問 2
1 点In conditions of extreme heat, a marathon runner experiences cardiovascular drift. Which statement best explains the mechanism and resulting effect on the cardiovascular system during this phenomenon?
問 3
1 点During prolonged exercise in the heat, the body must balance metabolic demand with thermoregulation. Evaluate the impact of peripheral vasodilation on the cardiovascular system during this process.
問 4
1 点Which of the following describes the most significant chronic adaptation to exercise in the heat that aids in maintaining a lower core temperature during performance?
問 5
1 点Analyze the oxyhaemoglobin dissociation curve in the context of an athlete exercising in high heat. What is the effect of the temperature increase on oxygen delivery at the muscles?
問 6
3 点Outline why cardiovascular drift is more pronounced when exercising in the heat compared to a temperate environment.

問 9
5 点Elite marathon runners often struggle with cardiovascular drift when competing in high-ambient temperatures.
(a) Define the term cardiovascular drift and describe the physiological process that leads to its occurrence during prolonged exercise in the heat.
(b) Explain how the redistribution of cardiac output to the skin for temperature regulation impacts stroke volume and heart rate to maintain cardiac output.

問 10
6 点During a triathlon held in 35°C heat, an athlete experiences a significant rise in core body temperature.
(a) Describe the role of the vasomotor centre and pre-capillary sphincters in the redistribution of cardiac output during exercise in these conditions.
(b) Explain the potential respiratory and cardiovascular risks associated with exercising in extreme heat if the body fails to maintain homeostasis through temperature regulation.
