Abstract:
The aim of this study was to describe kinematically the hamstring curl exercise (HCE) for lower extremities with fifteen repetitions maximum (15 RM) load. The delimited variables were temporal variables and angle variables of HCE. The study was conducted on ten subjects (five male and five female), weight of the subject was 68.1±14.98 kilogram and age ranged from 17 to 25 years. Each subject had performed HCE with 15 RM load for 15 repetition. Data was collected using two dimensional digital video recording systems for 2D analysis (Kinovea 0.8.21). Collected data was computed with mean, standard deviation, coefficient of variance and analysis of variance. The selected variables for the study were Maximum Knee Flexion Repetition Wise (MKFR), Maximum Knee Extension Repetition Wise (MKER), Time Taken for Downward Movement Repetition Wise (TTDMR), Time Taken for Upward Movement Repetition Wise (TTUMR) and Total Time Taken Repetition Wise (TTTR). Analysis of variance (i.e. comparison among the repetitions) of HCE variables namely MKFRM (F=0.425), MKERM (F=0.155), TTDMRM (F=1.154), TTUMRM (F=0.705), TTTRM (F=0.594), MKFRF (F=0.176), MKERF (F=0.479), TTDMRF (F=0.328), TTUMRF (F=0.263) and TTTRF (F=0.165) were statistically insignificant at 0.05 level. In the conducted study the coefficient of variance (C.V.) equal to or more than ten percent considered as heterogeneous otherwise homogeneous. The coefficient of variance (C.V.) that is comparison among the players of each repetitions independently reflected homogeneity in respect to variable namely MKER but heterogeneity for the remaining variables namely MKFR, TTDMR, TTUMR, and TTTR. It is concluded that HCE are consistent for 15 repetitions. The comparison (C.V.) among the players demonstrated homogeneity in regard to angle variable namely MKER (C.V. =7.45%) but heterogeneity for the remaining angle and temporal variables namely MKFR (C.V. =13.04%), TTDMR (C.V. =42.03%), TTUMR (C.V. =42.05%), and TTTR (C.V. =39.06%).
