Childhood Obesity, Obesity
Conditions
Brief summary
Childhood obesity is an ongoing and increasing issue, resulting in changes in body mass which cause biomechanical alterations in the lower limbs. Exercise interventions have been effectiveness at causing positive changes to the lower limbs gait, strength and functioning but children often report lack of enjoyment from the sessions which inhibits long term changes. This intervention takes a neuromuscular exercise approach whilst considering the psychological needs of children to motivate them to participate in the intervention and physical activity.

Training program consisting of two neuromuscular training sessions per week

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in body fat percentage | From baseline to end of 8-week training program and to end of 8-week follow-up | Bioelectrical impedance analysis of fat mass relative to body mass |
| Change in fat free mass | From baseline to end of 8-week training program and to end of 8-week follow-up | Bioelectrical impedance analysis of fat free mass relative to body mass |
| Change in body mass index (BMI) | From baseline to end of 8-week training program and to end of 8-week follow-up | BMI calculated with height measured barefoot on weight scales and height measured barefoot on Stadiometer and Z-score based on standard measures for age and gender. A reduction in BMI is a positive change. |
| Change in Hip 3d gait analysis | From baseline to end of 8-week training program and to end of 8-week follow-up | 3D joint angle, moment and power waveforms during stance phase. Moment and power dimensionless and normalised to body mass and leg length. Time normalised to 100% of stance and walking at a self-selected pace. |
| Change in Knee 3d gait analysis | From baseline to end of 8-week training program and to end of 8-week follow-up | 3D joint angle, moment and power waveforms during stance phase. Moment and power dimensionless and normalised to body mass and leg length. Time normalised to 100% of stance and walking at a self-selected pace. |
| Change in Ankle 3d gait analysis | From baseline to end of 8-week training program and to end of 8-week follow-up | 3D joint angle, moment and power waveforms during stance phase. Moment and power dimensionless and normalised to body mass and leg length. Time normalised to 100% of stance and walking at a self-selected pace. |
| Change in Foot 3d gait analysis | From baseline to end of 8-week training program and to end of 8-week follow-up | Angle of the forefoot, midfoot, rearfoot and shank during the stance phase when walking at a self-selected pace. |
| Change in lower limb strength relative to body mass | From baseline to end of 8-week training program and to end of 8-week follow-up | Lower limb strength measured on Isokinetic Dynamometer in hip flexion/extension, hip abduction/adduction, knee flexion/extension, ankle plantarflexion/dorsiflexion. Maximal moments allometrically scaled to body mass |
| Change in lower limb strength relative to fat free mass | From baseline to end of 8-week training program and to end of 8-week follow-up | Lower limb strength measured on Isokinetic Dynamometer in hip flexion/extension, hip abduction/adduction, knee flexion/extension, ankle plantarflexion/dorsiflexion. Maximal moments allometrically scaled to fat free mass |
| Change in physical functioning: six-minute timed walk | From baseline to end of 8-week training program and to end of 8-week follow-up | Distance walked at a self-selected speed for six minutes |
| Change in physical functioning: sit-to-stand test | From baseline to end of 8-week training program and to end of 8-week follow-up | The amount of repetitions of moving from a sitting position with knees at 90 degrees flexion to an upright standing position and return in one minute. Arms fixed across chest. |
| Change in physical functioning: timed up and go test | From baseline to end of 8-week training program and to end of 8-week follow-up | Time taken to rise from a seated position with knees at 90 degrees flexion and arms across chest, walk 3m and return back to seated position |
| Change in physical functioning: single leg stand eyes open | From baseline to end of 8-week training program and to end of 8-week follow-up | Maximal time to maintain balance on one leg with hands on hip and free leg bent to 90degrees flexion |
| Change in physical functioning: single leg stand eyed closed | From baseline to end of 8-week training program and to end of 8-week follow-up | Maximal time to maintain balance on one leg with eyes closed, hands on hip and free leg bent to 90degrees flexion |
| Change in physical activity: percentage of time spent in sedentary activity levels | From baseline to end of 8-week training program and to end of 8-week follow-up | Accelerometer data captured and time spent in sedentary level expressed as a percentage of time worn. Accelerometers worn on right side waist for one week. |
| Change in physical activity: percentage of time spent in moderate to vigorous activity levels | From baseline to end of 8-week training program and to end of 8-week follow-up | Accelerometer data captured and time spent in moderate to vigorous level expressed as a percentage of time worn. Accelerometers worn on right side waist for one week. |
| Change in motivation towards physical activity | From baseline to end of 8-week training program and to end of 8-week follow-up | Behavioural Regulation in Exercise Questionnaire to measure motivation towards physical activity |
