Abstract: High test retest reproducibility is essential in tests used for
monitoring athletic performance. The purpose of this study was to establish the
reproducibility (R) and validity (V) of Hacettepe Intermittent Jumping Test
(HIJT) applied in order to determine physiological and mechanical changes
during maximal intermittent jumping exercise (5*15 s maximal jumping and 60 s
passive recovery between series). Subjects were measured 3 times on separate
days to test the R and once in random order to test the V of the HIJT. Subjects
performed HIJT on a platform with their hands on their waist. During the study,
total and mean power outputs, fatigue index, rest and maximal heart rate were
calculated. Three different testing groups (n = 34) joined
the R study while only one of these groups joined the V study in which subjects
jumped for a minute (60CJT) with their maximum effort. During this stage blood
samples were taken from the earlobes of subjects, at the beginning and at the
end of the test. A significant correlation was found among tests of different
groups on different days (p < 0.05) and HIJT gave similar
results during different trials (p > 0.05). The relationships
between HIJT and 60CJT were significant (p < 0.05). Based on
correlational analysis HIJT demonstrated satisfactory R and V and may thus be
used both under laboratory and field conditions to evaluate anaerobic
fitness.
