ACE Cardiorespiratory Program Design 5

Question 1

Which physiological adaptation is the PRIMARY long-term benefit of consistent aerobic endurance training?

Accepted Answer

Increased stroke volume at rest and during exercise

Answer

Chronic aerobic training enlarges the left ventricle (cardiac hypertrophy), dramatically increasing stroke volume and thus cardiac output.

Question 2

Fartlek training differs from structured interval training PRIMARILY because it:

Accepted Answer

Involves random, unstructured changes in pace and terrain

Answer

Fartlek (Swedish for 'speed play') varies intensity spontaneously based on feel or terrain rather than prescribed work-rest ratios.

Question 3

For a client with obesity and low fitness, which cardiorespiratory training approach minimizes joint stress while still elevating heart rate?

Accepted Answer

Water aerobics or pool walking

Answer

Aquatic exercise provides buoyancy that reduces joint loading by up to 90% while still allowing elevated heart rate and caloric expenditure.

Question 4

The principle of specificity in cardiorespiratory training means that a cyclist training only on a bike will see:

Accepted Answer

Greater cycling performance gains than running performance gains

Answer

Specificity dictates that adaptations are greatest in the trained mode, so cycling training primarily improves cycling economy and performance.

Question 5

A client completes a 1-mile walk test and their heart rate at completion is used to estimate VO2max. Which test protocol does this describe?

Accepted Answer

Rockport Fitness Walking Test

Answer

The Rockport Fitness Walking Test uses completion time and post-test heart rate from a 1-mile walk to estimate VO2max.
