What are the five recommendations for selecting the right running shoe?

-Try on shoes at the end of the day

-Try on both shoes

-Allow for a thumbnail's length of space in the toe box

-Bring running socks, insoles, and orthotics if used

-Make sure shoes are comfortable right out of the box

What type of shoe support is appropriate for overpronation?

Stability shoes with structured support or motion control shoes

What are the physiological adaptions associated with chronic strength training?

-Increased endurance, size, strength, and power

-Increased fat metabolism

-Increased Bone density

-Increased functional capacity

-Decreased falls and injuries

What is agonist muscles?

A muscle that contracts and causes movement

What is antagonist muscles?

A muscle that causes movement in the opposite direction and opposes the agonist muscle

What are stabilizer muscles?

A muscle that contracts to maintain posture and immobilize a joint

How do the muscles work together in a lift?

Concentric and eccentric muscle contractions happen at the same time. As you lift the weight up toward your shoulder during an arm curl, your bicep muscle shortens (concentric muscle contraction) and your triceps lengthens (eccentric muscle contraction)

What is concentric contractions?

A contraction that results in muscle shortening. The force produced by the muscle is greater than the force of the resistance cause motion against gravity

What are eccentric contractions?

A contraction that results in muscle lengthening. The force of the resistance is greater than the force produced by the muscle

What are isometric contractions?

A contraction in which there is no change in the muscle length. The force produced by the muscle equals the force of the resistance

What is a compound lift?

A movement that recruits one or more major muscle groups and it involves two or more joints

What are the five compound lifts?

-Bench

-Row

-Press

-Squat

-Deadlift

Between the ages of 30 and 65, the average American loses ... pounds of muscle and gains ... pounds of fat each year

1/2;1

At what age does bone density peak?

25 years old

Can transition between muscle fiber types occur with chronic strength training?

Endurance training induces the transition from fast-twitch muscle fiber to slow-twitch muscle fiber, whereas strength training results in slow-twitch to fast-twitch muscle fiber transition

What does Henneman's size principle state?

When muscles are loaded, the smaller slow-twitch fibers are activated before the large fast-twitch fibers

What characterizes sarcoplasmic hypertrophy?

Growth of sarcoplasm of the muscle fiber (bodybuilding)

What are the four types of stretching

Static, ballistic, dynamic, and PNF

What is static stretching?

A type of structure that uses a slow and constant stretch best performed after a training session

What is ballistic stretching?

Bouncy, jerky-type movements. May activate muscle spindles, which are receptors located in muscle bellies. Muscle spindles are activated by quick stretch/lengthening and this causes contraction

What is dynamic stretching?

Active stretching that uses dynamic movements and sport-specific drills to prepare muscles for activity to follow. Controlled movements best performed before training. Performed in all three planes of movement

What is PNF stretching?

Uses a partner and involves both passive and active muscle actions. Alternating contraction and relaxation of the same muscle. Best performed after a training session

Which stretch isn't recommended?

Ballistic stretching

What are the three basic phases of prehab?

Soft tissue work, dynamic stretching, movement specific activation

What is soft tissue work?

Helps to break up adhesions (scar tissue) in muscle and fascia. Uses a foam roller, massage stick, and lacrosse ball. Can be performed before and/or after a training session
