Summary: This study examined the physical match performance of 25 professional soccer players in different positions using data from the 2019/20 German Bundesliga season. It was found that players adapted or maintained their performance differently when playing in various positions, with large individual differences. Coaches and practitioners should take into consideration these differences in training and recovery processes.

Summary: This study aimed to investigate the impact of effective playing time on physical match performance in professional soccer, categorizing players by their playing positions. The findings revealed that effective playing time had an influence on total distance and accelerations, and there were slight variations in the physical performance of wide midfielders and forwards compared to other positions.

Summary: This case study examined the use of spatiotemporal data to develop key metrics for evaluating and understanding the performance of elite soccer referees during a match. The study focused on different performance metrics, such as alignment of assistant referees, positional density of the referee, and distance from the referee to the ball. These findings can be used to create normative behavior models based on the referees' movement performance in soccer.

Summary: This study evaluated the relationship between laboratory-measured (V)over doto(2)max and match running performance but found no correlation. Players covered greater distances in the first half and performance varied based on playing positions, with midfielders covering more distance in high-intensity running and fast running zones.

Summary: The study aimed to investigate the relationship between aerobic capacity and running performance in soccer players with visual impairment, as well as to describe the physiological parameters and running distances during matches. The findings showed that relative VO2max was not related to running performance, indicating that tactics, playing style, and player position may have a greater impact on the distances covered.

Summary: This study assessed the external load in amateur soccer matches and analyzed the differences between playing positions, match locations, and championship phases. The results showed significant differences between playing positions for all external load measures, while match locations and championship phases did not appear to have a major influence on the external load.

Summary: The study found that winning increased the total distance covered by midfielders, wide midfielders, and forwards, while losing increased the total distance covered by central defenders and wide defenders. Additionally, the distance covered with and without ball possession varied depending on the match outcome, indicating that the evolution of scoreline significantly influences tactical-technical and physical demands in soccer matches.

Summary: This review systematically examines the match-play characteristics of women's soccer, including physical, technical, and tactical aspects. The findings suggest that match-performance increases with age-groups and playing standards, and varies between playing positions. However, more research is needed to understand the potential differences in technical and tactical performance.

Summary: The aim of this study was to analyze the relationships among physical cognitive ability, academic performance, and physical fitness regarding age and sex. The study included 187 students (53.48% male, 46.52% female) aged between 9 and 15 years old (M = 11.97, SD = 1.99) from a town in Jaen, Andalusia, Spain. The results showed a significant relationship between physical fitness, attention, and concentration. There were differences in cognitive functioning scores between sexes and age categories, with girls and older students performing better.

Summary: In this study, a cellular SLAM framework based on 5G signals and inertial measurements is proposed for mobile robot localization. The method outputs the robot's pose based on RSSI measurements and generates a radio signal map for correction. The results show that 5G positioning can provide increased robustness in outdoor environments and assist in robot localization when LiDAR methods fail and GNSS data is unreliable.

Summary: This study aimed to examine the acute effects of moderate-intensity aerobic and high-intensity interval exercise protocols on Asprosin and Brain-Derived Neurotrophic Factor (BDNF) levels in inactive normal weight and obese individuals. The results showed that serum asprosin was higher and BDNF was lower in the obese group compared to the normal weight group. Both moderate aerobic exercise and high-intensity interval exercise significantly decreased asprosin levels in both groups. The obese group showed a significant increase in BDNF levels after high-intensity interval exercise. Acute exercises of different intensities have important effects on appetite regulation hormones, particularly in the obese group.

Summary: This study investigated the effects of three typical football training sessions on neuromuscular responses and examined the reliability of peak speed (PS) measured during a submaximal running test (SRT) in identifying neuromuscular fatigue (NMF) status. The results showed a significant decrease in all variables after the training sessions. The external load variables of each football session differed significantly. The study also demonstrated that PS can be a reliable measure for monitoring NMF status.

Summary: This study compared the external match load of a Turkish Super League team considering different playing positions and in-season periods by observing 29 official matches. The findings showed that defenders consistently displayed the lowest values in all external load measures during matches compared to other positions. Midfielders demonstrated a higher activity profile during the initial and middle stages of the season with a slight tendency to decrease load towards the end of the season.

Summary: This systematic review with meta-analysis aimed to compare the endurance performance adaptations induced by running-based high-intensity interval training (HIIT), small-sided games (SSGs), and combined HIIT+SSGs in male and female youth and adult soccer players. The findings suggest similar effects induced by both SSG and HIIT on improving endurance performance and VO2max.

Summary: This study used machine learning to predict professional soccer players' positions based on specific locomotor demands. Data from 20 male professional soccer players from the same team were tracked using a global navigation satellite system. Four predictive models were created using different algorithms and evaluated using performance measures. The results showed that the random forest model achieved perfect accuracy, and running distance, total distance, and player load were identified as the most important factors in predicting player positions. This machine learning approach can help reduce false alarms and player mispositioning.

Summary: The aim of this systematic review is to summarize the main evidence about the variations of ACWR and training monotony over the season in professional soccer players. The study found that there are differences in the range values of ACWR and training monotony, and their real value should be considered before using them to reduce injury risk.

Summary: This study aimed to analyze the differences in training:match load ratios between positions and examine the relationship between weekly training and match demands in male professional football players. A cohort study lasting 43 weeks was conducted with 19 players using GPS units. The study found significant position differences in decelerations and moderate correlations between weekly training and match demands and mean training intensity and match demands. However, these correlations are too weak to suggest a cause-and-effect relationship.

Summary: This systematic review with meta-analysis aimed to analyze the effects of plyometric-jump training (PJT) on physical fitness and sport-specific performance in youth. The results showed that PJT resulted in improvements in measures such as maximal dynamic strength, linear sprint speed, horizontal jump performance, reactive strength index, and sport-specific performance. These benefits seemed to occur regardless of the participants' maturity status.
