a strong trendP=0.06
There was also a strong trend towards an increase in CRF amongst the SIT group (P=0.06) coupled with large effect size (ES =0.93) in the present study, suggesting that a longer intervention, or a higher intensity may have produced significant improvements as demonstrated by similar SIT investigations [ 12 , 18 , 34 ], each of whom report significant improvement in CRF following 12 weeks of SIT in obese adolescents.
