The aim of this study was to evaluate the application of the Yo‐Yo intermittent endurance test level 2 (Yo‐Yo IE2) to elite female soccer populations. Elite senior (n = 92), youth (n = 42), domestic (n = 46) and sub‐elite female soccer players (n = 19) carried out the Yo‐Yo IE2 test on numerous occasions across the season. Test–retest coefficient of variation (CV) in Yo‐Yo IE2 test performance in domestic female players was 4.5%. Elite senior female players' Yo‐Yo IE2 test performances were… 

The Yo-Yo IE2 test: physiological response for untrained men versus trained soccer players.

The Yo-Yo IE2 test was shown to possess high construct validity by showing large differences in performance, HR, and anaerobic metabolism between UTR and TR.

The Yo-Yo Intermittent Endurance Level 2 Test: Reliability of Performance Scores, Physiological Responses and Overload Characteristics in Competitive Soccer, Basketball and Volleyball Players

The results suggest that the Yo-Yo IE2 test appears to be a reliable alternative for evaluating the ability to perform intermittent high-intensity running in different outdoor and indoor team sports and players may need one or two familiarization tests to ensure valid assessment of intermittent endurance capacity.

Yo-Yo intermittent recovery test level 2: Cardiorespiratory response and performance in professional soccer players, comparison between under 20 and over 20 years old players

Only in the U20 group, a significant correlation between the variables oxygen uptake in the ventilatory threshold (VO2atVT) and performance in the test (Dmax), VO2 at VT and maximum speed (Smax), peak oxygen uptake and Smax and VO2peak and Dmax was observed.

Contrasts in intermittent endurance performance and heart rate response between female and male soccer players of different playing levels

The gap between competitive levels among female soccer players is greater than that observed for male players in intermittent endurance performance and submaximal HR response, as well as their relationship, by sex and competitive level in soccer.

Reliability and validity of Yo-Yo tests in 9- to 16-year-old football players and matched non-sports active schoolboys

Yo-Yo intermittent test performances and HRpeak are reliable for 9- to 16-year-old footballers and non-sports active boys, providing evidence of construct validity and intraclass correlation coefficient values for test–retest were excellent in both groups.

Yo-Yo intermittent recovery test performances within an entire football league during a full season

YIR performances are highly variable within a football league over a season and are influenced by league ranking, regularity of competitive play and playing position.

Reliability and Construct Validity of Yo-Yo Tests in Untrained and Soccer-Trained Schoolgirls Aged 9-16.

The Yo-Yo tests are reliable for determining intermittent-exercise capacity and %HRpeak for soccer players and untrained 9- to 16-year-old girls and possess construct validity with better performances for Soccer players compared with untrained age-matched girls.

Reliability, Validity and Usefulness of 30–15 Intermittent Fitness Test in Female Soccer Players

The findings suggest that the 30–15IFT is a valid and reliable intermittent aerobic fitness test of elite female soccer players and provided practitioners with evidence to support the accurate detection of meaningful individual changes in VIFT of 0.5 km/h (1 stage) and HRpeak of 2 bpm.



The Yo-Yo IR2 test: physiological response, reliability, and application to elite soccer.

The Yo-Yo IR2 test was shown to be a sensitive tool to differentiate between intermittent exercise performance of soccer players in different seasonal periods and at different competitive levels and playing positions and can be used to evaluate an athlete's ability to perform intense intermittent exercise with a high rate of aerobic and anaerobic energy turnover.

Game-Induced Fatigue Patterns in Elite Female Soccer

The study demonstrates that the type of fatigue that occurs after a female soccer game does cause marked impairment in intense intermittent exercise and repeated sprint performance but does not affect vertical jump performance, and support the notion that decrements in distance covered by sprinting and high-speed running toward the end of elite female games are caused by fatigue.


The Yo-Yo test and not the 12MRT can discriminate endurance performance in experienced elite level soccer referees and may be considered a relevant field test to assess endurance preparedness for experienced football referees and a useful tool in talent selection.

Physical demands during an elite female soccer game: importance of training status.

It is demonstrated that all players have high HR throughout a competitive game with periods of near-maximal values, the distance covered by HIR during match play is closely related to the physical capacity, and the Yo-Yo intermittent recovery test can be used as an indicator of the physical match performance of elite female players.

Fitness determinants of success in men's and women's football

Results show major fitness differences by gender for a given competitive level in football players, and it is suggested that training and talent identification should focus on football-specific endurance and agility as fitness traits in post-adolescent players of both sexes.

The yo-yo intermittent recovery test: physiological response, reliability, and validity.

The Yo-Yo intermittent recovery test was a valid measure of fitness performance in soccer and had a high reproducibility and sensitivity, allowing for detailed analysis of the physical capacity of athletes in intermittent sports.

Performance enhancements and muscular adaptations of a 16‐week recreational football intervention for untrained women

Recreational women's football leads to significant increases in VO2max, performance and muscular adaptations throughout a 16‐week training period, indicating that football can be used as an activity to elevate the physical capacity of untrained women.

Match performance of high-standard soccer players with special reference to development of fatigue

Top-class soccer players performed more high-intensity running during a game and were better at the Yo-Yo test than moderate professional players; fatigue occurred towards the end of matches as well as temporarily during the game, independently of competitive standard and of team position; defenders covered a shorter distance in high- intensity running than players in other playing positions.

The Yo-Yo Intermittent Recovery Test

The Yo-Yo IR tests provide a simple and valid way to obtain important information of an individual’s capacity to perform repeated intense exercise and to examine changes in performance.

Aerobic Capacities and Anthropometric Characteristics of Elite Female Soccer Players

The present results suggest that few anthropometric and physiological differences exist between playing positions in elite female soccer players and recommend regular testing programs to be able to construct and implement tailored training programs for players' physical capacities with respect to the demands of their playing positions.
