Summary: This study describes the physiological and psychophysical responses of elite female rugby sevens athletes to a short-term heat acclimatization training camp. The results showed that exercising heart rate and sweat rate decreased during the camp, and thermal sensation also decreased. However, changes in resting core temperature, rating of perceived exertion, and thermal comfort were unclear.

Summary: The research suggests that reinforcement learning relies on prediction errors to quantify the difference between obtained and expected rewards. Different corticostriatal circuits are activated for positive and negative prediction errors. A recent study on university students found that beliefs about grade expectations are more likely to be updated following positive prediction errors.

Summary: The study shows that the real-world average CO2 emissions of PHEVs vary depending on factors such as all-electric range, user group, and country. For private vehicles, the real-world CO2 emissions are significantly higher than test cycle values, mainly due to low charging frequency.

Summary: This study aimed to compare the impact of hot-humid environmental conditions on performance outcomes, thermoregulatory responses, and thermal perception during exercise between elite para- and able-bodied athletes. The results showed that both groups experienced similar performance losses in hot-humid conditions, but para-athletes had lower increases in gastrointestinal temperature. Individual variation within both groups suggests the importance of personalized heat mitigation plans.

Summary: This study aims to investigate the lifestyle of Iranian elite athletes. It utilized a qualitative research approach in two phases, employing Glaserian grounded theory and thematic analysis. The findings revealed multiple indicators of the Iranian elite athletes' lifestyles, which could be categorized into different dominant lifestyles.

Summary: This study presents a real-world HAR open dataset compiled from a wristband equipped with an accelerometer. A general convolutional neural network model trained on this dataset achieves an MBA of 80%. Personalizing the general model through transfer learning improves the MBA to 85% using fewer data. The paper demonstrates the potential of transfer learning in making HAR models trained in different contexts perform well for new individuals with limited real-world labeled data available.

Summary: The COVID-19 pandemic poses challenges for sports medicine teams to safely transition elite athletes back into sports after infection. Athletes must isolate and undergo cardiac tests before gradually reintegrating into training according to a return-to-play plan.

Summary: The purpose of this study was to investigate the effects of a training camp with heat and/or hypoxia sessions on hematological and thermoregulatory adaptations. The results showed that blood and plasma volume increased following the camp. However, sleeping at altitude impeded the increase in hemoglobin mass and only marginally increased it when training in the heat.

Summary: Experimental psychology's shift toward low-effort, high-volume methods raises concerns about ecological validity. To address these concerns, relief registries are introduced as a method to investigate altruistic behavior. This method allows research subjects to choose and directly donate highly needed items to charitable organizations using existing online gift registry platforms, balancing internal validity, ecological validity, and ease of implementation.

Summary: This study examined the concerns and beliefs of Olympians and elite athletes towards COVID-19 vaccination. A survey was conducted among 895 Polish elite athletes representing 34 sports. The results showed that 76.3% of the athletes were vaccinated, with women and Olympic participants being more likely to receive the vaccine. Athletes expressed concerns about the impact of COVID-19 on their training and long-term health. Vaccinated athletes showed higher confidence in the vaccine composition and doctors' recommendation. Athletes competing at the Olympic level were less likely to doubt the speed and testing of the vaccines. National-level athletes exhibited the highest level of distrust towards the government and doctors regarding COVID-19 vaccination.

Summary: The study found that high endurance elite athletes have lower levels of circulating C2, C3b/iC3b, and adipsin, which are associated with lower inflammatory, oxidative stress, and cellular aging markers. These complements were positively correlated with most other detected complements, pro-inflammatory cytokines, and antioxidant enzymes, but negatively correlated with telomere length in younger elite athletes. High endurance elite athletes also showed lower concentrations of 10 other complements in younger athletes compared to older counterparts.
