and Arm Strength Purpose Statement Occupational health professionals consistently document the need for physical testing upon application for physically-demanding jobs. Decades of studies suggest that physical fitness screening prior to job selection decreases workplace injuries. Many of these studies prove specifically that a direct correlation exists between one’s strength and job performance. This case study examines such a claim. It is an analysis of the impact arm strength (ARM) and

performing 50 squats with a weight of 50 kilograms on the shoulders requires both attributes‚ 150 squats without weight requires more muscular endurance while the ability to perform a single squat with a weight of 200 kilograms depends on muscular strength. Different tests are used for assessment of these different components of musculoskeletal fitness. To determine the strongest person in the group‚ multiple factors needs to be taken into account‚ including age‚ height‚ gender‚
