Todd Miller, PhD, CSCS, TSAC-F, FNSCA and professor at George Washington University discusses body composition measures and techniques and understanding body composition ranges and their effect on health and performance in this session from the NSCA's 2023 Personal Trainer's Conference.

Adequate nutrition generally promotes training adaptations and thus optimal performance. Adolescence is characterized by a pubescence growth spurt, increasing energy and nutrient needs. Most team sports literature focuses on male athletes, with little on adolescent female team sports. Adolescent female athletes are at an increased risk of inadequate energy, and micronutrient intakes because of the pursuit of high fitness levels, and society pressures. This may cause hormonal irregularities, delayed development, poor bone health, and increased risk of injury. This review synthesizes information on the nutritional needs of adolescent female team sport players for performance and health.

The purpose of this article is to introduce strength and conditioning specialists to autism spectrum disorder (ASD) and to identify the many benefits of delivering exercise programs to children with ASD. In addition, the article aims to inform strength and conditioning specialists on how to minimize some of the inherent challenges associated with the delivery of such programs by highlighting critical issues for practitioners to consider when designing and implementing exercise programs for children with ASD.

Agility is a key and complex concept within team sports performance. Because of its multidimensional nature, agility benefits from perceptual and cognitive skills as well as physical capacity (e.g., ability to exert acceleration, deceleration, and changes of direction). Agility should be integrated in different and complementary ways in team sports training. From more analytical to more ecological tasks, there is a need to comprehend the respective adaptations and identify how to integrate such a spectrum and, eventually, combine them in the training process and manage it accordingly to the player’s needs. Based on this premise, the purpose of this article is to present alternative methods and recommendations that may help to develop agility in field-based invasion sports. The main concepts pertaining to agility and associated capacities will be explored. Afterward, a proposal for a more analytical approach based on the use of cones and ladders will be introduced, as well as approaches based on small-sided games. Finally, an integration of agility training and a combination of approaches will be presented using soccer as an example.

The implementation of long-term athletic development (LTAD) aims to improve health, physical activity, and performance of all youth. Contemporary LTAD models suggest that a broad range of physical and psychosocial competencies should be developed in youth, but few resources are available for coaches that describe “how” to achieve these outcomes. This article overviews a coaching session framework built around the following components: raise, activate, mobilize, prepare, activity, games, evaluate (RAMPAGE). The framework provides practitioners with information on what can be planned and delivered and when within a coaching session, across multiple ages and stages of development within multiple contexts (e.g., physical education and talent development).

The countermovement jump (CMJ) is one of the most used performance assessments in strength and conditioning. Although numerous studies discuss the usability of different metrics in this test, this is often performed within the context of a specific aim. However, to our knowledge, no information currently exists providing practitioners with some over-arching recommendations on which metrics to choose when the purpose of using the test differs. This article discusses how the metrics selected to monitor during CMJ testing may differ when aiming to use it as a proxy for athletic performance, as part of neuromuscular fatigue monitoring, or as part of a test battery for return to performance in injured athletes.
