The purpose of this article is to review the related literature that has explored the influence of resistance training programs on the onset of fatigue and muscular power as it relates to non-contact high-intensity intermittent sports, in order to provide suggestions for creating same-day training programs.

This article discusses using the principle of specificity as an important component in tactical training programs to enhance performance, decrease injuries, and improve functional longevity of a tactical athlete.

This excerpt from NSCA’s Essentials of Sport Science highlights the importance of quantifying training load for both programming and monitoring an athlete’s progression or regression over time.

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.

This article introduces a periodization model designed for beginner to elite perinatal athletes, emphasizing trimester-phased training aligning with gestation, delivery, and postpartum needs. Amid progressing global recommendations on perinatal exercise and increasing female participation in high-intensity and strength training, the primary aim is to propose an evidence-based, structured approach to training that consolidates these trends. The physical and psychological demands of labor mirrors that of an athletic endeavor. As such, this article explores emerging evidence supporting maternal and fetal safety and benefit of high-intensity training, allowing pregnant individuals to prepare in accordance with the task ahead. Training phases parallel to preseason, in-season, peaking, and recovery shift in focus based on the physiological need and biomechanical necessity within the pregnancy timeline. This translation of science to practice underscores the potential for tailored training programs to positively impact maternal, fetal, and neonatal health, urging further research and unified guidelines in this evolving field.

The loading intensity a person chooses depends on his or her goals and training status (i.e., whether the person is a trained athlete or a sedentary individual). Ultimately, the number of repetitions you can perform at a given intensity or load determines the effects of training on strength develop.

This excerpt briefly discusses components of interval workouts, including recommended volume and intensity, to increase overall endurance in athletes.

Much in the same way that a single movement or a single workout does not make or break a training cycle, the same holds true for mental skills. The challenge is that the strength and conditioning coach will likely need to reach out to another professional trained in sport psychology to help establish the plan and construct the appropriate interventions.

Live high/train low: what changes can be expected, what dose is required, and is it preferable to other training models for improving performance in endurance sports such as running, swimming, and cycling?

This book excerpt discusses how to maximize sprint quality during training sessions.
