Having been said that, 1RM measurement requires a long period of testing to have a consistent value; it also requires familiarization technique which is also very intense and extensive procedure. To avoid the risk, related to the measurement of 1RM, many studies have been conducted to produce regression equations for predicting 1RM strength. There are other studies too that have been undertaken to determine the accuracy of such equations. Prediction of 1RM strength allows an exercise specialist to assess an individual's maximal lifting capacity without subjecting the novice lifter to the increased risk associated with a 1RM lift. The advantage of calculating 1RM using the formula is that, it provides the therapist with the most widely accepted measure of strength without the risks associated with the formal 1RM testing. However the 1RM load lifting also requires great concentration and considerable mental preparation for the subject which can be an extremely intense experience that leaves them unsure and scared. Although there is no real data concerning the risk of injury in this test, the potential risk may be significantly increased by using very heavy loads.
