Modern wearable devices such as heart rate (HR)/ECG monitors, 3D gyroscopes and spirometers provide additional options for these testing methods. In comparison to standard laboratory testing, field test methods have been developed to bring exercise testing to a more realistic setting with the additional practical benefit to determine exercise capacity also in groups ( Krustrup et al., 2003). Today, Yo-Yo test variants are extensively used to assess physical fitness in different sports and populations. Since the introduction of the Yo-Yo Intermittent (YYI) test as a field test method in the 1990s, an evolution of the Yo-Yo test family has occurred ( Bangsbo, 1994 Krustrup et al., 2003 Bangsbo et al., 2008). For each separate test, reference values (global means and percentiles) for sports at different levels and both genders were calculated.Ĭonclusions: Our analysis provides evidence that Yo-Yo intermittent tests reference values differ with respect to the type and level of sport performed.The presented results may be used by practitioners, trainers and athletes to rate Yo-Yo intermittent test performance levels and monitor training effects. The Yo-Yo test types most frequently used were the Yo-Yo Intermittent Recovery Level 1 (YYIR1, 57.7%), the Yo-Yo Intermittent Recovery Level 2 (YYIR2, 28.0%), the Yo-Yo Intermittent Endurance Level 2 (YYIE2, 11.4%), and the Yo-Yo Intermittent Endurance Level 1 (YYIE1, 2.9%) test. Results: 248 studies with 9,440 participants were included in the structured analysis. Sub-maximal test versions and the Yo-Yo Intermittent Recovery Level 1 Children's test (YYIR1C) were not included. Original reports on healthy females and males ≥16 years were eligible for the analysis. Methods: A systematic literature search for articles published until August 2017 was performed in MEDLINE, Web of Science, SPORTDiscus and Google Scholar. This systematic review of the most common Yo-Yo tests aimed to provide reference values for test results by statistical aggregation of published data.
