Perform Ten Resistance Training Exercise

Decent Essays

3. Perform ten resistance training exercises and describe which phase of the exercise is the eccentric, concentric and isometric phase of the movement. At which phase is the muscle the strongest? Why?

When performing the bench press, lowering the bar to your chest (down phase) this movement is considered an eccentric contraction. When lifting the bar off your chest (up phase) this movement is considered a concentric contraction. If we modify the exercise and we bring the weight down to the chest and hold this position, this fixed position of the bar is considered an isometric contraction. During the up phase, the pectoralis major is at its strongest because the muscle is contracted at its full potential, holding and maintaining the weight …show more content…

As the body lowers in this exercise, the chest, shoulders, triceps, and abdominals are all contracted, which is a concentric contraction. As the body rises back up to the starting position, this movement is an eccentric contraction. The muscles are at its strongest in this exercise when the body is in the down phase and maintaining a muscle contraction on the way back up to the starting position.

Upright rows, when the barbell is raised, this movement is a concentric contraction. During this contraction, the trapezius are at its strongest in this point in the movement. As the weight is lowered back to its starting position, this movement downward is an eccentric contraction.

Barbell rows, when the body is about to perform the exercise (preparatory phase) and is griping the bar, this is an isometric contraction. When the bar is raised and touching the upper abdominals, this is a concentric contraction. The latissimus dorsi, trapezius, posterior deltoids and biceps, are all activated during this exercise and are the strongest when the bar is touching the upper portion of the abdominals. When the bar is lowered and brought back to the starting position, this is an eccentric
