Physical Activity and Health-Related Fitness of Adolescents within the Juvenile Justice System

Background. The purpose of this study was to examine the physical activity patterns and health-related fitness levels of adolescents within the Juvenile Justice System. Methods. Participants included 68 adolescents (Mean age = 17.1 ± 1.0 years) in two secure Juvenile Justice correctional facilities in the Western USA. Moderate-to-vigorous physical activity (MVPA) was monitored for one week using the ActiGraph GT9X accelerometer. Health-related fitness was measured using the FITNESSGRAM test battery. Results. Adolescents averaged 43.3±21.6 minutes of MVPA per weekday compared to 42.7±27.5 per weekend day. During school hours, adolescents accumulated 17.1±9.0 minutes of MVPA compared to 5.9±3.4 minutes before school and 21.0±13.6 minutes after school. Adolescents averaged 18.9±11.0 push-ups, 44.5±26.4 curl-ups, 34.7±24.8 PACER laps, and 22.1%±10.0% body fat. Conclusions. Adolescents within the Juvenile Justice System are falling short of the recommended 60 minutes of MVPA per day and 30 minutes of MVPA during school and also need to improve their health-related fitness, especially cardiorespiratory endurance.
