Summary: This systematic review examines the applications of Electrical Impedance Myography (EIM) in health and physical exercise, including studies on muscle characterization, changes in injured soccer players, and adaptations to physical exercise. EIM has shown promise in evaluating muscle conditions, especially in neuromuscular diseases, and has potential as a cost-effective alternative to methods like MRI, but further research and standardization of protocols are needed for its broader adoption in the scientific field.

Summary: Performance is influenced by both physical and psychological factors, with empathy playing a potential role in individual and team performance. Possible mechanisms related to mirror neurons or the affordance competition hypothesis may be at play. The impact of empathy on performance can be moderated by factors such as sex, age, and culture.

Summary: This narrative review examines the impact of gender-affirming hormone therapy (GAHT) on the physical performance of transgender people in elite sport. The review finds that within 3 years of testosterone therapy, nonathletic trans men show improvements in muscle strength and physical performance similar to cisgender men. However, feminizing hormone therapy in nonathletic trans women leads to an increase in fat mass and a decrease in muscle mass, resulting in no advantage in physical performance compared to cisgender women after 2 years of GAHT.

Summary: This study conducted a systematic review and meta-analysis to investigate the effect of concurrent intake of carbohydrates (CHO) and caffeine (CAF) on exercise performance. The results showed that the concurrent ingestion of CHO and CAF can enhance sprint performance and reduce perceived exertion during steady-state exercise. However, the effect on time trial performance was inconclusive. The study also found that higher concentrations of CHO solution and a dose of 4-6.5 mg/kg of CAF were associated with the additive ergogenic effect.

Summary: Even though there is a clear agreement among researchers that psychological factors are a vital part of a football player's performance, the present study found that perceived mastery climate and extraversion were the only significant predictors of performance for female football players. Other indicators such as mental toughness, self-regulated learning, and grit did not predict performance. These findings suggest that the team climate facilitated by coaches may be more important for predicting match performance than individual psychological factors.

Summary: The present study evaluated tactical and physical performance during official matches of a women's soccer league and found correlations between both dimensions in 15-minute periods. Eight matches from the 2020-2021 season of the Women's Second Division in Spain were analyzed. Tactical variables (Width, Length, Height, and Surface Area) and physical variables (Total Distance Covered, Total Distance Covered in High-Speed Running, and Total Distance Covered in Sprint) were recorded. The study found no differences in the tactical dimension between periods, a decrease in total distance and high-speed running at the end of the match, and positive correlations among some variables in the tactical and physical dimension at different periods. Connecting the tactical and physical dimension would enhance the understanding of player and team performance during competition.

Summary: Emotional intelligence has a significant impact on students' performance in high school physical education exams. Self-confidence is positively correlated with emotional intelligence dimensions, while somatic anxiety is negatively correlated with performance. Hetero-emotional management has a positive effect on performance, while emotional perception has a negative effect.

Summary: Iron is essential for muscle function and oxygen transport in the body. Adequate iron levels are necessary for athletes, as deficiency can reduce physical performance. This review examines the importance of iron values, markers, and factors that can affect iron metabolism for physical performance.

Summary: Elite squash players train intensively indoors, which increases their hydration demands. This study aimed to measure the sweat rates, sweat sodium levels, and hydration practices of these players during a training session. The results showed that the players had a mean fluid balance of -1.22 +/- 1.22% and a mean sweat rate of 1.11 +/- 0.56 L.h(-1). There were significant differences between male and female players, and players training the following day were able to replenish fluid and sodium losses, while those training on the same day were not.

Summary: The study found that only aerobic capacity was significantly associated with more practice time, while tests on lower body power, anaerobic capacity, and upper body strength/endurance explained a small portion of the variance in ski performance.

Summary: This study characterized physical, functional, and cognitive performance in adults with hypophosphatasia (HPP), showing that HPP patients had deficits in walking distances, gait speed, upper extremity dexterity, fatigue, social functioning, pain, general health, as well as higher levels of depression, anxiety, and stress compared to the general population. This highlights the importance of objective assessments and specialized therapy for HPP patients.

Summary: The study investigated the relationships between boat acceleration and velocity in rowing, aiming to identify potential performance-enhancement strategies. Results showed that certain boat acceleration measures had significant effects before adjustment for stroke rate and power, but most effects reduced after adjustment, with some measures remaining significant in certain boat classes. These findings suggest that greater absolute values of certain acceleration measures are associated with improved performance in rowing, providing potential strategies for enhancing performance beyond increases in stroke rate and power output.

Summary: The review highlights the common use of GPS/GNSS technology in quantifying external acceleration load in team sport research, with count-based metrics being predominant. However, information regarding data processing and minimum effort duration is lacking in many studies, indicating a need for more detailed reporting in future research.

Summary: This study aimed to quantify the impact of matches and travel on the sleep, wellness, and training of Super Rugby players. The results showed that overseas matches led to reduced sleep and wellness levels, which recovered somewhat upon return. There were also differences between teams in the impact of matches on sleep and wellness.

Summary: This study established the validity of VisionKit computer vision system against three-dimensional motion capture in a stadium environment. The results showed strong agreement between VisionKit and three-dimensional motion capture across each activity. Therefore, VisionKit can be used to establish the concurrent validity of other electronic performance and tracking systems in circumstances where three-dimensional motion capture cannot be used.

Summary: This study aimed to determine if there were differences in acceleration during team-sport locomotion between different GNSS manufacturers. Data from professional rugby league athletes wearing devices from two manufacturers (GPSports EVO and STATSports Apex) were analyzed. The study found no substantial differences in speed and filtered acceleration between manufacturers, but there were substantial differences in acceleration variables derived from the proprietary software of each manufacturer.

Summary: This research adds context to a player's movement in football by analyzing the differences in movement metrics across phases of play and in-game win probabilities. The results demonstrate that there are differences in movement profiles across possession phases and in-game win probabilities, while overall positional trends are negligible.

Summary: The study examined the impact of the "six-again" rule change on athletes in the Australian National Rugby League. The analysis of GNSS data showed that the introduction of this rule led to a significant increase in acceleration for all positions and an overall higher average acceleration during matches. This suggests that the game of rugby league now requires athletes to have greater acceleration, and coaches should adjust their training programs accordingly.
