|a The purpose of this study was to determine the accuracy of select repetitions-to fatigue equations to estimate one-repetition maximum (1RM) bench press strength for middle school-aged children. Seventeen girls and 21 boys between the ages of 11 and 12 years from 2 sixth grade physical education classes at the Doctor’s Charter School of Miami Shores volunteered to participate. Each student was assessed at least 3 times by the researcher. The assessments were composed of basic height and weight measurements, the horizontal chest press 1RM, and repetitions-to-fatigue. On separate days 1 week apart, children performed the 1RM test until a consistent maximal weight was lifted, and 1 week later they performed the repetitions-to-fatigue test. The average 1RM for our sample was 23.39 ± 5.32 kg, and the average number of trials to attain 1RM was 4. The correlation was significant, strong and similar for each of the Brzycki, Epley, and Landers equations (r = .954, SEE = 1.62, p < .001). In addition, there was a statistically significant difference between mean values for actual and each estimated 1RM (p < .001). The Epley equation produced the smallest mean difference (3.30 kg) between the actual and the estimated 1RM compared to the Brzycki (3.90 kg) and Landers (3.71 kg) equations. Furthermore, the Epley equation also produced the smallest total error. Although the correlations were significant, strong and similar, the paired t tests revealed significant (p < .001) underestimations of the 1RM by the Brzycki, Epley, and Landers equations. In conclusion, the three repetitions-to-fatigue equations underestimated the actual 1RM in this specific population; however, the Epley equation was the most accurate in estimating 1RM values for children aged 11 to 12 yr. Therefore, exercise professionals and physical education teachers might consider the Epley equation when estimating bench press 1RM values for this population. |
