Abstract: 

Students commonly use backpacks to carry their textbooks, books, pencils, etc on a daily basis. The purpose of this study was to determine the effects of different backpack weights on pulmonary capacities of schoolchildren. This study was conducted among 30 boy and girls primary school students. Each partticipants for 20 min with different backpack weights (0, 5, 10 and 15% of body weight) in different days on a treadmill at a speed of 1/1 meters per second would carry. Their lung capacity is vital capacity, forced expiratory volume of air in one second and the ratio of these two measurements were recorded using a spirometer. According the results, significant relationship between the weight of the backpack there was with forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1) and FEV1/ FVC ratio. The FVC levels were higher in boys than girls and differences between the two groups showed significant. FEV1 levels were higher in girls than boys and differences between the two groups showed significant relationship. In general, backpack weight with each elementary school students was led to reduced lung capacity, carrying backpacks heavier obviously more serious consequences will follow. Therefore appropriate strategies should be carried out on a backpack to remove the Iranian elementary school students.
