Abstract

Objective: Proving optimal angle of hip and knee for obtaining the greatest force and maximum jump height when vertical jump motion with Countermovement Jump (CMJ) technique. Design: This research is an observational analytic study with cross sectional study design.Methods : There are 17 volleyball athletes who meet the inclusion criteria and are not included in the exclusion criteria. A total of 17 subjects were observed knee flexion angle, hip flexion angle, Ground Reaction Forces (GRF) and high jump in gait analysis room at Medical Rehabilitation Installation RSUD Dr.Soetomo. All the study samples performed a jumping motion with a countermovement jump technique three times, and the data was extracted from the highest jump value. Results : From the observation of 17 subjects by doing 3 jumps, the analysis was taken from the highest jumping value with mean of 64,34±9,51 cm, knee angle size at 104,91±16,35 degree propulsion, knee angle at take-off 42.97 ± 9.06 degrees, downward knee angle 16.26±6.48 degrees, knee angle during deceleration 66.07±8.25 degrees, pelvic angle at propulsion 102.95±16.57 degrees, hip angle take-off time of 30.29±9.96 degrees, downward angle of the pelvis 8.36±8.04 degrees, pelvic angle as deceleration 30.46±13.16 degrees, ground reaction forces (GRF) at propulsion 1414.82±203.31 Newton, GRF at take-off 327,24±235,73 Newton, GRF at downward 1567,35±244,49 Newton, and GRF value as deceleration 1298,65± 247,15 Newton. Conclusion : There is no relationship between the knee angle and the jump height but there is a relationship between the angle of the pelvis with the jump height during propulsion.There is a relationship between the angle of the knee and the angle of the pelvis with a jumping height during the take-off phase.There is a relationship between the angle of the pelvis with the jump height but there is no relationship between knee angle with high jump in the downward phase.There is no relationship between the angle of the knee and the hip angle with the leap height in the deceleration phase.There is a relationship between the Value of Ground Reaction Forces (GRF) with a high jump during propulsion.There is no relationship between Ground Reaction Forces (GRF) values with high jumps at take-off.There is no relationship between Ground Reaction Forces (GRF) with a high jump in the downward phase.There is no relationship between GRF value and leap height in the deceleration phase.
