Herbs, spices, and other whole foods contain bioactive substances that can purportedly improve health and performance in a variety of ways from increased metabolism, antioxidant activity, gastrointestinal health, greater neurotransmitter production, and more. In this session from the NSCA 2015 Personal Trainers Conference, Dr. Carwyn Sharp describes and defines nutraceuticals and functional foods, issues of potency and standardization, their potential uses for health and performance, future directions, and current trending products.

This excerpt from Strength Training describes the hormone response to exercise and their functions within the human body.

This article aims to discuss concurrent activation potentiation (CAP) and the proposed mechanisms underlying it, summarize the available research examining the phenomenon, and provide strategies for its implementation.

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.

Learn how strength and power training can help your clients boost production of the hormones that many consider to be the “fountain of youth.”

Dietmar Schmidtbleicher, Head and Chair for Sport Sciences at the Institute of Sport Sciences at the Goethe University Frankfurt/Main in Frankfurt, Germany—and one of the world’s leading experts on strength and power training—explains the influencing factors of force production in eccentric muscle actions. Schmidtbleicher made a rare appearance in the United States at the NSCA’s 2015 National Conference.

In this session from the 2017 Coaches Conference, Joe Eisenmann explains the three major energy systems in the human body, identifies appropriate tests of physical work capacity, and explains how to design programs that maximize energy production and fatigue resistance in sports.

This excerpt from NSCA's Guide to Tests and Assessments briefly discusses the method behind a lactate threshold test and the pretest considerations one might take prior to this test.

By adhering to the basic principles of training, including progressive overload, periodization, and a safe lifting environment, the bilateral deficit can be improved by the amalgamation of unilateral force production, maximal effort, and repeated effort training.

Supplements that claim to boost nitric oxide have not been proven to be all that effective since the actual conversion in the blood cell is rather complicated and requires oxygen, which is usually in short supply during exercise or at high altitude. So how does an athlete boost their nitric oxide production?
