Concentric and eccentric exercises

Concentric And Eccentric Exercises. Studies show that eccentric exercise results in less oxygen consumption greater force production and less energy expenditure than concentric strengthening- or the active shortening of the muscle. Examples of eccentric exercises include. Retraction in J Ultrasound Med. Results concluded that resistance training eccentric contractions promoted strength gain.

The force produced by a concentric contraction is always less than the muscles maximum force. When you slowly lower your body you are moving eccentrically. Lowering the barbell toward your chest in a bench press Lowering into a parallel squat position in a squat Lowering into the bottom of a pushup Bringing a barbell back to the ground at the end of a deadlift Lowering your torso back to the ground in a situp. In summary there are a number of mechanisms that could theoretically differentiate the effect of eccentric from concentric exercise on tendon but there is no evidence that these mechanisms actually play a role or are beneficial.

Bench presses and squats for example start with an eccentric phase whereas deadlifts and pull-ups start with a concentric phase.

This makes them especially key for endurance fighting fatigue and improving performance in movements like running or swimming.

In contrast there is evidence from animal and human studies that suggests a lack of differential effect of eccentric versus concentric exercises.
