Childhood obesity is one of the most critical and accelerating health challenges throughout the world. It is a major risk factor for developing varus/valgus misalignments of the knee joint. The combination of misalignment at the knee and excess body mass may result in increased joint stress and damage to articular cartilage. A training programme, which aims at developing a more neutral alignment of the trunk and lower limbs during movement tasks may be able to reduce knee loading during locomotion. Despite the large number of guidelines for muscle strength training and neuromuscular exercises that exists, most are not specifically designed to target the obese children and adolescent demographic.
The purpose of this study is to evaluate a training programme which combines strength and neuromuscular exercises specifically designed to the needs and limitations of obese children and adolescents and analyse the effects of the training programme from a biomechanical and clinical point of view.

The Austria-German version of the Knee Injury and Osteoarthritis Outcome Score will be used to assess the participants' opinion about their knee. |
| Baseline and 12 weeks |
| Gait pattern | Kinematics and external joint moments for the sagittal and frontal plane for hip, knee and ankle joints as well as spatio-temporal parameters will be assessed by 3D gait analysis during walking and stair climbing. | Baseline and 12 weeks |
| Adherence to the training programme | Adherence will be considered as the percentage of actually completed sessions during the intervention period among the number of intended exercise sessions. | Participants will be followed for the duration of the intervention (12 weeks) |
| Ratings of knee related pain | Ratings of knee related pain will be assessed using a 7-point ordinal scale. | Participants will be followed for the duration of the intervention (12 weeks) |
The anthropometric evaluation will include the measurement of height, weight, waist circumference, hip circumference, waist-to-hip ratio and calculation of the body mass index.
| Baseline and 12 weeks |
| Body Composition | Body composition parameters will include, fat mass, fat free mass, total body water, body cell mass, extracellular mass and lean body mass. | Baseline and 12 weeks |
| Nutritional status | The nutritional status will be assessed using the 24-hour recall method. This method records the daily, self-reported consumption of food-intake. In combination with a standardized nutritional food programme (EBISpro) the intake of macro- and micronutrients will be estimated. | Baseline and 12 weeks |
| Psychological status | The AD-EVA test inventory as well as the Child Behavior Checklist (CBCL/4 -18 ) will be used to determine the psychological status of the participants. | Baseline and 12 weeks |
| Blood samples | Quantification of routine blood sampling in obese patients and growth hormones and inflammation will be performed from venous blood samples in the Laboratory of the Department of Pediatrics and Adolescent Medicine at the Medical University of Vienna. | Baseline and 12 weeks |
