This excerpt from Developing Agility and Quickness provides a needs analysis for field hockey and possible program design options for optimal performance outcomes.

Acceleration is the rate of change in velocity, so this phase of sprinting is critical for changing directions as rapidly and efficiently as possible. Optimal technique for linear sprinting in the acceleration phase involves four factors that maximize stride length and frequency.

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.

In the second of this two part series, this article will discuss program design with an emphasis on integrating lower limb plyometric training into soccer training to enhance power actions, as well as, consider high school athletes’ biological characteristics and long-term athletic development (LTAD).

The goal of this brief review is to describe what classifies as high-intensity interval training (HIIT) and summarize the potential benefits for various populations: athletic, general, and clinical.
