Neuromuscular Adaptations to Training — Flashcards

Flashcard 1: Slow twitch muscle fibers perform more _____ due to increased mitochondria

Answer: oxidative phosphorylation

Flashcard 2: Increase in muscle blood flow is more in iso_____ exercise than isometric exercise

Answer: tonic

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

Answer: rises

Flashcard 4: The stimulus for increased ventilation rate is the activation of _____ at the beginning of the exercise.

Answer: joint proprioceptors (receptors)

Flashcard 5: Increase in alveolar ventilation occurs during exercise due to additional signals from _____ and joint proprioceptors

Answer: contracting muscles

Flashcard 6: Exercise adaptation at high altitudes:To make up for the respiratory alkalosis, kidneys _____ hydrogen ion secretion and increase bicarbonate excretion.

Answer: reduce

Flashcard 7: Blood flow _____ to the kidneys, liver, and GIT during exercise.

Answer: decreases

Extra: During exercise, blood flow to the kidneys, liver, and gastrointestinal tract (GIT) decreases due to sympathetic-mediated vasoconstriction. In contrast, blood flow to active skeletal muscles increases significantly due to local metabolic factors (autoregulation).

Flashcard 8: 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.

Flashcard 9: f19bbc4344d44f18b5dc20ff1137c063-ao-

Answer: kcal energy requirements per day

Extra: 

Flashcard 10: There is a sharp _____ in the diastolic blood pressure in isometric exercise.

Answer: rise
