Muscle force has been commonly used to estimate physical function. However, muscle reaction time should not be considered for this purpose. This study evaluated the relationship between force and muscle reaction time.
The subjects are 20 university students (11 men, 9 women, whose average age is 19). Peak torque under isokinetic and concentric and eccentric contraction of the knee extensor and flexor muscles were measured by KIN-COM isokinetic dynamometer. Muscle reaction time was measured by electro myographic activity sensed by surface electrodes.
There was no relation between peak torque under any contraction styles and premotor reaction time. Also, peak torque time had the same result. However, a weak relationship was shown between peak torque and electro mechanical delay. Also, reaction time had the same result.
