relationship between reliability and validity

Other strength test methods include maximal repetitions to failure (MRF) (i.e., perform as many repetitions as possible at a certain absolute weight or a given percentage of body weight) and maximal isometric force (MIF).

1RM refers to the heaviest weight a person can lift with maximum effort in a single repetition while maintaining the correct lifting technique. The most widely used practical method to measure dynamic muscular strength is the one-repetition maximum (1RM) test. Strength capacity assessments are an integrated part of the training process to evaluate conditioning programs and analyze individual training and health status. Well-developed strength is also important for health, and daily-life well-being, as regular doses of strength training have been shown to decrease premature mortality, delay muscular atrophy processes, prevent osteoporosis, and reduce the risk of coronary heart disease and non-insulin-dependent diabetes. Muscular strength is a crucial determinant for varying measures of motor performance, including speed, agility, power, balance, coordination, flexibility, jumping and throwing ability.
