ACSM Ch. 4 & 5

Where does gas exchange occur in the respiratory system?

Alveoli (p. 142)

Exchange of blood gasses and other nutrients within various tissues occurs in the:

Capillaries (p. 137)

The anaerobic system uses which substrate as its primary source for creating ATP?

Carbohydrates (p. 146)

The volume of blood pumped by the heart in liters per minute is defined as:

Cardiac output (p. 138)

A muscle generates enough force to overcome an external resistance and shorten. This is known as which type of action?

Concentric (p. 151)

A physiologic adaptation to aerobic conditioning in untrained individuals will result in a __ in resting HR and a __ in exercise HR at a submaximal effort.

Decrease; decrease (p. 159; Table 5.2)

When a muscle cannot generate sufficient force to overcome external resistance, the muscle lengthens. This is known as which type of action?

Eccentric (p. 151)

What is an acute response to cardiorespiratory exercise?

Increase in stroke volume (p. 138)

What muscle action controls the movement and maintains a constant speed throughout the ROM?

Isokinetic (p. 151)

Higher levels of cardiovascular fitness are associated with:

Lower mortality rates (p. 157)

The most prominent adaptation seen with resistance training is:

Muscle Hypertrophy (p. 157)

What effect does regular exercise have on dyslipidemia?

Regular exercise can increase HDL cholesterol levels. (p. 159 Table 5.2)

___ is the pressure exerted on the arterial wall during ventricles' contaction phase.

Systolic Blood Pressure (p. 138)

Describe the following effect of length changes on the force-generating capacity of shortened muscles:

There is a greater force-generating capacity at the new length, but diminish force-generating capacity at normal resting length. (p. 127)
