Hypothesis and Independent and Dependent variables Hypothesis: The angular velocity of the knee and linear velocity of the hip is greater in the bodyweight hip thruster than the angular velocity of the knee and linear velocity of the hip in the weighted hip thruster. As a result, the jumping height would be greater in the bodyweight hip thruster than the weighted hip thruster. Independent variables: Barbell or no barbell Dependent variables: knee and hip angles and angular and linear velocity

Initial and Final Position of Angular Velocity for knee; Bodyweight version

Calculations for Angular Velocity for Knee; Bodyweight Version Angular Velocity equals Angular Displacement over time. Angular Displacement equals final angle minus initial angle. Final angle- 158 degrees - Initial angle- 59 degrees = 99 degrees If converted to radians: 57.3 degrees in 1 radian. 99/57.3= 1.73 radians. Rounded to nearest hundredth. Time it took: .6 sec Angular Velocity= 1.73 radians/.6sec= 2.88 radians per sec

Final and Initial Positions for Linear Velocity for Hip; Bodyweight version

Calculations for Linear Velocity of Hip; Bodyweight Version Linear Velocity equals the distance traveled over time Distance traveled: 1.13m time it took: .6sec Linear velocity = 1.13m/.6sec= 1.88 meters per sec

Initial and Final Positions of Angular Velocity of Knee; Weighted Version

Calculations for angular velocity of the knee; Weighted Version Angular Velocity equals Angular Displacement over time. Angular Displacement equals final angle minus initial angle. Final: 176 degrees - Initial: 53 degrees = 123 degrees Converted to radians: 57.3 degrees in 1 radian 123/57.3= 2.15 radians; rounded to nearest hundredth Time it took: .8 sec Angular Velocity= 2.15 radians/.8 sec= 2.69 radians per sec

Final and Initial Positions for Linear Velocity of the Hip; Weighted Version

Calculations for linear velocity of the hip; Weighted version Linear Velocity equals the distance traveled over time Distance traveled: 1.39 m Time it took: .8sec Linear Velocity= 1.39 m/.8sec= 1.74 meters per sec

Results and Conclusion Angular Velocity for the knee angle; bodyweight version: 2.88 radians per sec Linear Velocity for hip angle; bodyweight version: 1.88 meters per sec Angular velocity for knee angle; weighted version: 2.69 radians per sec Linear velocity for hip angle; weighted version: 1.74 meters per sec Video recorder man reported I jumped 3 to 4 inches with weight and 5 to 6 inches without weight Because of my results, my hypothesis was proven correct. Measurements for bodyweight hip thruster was greater than weighted hip thruster causing myself to jump higher.
