Answer:
The greatest challenge is how to change human behavior to promote health.
Explanation:
With the invention of new technologies that made our lives easier and simpler, we have become lazier and have changed their diets, replacing healthy food for quick and not nourishing meals. We dedicate more time to other activities where minimal movement is required. These habits have been forming since the last century along with new technologies and the changes in lifestyle. One of the greatest challenges is to change this unhealthy behavior and replace it for healthy habits throughout different plans, campaigns, and education.
Exercise programs and sports activities can differ in number of participants from one person doing an activity like jogging or swimming, to hundreds of participants at a track meet. Structure can be loose in solo exercises where you can set your own pace, or be very strict in most competitive sports. Competition varies from none to highly competitive, and can be on an individual or team level. More complex sports and activities can present a high skill level.
