Abstract:
A study conducted with the objective to test the effect of step aerobic training for six weeks with 8 inches step platform at 126 beats per minute (BPM) on selected kinematic (Partial Temporal) variables. The study was delimited to female subjects only (N=30), age ranging from 18 to 22 years and the intensity of training set to 126 beats per minute as the protocol. The study delimited to selected kinematic (Partial Temporal) variables namely as Leg Step up, Leg Step down, Upward Arm Swing, Downward Arm Swing and Ratio Variables. The Data Recording and quantification for pre-test and post-test were administered by Video Analysis (analysis for partial temporal variables) post-test was conducted immediately after step aerobic training for 6 weeks with eight inches step platform at 126 BMP. Collected data was computed with mean, standard deviation and t-test. The selected variables for the study were Leg Step up Variable-Right (T1), Leg Step Up Variable-Left (T2), Leg Step Down Variable-Right (T3), Leg Step Down Variable-Left (T4), Leg Step up Variable-Left (T5), Leg Step Up Variable-Right (T6), Leg Step Down Variable-Left (T7), Leg Step Down Variable-Right (T8), Upward Arm Swing while performing variable T1-Variable (T9), Downward Arm Swing Variable while performing variable T2 (T10), Upward Arm Swing while performing variable T3-Variable (T11), Downward Arm Swing Variable while performing variable T4 (T12), Upward Arm Swing while performing variable T5-Variable (T13), Downward Arm Swing Variable while performing variable T6 (T14), Upward Arm Swing while performing variable T7-Variable (T15), Downward Arm Swing Variable while performing variable T8 (T16), Ratio Variables (T17-T32). It was concluded that there was significant effect of step aerobic training on the selected kinematic (Partial Temporal) variables namely as T1,T2,T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13,T14,T15,T16, T17, T18, T19, T20, T21, T22, T23, T24, T25, T26, T27, T28, T29, T30, T31 and T32 in both of the protocols. Effect of step aerobic training for six weeks in different protocol were found to be significant for biomechanical adaptation. All the selected kinematic (temporal) variables supported each other as per the existing literature or research and were found suitable for step aerobic training evaluation.
