Abstract:
We investigate the acute fatiguing effects of high intensity interval exercise (HIIE) on planned agility performance in 19 male (n = 9) and female (n =10) soccer players. An agility T-test was performed before (PRE), and twice following (POST 1 and POST 2) completion of four 4-sec cycle ergometer sprints. The sprint intervals were separated by 25-sec active recovery. POST 1 was performed approximately 25 sec following the final cycle sprint and POST 2 began two minutes after completing POST 1. Repeated measures ANOVA and Bonferroni post hoc tests were used to determine significant differences in the time (sec) to complete the T tests. During HIIE, the power drop measured as the difference between highest and lowest average power output achieved was 30.7 ± 9%. Time to complete the agility T-test significantly differed among the three tests (PRE: 10.46 ± .17 sec; POST 1: 11.67 ± .33 sec; POST 2: 10.96 ± .19 sec; F(2, 54) = 6.174, p = .003). Post hoc test revealed an increase in time from PRE to POST 1 (p = .002), but no difference between PRE and POST 2 (P =. 473). Nine participants (48%) were unable to complete POST 1 without errors; however, ten (52%) participants recovered well enough to perform POST 2 without error. These results show that acute fatigue from HIIE impairs planned agility, but performance can be recovered within a few minutes. Coaches can safely combine fatigue-inducing drills and planned agility training into a single session.
