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.
