pain, injury risk, and posture problems. Further, the committee found no evidence of adverse events observed in studies of flexibility, nor is there reported evidence of adverse events in field testing of flexibility using popular test items. With this in mind, the committee suggests that in schools and other educational settings, flexibility test items may be included to educate youth and their parents about flexibility as a component of overall musculoskeletal fitness, function, and performance. The selection of such a test should be based on its validity, reliability, and feasibility. To establish interim cut-points for such tests, the guidance provided in Chapter 3 of this report should be followed. Full recommendations on the use of these tests in schools and other educational settings are presented in Chapter 9.
