"11 for Health" in China - Effects on physical fitness in 9-11-year-old schoolchildren.

ABSTRACT Previous studies have shown that the school-based physical activity programme entitled "11 for Health" has been effective in improving the physical fitness, well-being and overall health profile of European children. The main purpose of the present study was to examine whether the "11 for Health" programme can have a positive impact on the physical fitness of primary school pupils in China. A total of 124 primary school pupils aged 9-11 years were included in the experiment, randomly divided into the experimental group (EG, n  = 62) and the control group (CG, n  = 62). EG carried out three weekly 35-minute sessions of small-sided football for a total of 11 weeks. All data were analysed by a mixed ANOVA with the Student-Newman-Keuls post hoc test. The results showed greater improvements ( p <0.001) in EG than CG in relation to systolic blood pressure (-2.9 vs +2.0 mmHg). Moreover, greater improvements (all p <0.05) were observed in postural balance (13 vs 0%), standing long jump (5.0 vs 0.5%), 30-metre sprint (4.1 vs 1.3%) and Yo-Yo IR1C running performance (17% vs 6%). In both EG and CG, physical activity enjoyment was observed to be higher ( P <0.05) compared to the start of the intervention with increases of 3.7 and 3.9 AU respectively. In conclusion, the study revealed that the "11 for Health" programme has positive effects on aerobic and muscular fitness, and it appears to be a relevant tool in the physical activity promotion in the Chinese school system.
