The purpose of this study was to evaluate the effectiveness of repetitions to fatigue (RTF) for estimating one-repetition maximum (1-RM) bench press performance in male high school athletes. Members of high school athletic teams (N = 213, age = 16.3 ± 1.1 yrs, weight = 79.9 ± 16.7 kg) from four states were tested for 1-RM bench press and RTF after completing 4–6 weeks of resistance training. A new equation for use with male high school athletes was developed from a random sample of 180 participants; it appears to have excellent predictive potential (r = 0.96, SEE = 4.5 kg) and cross-validated well on a subsample (n = 33) from this population (r = 0.98, t = 0.64). Therefore, RTF can be used with acceptable accuracy to estimate maximal strength in the majority of adolescent male athletes who need to handle excessively heavy weights.
