"Contraction strength" refers to the intensity or force with which a muscle tightens or contracts. It measures how strong or powerful the muscle's contraction is. Full definition
Changes in neural drive after explosive contraction and maximal (sustained) contraction strength training are specific to the contraction duration (Balshaw et al. 2016). (strengthandconditioningresearch.com)
Methodist, resting a bit, eating some, trying pitocin, getting an inter uterine monitor to determine inside contraction strength and finding that my contractions were not strong enough to get baby out, we were left with the recommendation that we have a c section. (believemidwiferyservices.com)
Further studies are needed to elucidate the feedback loops between ECM stiffening and cell contraction strength. (sciencedaily.com)
