An individual will develop adequate muscular strength, endurance, and flexibility through participation in sport activities.

False

During the arm pull/leg push phase of the rowing exercise the knee joint performs flexion.

False

During the return phase of rowing exercise the wrist and hand joints perform extension.

False

It is not necessary to analyze each individual's exercise and skill technique in order to specifically design an exercise program to meet his/her needs.

False

Muscular strength, muscular endurance, and flexibility are general body characteristics that are not specific to each body area and muscle group.

False

The abdominal curl-up does not strengthen the internal and external oblique abdominals unless trunk rotation is included.

False

The dead lift is a closed kinetic chain exercise.

False

The quadriceps muscle group functions as a decelerator to knee joint flexion in weight-bearing movements by contracting concentrically to prevent too rapid of a downward movement.

False

When performing a "squat" exercise the hip is extended during the lowering phase.

False

A "dead lift" exercise is divided into two phases.

True

Compared to an untrained person, a well-trained person will see relatively minor improvements in the amount of weight that can be lifted over the same period of time.

True

Concentric muscle actions are the shortening contraction of muscles against gravity or a resistance.

True

During the arm pull/leg push phase of the rowing exercise the shoulder joint performs extension.

True

During the return phase of rowing exercise the hip joint performs flexion.

True

Eccentric actions occur when muscles lengthen under tension to control the joints moving with gravity or a resistance.

True

Many types of back pain and other physical ailments can be avoided through proper maintenance of the musculoskeletal system.

True

Muscles may shorten or lengthen in the absence of a contraction through passive movement caused by other contracting muscles.

True

The "SAID Principle" indicates that strength gains beyond the range of motion utilized in the training are usually minimal.

True

The "SAID Principle" is applicable in every form of muscle training as well as to the systems of body.

True

The "alternating prone extension" exercise can be broken down to two separate phases.

True

The abdominal curl-up strengthens the hip flexors.

True

True

The specific needs of each individual should be specifically addressed when designing an exercise program.

True

When using free weights for strength training it is important to ensure that one group of muscles is not overdeveloped and another is underdeveloped.

True
