Abstract: PURPOSE: To assess how accurately trained subjects can predict exercise endpoint in resistance training.METHODS: 12 female (age 20.33 ± 1.61 years; height 166.12 ± 3.95 cm; weight 69.99 ±9.76 kg) and 12 male (age 22.17 ± 1.40 years; height 176.83 ± 8.78 cm; weight 82.12 ± 12.91 kg) resistance trained subjects were tested for their one repetition maximum (1-RM) in bench press, and then performed four sets to failure with 65% of 1-RM.Prior to each set subjects predicted how many repetitions they could complete.After each set subjects reported a rating of perceived exertion (RPE) using the 10-point resistance training RPE scale.A repeated measured ANOVA was used to determine differences between predicted and actual repetitions-to-failure.Dependent ttests were used to analyze differences for each set separately.Spearman's rank correlation was used to determine the relationship between RPE, predicted and actual repetitions-to-failure.RESULTS: The repeated measures ANOVA indicated no significant difference between predicted and actual repetitions-to-failure for both genders (p > .05).Significant differences were found across sets for both genders (p < .05).Dependent t-tests showed no significant differences between predicted and actual repetitions-to-failure in the last two sets for both genders and in the first set for males (p iii > .0125).Significant differences were found in the first two sets for females and the second set for males (p < .0125).No significant correlations were found between predicted repetitions-to-failure and RPE in females (p > .05),but in males a negative correlation was present (r = -.538;p < .05:).A negative correlation was found for both females (r = -.351;p = .014)and males (r = -.458;p = .001)between actual repetitionsto-failure and RPE.Significant correlations were found between predicted and actual repetitions-to-failure for females (r = .851;p = .000)and males (r = .932;p = .000).(DISCUSSION: Subjects were more accurate in predicting repetitions-to-failure in the last two sets.This can be due to a learning effect, or how many less repetitions were possible due to acute fatigue, making it easier to predict.CONCLUSION: It may be possible to regulate resistance training intensity using a predicted exercise endpoint, but further research is needed.
