dc.description.abstract The purpose of this project was to assess the coordination and performance of the jump squat movement for multiple loading conditions. Seventeen male subjects between 18 and 30 years of age, performed two jump squats for each loading condition, 0-60% of their one repetition maximum (1 RM) incremented by 10% for each trial. Video capture was used to assess kinematics and a force platform in combination with a linear position transducer was used to determine power. All of the peak power values occurred between 0% and 30% of 1 RM and there was an overall linear decrease in power output from 0-60% (p = 0.000). The shank-thigh and thigh-trunk mean absolute relative phase (MARP) values were shown to have linear increases from 0-60%, with p-values of 0.003 and 0.014 respectively. The MARP values calculated from 0-30% were significantly different than those at 60% for both segmental relationships. These results indicate that optimal jump squat performance occurs from 0-30% of 1 RM.
