In its most basic form, strength and conditioning is the practical use of sports science to improve movement quality. It is founded on evidence-based research, exercise physiology, and anatomy. Because we all move, we can all benefit from improved movement quality. Strength and conditioning articles come in many forms. There are various types of strength training exercises available for improvement, ranging from simple body weight exercises to highly specialized techniques used by professional athletes. Weight machines are used to increase muscle strength, while resistance bands are used to improve flexibility and balance. Strength and conditioning coaches work with their athletes to determine goals, then design programs that will help the athletes reach these goals. They may also work with other members of the coaching staff (e.g., athletic trainers, physiologists) to ensure that their recommendations are effective and safe for their patients. Strength and conditioning coaches must have at least an undergraduate degree in physical education or kinesiology. They usually receive additional training through graduate programs in fitness management or sports science. The American Strength and Conditioning Association was formed in 1985 as a non-profit organization dedicated to promoting strength and conditioning research, educating professionals about strength training, and helping strength and condition coaches across the country. American strength and conditioning coaches must be certified by the ACCA to be recognized by their peers.
