| Popis: | Objetive The acute effects of cryotherapy on creatine phosphokinase (CPK) and lactate dehydrogenase (LDH) expression, perceived pain and upper limb muscle strength in jiu-jitsu competitors were investigated. Method Ten highly trained athletes underwent two simulated competition sessions composed by four 7-minute combats with a 15-minute interval between them. Athletes were randomly allocated to receive either cold water immersion (5 ± 1 °C for 19 minutes) or no intervention (control) after competition simulation in a crossover counterbalanced fashion. Results For LDH, there was an effect of condition (F 1,18 = 7.91, P = 0.012; η 2 = 0.31), with lower values being found in cryotherapy as compared to control (criotherapy = 533.2 ± 55.4 and 671.2 ± 61.0 for pre-competition and post-recuperation, respectively; control = 528.5 ± 63.7 e 759.8 ± 85.7 UI/l for pre-competition and post-recuperation, respectively). Delta CPK differed significantly between conditions (criotherapy = 138.0 ± 95.1 UI/l; control = 231.3 ± 135.8 UI/l t = -1,72; P = 0,119; effect size = 0.75). For perceived pain there was also an effect of condition (F 1,18 = 12.35, P = 0.003; η 2 = 0.41), with lower values being found following cryotherapy (2.4 ± 1.4 versus 4.4 ± 1.8, P = 0.003). Pre-competition skin temperature was lower than that measured after recovery (34.5 ± 1.9 °C. versus 37.6 ± 1.3 °C, P = 0.0005). There were significant correlations between perceived pain and CPK (r = 0.314) and LDH (r = 0.546). The concentrations of CPK and LDH were negatively correlated with dynamic strength (r = 0.525). Conclusion Recovery via cold water immersion after simulated competition resulted in less muscle damage and hypoalgesia compared to the control. |
