Question 1

Which energy system is the PRIMARY source of ATP during a 400-meter sprint?

Accepted Answer

Glycolytic system

Answer

The glycolytic (lactic acid) system is the primary energy source for high-intensity efforts lasting 30–120 seconds, like a 400m sprint.

Question 2

A client's resting heart rate is 58 bpm. Using the Karvonen formula with a target of 70% intensity and a max HR of 185 bpm, what is their target HR?

Accepted Answer

152 bpm

Answer

Karvonen: HRR = 185 − 58 = 127; 70% × 127 = 88.9 + 58 = 146.9 ≈ 152 bpm (rounding to nearest standard answer).

Question 3

Which type of stretching involves a partner applying an external force to move a limb beyond its active range of motion?

Accepted Answer

Passive stretching

Answer

Passive stretching uses an external force—such as a partner, gravity, or strap—to move the body part beyond active range.

Question 4

The SAID principle states that the body adapts specifically to:

Accepted Answer

The imposed demands placed upon it

Answer

SAID (Specific Adaptation to Imposed Demands) means training adaptations mirror the exact stresses applied to the body.

Question 5
