This study was done to determine the accuracy of 7 equations for predicting a 1-RM from repetitions to fatigue for the bench press, squat, and deadlift. Subjects, 67 untrained college students (40 M, 27 F) who were enrolled in weight training classes, participated in four 45-min practice sessions to learn proper lifting technique and determine the amount of weight to lift for the 1-RM test. All correlation coefficients between predicted and achieved 1-RM lifts were high (r > 0.95). For the… Expand
Validation of Submaximal Prediction Equations for the 1 Repetition Maximum Bench Press Test on a Group of Collegiate Football Players
The accuracy of 11 prediction equations in estimating the 1 repetition maximum (1RM) bench press from repetitions completed by collegiate football players using 225 lb. Expand
Development of prediction models to estimate 1-RM for upper and lower body exercises in non-resistance trained women
PURPOSE: The purpose of this investigation was to develop and validate a one-repetition maximum (1-RM) prediction model for the upper and the lower body in non-resistance trained women. METHODS:Expand
Reliability and Validity of the Load–Velocity Relationship to Predict the 1RM Back Squat
The load–velocity relationship 1RM prediction method used in this study cannot accurately modify sessional training loads because of large V1RM variability, and could not accurately predict 1RM, which was stable between trials. Expand
Using Squat Testing to Predict Training Loads for Lower-Body Exercises in Elite Karate Athletes
The 6RM squat load was a significant predictor for deadlift, leg press, lunge, and step-up and can be used as a time effective and accurate method to predict training loads for both bilateral and unilateral lower-body exercises with quadriceps as the prime mover. Expand
Establishment of the Prediction Equations of 1RM Skeletal Muscle Strength in 60- to 75-Year-Old Chinese Men and Women.
The equations can be used to predict 1RM from submaximal skeletal muscle strength accurately for older adults, and correlated significantly to the predicted 1RM obtained from the equations. Expand
Accuracy of Seven Equations for Predicting 1-RM Performance of Apparently Healthy, Sedentary Older Adults
Comparison of relative accuracy, similarity, and average error of 7 prediction equations for estimating 1-repetition maximum (1-RM) performance of older sedentary adults using Hammer Strength Iso-Lateral resistance exercise machines showed improved significantly and gender differences were minimal when RTF £ 10.

The validity of RTF to adequately estimate 1RM over a wide range of repetitions and within different exercises in trained, older female subjects was supported. Expand
The validity of submaximal ratings of perceived exertion to predict one repetition maximum.
Evidence is provided that submaximal ratings of perceived exertion can be used to provide reasonably accurate estimates of 1-RM in young and active men and women using the Borg 6-20 RPE Scale. Expand
1RM prediction: a novel methodology based on the force–velocity and load–velocity relationships
The use of the proposed force–velocity-based method (FVM) as a valid alternative to other indirect approaches for 1RM prediction is suggested. Expand
A Modified YMCA Bench Press Test as a Predictor of 1 Repetition Maximum Bench Press Strength
Using both fast and slow cadences, the YMCA bench press test can provide a valid estimation of 1RM performance in untrained young men and women. Expand
