RESUMO

Slamet Widodo, Rumi Iqbal Doewes

Leg muscle power supports the motor action of playing futsal for both the goalkeeper and field player. The squat jump is one of the tests for lower-body strength. The research purpose was analyzed the difference in squat jump performance between goalkeeper and field futsal players. The research sample consisted of 12 male futsal athletes (mean 19.50 ± 0.52 years, 59.17 ± 7.30 kg, and 166.17 ± 5.64 cm). Independent t test was used to determine the difference in jump height between the two playing positions. Multiple linear regression test was used to show the contribution of the kinematics parameters and squat jump kinetics to the squat jump height. The results showed that the squat jump performance was 49.00 ± 1.55 cm for the goalkeeper and 46.33 ± 1.37 cm for the field player. Independent t test shown a significant difference in the jump height of the two playing positions with a jump height difference of 2.67 cm higher for the goalkeeper (p-value = 0.01). Multiple linear regression test showed that the kinetic parameters, namely power, work, and force contributed 97.7% to the difference in jump height in the two playing positions. So it can be concluded that to produce a high jump requires power, work, and force
