Elite sport often gets more attention, but youth training gives strength and conditioning coaches an earlier chance to build athletes’ competence and confidence. Kelli Brightwell specializes in youth development and brings more than a decade of sports training experience, including four years at Michael Johnson Performance. Brightwell defines peak height velocity as the period during which height increases fastest. She then explains why its timing can differ among teammates of the same age. So what should strength coaches test, and what do the results mean? The answer changes with each athlete’s maturity and training experience. Brightwell addresses the growth-spurt “awkward phase,” when familiar movement patterns can break down as an athlete adjusts to a changing body. She also considers how sport sampling can expand children’s range of physical skills and help them discover what they enjoy. Learn how maturation can affect movement, testing, and programming — and why young athletes need foundations before specialization.
