Relationship between long jump performance and approach run velocity and take-off velocity using simple measurement method

Abstract

    The aims of this study were to investigate the relationships between long jump records and mean velocities in two 5-meters sections during approach running (12-7m and 7-2m sections from the point of take-off), between records and horizontal velocities and vertical velocities after take-off, and between records and the loss of horizontal velocities at take-off, and to obtain some suggestions for coaching toward the long jumpers.
    The motions of 66 long jumpers (35 male and 31 female) were filmed and then approach running and take-off velocities were analyzed.
    The records had positively related to approach running velocities of both sections. We found that records were positively related to not only horizontal velocities but also vertical velocities after take-off. While, losses of horizontal velocities at take-off were negatively related to record. These results suggest that better long jumpers have higher running velocities from beginning of running approach, higher horizontal and vertical velocities, and lower loss of velocities at take-off.
