Relationship of timed sit-up tests to isokinetic abdominal strength.

Article: Sit-up tests have been included in most youth and adult fitness test batteries. One logical reason for their inclusion is the possible relationship between poor abdominal strength and the incidence of low back pain. Therefore, a number of timed field tests have been proposed to measure abdominal function. However, the published data on the validity of field test measures are sparse. The sit-up test has been widely described as a test of abdominal muscular strength and endurance (DiNucci, McCune, &: Shows, 1990; Kendall &: McCreary, 1983; Kraus, 1965; Lipetz &: Gutin, 1970; Robertson &: Magnusdottir, 1987; Vmcent &: Britten, 1980).
