ACE Exercise Science & Application 3

Question 1

The SAID principle in exercise programming refers to:

Accepted Answer

Specific Adaptations to Imposed Demands

Answer

SAID stands for Specific Adaptations to Imposed Demands, meaning the body adapts specifically to the type of stress placed upon it.

Question 2

During the stretch-shortening cycle, the amortization phase refers to:

Accepted Answer

The brief transition between eccentric and concentric phases

Answer

The amortization phase is the brief isometric coupling period between the eccentric (pre-stretch) and concentric (propulsion) phases.

Question 3

Which statement about motor unit recruitment is MOST accurate?

Accepted Answer

Motor units are recruited in an all-or-none fashion according to the size principle

Answer

The size principle states that motor units are recruited from smallest (slow-twitch) to largest (fast-twitch) as force demand increases, and each fires in an all-or-none manner.

Question 4

A personal trainer is assessing a client's VO2max using a submaximal cycle ergometer test. The predicted VO2max relies on the assumption that:

Accepted Answer

Heart rate response to submaximal work is consistent and predictable

Answer

Submaximal VO2max tests assume a linear relationship between heart rate and oxygen consumption and that submaximal HR responses are predictable and consistent.

Question 5

Excess post-exercise oxygen consumption (EPOC) is PRIMARILY caused by:

Accepted Answer

Elevated metabolic rate needed to restore homeostasis after exercise

Answer

EPOC reflects the elevated oxygen uptake needed to restore phosphocreatine, clear lactate, reduce body temperature, and return the body to its pre-exercise state.
