The validity and reliability of a 1-minute half sit-ups test

The purpose of this study was to investigate the validity and reliability of a 1-minute half sit-up test to allow for its implementation as a test of abdominal strength and endurance. Subjects (N= 133) performed as many sit-ups as they could in one minute. A test-retest reliability study was conducted for two measuring devices, in which subjects performed the sit-ups twice using the same apparatus. An inter-apparatus reliability study between the two apparatus was conducted, in which subjects performed the sit-ups once for each measuring device. Results showed very high test-retest reliability for both measuring devices and high inter-apparatus reliability. A validity study was conducted in which the subjects performed the half sit-ups test, the current YMCA full sit-ups test (concurrent validity), and a test of isometric abdominal strength (face validity). Concurrent validity was moderately high and face validity was moderate. The results allow for the inference that the half sit-ups test is a valid and reliable measure of abdominal strength and endurance. (Abstract shortened by UMI.).
