Abstract: This research examined time-related changes in movement mechanics of the lower extremity and performance during a soccer match simulation individualized to the subject's fitness level. Twenty-four elite amateur soccer players (12 males and 12 females) participated in two testing sessions. The first test session consisted of subjects performing the Yo-Yo Intermittent Recovery Test Level 1(YYIR1) that was used to prescribe the five sub-maximal running intensities for the soccer match simulation performed during test session two. The average distance run during the YYIR1 test was 1780 ±619.23 meters resulting in a match simulation running distance of 10165.52 ±1001.69 meters. Analysis of the progressive change during the soccer match simulation revealed time-related increases and changes in the rate of increase in RPE, and performance decrements across halves in sprinting, and dominant and non-dominant limb cutting with soccer match simulation duration. In contrast, a lack of significant time-related change was observed for squat jump, modified counter movement jump height, and lower extremity vertical stiffness and impedance in both the dominant and non-dominant limbs during a complex jumping task. The primary findings are that an individualized soccer match simulation prescribed using YYIR1 performance successfully replicates the demands of a soccer match, and resulted in time-related increases in RPE accompanied by decrements in sprinting and cutting speed with increasing match simulation duration. The lack of time-related change in jump performance and movement mechanics demonstrates the need for further analyses of the execution of complex tasks and the modulation of lower extremity coordination that allowed for maintenance of performance and movement mechanics during soccer match simulated exercise.
