Kin 242 Chapter 4 Practice Quiz

Which of the following stretching techniques is generally used for increasing flexibility? Group of answer choices

proprioceptive neuromuscular facilitation

When a sprinter runs a 50-yard dash, which structure within the muscle is primarily being used?

fast twitch

What is the primary reason for the difference in strength between males and females?

Females have a higher percentage of body fat, which decreases the strength/body weight ratio.

Which of the following statements is true of isokinetic exercises?

In isokinetic exercises, resistance is given at a fixed velocity of movement with accommodating resistance.

Which of the following statements is true of ballistic stretching?

It involves a bouncing movement in which repetitive contractions of the agonist muscle are used to produce quick stretches of the antagonist muscle.

Which of the following is true of bodyweight training?

It uses the force of gravity as resistance.

Which of the following is defined as an approach to conditioning that attempts to bring about peak performance, while reducing injuries and overtraining in athletes, by developing a training and conditioning program to be followed throughout the various seasons?

Periodization

Which of the following exercises strengthens muscles through a contraction that overcomes some fixed resistance produced by equipment such as dumbbells, barbells, various weight machines, or exercise tubing and uses isotonic contractions in which force is generated while the muscle is changing in length? Group of answer choices

Progressive resistance exercise

Which of the following statements is true of isometric exercises?

They are commonly used in injury rehabilitation or reconditioning.

If the intensity of an activity is low enough that the cardiovascular system can supply enough oxygen to continue the activity for long periods, the activity is an _____.

aerobic

A dynamic warm-up that is usually used to prepare for physical activity can be done in _____.

as little as 5 minutes or as long as 20 minutes

Which of the following uses a series of exercise stations that consist of various combinations of weight training, flexibility, bodyweight training, and brief aerobic exercises?

circuit training

Currently, muscles are classified into two basic types: slow-twitch powerful fibers and fast-twitch endurance fibers.

false

During the strength phase of the preparatory period, training is at a low intensity with a high volume of repetitions.

false

Dynamic stretching is unlikely to cause muscular soreness and is commonly used in injury rehabilitation of sore or strained muscles. Group of answer choices

false

Hold-relax is an example of a static stretching technique.

false

Open-kinetic chain exercises consist of those exercises in which the foot or hand is in contact with the ground or some other surface.

false

Passive range of motion requires muscle contraction.

false

When lifting a weight in the hand, the biceps muscle in the upper arm is shortening as it contracts, which is an eccentric contraction.

false

When performing a knee extension exercise, the hamstring group acts as the agonist muscle.

false

A soccer player running ten 120-yard sprints in under 20 seconds each, with a 1-minute walking recovery period between each sprint is an example of _____.

interval training

Which of the following training techniques consists of alternating periods of relatively intense work and active recovery?

interval training

Which of the following involves a muscle contraction in which the length of the muscle is changing while the contraction is performed at a constant velocity?

isokinetic

Which of the following involves a muscle contraction in which the length of the muscle remains constant while tension develops toward a maximum force against an immovable resistance?

isometric exercise

A bicep curl using a dumbbell is an example of a(n) _____.

isotonic

Which of the following describes the season when conditioning is dedicated to unstructured, recreational activities?

off season

Hops, bounds, and depth jumps are forms of ____

plyometric

Which of the following is a technique of exercise that involves a rapid eccentric stretch of a muscle, followed immediately by a rapid concentric contraction of that muscle for the purpose of producing a forceful explosive movement over a short period? Group of answer choices

plyometric exercise

Which of the following terms is defined as the ability to generate force rapidly?

power

Which of the following involves passively stretching a muscle by placing it in a maximal position of stretch, or its endpoint where there is resistance to stretch, and holding it there for an extended time? Group of answer choices

static

A trigger point is an area of tenderness in a tight band of muscle, and painful or active trigger points most often develop because of some mechanical stress to the muscle.

true

Cardiorespiratory endurance refers to the body's ability to transport and use oxygen efficiently and is essential to minimize fatigue, which can lead to injury.

true

Continuous training has four considerations: the type, the frequency, the duration, and the intensity of physical activities.

true

In training and conditioning, the use of closed-chain strengthening techniques is a widely used technique because these exercises tend to be more functional, as most sports activities are weight-bearing.

true

It is possible to generate greater amounts of force against resistance with an eccentric contraction than with a concentric contraction.

true

Muscular endurance is the ability to perform repetitive muscular contractions against some resistance for an extended time, and as muscular strength increases, there tends to be a corresponding increase in endurance.

true

Muscular strength is proportional to the size of a muscle as determined by the cross-sectional diameter of the muscle fibers.

true

Overtraining can have a negative effect on the development of muscular strength; engaging in proper and efficient resistance training, eating a proper diet, and getting appropriate rest can all minimize the potential negative effects of overtraining.

true

Push-ups and sit-ups are examples of bodyweight strengthening exercises.

true

Stretching does not necessarily improve performance, nor does it help to prevent injury.

true

The SAID principle states that when the body is subjected to stresses and overloads of varying intensities, it will gradually adapt to overcome whatever demands are placed on it and, in doing so, minimize the potential for injury.

true

The muscle being stretched in response to contraction of the agonist muscle is called the antagonist muscle.

true
