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

Abstract

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.

The reliability, validity and usefulness of the 30–15 intermittent fitness test for cardiorespiratory fitness assessment in military personnel

“…Besides the reliability and the validity, the information on usefulness of the 30-15 IFT test will allow sports scientist to make firm conclusion about whether the changes observed in response to strength and conditioning programming intervention are important or not 24 . Our results showed good usefulness rating for ERS IFT, which is in good agreement with previous findings 28,[31][32][33] . For example, for ERS IFT, SWC was found to be marginal (SWC = 0.20 km/h, TE = 0.56 km/h), marginal (SWC = 0.20 km/h, TE = 0.31 km/h) and ok (SWC = 0.34 km/h, TE = 0.32 km/h), in female basketball players 32 , female football players 27 and male futsal players 31 , respectively.…”

The Relationship Between Jump Performance, Speed and Cod Speed in Elite Female Soccer Players

“…Comprehending the physical qualities that could mostly influence COD ability improvements over shorter and longer distances could highlight training efficiency (Lockie, Post, & Dawes, 2019). It is of big importance to consider specific movement patterns before making a training program for team sport athletes (Stanković et al, 2021), in particular those that include eccentric exercises, acceleration and deceleration efforts, which can include specific for COD drills.…”

The soccer season: performance variations and evolutionary trends

“…Additionally, a positive relationship was observed between team success in the league and the Yo-Yo intermittent endurance test level 2 (YYIE2) ( Randers, Rostgaard & Krustrup, 2007 ) and the Yo-Yo intermittent recovery test level 2 (YYIR2) ( Ingebrigtsen et al, 2012 ). Several studies reported significant correlations between the performance on distinct intermittent endurance field tests and other physiological and performance measurements, such as VO 2max ( Castagna et al, 2006 ; Jones et al, 2013 ; Krustrup et al, 2006 ; Rampinini et al, 2009a ; Rampinini et al, 2009b ; Stanković et al, 2021 ; Wells et al, 2014 ), VO 2 kinetics during high-speed running (HSR) ( e.g ., velocity at 80%∆VO 2 ) ( Wells et al, 2014 ), incremental treadmill test performance (ITT) ( Krustrup et al, 2006 ), and TE during a maximal anaerobic running test ( Wells et al, 2014 ). Moreover, improvements in the YYIR2 were associated with increases in power, TE and maximal speed during a maximal anaerobic running test ( Wells et al, 2014 ).…”
