Abstract
TSUJI, I., NAGASAKI, H. and NAKAMURA, R. Motor Time of the Rectus Femoris under Loading of Different Weights. Tohoku J. exp. Med., 1985, 146 (1), 119-120 -Motor time (MT) of the rectus femoris was measured for seven normal subjects during rapid extension of the knee joint at 60° flexion in the sitting position with and without external loads on the leg. MT prolonged linearly with external load from 0 to 4kg. Tangent of this linearity, the rate of tension development (RTD), was significantly different from one another of the subjects and was not related to MT without external load. RTD is a relevant index to assess an efficiency of rapid force generation of a muscle.
