Q

What is the difference between interval and repetition training?

A

Repetition training usually involves shorter more higher intensity intervals, lasting 30-90 seconds and focuses on increasing anaerobic power vs. aerobic power/endurance

Maintain strength and endurance in adjacent, non-affected muscles

17
Q

Resistance training with high volume and brief rest periods will most heavily affect which hormone: Cortisol, testosterone, or growth hormone?

A

Human growth hormone

18
Q

How many pyruvate molecules result from anaerobic glycolysis?

A

2

1 glucose –> 2 Pyruvate –> Acetyl Coenzyme A –> Krebs cycle

21
Q

What are the 3 primary functions of hemoglobin?

A

22
Q

Which action is the pulmonary division of the arterial system responsible for?

A

23
Q

Which action is the systemic division of the arterial system responsible for?

A

Pumps oxygenated blood from the heart to the tissues and returns deoxygenated blood from tissues back to the heart
