A dynamic isotonic muscle contraction (ITMC) causes joint movement and excursion of a body segment as the muscle contracts and shortens or lengthens under tension. One repetition maximum (RM) is defined as the maximum weight a person can lift only once in a complete range of motion. It is a gold standard for measuring muscular strength therefore it is used for most of the strength training programmes. The 1RM test has been shown to be reliable in various populations. Further, setting an intensity of resistance training based on a percentage of the 1RM has been found to be effective for improving outcomes such as muscle strength, muscle power, and muscle hypertrophy. Many studies have shown increase in strength when RM testing is repeated over several days to weeks. Therefore, most testing protocols suggest that strength should be measured more than once; typically 2 or 3 testing sessions is recommended.
