... muscle temperature on the isometric contractile properties of electrically stimulated paralysed quadriceps muscles. When muscle temperature at a depth of 3 cm was increased from ∼32 °C to ∼36 °C by ultra-short-wave application, the half-relaxation time shortened and low-frequency force responses became...

...B. Bigland-Ritchie; D. A. Jones; G. P. Hosking; R. H. T. Edwards 1. The fatigue of force that occurs during the first 60 s of a maximum voluntary contraction of the human quadriceps has been examined by comparing the voluntary force with that obtained by brief tetanic stimulation at 50 Hz in nine...
