answer

False

question

question

What is the recommended amount of physical activity for improving cardiorespiratory endurance?

answer

20 to 60 min of activity at 70% to 90% of maximal heart rate, three to five days per week

question

During moderate and heavy exercise, heart rate increases linearly with an increase in oxygen uptake.

answer

True

question

The ACSM recommends that adults take part in physical activity 20 to 60 min per day at 60% to 90% of maximal heart rate, seven days per week, to improve cardiorespiratory endurance.

answer

False

question

question

_____ increases rapidly at the onset of physical activity and also increases as a function of exercise intensity.

answer

Ventilation

question

Exercise physiology, biomechanics, sport history, and motor learning are examples of the subdisciplines of kinesiology.
