comparing the effect of exercise with 3 iso device and traditional resistance exercises on the strength control of biceps brachii muscle of semi-professional male volleyball players

The use of modern technology has allowed athletes to train to the best of their ability and prepare for the competition. volleyball is a discipline in which speed (velocity) and accuracy play a key role. the present study aims to investigate force control by the inventive device. in this semi-experimental research, 31 volleyball players males were randomly assigned to the traditional training group (n=11), 3iso device group (n=11), and control group (n=9). one-repetition maximum of biceps brachii, an isometric maximum strength test in four angles, and a force control were tested at baseline and 8 weeks later at the study completion. right, and left-hand force control improved from baseline to post-intervention by training with 3iso device (p=0.0001), furthermore, these changes were not significant in the control and the traditional training groups. finally, the results of this study revealed that the force control produced by 3iso device is better than the traditional training, which leads to more precise and controlled movements in athletes.
