The purpose of this study was to determine the influence of varying rest intervals on countermovement jump (CMJ) performances following low-intensity loaded countermovement jumps (LCMJ). Twenty-nine ...collegiate football players (age: 19.4 plus or minus 1.1 years; height: 179.0 plus or minus 5.1 cm; weight: 73.1 plus or minus 8.0) from Tuzla University volunteered to participate in the study. They performed ten LCMJs using 15% of their 1 repetition maximum squat. The subjects then executed a CMJ every 2 minutes until a total of 6 jumps had been completed. One-way repeated measures ANOVA showed significant differences in countermovement jump heights at various rest intervals, F(2.23, 62.3) = 40.5, p < 0.01, np2=.591. A Bonferroni post hoc test revealed that, the CMJs performed after 4 minutes (CMJ, standard deviation plus or minus 39.5, 4.38 cm) were superior among all pairwise comparisons after 10 LCMJs. In conclusion, the low-intensity LCMJs performed by the college football players led to the highest CMJ performances 4 minutes after the LCMJs.
