Answer: increase

Answer: hypertrophy (hyperplasia/hypertrophy)

Flashcard 3: The mean systemic filling pressure _____ tremendously at the onset of heavy exercise.

Answer: rises

Flashcard 4: Signals from _____ play a role in stimulating the respiratory drive during exercise.

Answer: joint proprioceptors

Flashcard 5: The increase in heart rate and ventilation at the onset of exercise is an example of a _____ control mechanism.

Answer: Feedforward

Extra: Feedforward (anticipatory) control allows the body to prepare for exercise before feedback from chemoreceptors or mechanoreceptors is even received. This is mediated by 'central command' from the motor cortex.

Flashcard 6: The exercise-induced hyperventilation during vigorous exercise is produced due to the receptors present in _____.

Answer: carotid bodies

Flashcard 7: McArdle index is the _____ rate

Answer: sweat

Extra: McArdle's Index is also known as the **Predicted 4-hour Sweat Rate (P4SR)**. It is an index used to assess environmental heat stress.
