Question 1

The SAID principle (Specific Adaptation to Imposed Demands) states that:

Accepted Answer

The body adapts specifically to the type, intensity, and mode of training imposed

Answer

The SAID principle states that the body makes specific physiological adaptations in response to the specific demands placed on it. Training adaptations are specific to the movement pattern, speed, load, and energy system used.

Question 2

According to the ACSM, the recommended intensity for aerobic exercise to improve cardiovascular fitness is:

Accepted Answer

40-85% of VO2 reserve or heart rate reserve

Answer

ACSM recommends 40-85% of VO2 reserve (or HRR) for cardiovascular fitness improvement, with beginners starting at the lower end (40-60%) and progressing to moderate-to-vigorous intensities.

Question 3

Open kinetic chain (OKC) knee extension exercises are contraindicated during early ACL reconstruction rehabilitation primarily because:

Accepted Answer

Terminal knee extension creates anterior shear forces at the tibia, placing high stress on the healing ACL graft

Answer

During terminal OKC knee extension (from approximately 40 degrees to full extension), the quadriceps pull anteriorly on the tibia via the patellar tendon, placing anterior tibial shear forces that stress an ACL graft.

Question 4

What is the primary metabolic pathway used during high-intensity exercise lasting 30 seconds to 2 minutes?

Accepted Answer

Glycolytic (lactic acid) system

Answer

The glycolytic (lactic acid) system is the primary energy source for high-intensity exercise lasting approximately 30 seconds to 2 minutes, producing ATP through anaerobic glycolysis with lactate as a byproduct.

Question 5

Proprioceptive neuromuscular facilitation (PNF) techniques rely on which neurophysiological mechanism for inhibiting a tight muscle?

Accepted Answer

Both reciprocal inhibition and autogenic inhibition

Answer

PNF stretching uses both autogenic inhibition (GTO activation during contract-relax reduces agonist tension) and reciprocal inhibition (antagonist contraction inhibits agonist) to achieve greater ROM.
