"Training is a process and there's a lot more to it than simply sets and reps." Respected strength coaches Mike Stone and Meg Stone discuss periodization and programming for strength power athletes at the 2012 NSCA Coaches Conference.

For decades, most scientists and practitioners have agreed that muscle hypertrophy also induces strength gains. However, a recent publication "The Problem of Muscle Hypertrophy: Revisited," questioned the mechanistic role that exercise-induced increases in muscle size have on the exercise-induced increases in strength (of force production), as well as the influence that exercise-induced increases in strength have on sports performance. Such suggestions undermine the important of certain aspects of strength and conditioning for sport. Specifically, if not acting as a mechanism for strength adaptation, it is unclear if there is a sports-related benefit to skeletal muscle hypertrophy. In addition, the authors argued that if strength has little impact on sports performance, strength and conditioning programs may be doing little more than delaying recovery from practicing the actual sport. This contention also indicates that hypertrophy should be avoided in nearly all scenarios because increased muscle size would be additional mass that must be overcome. The purpose of this special discussion is to allow for an in-depth scientific discussion of the experimental evidence for and against the position of Buckner et al. That exercise-induced increases in muscle size have little relevance on the exercise-induced increases in strength and thus, sport performance.

This study was designed to provide an overview of weightlifting performance as a function of age group and sex and evaluate the potential of countermovement jump height (CMJH) as a tool to gauge performance potential. Data from 130 youth athletes (female, n = 65 & male, n = 65) were used to examine progression of performance (Total and Sinclair total) and the relationship between CMJH and Sinclair total while considering interactions between CMJH and age and/or sex. ANOVAs with post hoc analyses revealed that both totals had a statistical first-order polynomial interaction effect between age group and sex and the difference between age groups of 12–13 and 14–15 years old was statistically greater for male than female. A linear model, developed to examine the relationship, revealed that CMJH and CMJH x sex x age rejected the null hypothesis. Our primary findings are that male youth weightlifters have a higher rate of performance progression, possibly owing to puberty, and CMJH may be a better gauging tool for older male youth weightlifters.
