The purpose of this study was to quantify the components of acceleration, load range and deceleration through a velocity spectrum during concentric hip abduction and adduction isokinetic exercise, and to investigate the effect of load range on peak torque and work done. 16 male healthy subjects performed 3 maximal concentric reciprocal hip abduction and adduction gravity corrected repetitions in a fixed order at 60, 120, 180, 240, 300, 360 and 420 degrees . s(-1), with a 30 s rest between velocities. Hip abduction and adduction results revealed that load range significantly decreased while acceleration and deceleration ROM significantly increased (p < 0.05) with each increase in velocity. When the total peak torque data was corrected for load range there was a significant decrease (p < 0.05) in peak torque at velocities of 300 degrees . s(-1) and above, for both hip abduction and adduction. Load range correction also resulted in a significant decrease (p < 0.05) in work done at velocities of 120 degrees . s(-1) and above, for both hip abduction and adduction. The results demonstrate an inverse relationship between isokinetic velocity and load range during concentric hip abduction and adduction, and suggest a need for the clinician to carefully consider velocity selection when performing exercise on an isokinetic device.
