The Marine Corps utilizes a three-event Physical Fitness Test (PFT) comprised of a 3-mile run, sit-ups, and pull-ups to assess the level of physical fitness of individual Marines. This thesis uses newly collected data from the Marine Corps to analyze the current weight and body-fat standards and compare them with proposed alternatives. The research investigates whether the current standards can be slightly relaxed without resulting in significant decreases in physical fitness performance. Additionally, this thesis investigates the validity of pull-ups as an indicator of muscular strength and endurance. The analysis compares the performance scores for two types of pull-ups (the dead- hang and kip methods) with other physical performance events which require upper body strength and muscular endurance. The thesis also presents proposed scoring alternatives for the pull-up event based on an analytical comparison of performance distributions for the run and sit-up events, in order to level the equality for all three PFT events. Additionally, a new 3-profile PFT alternative comprised of aerobic, muscular, and body-fat profiles is presented as an improved measure of assessing the physical fitness of individual Marines.
