avje otrok in mladostnikov | health of children and adolescents 138 In the Normal_weight group (Table 2) was detected a low degree of cor-
relation between explosive power and muscle and fat mass (r <0.29). In the
Overweight group was detected a high degree of correlation between explo-
sive strength and muscle and fat mass (r > 0.50), except for fat mass percent-
age, there is a low negative correlation (r = -0.102). In the Obesity group was
detected a low degree of correlation between explosive power and muscle and
fat mass (r <0.29). In all BMI groups, the correlation of explosive strength with
muscle and fat mass is not statistically significant (p >0.05).
Discussion
The findings of our research are consistent with the findings of the research
conducted by Matarma et al. (2018). Healthy-weight children had higher scores
in strength and agility compared to overweight or obese children. Moreover, in
a study by Reeves et al. (1999) higher body fat as measured by skinfolds in pre-
school children was associated with worse half-mile running time. Also, Hen-
riksson et al. (2016) in their research found that in four-year-old children, body
fat percentage was associated with a worse performance in the 20 m shuttle
run, standing long jump and 4 x 10 m shuttle run tests.
Carnevale Pellino et al. (2020) investigated the difference between the
sexes and reported that boys did not significantly increase their performance
while growing up, while girls did improve their performance. Sadri et al. (2014)
also found the same. In our study, possibly due to the small sample size, we did
not detect gender differences.
Conclusions
Reducing the proportion of fat mass in the body and increasing the proportion
of muscle mass in the preschool period is important for well-developed explo-
sive power. Improvements in lower body muscle strength over the 12-month
follow-up period are associated with decreases in body fat mass index and body
fat percentage (Henriksson et al., 2019).
For the development of explosive power and consequently for good physi-
cal health it is necessary to offer children enough physical and sports activities,
which include jumping and running, already in the pre-school period.
