Early sport specialization involves physically immature children participating in intensive year-round training and/or competition for a single sport. The lack of sport exposure and diversification during the developmental years may underlie the increased risk of overuse injuries, blunting of motor skill development, psychosocial issues, overtraining syndrome, burnout, and potential dropout from sport. With increasing number of youth choosing, or being encouraged, to specialize at an early age, we aim to provide evidence based recommendations for the integration of strength and conditioning into the development programs of young athletes who participate in sports with a culture of early specialization. In addition to the principles of programming, strategies are provided relative to monitoring of growth, maturation, and training load to illustrate the potential complexities of attempting to optimize long-term athletic development in early specializing athletes.

Dr. Whitney Moore and Val Smith from Wayne State University use this session, from the 2019 NSCA National Conference, to provide evidence-based motivational strategies and leadership behaviors, strength coach tested relationship-building strategies, and explain different levels of informal leadership training opportunities

In this video from the 2023 NSCA National Conference, Duncan French discusses effective decision-making processes within strength and conditioning, and how coaches can identify, review, and improve training interventions for strength, power, and conditioning.

The NSCA offers an Exam Prep Live Clinic for individuals preparing for the Certified Strength and Conditioning Specialist (CSCS) exam. The CSCS Exam Prep Live Clinics are offered in three formats: 2-Day and 3-Day options with a blend of classroom lecture and hands-on training. Additional Clinics are added to the calendar every 2-3 months.

Tex McQuilkin, Director of Training for Power Athlete HQ, defines athleticism as a trainable performance variable at the 2019 Coaches Conference. McQuilkin illustrates the four phases of the competitive lifecycle for sport athletes and empowers coaches with strategies to best apply progressive overload and support the long-term trainability of novice athletes.

The 3-minute all-out exercise test (3MT) was developed over a decade ago and enables the estimation of time for onset of momentary fatigue for a given speed or power output exceeding critical speed (CS) or critical power (CP), respectively. The 3MT has been validated for conducting high-intensity interval training, used with load carriage prediction and prescription, and validated for shuttle running. These prescriptions are novel because they allow for standardizing exercise intensities relative to metabolic parameters as opposed to a percentage of a given maximum or reserve. Research was identified using leading search engines (e.g., PubMed, Google Scholar, and Research Gate) and citations to similar articles. The objective of this review article was to summarize research that emerged on the CS/CP concept with emphasis on applications since the advent of the 3MT. The review concludes with application of the CS/CP concept to the frequency, intensity, time, and type of exercise for exercise prescription.
