This article aims to explain why integrating multiple tests such as Anaerobic Speed Reserve (ASR), Intermittent Fitness Test (IFT), and Maximum Aerobic Speed (MAS) can provide a comprehensive evaluation of soccer players’ fitness levels and help to design effective training programs tailored to their individual needs.

The purpose of this article is to present a brief review of research on the safety and efficacy of caffeine used by athletes participating in anaerobic-dominant sports.

Duncan French explains the strength and conditioning work with MMA fighters in both their aerobic and anaerobic capacities at the UFC Performance Institute in this 2018 National Conference video.

Recent advances in research and human performance programs (HPP) has made it possible to learn more about the tactical athlete while creating enhanced methodologies and implementation. This review draws on the past three years of research focusing on strength and conditioning within military communities, exploring the current themes of research and the implications of future studies.

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.

Research shows that the appropriate integration of resistance training into the endurance athlete’s training can result in significantly better performance when compared to classic endurance training plans that focus only on aerobic endurance.

This excerpt briefly describes key aspects of this nonessential amino acid including its effect on the body, efficacy, and adverse effects.

This article provides a sample six-week, non-linear program for improving muscular strength, power, endurance, anaerobic capacity, and aerobic capacity. However, this is not a “one-size fits all” program, and manipulation of the program variables may be warranted for some individuals.

This Kinetic Select excerpt from the Essentials of Strength Training and Conditioning, Fourth Edition describes the results from electromyography (EMG) studies on the neural adaptations to anaerobic training.

This article discusses how high-intensity interval training may be an effective metabolic training method for soldiers trying to maintain physical preparedness during deployment.
