From Shaun Austin:
The Yo-Yo test (specifically the Yo-Yo Intermittent Recovery Test) is a form of fitness testing used by elite athletes and coaches and has been found to be a highly effective approach to assessing a sports competitor's fitness levels. This specialised form of Bleep Test (Beep Test, Shuttle Run Test) is designed to simulate the intermittent nature of certain sporting activities such as Soccer/Football, Rugby, Hockey, Grid-iron, Basketball etc. It is in these sports where the pattern is that of short, rapid bursts of intense activity followed by less intense recovery periods. Because of the nature of the test and its proven reliability, it has been adopted by SPARQ as part of the assessment and training programme and features highly in soccer training schools.Now the Yo-Yo Intermittent Recovery Test, powered by the same engine as the highly popular Bleep Test Pro application is available for your own training on your iPhone or iPod Touch.* Full instructions* Records results in level/shuttle and distance covered.* Provides rating based on score and VO2Max for each test.* Keep a sortable history log of your tests to track fitness over time.* Publish your test results via Twitter to compare with your friends.For more information about the Yo-Yo Intermittent Recovery Test, visit our website using the link below.
