The purpose of this study was to compare the effect of broad jump (BJ) on leg motor fitness on male undergraduates of Czech Republic (CZE) and Nigeria (NG). Leg muscular endurance (LME), leg power (LP) and speed (Sp) were selected as leg motor fitness variables. The nonrandom selection, pre-test post-test experimental design was adopted for this study. Forty-eight participants were purposively selected, and these were drawn from Masaryk University of CZE (n = 24, age = 20.63 ± 1.50 yrs, height: 183.38 ± 6.58 cm, weight: 78.56 ± 7.38 kg) and University of Calabar of NG (n = 24, age = 22.75 ± 3.04 yrs, height: 173.37 ± 7.96 cm, weight: 62.83 ± 7.38 kg), and randomized separately in each country into BJ (n = 12), and control (n = 12). Training protocol was 4 seconds work, 5 seconds rest between works, 10 repetitions, 8 sets, 2 min between sets, totaling 30 min including warm-up and cool-down, twice per week for 8 weeks. Participants in CZE were measured using isotonic-squat with weight for LME, Myotest Pro for LP, and 10m dash using timing gate for Sp. While participants in Ng were measured using isotonic-squat with weight for LME, Sergeant Jump for LP, and 10m dash with stopwatch for Sp. MANCOVA was used to test the hypotheses at p<.05 and multiple bar graph for the research question. The findings showed that CZE BJ had a significant effect on LME and Sp with effect size (ES) 24.2% and 39.0% respectively, and NG BJ had a significant effect on LME with ES 31.0%. BJ was effective in both countries, but with higher ES in CZE. However, LP was higher in ES of DJ in NG. The differences in previous experiences and the settings of both countries may had contributed to the differences in the result.
