Use of the 7-10RM as a Predictor of 1RM Bench Press in Trained and Untrained College Males

Dr. Jerry Mayhew, Faculty Mentor

The purposes of this study were to evaluate the accuracy of predicting bench press strength from sub-maximal repetitions and to determine the accuracy of prediction on trained individual. Fifty, untrained college males where tested for the amount of weight with which they could perform 7-10 repetitions to muscular fatigue. The high correlation between 7-10 RM and the 1RM (r =.98) allowed the development for an accurate prediction equation (SEE = 4.1kg). The prediction equation was applied to a group following twelve week of resistance training. The cross-validation was not significantly different from the original group in age, height, weight or 1RM but used a significantly higher 7-10RM weight. The high cross-validation correlation (r =.91) and the non-significant difference between predicted and actual indicated that a single equation could be used to predict trained or untrained strength status.
