Which of the following would be a chronic adaptation to exercise.Group of answer choicesHeart rate increases during a rowing exercise.Muscles becomes fatigued during sprinting.Muscles are larger following 9 months of resistance training.Blood pressure increases during the bench press exercise

Which type of exercise is most likely to lead to adaptive changes in muscle strength?Question 9Answera.Long-distance runningb.Swimmingc.Yogad.Resistance training

The increase in cardiac output that occurs during exercise is due to_________a.both an increase in mean arterial pressure and a decrease in vascular resistance.b.an increase in mean arterial blood pressure only.c.a decrease in vascular resistance only.d.an increase in heart rate and a decrease in mean arterial blood pressure.

The initial increase in heart rate at the onset of incremental exercise is due to:Group of answer choicesincreased plasma adrenalinereduced vagal activityincreased venous return due to activation of the muscle pump

Endurance training results inGroup of answer choicesmuscle atrophy.an increase in blood vessels to a muscle.muscle hypertrophy.an increase in muscle fibers.

Following endurance training, heart rate at a given oxygen uptake and cardiac output is lower because:Group of answer choicesstroke volume is increasedthe heart is less sensitive to adrenergic stimulationred cell mass is increased
