Sažetak
The goal of this study was to determine differences of
some anthropometric characteristics and motor abilities in
boys aged between 14 and 15 during a period of 6 months.
Data obtained through this study shall provide a response
as to whether the observed chronological age is adequate
for intensifying water and dry land training. For that
purpose, 39 swimmers belonging to Zagreb swim clubs,
aged between 14 and 15, were measured using a battery of
23 anthropometric dimensions, including bone length,
bone width, body volume and mass, as well as
subcutaneous adipose tissue. In order to assess motor
abilities, 10 tests were taken. Descriptive statistical
indicators have shown an extremely high variability of all
measured characteristics and abilities, some of which
have demonstrated irregular distribution of results.
Student s T-test for dependant samples determined that all
measures of bone length, bone width and body volume
and mass are showing statistically significant differences
with regard to increase in values. Measures of
subcutaneous adipose tissue are decreasing with statistical
significance when extremities are concerned, while skin
folds on the trunk are not showing any statistically
significant difference. In the analysis of variations
between motor test results, back extensions, squats during
60 seconds and twists with the stick have not shown
statistical significance, while others have shown
statistically significant differences between the first and
second measuring (p 0,05).
Canonical analysis of the first and second measuring
indicates that within each measuring there is one
statistically significant pair of factors between these two
sets of variables (p 0.05). However, the structure of
individual factors shows that significant changes had set
in with regard to the relationship of the two observed sets
of variables.
