Short-term creatine supplementation has no impact on upper-body anaerobic power in trained wrestlers

Figures & data

Fig. 1 The sequence of procedures carried out during a simulated competition day. T1–T4—upper-body intermittent sprint performance tests; BM—body mass; BL—blood sample; USG—urine specific gravity; HR_ER—early recovery heart rate; HR_LR—late recovery hear rate

Fig. 2 Peak power (a, b) and mean power (c, d) attained during upper-body intermittent sprint performance tests T1–T4 before (trial 1) and after (trial 2) 5-day supplementation period. The columns represents average ± SD peak and mean power values for six 15-s bouts of maximal effort performed during the test. In both placebo and creatine groups the number of subjects is 10

Fig. 3 Blood lactate in upper-body intermittent sprint performance (UBISP) tests T1 and T4 before (a) and after (b) 5-day supplementation period. Data are presented as means ± SD for 10 subjects in both placebo and creatine groups. Pre-Ex—immediately before UBISP test; Post-Ex—4 min after UBISP test. Significantly different (P < 0.05): * from Pre-Ex: ^# from T1
