Single-sport specialized training has led to an emerging risk of overuse injury and burnout. Here are nine things coaches and parents can do to minimize the risk of injury in youth athletes.

The catecholamines—primarily epinephrine, but also norepinephrine and dopamine—are secreted by the adrenal medulla and are important for the acute expression of strength and power because the hormones act as central motor stimulators and peripheral vascular dilators to enhance enzyme systems and calcium release in muscle.

By understanding the means by which athletes encounter risk, strength and conditioning professionals can integrate exercise programs that may offset one of the steps toward injuries.

This excerpt from NSCA’s Essentials of Sport Science highlights the importance of quantifying training load for both programming and monitoring an athlete’s progression or regression over time.

Alex Calder, Head of Sports Science for the Houston Dynamo Major League Soccer (MLS) team, talks to the NSCA Coaching and Sport Science Program Manager, Eric McMahon, about sports science data driving better decisions on and off the field. Topics under discussion include the importance of traditional strength training for soccer players, as well as, the variety of strength and conditioning opportunities there are to gain experience from at the high school, college, private, and professional level of sports.

Knowledge of metabolic rate can help athletes as well as health-conscious people improve their exercise performance or obtain the fat-to-lean-mass ratio optimal for their personal situations. Two examples of how this works follow.

In this NSCA 2018 Coaches Conference video, Chris Bellon discusses integrating periodization for speed, power, and strength development for collegiate athletes.

Brad Schoenfeld, MS, CSCS, CSPS, NSCA-CPT, spoke at the NSCA's 2012 National Conference on optimizing the fat-burning effects of metabolic resistance training.
