Sports Medicine Final Exam Study Guide

A motor nerve plus all of the muscle fibers that it stimulates is a/ an:

• fast-twitch fiber

• motor unit

• slow-twitch fiber

Combined relaxing and contracting of the muscles; an initial isometric contraction against maximum resistance is held at the end of the range of motion, followed by relaxation and passive stretching is known as:

• proprioceptive neuromuscular facilitation

• static stretching

• ballistic stretching

• isokinetic exercise

Progressive resistance exercise is:

• a type of training in which muscles are worked until they reach their capacity.

• the workload on the muscle is increased to further build strength and endurance once the athlete is able to maintain the initial capacity.

• both of the above options

• neither of the above options

The process of muscle atrophy due to disuse, immobilization or starvation; leads to decreased muscle mass and strength. This is the definition of:

• specificity

• overload

• reversibility

• hypertrophy

Fiber in a motor unit that requires a long period of time to generate force; these fibers are resistant to fatigue:

• fast-twitch fiber

• PNF

• slow-twitch fiber

This vocabulary term is usually performed against an immovable object or surface:

• rehabilitation

• PNF exercises

• isokinetic exercises

• isometric exercises

This requires a systematic application of exercise stress:

• rehabilitation

• adaptation

• hypertrophy

• atrophy

____________ conditioning, also known as aerobic or endurance training, refers to activities that put an increased demand on the lungs, heart and other body systems.

• Preseason

• Cardiorespiratory

• Sports

________ stretching was popular a couple decades ago. This method of stretching involves a rhythmical, bouncing action.

• Bounce

• Ballistic

• Isometric

If a muscle is worked less than normal, it _______, or becomes smaller and therefore cannot accommodate the workload it once did.

• atrophies

• hypertrophies

• neither option is correct
