Background: The aim of the present research was to study the psychological and physiological features associated with aerobic and anaerobic performance in trained swimmers. Methods: A correlation and stepwise regression analyses were conducted with the data obtained in a RESTQ-76 sport questionnaire, a heart rate variability test, and an anaerobic and aerobic swimming performance efforts of 20 swimmers. Results: Aerobic performance correlated, principally, with parameters related to parasympathetic modulation measured in the frequency and time domains of the heart rate variability (LF/HF r: −0.806, p < 0.001; NN50 r: 0.937, p < 0.001). Swimmers’ anaerobic performance correlated to psychological features (low stress r: 0.526, p: 0.025, and high fatigue r: −0.506, p: 0.032). Conclusion: Swimming performance presented different psychological and physiological features depending on the probe characteristic. Specifically, swimmers’ anaerobic performance was associated with psychological features (low stress and high fatigue perception) and aerobic performance with physiological features (high parasympathetic modulation). This information could help coaches to know the variables to control in their swimmers, depending on the probe in which they compete (anaerobic or aerobic).

Background. Probably L-Carnitine can induce the increase of Pyruvate dehydrogenase activity, decrease of lactic acid production and performance improvements due to the reinforcement of long chain fatty acid oxidation and stabilize of coASH to free COA. Based on this, the aim of our study was to investigate the effects of acute L-Carnitine supplementation on blood lactate, glucose, VO 2 max and anaerobic power in elite male artistic gymnasts. Methods. Eighteen male artistic gymnasts were randomly assigned to supplementation (n = 9) or placebo (n = 9) groups. In a double blind design, subjects participated in two tests with a break of one week between them. Subjects ingested 3 grams of L-Carnitine or placebo (maltodextrin) 90 minutes before aerobic and anaerobic exercise protocols. We used a 20 m shuttle run as an aerobic exercise protocol and running based anaerobic sprint test (RAST) as an anaerobic exercise protocol. Blood samples were collected 5 minutes pre and 4 minutes post-tests for the analysis of lactate and glucose. Results. L-Carnitine group had significantly lower lactate concentration than placebo group after tests (p < .05). L-Carnitine group had significantly higher blood glucose (p < .05) compared with placebo group, too. Also VO 2 max as well as mean and maximum power in L-Carnitine group were significantly higher than those in placebo group (p < .05). Conclusions. These findings indicated that acute oral supplementation of L-Carnitine can probably induce fatigue decrease and improvement of aerobic and anaerobic performance in elite male artistic gymnasts.

Purpose: The aim of this study was to investigate the effects of two-week high intensity interval training (HIIT) on aerobic and anaerobic performance of kick boxers. Material: 24 male kick boxers (age 19.39 ± 0.72 y, body mass 74.14 ± 6.22 kg, height 177.95 ± 5.29 cm) volunteered for the study. Participants were randomly divided into two groups: experimental and control. As well as routine training program, experimental group carried out Wingate-based HIIT 3 times per week for two weeks. Wingate protocol was as follow: 4 repetitions with 4 mins recovery (4X30sn all-out effort) during the first week, 5 repetitions with 4 mins recovery (5X30sn all-out effort) during the second week. In order to determine aerobic capacity, 20m shuttle run test was used while Wingate anaerobic test was used to determine anaerobic performance. Descriptive statistic was used to demonstrate mean values and standard deviation of the variables. Non-parametric Mann Whitney-U test was used to show the differences between groups. Wilcoxon Signed Rank Test was used to compare intra-groups results from pre and post-test applications. Results: There was no significant difference between groups during pre-test measurements There was significant difference in PP, MP in experimental group compared to control during the post-test measurements. There was no difference in body mass, body fat (%) and predicted VO2max in both groups between measurements. Conclusions: According to intra and inter-group results, it can be concluded that two-week Wingate-based HIIT can be used to improve aerobic and anaerobic performances of kick boxers.
