One acute muscular response to maximal exercise is a decrease in?

Intramuscular triglyceride levels

An acute response to exercise is a response that:

Lasts for the duration of the exercise period

Lasts beyond the exercise period

Lasts for the duration of the exercise and recovery period

Is a long term physiological response

Increased rate of diffusion at the muscle results in:

Increased O 2 into the muscle cells from the blood

Increased O 2 diffusing to the muscles cells from alveoli

Increased CO 2 diffusing out of the blood into the muscle cells

Decreased CO 2 diffused out of the muscle cells into the blood cells

When comparing a well trained athlete to an untrained athlete, an untrained athlete will have:

A smaller SV at rest and during max exercise

A larger SV at rest and during max exercise

A smaller HR at rest and during max exercise

A smaller Q at rest and during maximal exercise

During exercise, gas exchange in the muscle occurs via diffusion. Which statement best explains?

Blood O 2 is high, Muscle O 2 is low

Blood O 2 is low, Muscle O 2 is high

Alveoli O 2 is high, Blood O 2 is low

Alveoli O 2 is low, Blood O 2 is high

Why does the body redistribute blood to the muscles?

More blood means more oxygen available

More blood to the muscles means less oxygen available

More blood to muscles means less blood to skin for injuries

More blood means less likely to injure muscles

A-VO 2 difference means

Arterio venous oxygen difference

Venous Arterio oxygen difference

Oxygen arterio venous difference

High arterio-venous oxygen difference shows what?

The ability of the working muscles to get oxygen from blood

The ability of an athlete to take in oxygen

The ability of an athlete to use oxygen

The ability of vessels to get oxygen to muscles

Where lactic acid reaches a prescribed concentration.

The point where you start using lactic acid

The point where you stop using lactic acid

Why does heart rate increase at the onset of sub-maximal exercise?

Due to an increase in oxygen demand to working muscles

Decrease in oxygen demand to working muscles

Increase in motor unit recruitment

Lactate Inflection Point (LIP) is

The last point at which lactate production is equal to lactate removal

Lactate removal exceeds lactate production
