In combat sports, the ability to recover from fatigue is crucial in tournament competitions. In tournaments, there can be several matches during the same day and in many sports, the finals are contested the day after the preliminary matches. Combat sports require a variety of physical attributes, in which aerobic fitness is also essential. Maximum oxygen uptake (VO2max) of 55-60 ml/kg/min has been measured on elite male wrestlers. This study investigates whether maximal oxygen uptake affects the recovery of endurance performance and the recovery of power of the neuromuscular system after intense endurance loading.\n\nMethods. Twenty (20) men who were combat sports hobbyists or competition-level athletes participated in the study. The study consisted of three test sessions for two weeks. In the first session, the VO2max and maximum aerobic power were determined in an incremental aerobic test. Intensive endurance loading was cycling to exhaustion at maximum aerobic power (AERPmax). In the second session, subjects performed three AERPmax with 15 minutes break between loadings. Before and after loadings, the performance of the neuromuscular system was assessed by measuring countermovement jump height and maximum power out-put on the isometric leg press. Oxygen uptake was measured with a gas analyzer during loadings and time was taken to measure the duration of the performance. On the third session, the day after the previous ses-sion subjects performed one AERPmax to exhaustion, and the performance measurements were repeated. Recovery variables were the difference in countermovement jump pre values between loading days (CMJE), the difference in isometric leg press maximum power pre values between loading days (MIFE), the difference between the length of the first AERPmax of the loading days (sMAXE) and difference in VO2max between the first AERPmax of the loading days (VO2maxE). All the loadings were performed with a bicycle ergometer.\n\nResults. There was no statistically significant linear relationship between any recovery variable and VO2max: CMJE (r = -0.185, p = 0.434), MIFE (r = -0.029, p = 0.905), VO2maxE (r = 0.217, p = 0.357) and sMAXE (r = -0.229, p = 0.331). Endurance performance improved on the following day with 15 of the sub-jects. Oxygen uptake of the subjects improved by 3.7 % the day after endurance loading (p = 0.0003). The maximum power output measured in the isometric leg press decreased by 5.1% (p = 0.052) the day after endurance loading.\n\nDiscussion. Based on this study aerobic capacity does not affect the recovery of combat sports practitioners for the following day from endurance loadings. However, it should be considered that the loadings did not include eccentric work that is typical in combat sports. Subjects recovered from the loadings and the endurance performance of most of the subjects improved the following day. Only the maximum power output in the isometric leg press showed signs of fatigue the day after the loading. Based on the results of the study the training of aerobic capacity should not be justified purely from the point of view of recovery. However, it should be noted that with greater aerobic capacity the same absolute endurance loading is less straining. In a combat sports match situation, a contestant with better aerobic and anaerobic capacity will be less fatigued in a situation where the straining of the contestants is the same.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2021-12-08T07:22:49Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2021-12-08T07:22:49Z (GMT).
