30–15 Intermittent Fitness Test: A Systematic Review of Studies, Examining the VO₂max Estimation and Training Programming

This study presents an overview of current scientific articles that address the reliability and validity of the 30–15 intermittent fitness test (30–15 IFT) as an assessment of aerobic capacity, as well as its use in terms of training programming. The search for and analysis of papers was conducted in accordance with PRISMA guidelines. A database search was performed through PubMed, PMC, Med Line, Cochrane Library and ScienceDirect, as well as directly from the author who first presented the IFT 30–15. Type of study: research was included in this paper on condition that (i) the original scientific paper was available in its entirety; (ii) the IFT 30–15 was used to evaluate or verify validity and reliability; and (iii) the IFT 30–15 was used for the purpose of evaluation of training programming. Of the 213 relevant studies identified, 21 were included in the quantitative analysis. All research was conducted on a sample of athletes who are exclusively engaged in team sports. As for the use of the subject test when it comes to programming individualized intermittent training to strengthen aerobic capacity, it seems that the IFT 30–15 test is appropriate and extremely useful for team sports. Regarding the reliability of tests identified in the reviewed literature, all studies indicate that the 30–15 IFT is a reliable test for assessment of aerobic capacity
