Summary: The study aimed to determine the effects of different set configurations on strength and muscular performance adaptations in powerlifters. Cluster sets were found to induce adaptive changes favoring impulsive activities in powerlifters, with greater increases in upper and lower body impulsive activities compared to traditional sets.

Summary: Exercise can affect the endocrine system and hormone concentrations in the body. This study investigated the hormonal response in men who do endurance-training and strength-training exercises after acute exercises compared to a non-training group. The study found no significant differences in testosterone and cortisol changes between the training and non-training groups, suggesting that the exercise volume may have been too low to elicit a reaction.

Summary: The aim of this study was to analyze the salivary proteome and metabolome of highly trained female and male young basketball players, and to identify common and different traits. The study included 20 male and female basketball players and 20 sedentary control subjects. The athletes exercised intensely and regularly, while the controls were not physically active. The results showed variations in protein expression and metabolite levels between the groups, and identified inflammation-related proteins and increased amino acids in trained athletes. The study highlights the use of saliva as a valuable biofluid to assess athlete performance and reveals both common features and sex-specific behaviors in adaptation to exercise.

Summary: This study aimed to investigate the effects of altering lactate content in saliva samples on the activity of a multi-enzyme. The enzymatic bioassay showed good linearity to lactate in the range tested and exhibited a good correlation with the colorimetric method. The proposed multi-enzyme system could be a useful tool for rapid and accurate monitoring of lactate in saliva.

Summary: This study investigated the protective effects of strength training against ethanol-induced prostatic metabolism disorders in rats. Strength training reduced alcohol consumption, increased glucose and serum lipid levels, and decreased hormonal levels. Protein expression analysis showed significant differences in hormone receptors and cell regulation between ethanol-exposed and strength training groups, suggesting strength training as a potential therapeutic strategy for ethanol-induced prostate injuries.

Summary: This study systematically reviewed the effects of plyometric jump training (PJT) on balance measures, finding significant small effects on overall, dynamic, and static balance. Sex and age do not moderate balance outcomes. PJT shows similar effects on balance improvement compared to other training types such as balance training.

Summary: A systematic review and meta-analysis examined the effect of exercise training on fasting gastrointestinal appetite hormones in adults with overweight and obesity. The review included nine studies and found that exercise training did not affect fasting concentrations of total ghrelin, acylated ghrelin, and peptide YY. However, exercise did lead to a significant reduction in body mass and BMI. Therefore, appetite and energy intake in individuals with overweight and obesity participating in exercise programs are unlikely to be influenced by fasting concentrations of gastrointestinal appetite hormones.

Summary: Women have specific physiological characteristics influenced by sex hormones and the menstrual cycle, which have complex bidirectional relationships with exercise and nutritional intake. Individualized interventions are necessary as the effects of menstrual cycle phases on exercise and nutrition vary greatly between individuals, making average data irrelevant and potentially misleading.

Summary: Even in the 21st century, female participants are underrepresented in human physiology research due to the perception that including them is more time consuming, less convenient, and more expensive. However, considering the importance of gonadal hormone fluctuations in governing vascular function and the potential misinterpretation of cardiovascular biomarkers, it is necessary for cardiovascular researchers to include females and accurately track their hormone changes. Saliva-derived measures of gonadal hormones provide a simple and noninvasive method for monitoring, which may facilitate the inclusion of females in cardiovascular research studies.

Summary: This study compared the effects of complex training (CPX), heavy strength training (HST), and endurance-strength training (EST) combined with running endurance training on neuromuscular adaptations and running performance in recreational marathoners. The results showed that CPX and HST groups improved running economy and vVO2max, as well as neuromuscular performance indicators, with greater improvements in eccentric strength and running economy compared to EST group.

Summary: This study compared the effects of a novel soccer-specific mental fatigue-inducing task with the traditional Stroop task and found that induced mental fatigue negatively affected soccer skill performance. This emphasizes the importance of avoiding prolonged and cognitively demanding skill training before training sessions and matches to prevent negative effects on performance.

Summary: This study examined the physiological and perceptional responses to different modes of shuttle running. The results showed that the directional mode had significant effects on heart rate, oxygen uptake, blood lactate concentration, and perceived exertion. Lateral shuttle running elicited the highest responses, while forward shuttle running had the lowest responses.

Summary: The study found that children with mental, behavioral, and developmental disorders (MBDDs) were less likely to meet 24-hour movement guidelines compared to children without MBDDs. Among children aged 12-17 years, the difference in proportion of meeting physical activity and screen time guidelines was larger for children with MBDDs. Additionally, ethnic minority children had a smaller difference in meeting physical activity guidelines compared to white children.

Summary: This study found that exposure to green space and engaging in sufficient physical activity are protective factors against low muscle strength in Chinese adults. The combination of increased green space exposure and physical activity may have a greater effect on improving muscle strength. Therefore, incorporating green spaces into city design and built environments is recommended.

Summary: This narrative review paper discusses the applications of machine learning in soccer, specifically focusing on injury risk assessment. It also provides practical tips for health and performance staff in soccer clubs on leveraging machine learning for a competitive advantage. While performance analysis is the most researched area, other domains such as injury risk assessment, workload monitoring, movement analysis, career trajectory, club performance, and match attendance also utilize machine learning. However, machine learning currently lacks high predictive ability for injuries but can help identify early signs of elevated risk. Future research should consider the dynamic nature of musculoskeletal injuries for more meaningful results.

Summary: This study aimed to compare the physiological and perceptual responses during moderate intensity exercise with different levels of blood flow restriction (BFR) and high intensity exercise without BFR. The results showed that regardless of pressure, exercise with BFR led to increased heart rate, blood lactate levels, and perceived exertion, while tissue oxygen saturation decreased. Furthermore, the physiological responses induced by different levels of BFR during moderate intensity exercise were similar.
