Abstract and Figures

Yo-Yo intermittent tests are often used to assess physical fitness in a range of sports and scientific projects. The Yo-Yo intermittent recovery test, in particular, was a reliable indicator of fitness level in terms of total distance covered in meters, maximum oxygen consumption in VO2 Max, and levels achieved. The purpose of the research is to examine the aerobic endurance fitness of women cricket bowlers and batters using the Yo-Yo Intermittent Recovery test level 1. The capacity to perform intervals repeatedly over an extended length of time was measured in this study. A total of 60 female cricket players were chosen for this study. Out of these, 30 were bowlers, while the other 30 were batters. On these, the YYIRT 1 test was run. The test was carried out until the subject was able to do so, until the beep rang, or if the subject received two warning signals at once for failing to reach the endpoint. Total distance covered and VO2 max were evaluated as outcome measures to compare two groups of batters and bowlers according to their respective playing positions. This study demonstrated that there is a significant difference in performance, i.e., total distance covered, levels reached, and VO2 max, between batters and bowlers.

Abstract
Yo-Yo intermittent tests are often used to assess physical fitness in a range of sports and scientific
projects. The Yo-Yo intermittent recovery test, in particular, was a reliable indicator of fitness level in
terms of total distance covered in meters, maximum oxygen consumption in VO2 Max, and levels
achieved. The purpose of the research is to examine the aerobic endurance fitness of women cricket
bowlers and batters using the Yo-Yo Intermittent Recovery test level 1. The capacity to perform intervals
repeatedly over an extended length of time was measured in this study. A total of 60 female cricket
players were chosen for this study. Out of these, 30 were bowlers, while the other 30 were batters. On
these, the YYIRT 1 test was run. The test was carried out until the subject was able to do so, until the
beep rang, or if the subject received two warning signals at once for failing to reach the endpoint. Total
distance covered and VO2 max were evaluated as outcome measures to compare two groups of batters
and bowlers according to their respective playing positions. This study demonstrated that there is a
significant difference in performance, i.e., total distance covered, levels reached, and VO2 max, between
batters and bowlers.

Introduction
One of the most significant topics in contemporary sports is the evaluation of athletes' physical
capabilities. Field and laboratory tests are used by coaches and sport scientists to screen
applicants, make selections, or assess the effectiveness of training program [1]. Many field tests
have been created to evaluate an athlete's physical capabilities. Due to its specificity and
usefulness, yo-yo tests have quickly become one of the most thoroughly researched shuttle run
tests in sports science [2]. It is believed that yo-yo tests are one of the most efficient field-based
methods for evaluating the endurance performance of soccer players. These tests have also
been used to evaluate players' abilities to repeatedly perform high-intensity exercise in many
team sports, including soccer, cricket, basketball, and rugby [3], [3]- [6]. This test estimates one's
maximum level of aerobic endurance [3]. The Yo-Yo Intermittent Recovery Test Level 1, often
known as YYIRT1, IR1, or something similar, is the most widely used version of the yo-yo
test despite the fact that there are many other variations [7]. The Yo-Yo IR level 1 (Yo-Yo IR1)
test measures the ability to engage in intermittent activity that activates the aerobic system to
its fullest extent [4].
It was developed to gauge a person's personal aerobic capacity by measuring their VO2 Max,
or the maximum or ideal rate at which their heart, lungs, and muscles can efficiently utilize
oxygen during exercise. It has been one of the most often utilized aerobic field tests since that
time. As a result, this predicts VO2 Max across athletes who compete at different levels of
competitiveness and in different sports [8].
In the early years of cricket and even only a few years ago, endurance was a factor that was
frequently overlooked. However, many later understood how crucial it is, particularly in
cricket formats like ODI and Test. These kinds of tests assist coaches in determining which
athletes need to improve their endurance. Currently, the Yo-Yo Intermittent Recovery (IR)
Test is utilized to evaluate the endurance capabilities of female cricket players. By correctly
comprehending the test, practicing intermittent running, doing weight training, and engaging
in high-intensity interval training, one may do well and get better results on the YYIR test

level 1. Weekly test sessions and technical training for the
beep-sound shuttle run will also aid to increase physical
prowess, physical fitness, and mental alertness. The level 1
Yo-Yo intermittent recovery test is useful for assessing a
person's sensitivity to training as well as their various physical
capacities [9]. Therefore, the purpose of this study was to
evaluate the level 1 Yo-Yo Intermittent Recovery Test results
for the aerobic endurance fitness of female cricket bowlers
and batters.
Methodology
a) Selection of Subjects: For the purpose of the study, sixty
(N=60) female cricket players of 16 to 27 years of age
who had participated at least at the Division level were
chosen. Two groups of 60 Cricket players were formed
i.e. One group consists of thirty (N1=30) bowlers and
other of thirty (N2=30) batters. According to local
legislation, all participants had formal medical clearance.
All participants and parents gave their verbal and written
permission after being informed of the study's possible
dangers and experimental methodology. It was made
clear to participants that they might leave the research at
any moment without incurring any penalties.
b) Variables Selected: In consultation with experts, a
feasibility analysis was made to determine which
variables or skills could be used for the investigation
while taking into account the availability of tools, the
suitability of the subjects, the legitimate time that could
be devoted to tests, and to keep the entire study unitary
and integrated. The Yo-Yo Intermittent Recovery Test
Level 1 (YYIRTL1) was chosen for the current
investigation keeping in mind the aforementioned
requirements.
c) Equipment Required
Flat, non-slip surface, at least 30m long, and an
appropriate width based on the number of participants.
Measuring tape of at least 20 meters.
Marker cones.
Audio cd or mp3.
Cd or mp3 player.
Loud speakers.
Recording sheets and pen
Drink Bottle: some athletes may wish to drink in their
recovery area during the yo-yo intermittent tests for
occasional small drinks to keep hydrated.
Course layout: Cones or tape is used to mark out three
parallel lines, 5 and 20 meters apart, as shown in the diagram.
Preparations: Make sure the participants are adequately
prepared: well-rested, hydrated and fueled, and familiar with
the test procedure and motivated to perform maximally. Give
clear and standardized instructions about the test and what is
expected of them including the importance of keeping in time
to the recording and completing the full 20m run.
Starting the Test: All participants should line up along the
starting line. The athletes start with a foot behind the middle
line (cone B), and begin running when instructed by the audio
recording. The athlete turns when signaled by the recorded
audio beep (at cone C), and returns to the starting point. The
athlete must not start running early, must run the complete
distance, and reach each line before or in time with the
recording.
During the test: There is an active recovery period of 10
seconds between every 40 meters run, during which the
subject must walk or jog to the next line (cone A) and return
to the starting point. At regular intervals, the running speed
will increase. The starting speed for the Level 1 Intermittent
Recovery Test is 10.0km/hr, and increases to 12km/hr,
13km/hr, then increasing by 0.5 km/hr thereafter.
Finishing the test: The participants must continue for as long
as they can. Some of the athletes will choose to stop when
they have reached their physical limit. For others, you will
need to give a warning as they drop behind the required pace
or make one of the errors listed below. On the second
infraction you pull them out of the test.
You give a warning when the participant
Does not come to a complete stop before starting the next
40m run.
Starts the run before the audio signal.
Does not reach either line before the audio signal.
Turns at the 20m mark without touching or going over
the line (therefore running short).
Scoring: The shuttle at which the second warning occurs is
not counted, e.g. if the second warning occurs at level 16.4,
the athlete's score is 16.3. When an athlete voluntarily
withdraws before a second warning, the last shuttle completed
successfully is their score. There are scoring sheets for each
test version to keep track of athlete scores during the test.
Interpretation: You can use the YYIR1 table of norms to
work out a fitness rating based on the score. There has been
formula published for estimating VO2max (ml/min/kg) from
the Yo-Yo IR1 results.
Outcome Measure
Total distance is much simpler to understand, calculate and
widely used, whereas level achieved is more complex as the
test begins at level 5 and then skips to level 9 at the
beginning.
Total Distance
This is the simplest, most common, and perhaps the most
reliable method of reporting YYIR test performance. To
calculate total distance, the simplest method is to record the
number of shuttles completed by the participant and then
multiply that number by 40 (40 = 2 x 20m shuttles [the run
~ 133 ~
International Journal of Physical Education, Sports and Health https://www.kheljournal.com
from cone B to cone C = 20m, then run back from cone C to
cone B = 20m]). For example, if an athlete performs 30
shuttles, this number can then be multiplied by 40 to calculate
their total distance (e.g., 30 x 40 = 1,200m)
Level Achieved
To calculate the levels which are achieved by the player is
according to the speed is one of the ways to evaluate the test
result. Below are the levels, speeds and accumulated distances
for the Yo-Yo Intermittent Recovery Test 1. The results can
be given as the total distance covered, level number achieved,
or speed level (such as 16.3, which would mean level 30 or
1200 meters). The results normally report the speed level plus
number of shuttles.
Table 1: Yo-Yo Intermittent recovery test-level 1
* Cumulative time includes 10 second recovery period between
shuttles
V02 Max
Though the YYIR1 has been shown to be a moderately
reliable predictor of V02 max [2, 10], it is advised to use the test
for what it was originally developed for identifying an
individual’s ability to repeatedly perform high-intensity
aerobic work, which has proven to be a more sensitive
measure of changes in performance than V02 max.
Regardless, for those who wish to use this method, the
equations for calculating V02 max are below:
YYIR1 test: V02 max (mL * kg-1 * min-1) = IR1 distance (m) ×
0.0084 + 36.4
Validity and Reliability
It is critical that the coach understands the test is both valid
and reliable before they include it within their testing battery.
Any test that lacks significant validity and/or reliability will
produce worthless results that should not be used literally.
Moreover, even a test with sufficient validity and reliability
will still have some degree of error/inconsistency, but
understanding how much is a crucial part of the data analysis.
The YYIR1 has been repeatedly proven as a valid and reliable
tool with high-reproducibility for measuring high-intensity
aerobic capacity amongst athletes from various sports and
competition-levels [3, 11-13]. Furthermore, the YYIR1 has also
been shown to be a moderately reliable predictor of maximal
oxygen uptake (VO2 max) [2, 10].

The data obtained were analyzed with IBM SPSS v26 ®
statistical software. The data showed normal distribution. The
Kolmogorov-Smirnov test and Shapiro-Wilk Test showed
significant difference in p<0.05.
Mean and standard deviation were calculated in order to study
the physical fitness components of the female batters and
bowlers. The mean was computed for comparison of players
of two groups. The “t-test'' was used to determine the
significant difference in performance, i.e., total distance
covered, levels reached, and VO2 max, between batters and
bowlers.

The above findings indicate that significant differences in
total distance covered were discovered between Batters and
Bowler, as the obtained t-value was greater than the tabulated
value of 2.00. The results also revealed that Bowlers have
performed better in total distance covered as well as in
VO2max as compared to the Batters. The results might be
attributed to their playing category, which includes different
types of practices. Additionally it was found that there was
significant difference in Level Achieved between the Batters
and Bowlers. The results of the present scenario point out the
positive quality of Bowlers as compared with Batters.
Conclusion
This study also found that there were significant
differences between batters and bowlers in total covered
distance, VO2Max and Levels achieved of YYIRT
Level-1
It was concluded that Bowlers had scored better in Level
Achieved as compared to the Batters
The results also revealed that Bowlers had performed
better in total distance covered as well as in VO2max as
compared to the Batters.

The present study aimed to investigate the changes in the physical profile of the England women's cricket team over a 13-year period. Physical profiles of 45 female players were retrospectively analysed from 2010 to 2022. Mixed linear modelling was employed to examine changes in various physical parameters including 10 m and 20 m sprints, countermovement jump (CMJ) height, aerobic fitness (measured through the Yo-Yo intermittent recovery test level 1, Yo-Yo-IR1), and push and pull strength endurance across time. There was a significant increase in Yo-Yo IR1 performance over time (P < 0.001), with the distance covered improving from 1077 metres in 2011 to 1666 metres in 2014. Both 10 m (P < 0.001) and 20 m (P < 0.001) sprint times significantly improved up to 2014. Furthermore, there were significant increases in push (P < 0.001) and pull (P < 0.001) strength endurance across time. However, no significant changes were observed in run-2 performance. Although there were significant changes (P < 0.001) in CMJ height across time, no clear trends were evident for year-to-year changes. Overall, the study demonstrated a significant physical evolution of the England Women's Cricket Team over 13 years, characterised by high aerobic fitness and upper body strength endurance. Future physical development should therefore focus on developing speed and change of direction qualities.

Background: Although Yo-Yo intermittent tests are frequently used in a variety of sports and research studies to determine physical fitness, no structured reference exists for comparison and rating of test results. This systematic review of the most common Yo-Yo tests aimed to provide reference values for test results by statistical aggregation of published data. Methods: A systematic literature search for articles published until August 2017 was performed in MEDLINE, Web of Science, SPORTDiscus and Google Scholar. Original reports on healthy females and males ≥16 years were eligible for the analysis. Sub-maximal test versions and the Yo-Yo Intermittent Recovery Level 1 Children's test (YYIR1C) were not included. Results: 248 studies with 9,440 participants were included in the structured analysis. 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. For each separate test, reference values (global means and percentiles) for sports at different levels and both genders were calculated. Conclusions: 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.

Abstract The present study investigated the test-retest reliability from the Yo-Yo IR1 (distance and heart rate responses), and the ability of the Yo-Yo IR1 to differentiate between elite and non-elite youth soccer players. A total of 228 youth soccer players (11-17 years) participated: 78 non-elite players to examine the test-retest reliability within 1 week, added with 150 elite players to investigate the construct validity. The main finding was that the distance covered was adequately reproducible in the youngest age groups (U13 and U15) and highly reproducible in the oldest age group (U17). Also, the physiological responses were highly reproducible in all age groups. Moreover, the Yo-Yo IR1 test had a high-discriminative ability to distinguish between elite and non-elite young soccer players. Furthermore, age-related standards for the Yo-Yo IR1 established for elite and non-elite groups in this study may be used for comparison of other young soccer players.

This study compares the performances obtained during soccer-specific field tests of the 20 m multistage shuttle run test (MST) and the Yo-Yo intermittent endurance test (YIET), with the measured maximal oxygen uptake (VO 2max) obtained in both field tests as well as that obtained in the traditional test of running to exhaustion on a treadmill (TRT), in young trained soccer players. Twenty-one National-level youth players performed, in random order, the MST and YIET to determine the relationship between the two field tests. From these, eight randomly chosen players performed their field tests as well as a TRT, equipped with an ambulatory gas exchange measurement device. Pearson correlation coefficient analysis showed that the players' performance (i.e. distance covered) in the MST and YIET was correlated (r = 0.65, p < 0.01). Players' performance in the YIET was not significantly correlated with the measured VO2max obtained in the same YIET nor with the measured VO 2max obtained in the MST and in the TRT (all p > 0.05). In contrast, significant correlations were observed between the players' performance in the MST with the measured VO 2max obtained in the same MST and in the YIET (both p < 0.05); and attained almost statistical significance with the measured VO 2max in the TRT (p = 0.06). The lack of association between distances covered in the YIET with all the measured VO 2max values suggest that measured VO 2max per se may not be suitable to characterize soccer players' intermittent endurance performance. In comparison with the MST, the YIET may be a more favourable field-based assessment of soccer player's endurance performance.

The purposes of this study were to determine the relationship between performance in the Yo-Yo intermittent recovery test level 1 (YIRT1), the Yo-Yo intermittent recovery test level 2 (YIRT2) and the Yo-Yo endurance test (continuous) (YET) with maximal oxygen uptake (VO2max) and Wingate anaerobic performance (WaNT) test results in young soccer players (age 15.00 ± 0.0 years, body height 176.3 ± 4.2 cm and body mass 68.1 ± 3.6 kg). An ergospirometry device was used during the treadmill test (TRT) to determine VO2max. At the end of the study, significant differences were found between the Yo-Yo tests and TRT in terms of HRmax (TRT = 195,92, YIRT1 = 197,83, YIRT2 = 198,5 YET = 198) (p > 0.05). While there were moderate correlations between VO2max and YIRT 1-2 performances (respectively, r = 0.56, r = 0.53), there was only a weak relationship between VO2max and YET performance (r = 0.43) (distance covered). There were also moderate significant negative correlations between performance in the YIRT2 and peak power measured in the WaNT (r = -0.55), although there were no significant correlations between performance in the three tests and average power. A moderate negative correlation was found between performance in the YIRT2 and Fatigue index (FI) (r = -0,66). In conclusion, the YIRT2 may be a more suitable field test for determining both aerobic and anaerobic performance in soccer players.

The aim of this study was to examine the possible association between Yo-Yo intermittent recovery test level 1 performance (distance covered, Yo-Yo IR1) and match activities (direct validity) in young male team handball players. Eighteen young male players (age 14.3 +/- 0.5 years, body mass 64 +/- 28.7 kg, height 174 +/- 6 cm, body fat 11.2 +/- 3.9%) took part in this study. Players' match activities were videotaped during an experimental tournament (6 games/player) and analyzed using a computerized system. Games and Yo-Yo IR1 heart rates (HRs) (short-range telemetry, HR) and blood lactate concentrations ([la]b) were assessed throughout and at selected times of the games, respectively. Peak Yo-Yo IR1 HR was assumed as representative of individual maximal HR (HRmax). Mean and peak game HRs were 174 +/- 3 and 198 +/- 2 b.min, which corresponded to 87 and 99% of HRmax, respectively. Yo-Yo IR1 performance (1,831 +/- 373 m) was significantly related (r = 0.88, p < 0.01) to total game distance (1,921 +/- 325 m). Post-game (9.2 +/- 2.3 mmol.L) and Yo-Yo IR1 (8.8 +/- 1.6 mmol.L) [la]b were significantly related (r = 0.51, p < 0.05). These findings demonstrated the direct validity of Yo-Yo IR1. Consequently, Yo-Yo IR1 test may be considered as a team handball test relevant for the assessment of intermittent high-intensity endurance in young male team handball players.

The two Yo-Yo intermittent recovery (IR) tests evaluate an individual’s ability to repeatedly perform intense exercise. The Yo-Yo IR level 1 (Yo-Yo IR1) test focuses on the capacity to carry out intermittent exercise leading to a maximal activation of the aerobic system, whereas Yo-Yo IR level 2 (Yo-Yo IR2) determines an individual’s ability to recover from repeated exercise with a high contribution from the anaerobic system. Evaluations of elite athletes in various sports involving intermittent exercise showed that the higher the level of competition the better an athlete performs in the Yo-Yo IR tests. Performance in the Yo- Yo IR tests for young athletes increases with rising age. The Yo-Yo IR tests have shown to be a more sensitive measure of changes in performance than maximum oxygen uptake. 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.

The aim of the present study was to a) examine the relationship between performance of the Yo-Yo Intermittent Recovery Test Level 1 (Yo-YoIR1) and the 30-15 Intermittent Fitness Test (30-15IFT) and b) compare the sensitivity of both tests to training. Fourteen young soccer players performed both tests before and after an eight-week training intervention, which included six sessions/week: two resistance training sessions, two high-intensity interval training sessions after technical training (four sets of 3:30 min of generic running and small sided games (4v4) during the first and second four-week periods, respectively, [90-95% maximal HR], interspersed with 3 min at 60-70% maximal HR) and two tactical-only training sessions. There was a large correlation between 30-15IFT and Yo-YoIR1 (r = 0.75, 90% confidence limits, CL 0.57;0.86). While within-test % changes suggested a greater sensitivity to training for the Yo-YoIR1 (+35%, 90%CL 24;45) compared with the 30-15IFT (+7%; 4;10), these changes were similarly rated as 'almost certain' (with chances for greater/similar/lower values after training of 100/0/0 for both tests) and moderate, i.e., standardized difference, ES = +1.2 90%CL (0.9;1.5) for Yo-YoIR1 and ES = +1.1 (0.7;1.5) for 30-15IFT. The difference in the change between both tests was clearly trivial (0/100/0, ES = -0.1, 90%CL -0.1;-0.1). Both tests might evaluate slightly different physical capacities, but their sensitivity to training is almost certainly similar. These results also highlight the importance of using standardized differences instead of % changes in performance to assess the actual training effect of an intervention.

The purpose of the study was to determine the reliability of yo-yo intermittent recovery test (yo-yo) scores and their degree of association with a 20-m shuttle run (20MSR) and VO(2max) values. Subjects were elite (Australian Football League [AFL], n = 23), state-level (hockey, n = 15, and cricket, n = 27), and recreational team-sport players (n = 33). All performed a 20MSR and the yo-yo at either level 1 (recreational and state level) or level 2 (AFL). A recreational subgroup (n = 19) also performed a treadmill VO(2max) test. Test-retest results found the yo-yo (levels 1 and 2) to be reliable (ICC = .86 to .95). The 20MSR and yo-yo level 1 scores correlated (P < .01) in the recreational (r = .81 to .83) and state-level groups (r = .84 to .86), and 20MSR and yo-yo level 2 scores, in the elite (r = .86) and recreational groups (r = .55 to .57). The VO(2max) and yo-yo level 1 scores in the recreational group correlated (P < .01, r = .87), but no association was found with yo-yo level 2 (r = .40 to .43, nonsignificant). We conclude that level 1 (recreational and state level) and level 2 (elite) yo-yo scores were both strongly associated with 20MSR scores and VO(2max) (level 1: recreational subjects only). The yo-yo appears to measure aerobic fitness similarly to the 20MSR but may also be used as a field test of the ability to repeat high-intensity efforts.

To examine the physiological response and reproducibility of the Yo-Yo intermittent recovery test and its application to elite soccer. Heart rate was measured, and metabolites were determined in blood and muscle biopsies obtained before, during, and after the Yo-Yo test in 17 males. Physiological measurements were also performed during a Yo-Yo retest and an exhaustive incremental treadmill test (ITT). Additionally, 37 male elite soccer players performed two to four seasonal tests, and the results were related to physical performance in matches. The test-retest CV for the Yo-Yo test was 4.9%. Peak heart rate was similar in ITT and Yo-Yo test (189 +/- 2 vs 187 +/- 2 bpm), whereas peak blood lactate was higher (P < 0.05) in the Yo-Yo test. During the Yo-Yo test, muscle lactate increased eightfold (P < 0.05) and muscle creatine phosphate (CP) and glycogen decreased (P < 0.05) by 51% and 23%, respectively. No significant differences were observed in muscle CP, lactate, pH, or glycogen between 90 and 100% of exhaustion time. During the precompetition period, elite soccer players improved (P < 0.05) Yo-Yo test performance and maximum oxygen uptake ([OV0312]O(2max)) by 25 +/- 6 and 7 +/- 1%, respectively. High-intensity running covered by the players during games was correlated to Yo-Yo test performance (r = 0.71, P < 0.05) but not to [OV0312]O(2max) and ITT performance. The test had a high reproducibility and sensitivity, allowing for detailed analysis of the physical capacity of athletes in intermittent sports. Specifically, the Yo-Yo intermittent recovery test was a valid measure of fitness performance in soccer. During the test, the aerobic loading approached maximal values, and the anaerobic energy system was highly taxed. Additionally, the study suggests that fatigue during intense intermittent short-term exercise was unrelated to muscle CP, lactate, pH, and glycogen.

The aim of this study was to examine yo-yo intermittent recovery test (Yo-Yo test) and 12-minute run test (12MRT) performances in experienced soccer referees of different competitive levels. Three groups (n = 14 each) of experienced Italian soccer referees officiating in the first (series AB, top-level), third (series C, medium-level), and fourth (series D, low-level) division, were randomly submitted to the 12MRT and the Yo-Yo test during 2 testing sessions, 48-hours apart. 12MRT performances were 3,000 +/- 112 m; 2,894 +/- 99 m; and 2,896 +/- 171 m for top-level, medium-level and low-level referees, respectively (p > 0.05). In the Yo-Yo test, the top-level, medium-level, and low-level referees covered 1,874 +/- 431 m; 1,360 +/- 172 m; and 1,272 +/- 215 m, respectively. The test performances of top-level referees in the Yo-Yo test was significantly different from those scored by medium-level and low-level referees (p < 0.05). After the Yo-Yo test, blood lactate concentrations (BLC) were higher in the medium-level and low-level referees compared with the top-level referees (p < 0.05). The results of the present study show that the Yo-Yo test and not the 12MRT can discriminate endurance performance in experienced elite level soccer referees. With respect to its discriminative and match performance validity, the Yo-Yo test may be considered a relevant field test to assess endurance preparedness for experienced soccer referees and a useful tool in talent selection.
