摘要This study determined the relative human working intensity of children walking with different loads. Fifteen male children, aged 12, were selected from a primary school to carry school bags of 1http://aims.cuhk.edu.hk/converis/portal/Publication/0, 15 and 2http://aims.cuhk.edu.hk/converis/portal/Publication/0% of their body weights, and no load was used as control. Maximal oxygen uptake (VO(2)max) of every subject were measured on a motorized treadmill using a continuous incremental protocol. In the load carriage test, subjects walked a 1.1 m s(-1) for 2http://aims.cuhk.edu.hk/converis/portal/Publication/0 min on a treadmill. During walking, expired gas of subjects were collected and analyzed by a cardiopulmonary function system. Based on the results of expired gas analysis, human walking intensity during walking at different load conditions were calculated and presented by the percent of VO(2)max. Heart rate of subjects were monitored and recorded by electrocardiograph until five min after walking. Blood pressure were measured before, immediately, 3 and 5 min after every trial. There was a significant difference found on the human working intensity between 1http://aims.cuhk.edu.hk/converis/portal/Publication/0 and 2http://aims.cuhk.edu.hk/converis/portal/Publication/0% body weight load conditions, but not among the http://aims.cuhk.edu.hk/converis/portal/Publication/0%, 1http://aims.cuhk.edu.hk/converis/portal/Publication/0% and 15% body weight load conditions. Heart rate responses among all Load conditions showed similar trends. 6http://aims.cuhk.edu.hk/converis/portal/Publication/0% maximum heart rate was obtained at different Load conditions among the subjects. It is concluded that 1http://aims.cuhk.edu.hk/converis/portal/Publication/0% body weight is recommended as the weight of school bags for children.
