Abstract
The aim of this study was to design a new field test
that measures dynamic stability of lumbar spine joints
(controlled range of motion). It was also a goal to
determine the metric characteristics of the newly designed
test on two groups of subjects differing on their physical
preparedness. The sample was composed of 35 girls aged
9-20 years from Zagreb, Croatia. Fifteen of them were
rhythmic gymnasts who at average trained 8.93 hours per
week, for at least 5 years. The other group consisted of 20
female pupils of the secondary school “Borovje” who
were not engaged in any regular sport activity beside
physical education classes. The subjects performed 2 tests
for the evaluation of lumbar spine dynamic stability. One
well known and with estabilished metric characteristics
(F-1), and the other one, newely constructed (F-2). The
normality of the distributions was examined using the
Kolmogorov–Smirnov test (KS). Validity and reliability
were estimated with the Factor analysis. The intraclass
correlation coefficient (ICC) was used for homogeneity
evaluation. for independent samples was used to
establish the capacity of the new test to discriminate the
lumbar spine dynamic stability of trainees and
nontrainees. The obtained results showed that the new test
has high sensitivity, validity, reliability and homogeneity,
tested on two groups of same age but different level of
physical preparedness. Such results stress the wide
applicability of the newly constructed test regardless on
the level of physical preparedness or the work conditions.
It is thus usable in sports as well as in physical therapy
practice.
