What did I do?

The overarching aim of this PhD was to characterise and profile children’s physical activity movement quality. Further, chapter specific aims were, (1) to verify the validity and reliability of accelerometry in a mechanical and laboratory setting, (2) to characterise and profile movement quality according to body mass index (BMI) and (3) to characterise and profile movement quality during recess and free play.

Why did I do it?

Regular physical activity during childhood is positively associated with a variety of physical, social and psychological factors.1–3 While there are a plethora of methods and techniques to quantify overall activity or energy expenditure, there is a paucity of research demonstrating objective methods to empirically derive quality of movement and its relationship with health, performance and risk factors.4
