High levels of a molecule called Nitric oxide

/in /by

Some athletes have drink beet juice (yes, juice from beets) to improve their endurance performance. Beet juice is known to contain high levels of a molecule called nitric oxide (NO) which may improve blood flow from lungs to working muscles by causing the dilation (widening) of blood vessels. Select the pair below that includes the most related subdiscipline and physiological system.

a: lungs / muscles

b: motor behavior / endocrine

c: biomechanics / cardiovascular

d: kinesiology / thermoregulation

e: sports nutrition / cardiovascular

2. Select the correct statement below.

a: Physics is a subdiscipline of biomechanics.

b: Physics is a parent discipline of biomechanics.

3. You decide to train for a marathon. After about 6 weeks of successful training you notice that your resting heart rate is lower when you wake up each this morning. Is this a chronic adaptation or an acute response?

a: chronic

b: acute

4. An ischemic stroke occurs when the blood supply to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen … In rehabilitation, a person who has survived a stroke and has some paralysis sometimes has to learn new ways of performing activities of daily living (ADLs). They might see an occupational therapist to get help with learning new movements. What subdiscipline of exercise science is most related to this topic?

a: exercise physiology

b: clinical exercise physiology

c: motor behavior (motor learning)

d: biomechanics

5. When a person lifts weights (resistance exercise training) to increase the size of muscle cells (which increases muscle size and strength), growth hormone and testosterone are involved. What two systems are involved in this?

a: renal system

b: skeletal system

c: endocrine system

d: muscle system

6. In research, there are ways to measure how fast a person can process information and respond to it correctly. These are reaction time tests that involve decision making. Example research topics include:

Older adults and driving ability.
Comparisons of beginner and experienced airline pilots.
The effects of prolonged sleep loss on military personnel.

What subdiscipline of exercise science is this best aligned with?

a: exercise physiology

b: motor behavior

c: biomechanics

a: acute/chronic

b: chronic/acute
