12. Background
Adaptive water skiing has grown into a popular recreational activity for people with disabilities who experience an increased quality of life when they can be involved in physically active recreational activities. In the Healthy People 2010 report there is a strong emphasis on the need for physical activity for all people because of its close relationship to health and well being. Enhancing the accessibility and safety of outdoor recreation activities, such as water skiing, for people with disabilities will ensure that they have access to all of the health benefits that a physically active lifestyle provides.
