A sample of 57 subjects consisting of selected junior female players, aged 13 or
14, was used to measure maximal isometric muscle strength for certain muscle groups,
more specifically, for hand flexors (dominant and non-dominant), back extensors and
leg extensors. The main morphological parameters of the 14-year old subjects were
the following: BH±SD = 1.719±0.065 meter; BM±SD = 64.36±6.36 kilogram;
BMI±SD = 21.78±1.93 (kg/m2), and for the 13-year olds they were: BH±SD =
1.667±0.056 meter; BM±SD = 58.71±9.87 kilogram; BMI±SD = 21.01±2.58 (kg/m2).
Based on the obtained descriptive statistics results, a conclusion can be drawn that the
mean value for the variable of the dominant hand grip amounted to 33.87±4.92 daN
with the 14-year old subjects and 28.58±5.98 daN with the 13-year old ones, whereas
the mean values for the non-dominant hand grip were 30.94±4.24 daN and 25.36±5.50
daN, respectively. The values for the variable of back extensors force showed mean
values of 87.28±13.41 daN; 77.22±12.19 daN, respectively, whereas the mean values
for leg extensors were 86.19±12.65 daN; 76.01±18.19 daN, respectively. Based on the
results of Students' test, it can be concluded that the results obtained for the variables
that measured the maximum isometric force of the flexors of the dominant hand, nondominant
hand, back extensors, and leg extensors, there is a statistically significant
difference at 95% probability level, because t = 13.095, p = 0.001; t = 18.065, p =
0.000; t = 8.798, p = 0.004; t = 5.891, p = 0.019, respectively. handball, selection, maximum force, isometrics
