Assessing the effect of bench press muscle action, Mookerje & Ratamess (1999) found a main difference in elbow flexion and extension action durations such that the elbow flexion action was significantly shorter than the extension duration, most likely due to force development being greater eccentrically than concentrically.

Whatever the exact underlying causes, from this general research we can deduce that muscle strain injury is caused during actively lengthening muscle actions, and is caused either by the energy absorbed or the size of the strain.

You're going to use a lot of power and momentum on one side to get the weight moving but, instead of using muscle action on that same side to stop / slow the movement, you'll use the core muscles on your OTHER side to «catch it,» then stop it, then whip the dumbell back around to the original start position for another go.

Importantly, muscle fibers are arranged in groups of fascicles but it is known from animal experiments that individual muscle fibers do not typically run the entire length of the fascicle and some may be arranged in series along the length of a muscle, potentially in order to reduce the effects of a slow propagation speed of muscle action potentials (Lieber & Fridén, 2000).

Bones are an essential component of our body, with numerous functions that include providing mechanical support of soft tissues, acting as levers for muscle action, and protecting the central nervous system.
