Zusammenfassung
OBJECTIVES This study investigated the speed–effectiveness index (SEI) profile for running long jump in female college students and its applicability in evaluating jump skill. METHODS Sixty-two female college students were chosen as subjects. First, a multiple regression analysis was performed by setting jump distance as the dependent variable and height, weight, and 50-meter run time as independent variables. The SEI was calculated as the ratio between the actual jump distance and estimated jump distance derived by substituting the subject’s 50-meter run time into a liner regression equation correlating 50-meter run time with an actual jump distance (based on all subjects). RESULTS The only significant regression coefficient was the 50-meter run (p < .05), which accounted for 59.5% of jump distance variance. The SEI, which refers to the effective (or ineffective) use of speed in jumping distance, is considered a normally distributed jump skill metric. Furthermore, no significant differences in physique were found between high-SEI (greater than or equal to 1) and low-SEI (below 1) groups. CONCLUSIONS The SEI could provide a relative evaluation of jumping performance depending on physical resources without consideration of physique.
