Neural control of lengthening contractions.
A number of studies over the last few decades have established that the control strategy employed by the nervous system during lengthening (eccentric) differs from those used during shortening (concentric) and isometric contractions. The purpose of this review is to summarize current knowledge on the neural control of lengthening contractions. After a brief discussion of methodological issues t...
متن کاملEffect of slow-velocity lengthening contractions on muscle damage induced by fast-velocity lengthening contractions.
This study tested the hypothesis that the first exercise bout consisting of slow-velocity (30° · s(-1)) maximal lengthening contractions would not affect muscle damage in a subsequent bout consisting of fast-velocity (210° · s(-1)) lengthening contractions. Eighteen men were randomly assigned into either a repeated bout group (n = 10) or control group (n = 8). The repeated bout group performed ...
متن کاملHIGHLIGHTED TOPIC Eccentric Exercise Mechanisms of enhanced force production in lengthening (eccentric) muscle contractions
Herzog W. Mechanisms of enhanced force production in lengthening (eccentric) muscle contractions. J Appl Physiol 116: 1407–1417, 2014. First published February 21, 2013; doi:10.1152/japplphysiol.00069.2013.—In contrast to isometric and shortening contractions, many observations made on actively lengthening muscles cannot be readily explained with the sliding filament and cross-bridge theory. Sp...
متن کاملBranched fibers in dystrophic mdx muscle are associated with a loss of force following lengthening contractions.
We demonstrated that the susceptibility of skeletal muscle to injury from lengthening contractions in the dystrophin-deficient mdx mouse is directly linked with the extent of fiber branching within the muscles and that both parameters increase as the mdx animal ages. We subjected isolated extensor digitorum longus muscles to a lengthening contraction protocol of 15% strain and measured the resu...
متن کاملPeak power is reduced following lengthening contractions despite a maintenance of shortening velocity.
Following repetitive lengthening contractions, power (the product of torque and velocity) is impaired during shortening contractions. However, the relative contribution of each component to power loss and the underlying factors are unclear. We investigated neuromuscular properties of the dorsiflexors in 8 males (27 ± 3 years) and 8 females (26 ± 4 years) for a potential sex-related difference b...
