Electromyographic activity of triceps surae muscles during human locomotion at various slopes
Several studies have reported data for human walking at various slope angles (Tohuhiro et al., 1985; Redfern et al, 1997), but few present data at steeper slope conditions both up and down. In experiments using animal models, for example, having cats walk at slope conditions between 100% upslope and 100% downslope, it was reported that ankle extensor muscles displayed different behaviors during...
متن کاملThree-Dimensional Ankle Moments and Nonlinear Summation of Rat Triceps Surae Muscles
The Achilles tendon and epimuscular connective tissues mechanically link the triceps surae muscles. These pathways may cause joint moments exerted by each muscle individually not to sum linearly, both in magnitude and direction. The aims were (i) to assess effects of sagittal plane ankle angle (varied between 150° and 70°) on isometric ankle moments, in both magnitude and direction, exerted by ...
متن کاملInhibition of electromyographic activity in human triceps surae muscles during sinusoidal rotation of the foot.
Torque and electromyographic (EMG) responses to sinusoidal rotations of the foot were measured. The frequency range of the movements was 0.5 Hz to 15 Hz at amplitudes ranging between 1 and 10 degrees. At frequencies above 7 Hz, the EMG activity did not follow individual foot rotation cycles. The EMG activity was inhibited whenever the peak torque was large with respect to the first cycle peak ...
متن کاملMuscle activation and its distribution within human triceps surae muscles.
The purposes of this study were 1) to quantify the volume of activated parts within a whole muscle and 2) to examine activated area distributions along the length of muscle. Seven male subjects performed five sets of 10 repetitions of a single-leg calf-raise exercise with the knee fully extended. Transverse relaxation time (T2)-weighted spin echo images were acquired before and immediately afte...
متن کاملTriceps Surae Short Latency Stretch Reflexes Contribute to Ankle Stiffness Regulation during Human Running
During human running, short latency stretch reflexes (SLRs) are elicited in the triceps surae muscles, but the function of these responses is still a matter of controversy. As the SLR is primarily mediated by Ia afferent nerve fibres, various methods have been used to examine SLR function by selectively blocking the Ia pathway in seated, standing and walking paradigms, but stretch reflex functi...
