Parameters Of Mean Power Related To Width Of Grip In Bench Press
Vol.6,No.2(2012)
The objectification of strength speed abilities diagnostic is very important in the field of conditioning. The studies are mostly concentrated on the activity of muscle groups, by EMG, in various ways using bench press. The main aim of research was to compare selected parameters of strength in two basic bench press grips, wide and narrow, performed on a horizontal bench. We measured the maximal mean power in total and in the acceleration part of concentric phase of movement. The results confirmed the hypothesis that the peak mean power in total concentric phase was achieved by narrow grip with counter movement 509,9±87,2 W and with wide grip 477,06±86,7 W (p<0,01). In acceleration part of concentric phase was the peak of mean power achieved in a narrow grip with counter movement 692,9±137,8 W, although in wide grip only 652,2±122,5 W (p<0,05). We recommend to use narrow grip as a means of special strength development especially in sports where kinematics of movement are similar for example bobsleigh, handball, karate, box, etc.
