Sex comparisons of non-local muscle fatigue in human elbow flexors and knee extensors
OBJECTIVES To examine non-local muscle fatigue (NLMF) in both contralateral homologous and non-related heterogonous muscles for both sexes. METHODS Ten men and nine women participated in this study. After the familiarization visit, subjects completed four separate randomly sequenced experimental visits, during which the fatiguing interventions (six sets of 30-second maximal isometric contract...
متن کاملEffect of elbow joint angle on the magnitude of muscle damage to the elbow flexors.
PURPOSE It has been shown that eccentric actions at a long muscle length result in a larger decrease in force and more muscle tenderness compared with those at a short muscle length. To further investigate the effect of elbow joint angle on the development of muscle damage, this study compared two maximal eccentric exercise regimens in which the starting position of the action was different, bu...
متن کاملDifference in the magnitude of muscle damage between elbow flexors and knee extensors eccentric exercises.
The aim of this study was to investigate the difference in the magnitude of muscle damage between maximal eccentric exercises of the elbow flexors (EF) and knee extensors (KE). Twelve sedentary male volunteers participated in the study. Range of motion (ROM), isometric peak torque (IPT), delayed onset of muscle soreness (DOMS), creatine kinase activity (CK), and myoglobin concentration (Mb) wer...
متن کاملDifferential age-related changes in motor unit properties between elbow flexors and extensors.
AIM Healthy adult ageing of the human neuromuscular system is comprised of changes that include atrophy, weakness and slowed movements with reduced spinal motor neurone output expressed by lower motor unit discharge rates (MUDRs). The latter observation has been obtained mostly from hand and lower limb muscles. The purpose was to determine the extent to which elbow flexor and extensor contracti...
متن کاملTHE NORMAL CARRYING ANGLE OF THE ELBOW IN SHIRAZ
The normal carrying angle in Shiraz population was measured on the basis of sex and age. The right elbow angle of 4266 cases was examined from birth to 30 years old. This study found the carrying angle in 2540 females to be 7.20 (range 2-19) and in 1726 males to be 6.40 (range 2-11), a 0.80 difference. A significant difference (p= 0.05) was found in relation to age. There is a gradual incr...
