Children and adolescents with inflammatory bowel disease (IBD) suffer from many extra-intestinal side effects, including impaired muscle strength, low aerobic fitness, low bone density, and chronic inflammation. While exercise training can help remedy these issues in adults with IBD, no studies have examined the physiological effects of a structured aerobic and resistance exercise training intervention for youth with IBD.
The aim of this pilot study is to to assess the feasibility, safety, and participant satisfaction of a structured 16-week training program for children with IBD. The secondary objectives of this study were to quantify the effects of a 16-week exercise training program on select physiological and behavioural outcomes in children with IBD.

Assessed by qualitative interview looking at likes and dislikes of the training program as well as suggestions for improvement
| Change from baseline at 8 weeks and 1 week post intervention |
| Tracking adverse events | Adverse events are event that occurs during the course of exercise training that cause the participant physical or psychological harm | During training session |

| Change from baseline at 8 weeks and 1 week post intervention |
| Bone mineral density | Bone mineral density (g/cm^3) measured by Dual X-ray Absorptiometry scan. | Change from baseline at 8 weeks and 1 week post intervention |
| Aerobic fitness: maximum rate of oxygen consumption attainable during physical exertion | VO2 peak (L*min-1) measured by the McMaster All-Out Progressive Continuous Cycling Test using a calibrated metabolic cart | Change from baseline at 8 weeks and 1 week post intervention |
| Aerobic fitness: peak workload | peak workload (watts) measured by the McMaster All-Out Progressive Continuous Cycling Test using a cycle ergometer | Change from baseline at 8 weeks and 1 week post intervention |
| Aerobic fitness: peak heart rate | Peak heart rate (beats*min-1), measured by the McMaster All-Out Progressive Continuous Cycling Test using heart rate monitor | Change from baseline at 8 weeks and 1 week post intervention |
| Muscle strength | Grip strength (Nm), isokinetic and isometric leg strength (Nm) and isokinetic and isometric arm strength (Nm) all measured with an isokinetic dynamometer | Change from baseline at 8 weeks and 1 week post intervention |
| Physical activity levels | Time spent in physical activity (at light, moderate and high intensity) and sedentary time (min*day-1) measured by a waist-worn accelerometer | Change from baseline at 8 weeks and 1 week post intervention |
| Inflammatory cytokine levels | IL-6 and TNF-alpha concentrations (pg/ml) measured from patient plasma by enzyme-linked immunosorbent assays | Change from baseline at 8 weeks and 1 week post intervention |
