Comparison and Correlation of Maximum Vertical Ground Reaction Force, Accumulate iEMG, Average iEMG and MPF Depend on Preliminary Jump Type
[PURPOSE] The purpose of this study was to compare on maximum vertical ground reaction force(MVGRF), accumulate iEMG, average iEMG, and MPF depend on preliminary 3 type jump, and to analyze the correlation among vertical ground reaction force and muscle activities, and to provide information for effective vertical jump. [METHODS] The subjects were consisted of 9 college men without knee pain or medical history. The preliminary jump was consisted 40cm drop jump, Sargent jump and double jump. The arm was crossed in front of chest to avoid the effects of upper arm. The maximum vertical ground reaction force, and accumulate iEMG, average iEMG, and MPF on right side 5 muscles during preliminary 3 type jump were measured. [RESULTS] The MVGRF was significantly different among preliminary 3 type jump(p<.01), followed by drop jump, double jump, and Sargent jump. In cumulative iEMG, there was a significant difference on tibialis anterior and gastrocnemius muscles, and cumulative iEMG of vastus lateralis, biceps femoris, and gastrocnemius were in the order of drop jump, double jump, and Sargent jump similar with MVGRF. In average iEMG, there was a significant difference in biceps femoris, and gastrocnemius (p<.05, p<.01), and average iEMG of vastus lateralis, and gastrocnemius were similar with MVGRF. In MPF, there were significant differences in biceps femoris, and gastrocnemius (p<.05). In all of the five muscles, the order of the Sargent jump, double jump, and drop jump was different from MVGRF. [CONCLUSIONS] There was no significant correlation between the MVGRF, cumulative iEMG and average iEMG of the five muscles according to preliminary 3 type jump. According to preliminary jump type, the number of positive correlated muscles varied from 5 to 0, and the muscles with the highest correlation were also different.
