Ethical approval was obtained from Physiology Labaorphysiological tests were completed in one included: Body Mass – was measured using a standard balance scale. Body Composition – was assessed using the sit and reach test. Upper Body Muscular Endurance – was measured using the push-up test. Abdominal Muscular Endurance – was measured using the partial curl-up test. Lower Back Muscular Endurance – was measured using the back extension Lower Extremity Power Aerobic Fitness – was estimated using the 20-meter multistage shuttle run test of aerobic fitness (Leger’s test) Results and Discussion sum of 5 skinfolds was 41.0 ± 12.0 mm. ticipants demonstrated “excellent” extension (161.3 ± 26.2 sec), and “very good Physiological test data. recommendations provided by Behm (2007), in which muscular endurance, trunk strength, aerobic capacity, and flexibility are factors which influence performance and should be incorporated into a training including both abdominal and lower back, appear to be for a strong lower body necessary for balance and stability during sweeping.
