This study was undertaken as a prelimimary investigation to compare cycling errors and sudden stopping distance in secondary students traversing an obstacle course on their bicycle with and without a schoolbag, to determine if further studies of cycling accident aetiology amongst children were warranted. Twenty children cycled as fast as they could around an obstacle course. Each child undertook two separate trials, about an hour apart on a morning of the same day. The children traversed the course one at a time in turn using their own bicycle and wearing their own usual school clothes. For the first trial they did not carry a schoolbag. On the second trial they carried a schoolbag weighing 6 kg. There were no significant differences in the number of cycling errors made by the children when traversing the obstacle course with and without a schoolbag. However, the children generally took longer to complete the course when carrying the schoolbag and stopping distances were greater. It was not possible to be certain that these findings were genuine or whether the effect of carrying the choolbag was reduced by increased familiarity with the course, smce all of the children first traversed the course without a schoolbag and then with one. It is concluded that there is some justification for conducting further studies to explore the implications of carrying schoolbags on cycling accident aetiology amongst children. (Author/publisher)
