This review aimed to synthesize previous findings on the test–retest reliability of 30–15 Intermittent Fitness Test (IFT). The literature searches were performed in 8 databases. Studies that examined IFT and presented intraclass correlation coefficient (ICC) and/or variation (CV) for maximal velocity peak heart rate included. consensus-based standards selection health measurement instruments (C...

The problem of estimating closeness between the distributions of S/B and Z was studied by many authors in various directions (see, for instance, [1, 2]). In the present article we obtain estimates for the difference ∆ = |S/B − Z| (1.4) under the assumption that the random variables S and Z are realized in a special way on a common probability space. We prove among other results that, with S and...
