The amount of weight an individual can lift during one maximum effort is:

	muscular endurance.
	muscular strength.
	cardiorespiratory endurance.
	progressive resistance.

The ability to generate force over and over again is:

	muscular endurance.
	muscular strength.

Recovery index is the measurement of heart rate during _________ recovery periods following a submaximal step test.

Skeletal muscles are attached bones by:

	tendons.
	ligaments.
	nerves.
	fascia.

Muscle contractions are classified into two major categories:

	isometric and isokinetic.
	isometric and plyometric.
	isotonic and isometric.
	isokinetic and plyometric.

Contractions that result in movement of a body part:

	isometric
	isokinetic
	isotonic
	plyometric

Contracting a muscle at a fixed angle against an immovable object is called a:

	isokinetic contraction.
	plyometric contraction.
	isotonic contraction.
	isometric contraction.

The static nature of isometric muscle contractions can lead to breath holding, called:

	valsalva maneuver.
	overload principle.
	hypertrophy.
	atrophy.

The greatest strength gains are made with a training program using ______ repetitions and ______ resistance.

	low : high
	low : low
	high : high
	high : low

The greatest improvement in endurance is made using ______ repetitions and ______ resistance.

	low : high
	high : low
	low : low
	high : high

The intensity of exercise in both isotonic and isokinetic weight training programs is measured by the concept of the:

	overload principle.
	specificity principle.
	repetition maximum.
	valsalva maneuver.

The process of involving more muscle fibers to produce increased muscular force is called:

	repetition maximum.
	specificity.
	overload.
	fiber recruitment.

The two primary physiological factors that determine the amount of force that can be generated by a muscle are:

	length and size.
	size and neural influences.
	neural influences and length.
	size and location on bone.

When muscle size is increased it is called:

	hyperplasia.
	atrophy.
	hypertrophy.
	fiber recruitment.

Strength training can also promote the formation of new muscle fibers, which is called:

	hypertrophy.
	hyperplasia.
	atrophy.
	fiber recruitment.

Exercises that require the use of machines that govern the speed of movement during muscle contraction throughout the range of motion:

	isotonic exercises
	isometric exercises
	plyometric exercises
	isokinetic exercises

An application of the overload principle applied to strength and endurance exercise programs:

	progressive resistance exercise
	cardiorespiratory endurance exercise
	plyometrics
	anaerobic exercise

The principle that states that a muscle will adapt only when it works against a workload that is greater than normal is:

	specificity.
	consistency.
	progression.
	overload.

Muscle contractions that result in muscle shortening:

	eccentric contractions
	concentric contractions
	slow-twitch contractions
	fast-twitch contractions

Muscle contractions in which the muscle exerts force while it lengthens:

	eccentric contractions
	concentric contractions
	slow-twitch contractions
	fast-twitch contractions

Muscle fibers that are highly resistant to fatigue:

	fast-twitch fibers
	intermediate fibers
	slow-twitch fibers
	eccentric fibers

Muscle fibers that shorten rapidly:

	slow-twitch fibers
	fast-twitch fibers
	intermediate fibers
	concentric fibers

A marathon runner will have a greater percentage of _________ muscle fibers:

	slow-twitch
	fast-twitch
	intermediate
	eccentric

Strength training cannot reduce:

	low-back pain.
	incidence of exercise-related injuries.
	incidence of osteoporosis.
	body fat.

Recent studies have shown that strength training improves:

	personal appearance.
	self-esteem.
	overall feelings of well-being.
	all of the above

Which of the following are NOT consequences of anabolic steroid use?

	increased blood pressure
	liver cancer
	prostate cancer
	increased levels of "good" cholesterol

The number of exercises performed consecutively:

	a repetition
	a set
	repetition maximum
	a prescription

Muscle cramps are painful, uncontrolled muscle contractions that are caused by all of the following EXCEPT:

	loss of water and minerals from sweating.
	irritation or damage to the motor nerves.
	muscle overuse.
	drinking athletic drinks during or after exercise.

Isotonic and isometric training utilizes the _______ metabolic system.

	anaerobic
	aerobic
	intermediate
