The purpose of this investigation was to determine the relationships between the strength qualities of the leg extensor musculature and performance in vertical jumps (VJ) performed from a standing position and a run-up. Methods. Twenty-nine male with experience in jumping activ- Ities were tested for vertical jumping capacities with a standing VJ (double leg takeoff) and run-up jumps from a 1,3,5 and 7 stride approach (single leg takeoff).
