A master’s degree in exercise science is the in-depth study of applied human physiology and its relationship with sports, fitness, nutrition, health, and overall wellness. These programs usually last about two year. Within your Master of Science (MS) degree, you not only hone your knowledge of athletic training but you also specialize in an area that interests you, such as strength and conditioning, sports nutrition, performance enhancement, psychobiology of exercise, sports psychology, and wellness and fitness. Each university offers a list of program concentrations. When you complete your degree, you may undertake leadership responsibilities within your workplace.
