Harty, Baylor A. Johnson, Jacob R. Dellinger, Marqui L. Benavides, Bradley Vincent, Abegale D. Williams, Sarah J. White, Grant M. Tinsley

International Journal of Exercise Science: Conference Proceedings

Two critical components of muscular performance are muscular strength (e.g., the maximal load that can be lifted for a given exercise) and muscular endurance (e.g., the maximal number of repetitions that can be performed at a given load). When seeking improvements in muscular performance, it is common to employ nutritional strategies that create an energy surplus and a resultant gain in body mass. Varying rates of body mass gain are often prescribed to optimize training adaptations, including improvements in muscular performance; however, the relationship between rate of body mass gain and muscular performance improvements, if any, is not entirely clear. …
