Journal ArticleDOI
EMG frequency spectrum, muscle structure, and fatigue during dynamic contractions in man
Paavo V. Komi,Per A. Tesch +1 more
TL;DR: Fatigue of the vastus lateralis muscle was studied in healthy well-conditioned students, who differed considerably regarding their muscle fibre type distribution, and it was found that individuals with muscles made up of a high proportion of fast twitch muscle fibres demonstrated higher peak knee extension torque, and a greater susceptibility to fatigue.
Journal ArticleDOI
Lower limb skeletal muscle function after 6 wk of bed rest
TL;DR: It is suggested that the strength loss is also due to factors resulting in decreased neural input to muscle and/or reduced specific tension of muscle, as evidenced by decreased torque/EMG ratio.
Journal ArticleDOI
Changes in lower limb muscle cross-sectional area and tissue fluid volume after transition from standing to supine
TL;DR: Lower limbs show acute fluid shift in response to transition from upright to supine body position, and these fluid shifts merit consideration when tomographic imaging techniques are used to estimate muscle mass and composition.
Journal ArticleDOI
Force and EMG signal patterns during repeated bouts of concentric or eccentric muscle actions
TL;DR: Healthy males (n = 14) performed three bouts of 32 unilateral, maximal voluntary concentric (CON) or eccentric (ECC) quadriceps muscle actions on separate days, and integrated EMG, mean (MPF) and median power frequencies and torque were averaged for seven separate blocks of four consecutive muscle actions.
Journal ArticleDOI
Muscle atrophy and bone loss after 90 days' bed rest and the effects of flywheel resistive exercise and pamidronate: results from the LTBR study.
Jörn Rittweger,Harold M. Frost,Hans Schiessl,Hiroshi Ohshima,Björn Alkner,Per A. Tesch,Dieter Felsenberg +6 more
TL;DR: It is suggested that both countermeasures are only partly effective to preserve BMC (FW and Pam) and mCSA of the lower leg during bed rest and the partial efficacy of flywheel exercise as well as the bones' response to unloading per se underlines the importance of mechanical stimuli.
