Federal guidelines state that youth should participate in a variety of physical activity (PA) they find enjoyable. Little is known, however, about how variety and enjoyment are associated with PA participation among adolescents.
Data came from the 2010 National Youth Physical Activity and Nutrition Survey, a nationally representative survey of adolescents. Path analysis was used to examine the association of a variety of self-reported PA, defined as the number of activities and activity types (ie, team sports/weightlifting, individual activities, and other competitive/recreational sports), on self-reported PA enjoyment and participation. The analysis also examined whether enjoyment mediates the association between a variety of PA and participation. Separate models were estimated for boys and girls.
Number of activities was associated with increased PA enjoyment and participation. For boys and girls, team sports/weightlifting was associated with increased participation, and individual activities were indirectly associated with increased participation through enjoyment. For boys, team sports/weightlifting was indirectly related with participation.
These findings suggest that participation in a variety of PA is associated with increased PA enjoyment and participation. Providing opportunities for adolescents to engage in a variety of activities might help them identify PA they enjoy and facilitate lifelong PA habits.

For interventions to be implemented effectively, fidelity must be documented. We evaluated fidelity delivery, receipt, and enactment of the 48-week Women’s Lifestyle Physical Activity Program conducted to increase physical activity and maintain weight in African American women.
Three study conditions all received 6 group meetings; 1 also received 11 motivational interviewing personal calls (PCs), 1 received11 automated motivational message calls (ACs), and 1 received no calls. Group meeting delivery was assessed for adherence and competence. PC delivery was assessed with the Motivational Interviewing Treatment Integrity Code. Receipt was defined as group meeting attendance, completion of PCs, and listening to ACs. Enactment was number of weeks an accelerometer was worn.
For group meeting delivery, mean adherence was 80.8% and mean competence 2.9 of 3.0. Delivery of PCs did not reach criterion for competence. Receipt of more than one-half the dose was achieved for 84.9% of women for group meetings, 85.5% for PCs, and 42.1% for ACs. Higher group meeting attendance was associated with higher accelerometer steps at 24 weeks and lower BMI at 24 and 48 weeks.
Fidelity measurement and examination of intervention delivery, receipt, and enactment are important to explicate conditions in which interventions are successful.
