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

Following endurance training,afterload decreases during maximal exercise because there is a decrease in sympathetic vasoconstrictor activity in the arterioles of the exercising muscles.

Endurance training has been shown to reduce the oxygen deficit in subjects performing a submaximal exercise.This is due to

Endurance exercise training results in an increased turnover of mitochondria in skeletal muscle.The process of removing old and damaged mitochondria is called______.

In theory,concurrent resistance and endurance exercise training can impair muscle protein synthesis following a bout of resistance exercise.The proposed mechanism to explain this inhibition is_____________________________________.

During the first 10 weeks of a resistance training program,the initial increase in muscular strength are due primarily to

The heart rate and ventilatory responses to a fixed submaximal work rate are lower (i.e. ,lower heart rate and lower minute ventilation)following an endurance training program.This training-induced adaptation is primarily due to changes in the

Several mechanisms have been proposed to explain why concurrent endurance and resistance (strength)training impedes strength development compared to strength training alone.Which of the following mechanisms have NOT been proposed to explain why concurrent training impedes strength development?

High responders to endurance exercise training (i.e. ,individuals that achieve large increases in VO₂ max)can achieve up to______% improvement in VO₂ max following a prolonged and intense training program.

Which of the following endurance training adaptations does NOT result in lower lactate production in the contracting muscles?

Research indicates that anyone can increase his or her VO₂ max with training,yet a genetic predisposition is required to have a VO₂ max comparable to that of an elite endurance athlete.

It is well known that resistance exercise training promotes an increase in muscle protein synthesis by activating the mechanistic target of rapamyosin (mTOR)which results in increased protein synthesis.Recent evidence suggests that two signaling molecules interact to directly activate mTOR.These molecules are:

A single bout of resistance exercise training increases muscle protein synthesis by as much as ______% above resting levels?
