Physical exercise can enhance various aspects of character and education, but children may not engage due to a variety of barriers. Circus Skills Training (CST) is a novel approach to encourage participation in exercise and develop physical literacy. It delivers circus skills in a positive, non-competitive and supportive social atmosphere, making it particularly appealing to those who avoid traditional competitive team sports. In a between-subjects design we compared 2 groups of children (aged 9–12) on various measures of physical and psychological wellbeing at baseline, and again after one group had received 6 months of CST training as part of their school’s physical education classes. Significant differences between CST and none-CST children were found for teacher ratings of emotional problems, with the CST-group showing fewer such problems. CST could offer an innovative means of encouraging children to engage with exercise and provide wider benefits in terms of psychological wellbeing.
