Muscle Contractions

Front

What is a concentric contraction?

Back

A concentric contraction occurs when a muscle shortens while generating force, such as when lifting a weight.

Front

What is an eccentric contraction?

Back

An eccentric contraction occurs when a muscle lengthens while generating force, such as when lowering a weight.

Front

What is an isometric contraction?

Back

An isometric contraction occurs when a muscle generates force without changing its length, such as holding a weight in a fixed position.

Front

What type of contraction occurs when the quadriceps are engaged during a jump?

Back

Concentric contraction.

Front

Which muscle undergoes concentric contraction during the upward phase of a press?

Back

Triceps.

Front

What type of contraction do the biceps undergo when lowering weights?

Back

Isotonic eccentric contraction.

Front

Can isometric exercises build muscle?

Back

False.

Front

What is the most effective type of contraction for building muscle?

Back

Isokinetic.

Front

Define isotonic contraction.

Back

An isotonic contraction involves a change in muscle length while the muscle tension remains constant, such as lifting or lowering a weight.

Front

What is the difference between isotonic and isometric contractions?

Back

Isotonic contractions change muscle length, while isometric contractions do not change muscle length.
