Aging of human skeletal muscles.
Normal aging in humans is associated with progressive decrease in skeletal muscle mass and strength (sarcopenia) which contributes to frailty and falls. The age associated changes in body composition result from lower levels of anabolic hormones, oxidative damage, neuromuscular alterations and a general decrease in muscle protein turnover. In this review we discuss the potential mechanisms and ...
متن کاملEffect of Aerobic Exercise with Blood Flow Restriction on Mitochondrial Dynamics Proteins of Human Skeletal Muscles
Background: Aerobic exercise with Blood Flow Restriction (BFR) plays an important role in skeletal muscle adaptation; however, the effects of this type of exercise on mitochondrial dynamics proteins are unclear. Objective: The purpose of this study was to investigate the effect of aerobic exercise with and without BFR on mitochondrial dynamics proteins of human skeletal muscles. Methods: Pa...
متن کاملInvestigation of age-related changes in LMNA splicing and expression of progerin in human skeletal muscles.
Age-related changes in splice-forms of LMNA, which encodes the nuclear lamina proteins lamin A/C, have not been investigated in skeletal muscle. In the rare premature ageing disease, Hutchinson-Gilford progeria syndrome (HGPS), de novo point mutations in LMNA activate a cryptic splice site in exon 11, resulting in a 150 base deletion in LMNA mRNA and accumulation of a truncated protein isoform,...
متن کاملPassive elongation of muscle fascicles in human muscles with short and long tendons
This study tested the hypothesis that the ratio of changes in muscle fascicle and tendon length that occurs with joint movement scales linearly with the ratio of the slack lengths of the muscle fascicles and tendons. We compared the contribution of muscle fascicles to passive muscle-tendon lengthening in muscles with relatively short and long fascicles. Fifteen healthy adults participated in th...
متن کاملOperating length and velocity of human M. vastus lateralis fascicles during vertical jumping
Humans achieve greater jump height during a counter-movement jump (CMJ) than in a squat jump (SJ). However, the crucial difference is the mean mechanical power output during the propulsion phase, which could be determined by intrinsic neuro-muscular mechanisms for power production. We measured M. vastus lateralis (VL) fascicle length changes and activation patterns and assessed the force-length...
