Test-retest reliability of the 30-15 Intermittent Fitness Test: A systematic review.

ABSTRACT:

Purpose

This review aimed to synthesize previous findings on the test-retest reliability of the 30-15 Intermittent Fitness Test (IFT).

Methods

The literature searches were performed in 8 databases. Studies that examined the test-retest reliability of the 30-15 IFT and presented the intraclass correlation coefficient (ICC) and/or the coefficient of variation (CV) for maximal velocity and/or peak heart rate were included. The consensus-based standards for the selection of health measurement instruments (COSMIN) checklist was used for the assessment of the methodological quality of the included studies.

Results

Seven studies, with a total of 10 study groups, explored reliability of maximal velocity assessed by the 30-15 IFT. ICCs ranged from 0.80 to 0.99, where 70% of IC
