Summary: Mild endurance exercise can compensate for declined muscle quality and have a positive impact on the brain under energy restriction conditions. This impact may be related to the levels of associated factors such as BHB, BCAA, and T3.

Summary: Increasing the intensity and/or duration of aerobic training sessions improved thermoregulatory responses in rats exercising in temperate environments, but had no significant effects in warm environments.

Summary: The study aims to investigate the role of the central dopamine system in exercise capacity during adolescence, finding that dopamine receptor antagonists affect the locomotor performance of adolescent rats. Moreover, the activation of striatal D1 and extra-striatal D2 receptors is mechanistically linked to the level of exercise performance.

Summary: This study analyzed the changes in oxygen metabolism, acid-base status, and electrolytes in well-trained cyclists during the off-season. The results showed an increase in oxygen saturation and oxyhemoglobin, a decrease in fat oxidation, and a decrease in VO2 at the ventilatory threshold 2 and maximum oxygen consumption. Negative correlations were found between the changes in fat oxidation and bicarbonate ion, as well as between the changes in functional power threshold and VO2MAX with pH levels.

Summary: This study investigates the effects of supplementation with BCAAs, L-citrulline, and A-GPC on exercise performance, and finds that this combination improves cycling performance. It may be beneficial for individuals looking to enhance athletic performance, particularly in disciplines requiring lower body muscular strength and endurance.

Summary: This study investigates the effects of endurance stimuli intensity on the adaptation in strength and endurance following concurrent training, as well as the impact of training status on the acute molecular response to concurrent exercise. The results indicate that the intensity of endurance activity does not affect performance outcomes after concurrent training, and training status has no effect on the molecular responses assessed.

Summary: This study investigated the effects of intensified training on cognitive function, psychological state, and performance in trained cyclists. The findings showed that two weeks of intensified training resulted in overreaching, as demonstrated by decreased peak and mean power output, increased total mood disturbance, and disruption to recovery-stress balance. However, cognitive function remained unaffected during the training period, suggesting caution in using it as an early indicator of overreaching.

Summary: In male endurance athletes, the oxidation of PHY reaches a plateau during prolonged exercise, with the peak oxidation occurring in the final 30 minutes. The ingestion of PHY also affects blood glucose levels during exercise.

Summary: This study compared the effects of running and cycling on energy cost when matched for duration and relative intensity. The results showed that cycling significantly increased energy cost at mid and end of exercise, while running did not show any changes in energy cost throughout the duration. Changes in energy cost during cycling were correlated with muscle fatigue and changes in cadence.

Summary: The study aimed to evaluate the effect of head pre-cooling on the 5-km time-trial performance of amateur runners in the heat. Results showed that a 20-minute head cooling intervention improved 5-km running performance in a hot environment, suggesting it could be a practical pre-cooling strategy for both professional and amateur runners.

Summary: The study tested whether supplementing hydroxytyrosol, the main polyphenol in olive oil, during exercise would modify the molecular regulators of glucose uptake. Results showed that a low-to-moderate dose of hydroxytyrosol might alter the beneficial effect of training on basal AKT phosphorylation and Rac1 activity in rats.

Summary: This study found that MEP significantly increased after anodal transcranial direct current stimulation (a-tDCS), but no significant changes were found in the RPE-clamp or TT tests. This lack of improvement may be attributed to RPE being more controlled by afferent feedback during TT tests than during TTF tests.

Summary: Exercise can affect the levels of vitamin D metabolites in circulation. Endurance exercise can increase serum 25(OH)D levels, but has limited effect on serum 1,25(OH)(2)D levels. Exercise may influence 25(OH)D levels in the circulation by regulating the storage of vitamin D metabolites in tissues or their utilization by target tissues. The effects of exercise on 25(OH)D levels may be dependent on factors such as vitamin D nutritional status, exercise type and intensity, and sex. Further research is needed to investigate the effects and mechanisms of exercise on vitamin D metabolites.
