Long-Term Athletic Development (LTAD) models have provided a youth sport framework for more than 2 decades, aimed at improving skill progression, training outcomes, and athlete preparation. Although influential, traditional LTAD approaches are limited by their sport-centric orientation, linear design, and focus on elite performance, leaving them less relevant for most youth and adults who do not pursue competitive sport. In response, we propose reframing LTAD as Long-Term Activity Development (LTActD), an accessible and flexible model designed to promote lifelong engagement in physical activity, including recreation, exercise, and sport. LTActD emphasizes 5 dynamic phases—Explore, Develop, Apply, Sustain, and Thrive—that accommodate diverse pathways, periods of inactivity, and opportunities to re-enter active living at any age. Represented as a curvy road, the new model underscores that participation in physical activity is rarely linear, more like a winding journey shaped by health, motivation, environment, and social context. LTActD bridges sport science and public health, positioning physical activity as a lifelong resource for health, independence, and fulfillment. LTActD offers a practical framework to empower individuals of all ages and abilities to discover meaningful ways to move, re-engage, and embrace active living throughout the life course.

RED-S and low energy availability often stay silent — until something happens. Your athletes and clients may be unintentionally underfueling at any training level or body size. Carolyn Stocker, MS, RD, LD, CSCS, brings practical myth-busting to common fears around fueling. Spot signs sooner, understand what’s driving them, and help athletes fuel with confidence.

Various methods of eccentric training that aim to increase muscle mass or reduce ground contact time during a landing task have been extensively researched and practically examined. However, multiple methods to implement eccentric training currently exist; they differ in execution and intended training adaptions. There is a clear differentiation between an eccentric muscle action and an eccentric motion whereby a motion alludes to a downward movement of an exercise. The proposed eccentric motions are dissipating eccentrics, deceleration eccentrics, overcoming eccentrics, maximal eccentrics, and rebound eccentrics. These motions formulate into training methods and cues to allow practitioners to clearly differentiate the various eccentric training methods used in research and practice. This review proposes a new conceptual framework that clearly outlines the different forms of eccentric motions that fall into a desired eccentric training method.

From the 2019 Tactical Annual Training, Rob Orr, co-lead of Bond University’s Tactical Research Unit, explains how the backs of tactical personnel can be compromised. He also details the systems that affect the back and how to construct programs to optimize physical conditioning and reconditioning.

Velocity-based training (VBT) is an increasingly popular programming strategy used by strength and conditioning professionals to develop their athlete’s ability to express force rapidly. To implement the varying forms of VBT effectively within their training regimes, strength and conditioning professionals need to understand the strengths and weaknesses of strategies, such as predicting 1 repetition maximum using the load-velocity profile, modulating training loads using the load-velocity profile, and controlling training volume using the magnitude of velocity-loss. The aim of this review was to highlight these strengths and weaknesses and then provide practical examples of when each programming strategy may be most effectively implemented.

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.
