Mechano-transduction to muscle protein synthesis is modulated by FAKSpringer Science and Business Media LLC - Tập 106 - Trang 389-398 - 2009

We examined the involvement of focal adhesion kinase (FAK) in mechano-regulated signalling to protein synthesis by combining muscle-targeted transgenesis with a physiological model for un- and reloading of hindlimbs. Transfections of mouse tibialis anterior muscle with a FAK expression construct increased FAK protein 1.6-fold versus empty transfection in the contralateral leg and elevated FAK conc...... hiện toàn bộ
Effect of human exposure to altitude on muscle endurance during isometric contractionsSpringer Science and Business Media LLC - - 2001

The aim of this study was to evaluate the influence of exposure to altitude on muscle endurance during isometric contractions. Six sedentary subjects were studied. Surface electromyograph (sEMG) activity was recorded from the right biceps brachii (BB) during exhausting isometric exercise at 80% maximal voluntary contraction. Experiments were performed before, during and 6 months after a 12 day st...... hiện toàn bộ
Validity of the W170 test for predicting maximal oxygen intakeSpringer Science and Business Media LLC - Tập 37 - Trang 191-196 - 1977
George T. Jessup
Recent research has related pedalling frequency to perceived exertion, indicating that subjects pedalling at higher frequencies tend to perceive lower levels of exertion. If tests administered at higher pedalling speeds are valid, then more accurate data on extremely low fit individuals might be possible. The purpose of this study was to determine the validity of the Wahlund-Sjostrand W170 test ad...... hiện toàn bộ
Influence of exercise intensity on respiratory muscle fatigue and brachial artery blood flow during cycling exerciseSpringer Science and Business Media LLC - Tập 114 - Trang 1767-1777 - 2014

During high intensity exercise, both respiratory muscle fatigue and cardiovascular reflexes occur; however, it is not known how inactive limb blood flow is influenced. The purpose of this study was to determine the influence of moderate and high exercise intensity on respiratory muscle fatigue and inactive limb muscle and cutaneous blood flow during exercise. Twelve men cycled at 70 and 85 %

The effect of normocapnic hypoxia and the duration of exposure to hypoxia on supramaximal exercise performanceSpringer Science and Business Media LLC - Tập 66 - Trang 409-414 - 1993

Two investigations were designed that (a) evaluated the effect of the respiratory alkalosis that accompanies breathing an hypoxic (H) gas mixture and (b) examined the influence of the duration of breathing this H mixture on the subsequent performance of 45 s supramaximal dynamic exercise. In experiment 1, 12 men performed a 45-s Wingate Test (WT) on three occasions breathing a normoxic (N; 20.9% 0...... hiện toàn bộ
The sag response in human muscle contractionSpringer Science and Business Media LLC - Tập 118 - Trang 1063-1077 - 2018

We examined how muscle length and time between stimuli (inter-pulse interval, IPI) influence declines in force (sag) seen during unfused tetani in the human adductor pollicis muscle. A series of 16-pulse contractions were evoked with IPIs between 1 × and 5 × the twitch time to peak tension (TPT) at large (long muscle length) and small (short muscle length) thumb adduction angles. Unfused tetani we...... hiện toàn bộ
