<b>Correlation of Outdoor Games and Lung Function of School Going Children</b> Outdoor games and playful workout routines can be the tools that instill not only lasting joy of exercise but also wellbeing of the children. The present research aims to investigate the relationship between outdoor games and lung function of school going children. A cross sectional school based study was carried out among 1926 school going children 10 14years including both girls and boys from each of the 4 regions of the Union Territory of Puducherry by stratified random sampling method. Through interview schedule information regarding socio demographic background, health status and lifestyle pattern were elicited. Nutritional status was determined using anthropometric measurements height, weight and chest circumference and body mass index. Peak flow meter and pulse oximeter were used to analyze the peak expiratory flow rate PEFR , oxygen saturation and pulse rate. Data was analyzed using SPSS version 18.0. Outdoor games had a significant correlation with BMI p=0.010 and PEFR value 0.000 . The mean difference in PEFR value between those engaged in outdoor games for 1 hour and 1 to 2 hours per day was found to be 13L min. The pulse rate was found to be higher among those who spent 1 hour. Therefore, this study concludes that outdoor games have a positive effect on the lung function of children.
