Table 3. Comparison of sleep quality and quality of life according to the performance level in girls.
Values expressed as mean (standard deviation) or percentage (%). For quantitative variables, the General Linear Model adjusted for age, BMI, municipality size, economic level was used. Post hoc pairwise comparisons were performed with Bonferroni: * p < 0.05 vs. inactive; + p < 0.05 vs. non-competitive; ^ p < 0.05 vs. local football; # p < 0.05 vs. regional football. For qualitative variables, differences were examined using the Chi-square test.
