Final answer:
Proper hydration during steady state aerobic exercise is associated with lower perceived exertion, lower heart rate, and lower core temperature, enhancing overall exercise performance and comfort. The correct answer is c. all of these.
Step-by-step explanation:
During steady state aerobic exercise, adequate hydration is associated with several physiological benefits that help maintain optimal performance and comfort levels.
- (a) Lower perceived exertion: When adequately hydrated, individuals may feel that the exercise is less strenuous.
- (b) Lower heart rate: Hydration can contribute to a more controlled heart rate during exercise.
- (c) Lower core temperature: Proper hydration helps to regulate core temperature, making heat dissipation more efficient through mechanisms like sweating and respiration.
- (d) All of the above: Each of these factors - lower perceived exertion, lower heart rate, and lower core temperature - are impacted positively by adequate hydration during exercise.
Therefore, the correct answer is c. all of these, as each mentioned response is a benefit associated with proper hydration during exercise.
