Summary: Resistance training (RT) is effective in improving and maintaining skeletal muscle mass, strength, and power, with various health benefits. However, low participation rates may be attributed to factors such as time constraints and perceived difficulty, and strategies to reduce barriers to participation are needed.

Summary: Research on ACL reconstruction and postoperative rehabilitation has been reexamined to optimize clinical outcomes and return to sport. By systematically revisiting practice guidelines and validating clinical milestones, combining the latest research and direct clinical data provides a current and realistic strategy for rehabilitation. Key updates include the use of frequent quadriceps strength testing and criterion-based progressions for return to sport activities.

Summary: Autoregulation training is a resistance training approach that adjusts training prescription based on individual rates of adaptation. This study compared the effectiveness of subjective (rating of perceived exertion) and objective (barbell velocity) intensity descriptors in improving sport-specific physical performance measures. The results showed that autoregulation programming with objective intensity prescription led to larger improvements in strength and countermovement jump performance, but had little effect on sprint performance.

Summary: This review critically reflects on power profiling strategies in cycling, provides updated viewpoints for applied researchers, and suggests that field testing should always adhere to pre-established guidelines. Power-duration parameters can be derived from the critical power model.

Summary: There is a lack of high-quality evidence to support rehabilitation and return-to-sport decisions for athletes with shoulder injuries. The Athlete Shoulder Consensus Group used a 2-round Delphi process and an in-person meeting to develop a consensus statement that provides guidance on load and risk management, athlete shoulder rehabilitation, and decision making during the return-to-sport process. The principles and consensus of experts across various sports may serve as a template for developing sport-specific guidance in the future.

Summary: This study aimed to investigate the effects of verbal velocity performance feedback during the free-weight bench press exercise on the within-session reliability and magnitude of mean concentric velocity (MCV) as well as the accuracy of estimating the bench press one repetition maximum (1RM). The results showed that providing velocity performance feedback increased the reliability and magnitude of MCV for the 40% 1RM load, but had no significant effects on higher loads. Additionally, the accuracy of 1RM estimation was higher when velocity performance feedback was provided.

Summary: The study aimed to investigate the association between asymmetry and speed and change of direction speed (CODS) performance, as well as the potential changes in performance associated with changes in asymmetry. The results showed significant correlations between DJ height asymmetry and 10-m sprint time, as well as 505 time on the right limb at the end of the season. However, no significant correlations between changes in asymmetry and changes in speed or CODS were found at any time point. Therefore, it cannot be concluded that reducing asymmetry indirectly enhances athletic performance.

Summary: This study identified predictors of ACL graft failure in high-risk patients and indicated that adding a lateral extra-articular tenodesis (LET) and using a larger graft diameter can significantly reduce the odds of asymmetric pivot shift. Conversely, factors such as younger age, greater posterior tibial slope, high-grade knee laxity, and earlier return to sport were associated with increased odds of graft rupture.

Summary: This systematic review and meta-analysis found that resistance training can significantly reduce body fat percentage, body fat mass, and visceral fat in healthy adults. Measurement type was a significant moderator in body fat percentage and body fat mass, but sex was not.

Summary: This article highlights the importance of non-invasive identification of lactate threshold and respiratory compensation point during incremental exercise through pulmonary gas exchange and ventilatory variables. It also provides practical strategies for explaining the physiological mechanisms, identifying thresholds, and addressing related issues, as well as an online tool for practice and data analysis.

Summary: This systematic review examines how wearable technology is being used for running gait analysis in adults. The majority of studies focus on young adult recreational runners and use inertial measurement units to monitor running mechanics. The outcomes measured include ground contact time, stride length, stride frequency, and tibial acceleration. Future studies should aim to establish consensus on terminology, validity testing protocols, reliability of devices, and suitability of gait outcomes.

Summary: The COVID-19 pandemic has negatively affected the mental and emotional health of athletes globally, with an increased risk of poor mental health outcomes for female athletes and those in higher levels of play. Providing psychological support, access to training facilities, and utilizing healthy coping mechanisms can improve mental health outcomes for athletes.

Summary: Robot-assisted knee arthroplasty allows for more accurate component positioning but significantly prolongs operation time. While robotic assistance improves component alignment, its benefits in terms of clinical scores, patient satisfaction, and implant survivorship need further validation.

Summary: The study aimed to analyze the gap widths and differences in varus knees in different flexion angles, finding a high variability among individuals. While varus deformity correlated with medio-lateral gap difference in extension, no correlation was found in flexion. Women tended to have larger gap sizes, while age and BMI had no significant effect. Individualized balancing techniques are necessary for treating varus knees effectively.

Summary: This study aimed to investigate the differences in volleyball-specific skills, physical performance, and cognitive functions between players of different competitive levels. The findings showed that regional players had higher accuracy and technique in serving, passing, spiking, and setting, as well as better change of direction speed and countermovement jump performance compared to provincial players. Regional players also exhibited faster response times in cognitive tasks. Machine learning models were able to accurately predict players' competitive levels using a combination of passing technique, cognitive task performance, and spiking technique.

Summary: This study examined the effects of blood flow restriction (BFR) training on power output and bar velocity during the bench press exercise. The results showed that short-term BFR training significantly increased power output and bar velocity. The width of the cuff was found to be a critical factor in determining the acute exercise adaptation during BFR resistance training.
