Abstract

We analyzed the comparison between two pieces of equipment that evaluates leg strength. 27 girls and 18 boys (15-19 years) from the N-E area of Romania performed vertical jumps after the squat jump (SJ), countermovement jump (CMJ) and CMJ with arms swing (CMJ-AS) procedures. We used JustJump and Desmotec. There were found differences between the two devices among the values obtained from all three jumps for both boys (SJ=9.1 cm, CMJ=9.8 cm, CMJ-AS=11 cm) and girls (SJ=4.3 cm, CMJ=4.7 cm, CMJ-AS=5.5 cm). There weren't big differences between the evaluation of girls with Desmotec and boys with JustJump in all jumps. Desmotec generated considerably higher values compared to JustJump.
