The Yo-Yo Intermittent Tests are
similar to the Yo-Yo Endurance Test (a variation of the beep test), except in the
intermittent tests the participants have a short active break (5 and 10 seconds
for the endurance and recovery test, respectively). There are two versions of
the Yo-Yo Intermittent Test: the Level or Stage 1 test starts at 10 km/hr and
the Level or Stage 2 test starts at 13 km/hr. These tests were developed by
famous Danish soccer physiologist Jens Bangsbo.
purpose: The test evaluates an
individual's ability to repeatedly perform intervals over a prolonged period of
time, particularly for athletes from sports such as tennis, team handball,
basketball and soccer.
diagram:
equipment required: Flat,
non-slip surface, marking cones, measuring tape, pre-recorded audio
cassette or cd, cd or cassette player, recording sheets.
description: Use cones to
mark out three lines as per the diagram above; 20 meters and 5 meters apart.
The subject starts on or behind the middle line, and begins running 20 m when
instructed by the cd. This subject turns and returns to the starting point when
signaled by the recorded beep. There is a active recovery period (5 and 10 seconds
respectively for the endurance and recovery versions of the test) interjected
between every 20 meter (out and back) shuttle, during which the subject must
walk or jog around the other cone and return to the starting point. A warning
is given when the subject does not complete a successful out and back shuttle
in the allocated time, the subject is removed the next time they do not
complete a successful shuttle.
