MPT Therapeutic Exercise and Functional Rehabilitation 1

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

Exercises must be performed daily to maintain gains

Answer

Muscles can only strengthen in the plane they are trained

Answer

Aerobic conditioning automatically improves strength

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

20-40% of VO2 reserve

Answer

90-100% of maximum heart rate

Answer

Below 30% of maximum heart rate

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

They are too easy and do not load the graft

Answer

They cannot be performed with a brace

Answer

They cause excessive patellar compression

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

Alactic anaerobic (ATP-PC) system

Answer

Oxidative (aerobic) system

Answer

Beta-oxidation of free fatty acids

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

Reciprocal inhibition (antagonist contraction inhibits agonist)

Answer

Autogenic inhibition via Golgi tendon organs during muscle contraction

Answer

Direct reflex arc inhibition of the motor cortex

Question 6

The overload principle in resistance training states that muscle adaptations occur only when:

Accepted Answer

Training load exceeds what the body is currently accustomed to, progressively challenging the neuromuscular system

Answer

Exercise is performed at the same load for extended periods

Answer

Exercise is performed to failure on every set

Answer

The same exercise is performed every day without variation
