Summary: The objectives of this study were to examine the effects of elite rugby league competition on mental fatigue and to investigate the influence of mental fatigue on in-match technical performance. The findings showed that elite rugby league players experienced increased mental fatigue after games, with backs reporting greater increases than forwards. Furthermore, higher levels of mental fatigue were associated with a lower percentage of positive involvements during matches.

Summary: This study aimed to investigate the effects of a simulated rugby league match on decision-making in elite junior players. The results show that despite a decline in neuromuscular function during the simulation, decision-making performance was not significantly affected, indicating that elite junior rugby league players are capable of sustaining performance during a progressively fatiguing match simulation.

Summary: This study aimed to establish reference values for countermovement jump (CMJ) performance in top-level senior rugby league players, specifically for jump height (JH), reactive strength index modified (RSImod), and mean (PPmean) and peak (PPpeak) propulsion power relative to body mass. The study found that backs outperformed forwards in all CMJ metrics, supporting the need for position-specific reference values.

Summary: This study aimed to explore the perceptions of elite NRL players and staff on the annual training and competition calendar from a player workload and well-being perspective. The findings showed that NRL players and staff believe players are comfortable with the current number of games but are already at their maximum capacity. The study also identified minority groups that may need support to enhance player well-being.

Summary: This study compared the match durations, locomotor characteristics, and event characteristics of Super League (SL) seasons in 2018, 2019, and 2020. Rule changes had a significant impact on whole-match durations and locomotor characteristics, while their effects during ball-in-play periods were less pronounced.

Summary: This study identified key physical and technical-tactical performance indicators that can classify between levels of rugby league match-play. For backs, a combination of PlayerLoad(2D), PlayerLoad(SLOW) per Kg body mass, and high-speed running distance were most important, while defensive play-the-ball losses stood out for forwards in classification. These identified indicators and combinations can be developed in training to aid players in progressing through the rugby league playing pathway.

Summary: The purpose of this study was to compare the effects of variable-resistance complex training (VRCT) versus traditional complex training (TCT) on strength, power, speed, and leg stiffness (K-leg) in rugby league players. The results showed that both VRCT and TCT significantly improved 1RM back squat, countermovement jump peak power, and 5-m sprint time. VRCT and TCT can be implemented during the competitive season to improve strength, power, and 5-m sprint time, with VRCT potentially leading to greater improvements in reactive strength index and K-leg, and TCT enhancing 10- and 20-m sprint times.

Summary: This study found that senior and junior rugby league players exhibit different patterns of improvements in lower-body strength and power during different phases of the season. Senior players showed increases in strength and power at the end of the preseason, but no changes during the in-season. Junior players did not show changes in strength, but had significant increases in absolute and relative strength and power during the in-season. These findings emphasize the importance of differentiating training programs for junior and senior athletes and targeting different physical qualities at different times of the season.

Summary: This study aimed to quantify the incidence of concussion in male rugby league and compare it between different playing levels. The results showed that the incidence of concussion was higher in the Super League and Academy compared to the Championship, and the incidence in the Academy increased over time. Various factors, such as changes in medical standards and knowledge, may have influenced the identification and diagnosis of concussion.

Summary: Water use, inefficient irrigation methods, and climate change have led to depletion and insecurity of water resources, impacting the agricultural system's stability. Sustainable management performance requires defining benchmarks and comparing them, with indicators of water, energy, and food sustainability playing a crucial role. Through the use of Analytical Hierarchy Process (AHP), this study selected and ranked sustainability performance indicators (SPIs) for agricultural systems, with indicators such as water consumption and groundwater stability being identified as key for system sustainability on a basin scale.

Summary: The role of strength and conditioning coaches has evolved with the influx of data, requiring them to possess skills in data analysis and understand the validity of statistical terms. This review is divided into two parts, discussing the importance of null hypothesis significance testing, p values, error rates in the first part, and introducing effect sizes, measures of variability, and confidence intervals in the second part for reporting group-based changes in performance-based sports.

Summary: This study is the first to report the overall demands of professional soccer players in the English Championship, showing that whole match demands are lower than ball-in-play demands and there are differences in match demands at different time intervals. Player positions do not have a significant impact on match demands.

Summary: This study explored the use of debriefing in boxing through interviews with experienced coaches and professional boxers. The findings emphasized the importance of using data, video, and integrating performance analysis to provide comprehensive feedback and maximize learning opportunities. It was also highlighted that establishing an open and honest relationship and creating a safe space for athletes to actively engage in the debriefing process are crucial. The length of the debriefing session did not seem to affect overall engagement.

Summary: This study investigated the agreement between coaches and performance analysts in the delivery of performance analysis in Olympic and Paralympic environments. The results demonstrated clear consensus on the importance and provision of full video. However, coaches placed greater emphasis on coaching philosophy, training goals, and discussions with athletes, while analysts were less aware of these factors. Time emerged as a potential barrier for effective communication.
