Describe the relationships among research, program development, and policy initiative as they relate to the future of exercise science.

Exercise science professionals will continue to play an active role in research as greater insight into how improvements in individual health, the overall health of Americans, and effective and cost-efficient healthcare is delivered. Additional research will need to continue to occur at the cellular and molecular levels as we attempt to further understand the role of genetics and molecular responses to physical activity, physical inactivity, and exercise in both healthy and disease conditions. Moreover, as exercise science and allied health professionals work to enhance the health and reduce the disease risk of the clients and patients they work with, it will be important to expand effective programs and develop new and innovative intervention programs and examine the efficacy of those interventions. Numerous private and public organizations and businesses will continue to develop and implement programs at the local level for enhancing health and promoting chronic disease risk reduction. Additionally, federal and state governments and private organizations promote and support policy initiatives designed to enhance health and reduce disease risk. The development of sound policies includes having an infrastructure that provides sophisticated data collection and analysis, professional guidance, funding for the initiation of the policies, and an evaluation to assess the effectiveness of the policies.
