Description
Accurate estimation of the strength of a muscle or muscle group is of particular importance in the development of exercise prescriptions and training regimens. Previous researchers have developed sub-maximal testing protocols and equations to avoid requiring a 1-Repetition-Maximum (I-RM) performance from a subject or patient in order to reduce the potential risk of injury. However, little research has been done to cross-validate these sub-maximal tests. Therefore, our purpose is to compare the direct 1-RM method of maximal strength determination to the indirect 1- RM (curvilinear) method and the indirect I-RM (linear) method. Approximately 40 college-age male and female volunteers will serve as subjects for this investigation. Each subject will initially perform the direct 1-RM test for determination of maximal bench press strength; this will serve as the control value. The subjects will be randomly assigned into one of two groups. After a minimum of 3 days rest, the subjects of group 1 will be tested using sub-maximal protocol 1 (curvilinear l-RM), and following another minimum of 3 days of rest, they will tested using sub-maximal protocol 2 (linear 1-RM). Group 2 will be tested in the opposite manner. We speculate there will be no significant difference between the sub-maximal (indirect) protocols and the direct I-RM method of maximal strength testing.
