Although it may be possible to increase skeletal muscle levels of carnitine by combining it with relatively large amounts of carbohydrates repeatedly throughout the day, or by taking it with choline, there is limited data that shows that carnitine is a fat-burner that results in significant reductions in fat mass.

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.

For Keith Swift, coaching is completely effort based, but it starts with camaraderie and education. As Director of Strength and Conditioning at Wofford College, his philosophy is clear: educate, heal, and enhance. While playing collegiate football and studying exercise science, Swift learned early to question the “why” behind training and encourages his student-athletes to do the same. At an academically rigorous institution, his educational focus fits right in, fostering curiosity, technical precision, and peer coaching. Swift shares how his experiences across professional baseball, the private sector, and collegiate programs each shaped his foundation while making it his own. Amid collegiate challenges — from the National Collegiate Athletic Association (NCAA) transfer portal to the growing authority of student-athletes — Swift holds firm that “there is no substitute for hard work.” His goal is simple: help student-athletes leave with both a degree and a championship ring, setting them up for success in sport and life.
