eccentric and concentric muscle contractions

What is the difference between concentric and ecentric muscle contractions

Concentric contractions shorten the muscle where as eccentric contractions lengthen the muscle

During what type of contraction does the muscle lengthen

Eccentric

What happens to the sarcomere length during a concentric contraction

The sarcomere shortens , pulling the z lines together

Which type of muscle contraction typically produces greater force

Eccentric

when lowering a dumbbell in a bicep curl what type of muscle contraction happens in the bicep brachii

Eccentric

During the upwards phase of the squat what type of contraction occurs in the quadriceps

Concentric

Give one example of an eccentric contraction during walking

When the quadriceps control knee flexion

When landing from a jump what type of contraction occurs in the quadriceps

Eccentric

In a push up what type of contraction occurs in the triceps during the lowering phase

Eccentric

How does the energy cost of eccentric contractions compare to concentric

Eccentric contractions require less energy
