Abstract
Aim of the study, was to compare among players, repetitions, and gender kinematically the subordinate leg lunges exercise (SLLE) for lower extremities with fifteen repetitions maximum (15 RM) load. The delimited variables were angle and temporal variables of SLLE. 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 SLLE 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, ‘t’ test and analysis of variance. 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). The coefficient of variance (C.V.) that is comparison among the players of each repetitions independently reflected homogeneity in respect to variable namely MKER (C.V. ranged from 5.23% to 7.63% in 15 repetitions) but heterogeneity for the remaining variables namely MKFR (C.V. ranged from 11.11% to 16.07% in 15 repetitions), TTDMR (C.V. ranged from 18.95% to 39.67% in 15 repetitions), TTUMR (C.V. ranged from 13.25% to 28.26% in 15 repetitions) and TTTR (C.V. ranged from 15.34% to 27.8% in 15 repetitions). ). Comparison between male, and female demonstrated significant differences in regards to MKFR (‘t’ = -5.706), MKER (‘t’ = -11.102), TTUMR (‘t’ = -0.659), TTTR (‘t’ = -4.630) and no difference in regard to TTDMR (‘t’ = -0.071). Analysis of variance (i.e. comparison among the repetitions) of SLLE variables namely MKFRM (F=0.045), MKERM (F=0.113), TTDMRM (F=0.487), TTUMRM (F=0.705), TTTRM (F=0.594), MKFRF (F=0.294), MKERF (F=0.511), TTDMRF (F=0.605), TTUMRF (F=0.263) and TTTRF (F=0.165) were statistically insignificant at 0.05 level of significance. From the findings, it is concluded that the comparison (C.V.) among the players demonstrated homogeneity in regard to angle variable namely MKER but heterogeneity for the remaining angle and temporal variables namely MKFR, TTDMR, TTUMR and TTTR. There was gender difference in regard to angle and temporal variables namely MKFR, MKER, TTUMR, TTTR and no difference in regard to temporal variable namely TTDMR. From the analysis of variance it is concluded that SLLE are consistent for 15 repetitions in regard to all the selected variables.
