Exam 14: Physiology of Training: Effect on Vo2 Max, Performance, and Strength

Four-to-ten weeks of anaerobic training (high intensity exercise lasting 10-30 seconds)can increase the peak anaerobic capacity by ______ across individuals.

The majority of evidence demonstrates that resistance training-induced muscle hypertrophy is the result of muscle fiber hyperplasia. 40.The initial decrease in VO₂ max with detraining occurs because skeletal muscle adaptations (a-vO₂ difference)are lost.

Endurance exercise training programs (e.g. ,3 days/week @ 60% VO₂ max for 12 weeks)lasting typically result in a ______% improvement in VO₂ max.

In a "two-legged" maximal cycle ergometer test,if each leg were to vasodilate to the extent experienced in a one-legged VO₂ max test,mean arterial blood pressure would fall below normal levels.

Which of the following factors does NOT contribute to the endurance exercise training-induced increases in fat metabolism during exercise?

After a 15-week program of endurance exercise training,which of the following cardiovascular variables does NOT decrease after 14 days of detraining?

Heritability (i.e. ,genetics)determines approximately _____% of VO2 max variability in sedentary adults.

Reducing the number of motor units required to perform an exercise task may reduce the heart rate and ventilation required to perform the task.

Following endurance training,maximal cardiac output during exercise is increased due to an increase in the thickness of the left ventricular wall (i.e,ventricular muscle mass increases).

Which of the following factors does NOT contribute to the endurance exercise training-induced improvement in stroke volume during exercise?

Which of the following endurance training adaptations assist in maintaining acid-base balance during exercise?

Which of the following physiological factors does NOT contribute to the endurance exercise training-induced increase in the maximal a-vO₂ difference?

Following an acute bout of endurance exercise training,the rise in the activity of calcinurin,calmodulin kinase,and AMP kinases occurs within _____ following the exercise session.

The enhanced capacity of the trained muscle to use fatty acids as a fuel results in

The increase in VO₂ max that occurs following 4 months of endurance exercise training results from an increase in both maximal cardiac output and maximal a-vO₂ difference.Relatively short durations of endurance exercise training (e.g. ,1-4 months)increases VO₂ max primarily by increasing

A single bout of resistance exercise training results in an increase in skeletal muscle protein synthesis.This exercise-induced increase in muscle protein synthesis can occur within _____ following the exercise session.

The average VO₂ max value for the young (e.g. ,21 years old)male sedentary population is approximately

Following an acute bout of endurance exercise training,the increase in mitochondrial biogenesis occurs within _____ following the completion of the exercise session.

Following a single bout of resistance exercise training,muscle protein synthesis can remain elevated above baseline for as much as ______ in both trained and untrained individuals.

Cross-sectional studies demonstrate that the physiological variable responsible for the large variation in VO₂ max across the normal population is maximal
