Abstract:
The purpose of this study was to investigate the movement speed characteristics of 2 intrinsically different limbs. Twenty subjects volunteered to participate (10 men and 10 women). Each subject performed 5 repetitions of concentric knee and elbow extension and flexion movements at 60 through 500 d.s(-1) on an isokinetic dynamometer. Kinematic data were collected at 1,000 Hz and separated into rate of velocity development (RVD) and peak torque. Results demonstrated a significant (p < 0.05) main effect for sex for RVD and peak torque. Significant (p < 0.05) differences were also demonstrated between knee and elbow RVD and between knee and elbow peak torque at every speed tested. Neither knee and elbow RVD nor peak torque demonstrated any significant Pearson correlations at any speed tested (r = -0.17-0.41). These results collectively point to the specificity of limb speed and torque as a result of biophysical differences such as length and mass. Therefore, strength and speed may be modulated by neuromotor patterns that differ based on individual limbs.

When an external force is exerted, it sets the crank into a rotational movement. This, in turn, instigates the motion of the connecting rod, leading to what is referred to as a general plane motion. This process involves two key points - point A on the connecting rod...
