Sponsor's own description
Muscle strength is important for health and can affect how well people live, even increasing the risk of death in adults and older people. The one-repetition maximum (1RM) test is relatively easy compared to other tests and is commonly used to measure muscle strength in various groups, including healthy individuals and those with chronic diseases. It assists in prescribing resistance training and understanding training results. Knee extensors, especially the quadriceps femoris, are often studied because they play a key role in standing and walking. However, there are no standard reference values or equations for measuring knee extensors using the 1RM test. The existing methods rely on the evaluator's judgment, making them hard to replicate and standardize. The goal of this study is to provide reference equations and values for the 1RM of knee extensors and to establish a standardized methodology for the test.
