ANOVA test indicated no significant sex main effect on flexibility test scores (F(1, 2007)=0.027; P>0.05), whereas this yielded a substantial age main effect (F(3, 2007)=3.407; P<0.05). On average, boys had a slight, but significantly superior push-up performance (9.1±3.9) compared to girls (8.6±3.5) (P=0.04; P<0.05). Results also indicated substantial age difference in push-up scores among boys and girls (F(1, 3)=11.1; P<0.05). There were no significant age/ sex interaction effect (F(3, 2007)=1.396; P>0.05) and sex main effect in the sit-up performances for the boys and girls (P=0.188; P>0.05). Boys had significantly (P<0.05) higher mean sit-up values, at ages 10 and 12, whereas no statistically significant sex main effect was found regarding the children’s sit-up scores (F(1, 2007)=1.134; P>0.05). Conclusion. Whereas the study showed non-significant sex and age differences in flexibility between boys and girls, marked age- and gender- related discrepancies were found regarding muscular strength. The muscular endurance component showed inconsistent results across age groups.]]> Tue 03 Apr 2018 12:43:00 SAST ]]>
