Chapter 11.6, Problem 24BYGO

Discuss four key safety factors and hazards in oxygen administration

State whether HR increased or decreased after exercise.

Compare the effects of hypocalcemia on skeletalmuscle and cardiac muscle.

Discuss the physiological rationale for the assessment of the lactate threshold in the endurance athlete.

Define the Bohr effect and describe how it explains maximal oxygen delivery to tissues in greatest need.

Explain the physiological mechanisms involved in increased respiratory rate during exercise (400 words)

Compare and contrast the hyperpnea of exercise with hyperventilation.

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?

Is a good VO2 max important for anaerobic athletes?
