As the final article of the three-part series on long-term athletic development (LTAD), this article will focus on enhancing physical fitness and participation in LTAD programs that promote physical fitness and physiological wellbeing, regardless of age, ability, and aspirations.

This article discusses overtraining risk factors in endurance athletes and provides strategies for optimizing effective programming. Visit NSCA online to learn more about athletic performance.

Various aspects of resistance training, such as specific exercises chosen, workout structure, resistance used, volume (repetitions and sets), rest intervals between sets, and training frequency, can be manipulated to mold the strength training program to best meet an endurance athlete’s goals.

Learn about the emerging field of biomechanics in professional baseball from Georgia Giblin, the Director of Performance Science for the Detroit Tigers Major League Baseball (MLB) team. Giblin shares her professional journey with NSCA Coaching and Sport Science Program Manager, Eric McMahon, from working with Olympic athletes in Australia to educating coaches on emerging technology tools within MLB. This episode features discussion on the recent growth of athletic performance departments, the current state of sport science in the United States, and the helpful role of strength and conditioning coaches in supporting sport science initiatives.

Interest is growing in warm-up procedures that involve dynamic activities and sport-specific movements that maximize active ranges of motion at different movement-specific speeds while preparing the body for the demands of sport training and competition.

How can lessons from professional football help you prepare injured athletes to return to competition? Thomas Myslinski III is the Reconditioning and Return to Football Coach for the New York Jets in the National Football League (NFL). A third-generation strength and conditioning coach, Myslinski recalls the joy of tagging along at NFL training camps with his father, who encouraged him to learn beyond one specialty. He discusses workload management and how sport science helps him understand each player’s progress. Myslinski reverse engineers each player’s programming from sport demands and adjusts it to their current capacity. He describes himself and his sports medicine counterpart as “partners in everything” and explains how he keeps fellow strength and conditioning coaches informed. Looking ahead, he considers how strength coaches can match technology to training goals and plan recovery as deliberately as training. Hear what you need to know about a returning player, and what information your colleagues need you to share.

Tom Williams’ journey to Head of Performance and Sport Science for Major League Soccer (MLS) powerhouse, the Los Angeles (LA) Galaxy, began at a crossroads: pursue traditional coaching or medical pathways. As a soccer “Swiss Army knife,” he embraced early sport science alongside coaching, building a career defined by collaboration and innovation. At the Galaxy, Williams is part of a web of support that uses rich data storytelling tailored to stakeholders and players, guiding decisions and infusing value in every encounter. This system drives their three key pillars: winning championships — including their recent record-breaking sixth MLS Cup — developing a robust academy pipeline, and leading innovation. In MLS’s “cultural melting pot,” Williams balances diverse backgrounds and short-term demands like fixture congestion while employing sustainable long-term strategies. With a unique full-time cognitive department and creative approaches like dodgeball warm-ups, he combines trust and ingenuity to elevate performance and presents a blueprint for those exploring emerging sport science.
