The primary aim of this study was to systematically compare the effectiveness of blood flow restriction training (BFR) versus traditional resistance training (TRT) to improve muscle size in healthy adults. Secondary outcomes were improvements in muscle strength and endurance. We performed a systematic searchwithmeta-analysis. Using predetermined criteria, 541 unique articles were identified through databases and bibliographies. After screening titles, abstracts, and full texts, 20 articles were included in the review. All 20 articles evaluated muscle hypertrophy, 19 evaluated strength, and 1 evaluated endurance in response to BFR and TRT. Data from 10 articles were included in the meta-analysis. In the qualitative analysis, TRT and BFR increased muscle size without differences between conditions for at least 1 hypertrophy outcome in 13 studies, and TRT or BFR differentially improved hypertrophy in 5 studies. TRT and BFR increased strength without differences between conditions for at least 1 outcome in 15 studies, and TRT or BFR differentially improved strength in 9 studies. Results from the meta-analysis indicate no differences in muscle size (ES 5 0.045, 95% CI [20.278 to 0.367]) or strength (ES520.149, 95% CI [20.439 to 0.141]) improvements with BFR versus TRT. Practitioners can implement BFR training to increase muscle size and strength as appropriate, especially for training periods of 8 weeks or longer.

Concurrent training (CT), which combines resistance exercise and energy systems conditioning, is the default approach to preparation in high-intensity intermittent (“stop and go”) team sports. This review provides an overview of CT, emphasizing its complexities and challenges in managing fatigue and optimizing performance. These complexities are specifically compounded by the variability in game demands across the season, where the presence of intensified and nonintensified competition periods necessitates a flexible and adaptive training approach. In this context, there are essential training variables to consider, including intensity, volume, session order, and recovery intervals between sessions. In addition, nontraining variables such as travel, sleep, and nutrition play a role in the fatigue experienced while training and competing. These variables interact to influence acute performance and training adaptations and can be strategically adjusted by strength and conditioning practitioners. The aim of this review is to provide a comprehensive understanding of fatigue management for practitioners in team sports, emphasizing the complexities and challenges of CT and offering simplified practical recommendations for adjusting training variables within any given microcycle.

Night after night, Cirque du Soleil’s performing arts athletes defy gravity and expectations — executing elite-level feats across 480 shows annually. Maintaining peak performance requires more than talent; it demands strategic preparation, adaptability, and trust. Channeling backgrounds in dance and martial arts, married coaching duo Mike and Jade Esmeralda bring a philosophy of continuous improvement to Cirque’s collectivistic infrastructure. Preparing performers with diverse training experiences, they connect on an artistic level to balance readiness with creative expression. From applying RAMP (Raise, Activate, Mobilize, Potentiate) warm-ups for mitigating injury risk to tactical load carriage insights for LED costumes, the Esmeraldas leverage parallels across high-performance environments. Strategies for Cirque’s “valuable human artistic assets” must enhance durability, manage load, and support longevity in an unpredictable, physically — and psychologically — demanding profession. Jade’s evidence-based journalism also combats social media misinformation. Discover how they adapt daily, build buy-in across cultures, and redefine training for a one-of-a-kind population.

The physiological response to breath holding includes bradycardia and peripheral vasoconstriction, which contrasts with that of exercise which includes tachycardia and peripheral vasodilation. This raises the question as to what the physiological response is to breath holding during exercise. During low-intensity exercise, the breath holding response of bradycardia and peripheral vasoconstriction prevails over the exercise response of tachycardia and peripheral vasodilation, but nevertheless the exercise may be sustained. Due to the lack of availability of extrinsic oxygen (O 2 ) from the atmosphere during breath holding, the energy demands can be met by increased reliance on intrinsic O 2 stores (i.e., O 2 that was in the body before the breath hold) via increased O 2 extraction at the muscle compared with exercise while breathing, or increased contributions from anaerobic energy systems. During high intensity exercise of short duration, the exercise response may prevail over the breath holding response due to the increased parasympathetic withdrawal and sympathetic drive of higher intensity exercise. If breath holding during high-intensity exercise was sustained for long enough, the breath holding response may eventually overcome the exercise response, although this may be difficult due to the inverse relationship between exercise intensity and breath hold duration.

Bob Alejo, Director of Sports Science at Power Lift, talks to the NSCA Head Strength and Conditioning Coach, Scott Caulfield, about how Bob got into Strength and conditioning when the field was in its early stages of development. Bob shares his experience and gives advice on how to succeed in the strength and conditioning field.

This article looks to explain why law enforcement recruits have higher incidences of lower extremity bone stress responses and stress fractures. It also explores injury mitigation pathways to increase the graduation rates among law enforcement academies.

Antonio Squillante, a PhD candidate at the University of Southern California (USC) and the Weightlifting Special Interest Group (SIG) chair, talks to the former NSCA Head Strength and Conditioning Coach, Scott Caulfield, about using weightlifting, not just the sport, as a means to build strength and power in athletes from the platform to the field. Topics under discussion include being involved with the NSCA through leading the Weightlifting SIG and teaching Exam Prep classes, moving from Italy to pursue his dream of coaching, and going back to school for his PhD.
