How Does Physical Activity Impact Postural Stability?

Kathleen S Thomas and Meir Magal

Physical activity has been associated with an overall improvement in health by reducing disease and assisting in weight management. However, varying levels of physical activity has been shown to have immediate adverse effects on measures of postural stability. Increases in postural sway occur as a result of performing fatiguing exercise to specific muscles in addition to moderate to maximal intensity exercise. While this is often not problematic for healthy young adults this could produce challenges to individuals with balance impairments and older adults. This review investigates the immediate impact that various physical activity levels have on postural stability. In addition, the areas that require further investigation will be highlighted.
