1rm Prediction and Load-velocity Relationship

INTRODUCTION Maximal strength is often estimated using the force-endurance relationship, where tables or formula are used to predict one repetition maximum (1RM) or other loads (e.g. 3RM loads). For some populations (for example the frail or very young) such a procedure may not be appropriate and the accuracy of these methods depends on several parameters such as the number of repetitions, type of exercise, training background and the population used (1). Very recently, 1RM estimation from a loadvelocity profiling protocol has been presented (2, 3). The aim of the present study was to investigate the ability of the load-velocity relationship to predict 1RM in different strength exercises and with different assessment devices.
