Abstract

PurposeTo investigate the test-retest reliability and criterion validity of the Isometric Horizontal Push Test (IHPT), a newly designed test that selectively measures the horizontal component of maximal isometric force.

MethodsTwenty four active males with ≥ 3 years of resistance training experience performed two testing sessions of the IHPT, separate by 3-4 days of rest. In each session, subjects performed three maximal trials of the IHPT with 3-min of rest between them. The peak force outputs were collected simultaneously using a strain gauge, and the criterion equipment, consisting of a floor-embedded force plate.

ResultsThe test-retest reliability of peak force values was nearly perfect (ICC ∼0.99). Bland-Altman analysis showed excellent agreement between days with nearly no bias for strain gauge 1.2N (95% CI: -3, 6N) and force plate 0.8N (95% CI: -4, 6N). A nearly perfect correlation was observed between the strain gauge and force plate (r=0.98, p<0.001), with a small bias of 8N (95% CI: 1.2, 15N) in favor of the force plate. The sensitivity of the IHPT was also good, with SWC > SEM for both the strain gauge (SWC: 29N; SEM: 17N [95% CI: 14, 20N]) and the force plate (SWC: 29N; SEM: 18N [95% CI: 14, 19N]) devices.

ConclusionsThe high degree of validity, reliability and sensitivity of the IHPT, coupled with its affordability, portability, ease of use, and time efficacy, point to the potential of the test for assessment and monitoring purposes.
