the oxygen binding curve of myoglobin? It is numerically equal to p50. O A. It is defined as that oxygen partial pressure at which half of the oxygen binding sites are occupied. В. If Y> K, then myoglobin is less than 50% saturated with oxygen. OC. O D. It is a measure of the affinity of myoglobin for oxygen. OE. It is the value of po2 at which Y = 0.5.

In order to improve their recovery after an intense work out or competition, many high-level athletes use "cool downs" to rapidly slow down their movements, by eating a snack, and breathing deeply. What choice below accurately explains how these steps aid cellular respiration? A. Eating a snack takes in more energy which converts to sugar needed by the body to produce oxygen to begin cellular respiration. B. Cooling down in this way they are able to take in oxygen and sugar, which allows their cells to produce energy through cellular respiration. C. Breathing deeply and eating a snack releases more carbon dioxide and sugar, which leads to more energy for cellular respiration to begin. D. Cooling down in this way they are able to take in carbon dioxide and water which allows their cells to produce energy through cellular respiration. 5.

Explain in detail why fast-twitch fibers will use anaerobic respiration rather than aerobic respiration even though aerobic respiration is about 20 times more efficient in terms of ATP produced per each glucose molecule?

Describe the changes in barometric pressure, PO2, and air density with increasing altitude. Include an explanation of why maximal aerobic power decreases at altitude and what effect this has on performance in long-distance races. What recommendations would you have for a long-distance runner about training at altitude? What benefits and limitations are associated with altitude training? How would you recommend the athlete work around the limitations?
