[Aerobic capacity and quality of life in school children from 8 to 12].

Aerobic capacity is a powerful physiological indicator of the overall health status. The objective of this study was to analyse the relationship between aerobic capacity and quality of life in a sample of 298 (159 girls) school children aged 8-12 years. Aerobic capacity was tested using the Course-Navette test. Quality of life was assessed using the KIDSCREEN-10 Index scale. Males showed higher performance in the Course-Navette test and highest values of VO2max (P<.001 for both). ANOVA statistical analysis showed that the quality of life was significantly higher in school children with increased level of aerobic capacity compared to those with a low level (P=.001). Children with high aerobic capacity showed higher quality of life scores in relation to their peers with low scores (P<.001). As for the females, significant differences were found among those with high aerobic capacity level and their peers low levels (P<.031). The results of this study suggest that school children with higher level of aerobic capacity show better results in the quality of life index. Long-term intervention studies are needed to verify if an aerobic capacity development programme may upgrade the quality of life of children and adolescents.
