High chronic workloads have been shown to be associated with a reduced risk of non-contact, soft tissue injuries, while large spikes in acute training loads have been associated with an increased risk of these types of injury. Analyzing the acute:chronic workload ratio allows a coach to optimize training for the athlete and to continue in advancing fitness goals without overtraining.

This article addresses various aspects of overtraining and overreaching, including the signs and symptoms, preventative supplementation, and the recovery process.

Because a client’s functional abilities will change in each of the tissue healing phases, the fitness professional must understand the time it takes to heal and the science behind each phase in order to prescribe safe exercises for clients in those phases.

For many athletes, being agile is the end goal of physical performance training. It represents their capacity to change velocity and direction in response to the actions of their opponent and the opportunities and constraints of their environment. The aim of this article was to describe the pitch-based development of agility, focusing on 60–1808 turns. This ensures all turns have the demand of deceleration, turning, and reacceleration, requiring both outside leg turns (608) and inside leg turns (1808). To enable the effective coaching of these, coaches must understand movement mechanics and thus the fundamental principles that underpin good technique. Within agility training, a detailed appreciation of how the center of mass and base of support interact to affect the direction of force is fundamental to this. This understanding and the ensuing technical models ensure athletes have the best chance of executing the task optimally and ensure coaches can effectively instruct athletes and adapt drills accordingly.

This 2018 Personal Trainers Conference video features Lee Boyce going over the subject of anthropometry and the mechanics of the fundamental movements in strength training. Boyce describes the common issues you see and how to individualize movements for your clients.
