A significant number of resistance training injuries occur at the shoulder complex. However, there is a lack of research identifying predictive variables, which may increase the risk of these injuries. Certain exercises, such as those requiring the apprehension position (glenohumeral abduction with external rotation), have been investigated and found to be associated with shoulder pain and injury. However, there are additional exercises or positions that may also be associated with increased injury risk. The position of end-range glenohumeral extension, particularly as it pertains to a dip, is a vulnerable position that may have previously been overlooked.

The importance of physical fitness is never greater than when lives are at stake. Specifically, professionals in law enforcement, fire/rescue, and the military need fitness and tactical athleticism to efficiently respond to calls and complete missions regardless of the obstacles, mixed terrain, interference, and dangerous environmental conditions involved

Blood pressure changes acutely during resistance exercise. Continuous, beat-by-beat assessment provides detailed temporal resolution of blood pressure profiles, through techniques including intra-arterial catheterization, photoplethysmography, or applanation tonometry. However, noncontinuous measurements may be conducted before and after resistance exercise through auscultatory sphygmomanometry or oscillometry. Blood pressures tend to increase across repetitions within sets, influenced by load magnitude, repetitions and sets performed, muscle mass recruited, and rest periods; the highest pressures result from multi-joint, large muscle group exercises. Evaluation of such factors may facilitate better understanding of blood pressure responses to acute resistance exercise and influence program design considerations relative to anticipated hemodynamic changes.

Hybrid fitness competitions such as HYROX have rapidly gained popularity, blending aerobic endurance running with a variety of high-intensity resistance and ergometer-based stations in a globally standardized format. The sport’s unique structure, comprising eight 1-kilometer runs interspersed with diverse workload stations, presents distinct physiologic, biomechanical, and technical demands. This review synthesizes existing research on hybrid fitness events to identify the key determinants of HYROX performance, emphasizing aerobic capacity, anaerobic power, local muscular endurance, and maximal strength. The aerobic system is foundational, enabling recovery between high-intensity efforts and sustaining performance during the event’s prolonged duration. Conversely, anaerobic capacity is critical for executing the high-intensity efforts demanded by each fitness station. Local muscular endurance supports repeated submaximal contractions, while strength and power underpin performance in movements such as sled pushes and running economy. Technical proficiency and injury prevention strategies are also discussed, alongside targeted programming recommendations, including high-intensity interval training, circuit training, and blood flow restriction methods. Despite its growing popularity, limited sport-specific research exists, necessitating further investigation to refine training and performance strategies. This review provides a comprehensive framework for athletes and coaches to optimize preparation and performance in HYROX, contributing to the broader understanding of hybrid fitness competitions.

Since traditional sport-specific training or exercise programs do not create enough stimulus to improve the function of the respiratory muscles, the rationale to introduce respiratory muscle training (RMT) emerged. RMT is associated with improved endurance performance and pulmonary function, and it reduced respiratory fatigue, perceived exertion, or breathlessness. The purpose of this article is to provide coaches with tools to select the appropriate form of RMT in the context of the athletes’ needs, using appropriate methods, techniques, devices, and testing protocols.
