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 provides the first academic history of the barbell back squat and its evolution from a bodyweight exercise in the 19th century to a loaded exercise used for a variety of purposes in the present age. In doing so, the article highlights three key drivers in the evolution of the back squat—changes in equipment, the diversification of strength sports, and scientific communication concerning the safety and efficacy of the movement. The goal of this article was not to provide a dry and irrelevant history but rather to stress the complexity of the squat’s prominence within fitness programs and the need to hold a nuanced view toward the “optimal” way to approach this movement. It examines how the movement evolved from being primarily done on the tips of one’s toes, to a loaded movement on tippy toes, to a flat-footed movement. By contextualizing the back squat’s history, this article challenges rigid notions of “correct” squatting technique and encourages a more nuanced understanding of exercise selection in strength and conditioning practice. It concludes by highlighting the importance of critically examining the social construction of knowledge in fitness and sport, and the value of historical perspective in informing contemporary training practices

The Strength and Conditioning Journal is the professional journal for strength coaches, personal trainers, physical therapists, athletic trainers, and other health professionals working in the strength and conditioning field. The journal's mission is to publish articles that report both the practical applications of research findings and the knowledge gained by experienced professionals.

Exercise is increasingly recognized as an effective, nonpharmacological approach for managing both acute and chronic pain. However, accurate pain assessment methods tailored to different exercise settings and populations are essential. This review evaluates existing pain assessment techniques, highlighting self-report measures such as the Visual Analog Scale and Numerical Rating Scale, as well as quantitative measures, such as Pressure Pain Threshold and Conditioned Pain Modulation. These techniques provide valuable insights into the neurophysiological mechanisms behind pain reduction. Although exercise commonly produces a temporary reduction in pain sensitivity known as exercise-induced hypoalgesia (EIH), the effectiveness of this response depends on various factors, such as exercise intensity, psychological state, and pre-existing pain conditions. In addition, exercise itself can sometimes lead to short-term discomfort due to muscle fatigue or delayed-onset muscle soreness. This review offers strength and conditioning providers, as well as researchers, a clear framework for (a) selecting appropriate pain assessment tools, (b) designing research protocols, and (c) customizing exercise interventions for specific populations and pain conditions. By examining self-report and quantitative assessment techniques, along with considerations for data analysis and practical application, this review helps strength and conditioning professionals interpret the literature surrounding EIH and apply practical pain monitoring strategies to guide training and recovery in various populations.

Parkinson disease (PD) is a progressive and chronic neurodegenerative disorder that compromises both motor and nonmotor functions, ultimately leading to a decline in functional capacity and quality of life. Although the etiology of PD is multifaceted, exercise has shown promising effects in managing PD symptoms and enhancing patient well-being. Although aerobic and resistance exercise demonstrate benefits within this specific population, the exact application of these modalities varies and often differs depending on disease progression and the individual. Although individuals diagnosed with PD are encouraged to exercise, there is still a lack of information pertaining to how to successfully structure physical activity into their daily routine. There are also distinct barriers and motivators impacting their decision to engage in regular exercise. This manuscript offers practical recommendations and personalized exercise guidelines for exercise professionals, empowering them to optimize PD management through targeted exercise interventions. In addition, it offers current information on promoting exercise among patients with PD, specifically to enhance their functional outcomes.
