The purpose of this article is to discuss the different opinions regarding the validity of early sport specialization as opposed to diversification, specifically the effect these two methods have on injuries, motor development, skill acquisition, and social and psychological aspects.

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.

This article is the second part of a two-part series that considers the potential role strength and conditioning coaches have in developing student-athlete leadership.

Puberty is a critical period for young athletes, characterized by significant physical, psychological, and social changes. During puberty, young athletes experience the adolescent growth spurt at the same time as intensified training regimens, which can affect performance, injury risk, and overall health. Systematic training can improve physiological and performance outcomes, but the increased training volume and changes to the body during adolescence can also heighten the risk of injuries. This article discusses the injury risks associated with adolescent growth and provides comprehensive recommendations to mitigate these risks. Key recommendations include limiting training hours to the athlete’s age, monitoring growth and maturation to adjust training loads and content, and incorporating and modifying consistent strength and conditioning prescriptions. In addition, optimal nutrition, sleep, and interdisciplinary planning among coaches, parents, and stakeholders should be emphasized to support young athletes’ holistic development and well-being during the adolescent growth spurt.

As rotation, power, and rotational power are all common pieces of everyday life, it is important to train for efficiency in the movements. This article addresses the specific approaches rotational training can have in an individual’s strength program to address core integrity, synergistic muscular systems, and overall athletic capabilities as it relates to aging.
