Read the passage carefully and answer the question as per the content:
Man is a social animal and always social by nature. This social nature has a great impact on physical activities. Sports and physical activities can also be considered as cultural heritage of mankind. Understanding the many factors that influence physical activity may help im- prove the effectiveness of physical activity intervention programmes. Research suggests that the effectiveness of programs should be maximized when participant’s confidence about their ability to continue physical activities is nurtured. They enjoy the activities they have chosen, receive encouragement and assistance from the other people in their lives, and reside in a supportive environment that provides convenient, attractive, and safe places for physical activity. A person becomes active on a regular basis by participation in physical activity, but some personality traits are inherited. No social influences on physical activity are strong for people of all ages, but the nature of the support varies with development level. Remarkably, social support for adults can come from friends, co-workers, or family members in the form of encouragement, participation in physical activities, and providing assistance, such as child care.
For adolescents, the influence of peers is of great importance. But development is possible only through the means of co-operation, competition, and enthusiasm. Within the competitive structure of many physical activities and sports experiences, there are countless opportunities for teaching important social values. For example-winning, losing, success, failure, rejection, anxiety, fair play, acceptance, friendship, cooperation, etc.
