The relationship between youth-fitness test items related to cardiorespiratory endurance and body composition and health outcomes is well established. Until recent years, the link between musculoskeletal fitness measures and health markers has been less conclusive. The information provided in this article offers evidence of the health links between youth musculoskeletal measures (specifically the grip test, the vertical jump, the long jump, and the plank) and health outcomes. While additional research is necessary, it is safe to say that the new research brings us closer than ever to identifying reliable, valid, practical muscle-fitness test items. Physical education teachers can consider the suggestions provided in this article for using the test items in their classes.
