Summary: The aims of this scoping review were to characterize the main methodological approaches to assessing individualized running speed thresholds in team sports players, compare the use of traditional arbitrary thresholds with individualized thresholds, provide an evidence gap map about the approaches and study designs used in team sports investigations, and give directions for future research and practical applications in the strength and conditioning field. The review identified 36 eligible articles out of 3,195 potentially relevant articles, with 27 focusing on the use of arbitrary and individualized running speed thresholds and 34 using individualized thresholds based on physical fitness assessments or performance. The review emphasized the need to improve the methodological aspects of using individualized speed running thresholds and consider the population and context of each study in research comparing different measures and approaches to individualization.

Summary: The study compared the validity and reliability of local and global position measurement systems for measuring acceleration during team sports. Both systems tended to underestimate maximal acceleration, especially during changes of direction. Global Positioning System (GPS) showed better reliability in measuring maximal running speed compared to Local Positioning Measurement (LPM).

Summary: The study aimed to examine the relationship between team numerical advantage and match event outcomes in professional Australian football, and also analyzed how players occupy different field areas during match play. Results showed that an increased team numerical advantage led to a greater likelihood of gaining possession or generating a score, but more total players inside 50 were associated with a decrease in scoring probability. Teams were often outnumbered in their forward 50 but had a numerical advantage in the defensive 50.

Summary: High-speed running and sprinting training are crucial for soccer players' physical development, performance enhancement, and injury prevention. The recommended methods include high-intensity running training, field-based drills, and ball-drills in the form of medium- and large-sided games to optimize training responses and long-term effects.

Summary: This study evaluates the influence of the inter-vehicle suspension (IVS) on the running of high-speed trains under crosswind conditions. By establishing a multibody model and conducting numerical simulations, it is found that the radius of the curved track significantly affects the safety characteristics of the train, and the IVS leads to lower safe speeds but provides more realistic and credible dynamics.

Summary: Starters have higher values at the beginning of the season and lower values in the middle to end of the season, while non-starters have higher values in the early season and lower values in the late season. This study provides insights for coaches to better plan training periodization during the soccer season.

Summary: The study revealed significant variations in match duration, accelerometer variables, and MPA within and between matches. Regardless of match outcome, the first half appears to produce greater outputs.

Summary: Research indicates a significant relationship between change of direction speed (CODS) and sprint speed, muscle strength, and jump ability, with the strength of this relationship depending on test design and parameters analyzed. Future studies should focus on test design and parameter selection to align with the fitness demands of specific sports.

Summary: This study compared the impact of drafting on physical intensity (heart rate) and perceived intensity (ratings of perceived exertion) in team pursuit races in long-track speed skating. The results showed that the heart rate was lower in the second and third positions compared to the first position, and the heart rate was lower in the third position compared to the second position. The perceived intensity was lower in the second and third positions compared to the first position, and there was no significant difference in perceived intensity between the second and third positions.

Summary: This study investigated the effects of longitudinal and lateral spacing on the aerodynamic drag characteristics of the whole team and each member in speed skating team pursuit competition. The results showed that decreasing the longitudinal spacing resulted in greater drag reduction for the whole team and individual skaters. Furthermore, lateral movement of the leading skater also led to additional drag reduction for the team. Computational fluid dynamics simulations revealed differences in drag distribution between the leading skater and the middle and last skaters.

Summary: This study examined the rehydration process after intermittent running and found that a small degree of hypohydration remained even when subjects drank fluids ad-libitum during and after exercise. The results suggest that athletes may still experience dehydration to some extent despite fluid intake in free-living conditions.

Summary: In a Portuguese professional football team, midfielders and wide midfielders covered significantly greater total distance and average speed during matches, while wide midfielders and fullbacks showed better performance in high-speed running and sprinting. Match running performance of players in different positions was influenced by match location, quality of opposition, and match outcome.

Summary: This study establishes a link between the measured steady-state switching rates of the flagellar rotary system and the directional changes of individual swimming bacteria in a gradient, using a probabilistic model. The complex response of a bacterial population to the gradient suggests that both the average speed and distribution width of the response should be considered when optimizing the overall population's performance in complex environments.

Summary: This study aimed to quantify the between-match variability in peak match running intensities and found greater variability in average acceleration and relative high-speed running. These findings help to understand match performance and inform training plans.

Summary: The study found that a 2-week elite team-sport training camp significantly improved maximal oxygen uptake, repeated-sprint ability, and aerobic performance in rugby players. However, adding heat and/or altitude training did not further enhance performance, and altitude training appeared to be detrimental to improving Yo-Yo performance.

Summary: The growth of sport science technology enables sporting teams to monitor performance and workload of athletes. However, there is a lack of longitudinal athlete monitoring literature for youth athletes, especially in indoor sports like basketball. This study evaluated the effectiveness of different athlete monitoring methods over 10 weeks of youth basketball training. The findings showed that monitoring methods using IMU data combined with PlayerLoad data analysis were more effective in monitoring accumulated load compared to HR analysis. Despite small correlations, all six methods of athlete monitoring detected similar trends for all sessions.

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: Changes in the volume and intensity of AFL match demands occurred in discrete periods from 2007 to 2010 and 2010 to 2012, influenced by rule and interpretation changes as well as coaching strategies. Standardisation of GPS data reporting is recommended to address inconsistencies in the literature.
