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.

Physically active students are more likely to be fit and learn better in school than sedentary ones. For school-aged children, it is unclear whether physical fitness level is an important determinant for student’s activity afterschool. This study examined the association between health-related physical fitness test performance and afterschool physical activity during weekdays. Participants (n = 97, 11–13 years old) completed health-related fitness tests. They wore Actigraph GT3X accelerometers for five consecutive days, recording physical activity participation during after school hours. Descriptive statistics for both afterschool physical activity and health-related fitness were summarized. Regression analyses were conducted to determine the association between variables. Participants spent most of their afterschool hours participating in sedentary behaviors (274.27 ± 66.89 min) and light physical activity (73.68 ± 51.66 min), and only 11.35 ± 16.92 min of moderate-to-vigorous physical activity (MVPA), accumulating approximately 2058.52 ± 1690.56 steps each day afterschool. The regression model explained 22.8% of the variance in afterschool MVPA, and Progressive Aerobic Cardiovascular Endurance Run (PACER) scores were the only statistically significant predictor (β = 0.47, p < 0.01). Fit students do tend to exercise more after school. Promoting physical fitness in school is an important factor for students’ afterschool physical activity participation during weekdays.

Purpose:Activity trackers are useful tools for physical activity promotion in adolescents, but robust validity evaluations have not been done under free-living conditions. This study evaluated the validity of the Garmin Vívofit 1 (G1) and Garmin Vívofit 3 (G3) in different settings and contexts.Methods:The participants (girls: 52%, age: 15.9 [1.9] y) wore the G1 and G3 on their nondominant wrist and the Yamax pedometer on their right hip for a period of 1 week. Validity was examined in 4 discrete segments (before school, in school, after school, and whole day). The criterion method was the Yamax pedometer.Results:Both the G1 and G3 could be considered equivalent to the Yamax pedometer regarding the before school, in school, and whole day segments. The G1 showed wider limits of agreement than G3.Conclusions:The G1 and G3 trackers exhibited acceptable validity for 3 of the 4 segments (before school, in school, and whole day measurements). The results were less accurate during the after-school segment. The evidence that the validity of the monitors varied depending on the setting and context is an important consideration for research on adolescent activity patterns.

This study describes age, sex, and season patterns in children’s physical activity behaviors during discrete time periods, both in school and at home. Participants were 135 elementary, 67 middle, and 89 high-school students (128 boys and 163 girls) involved in a larger school activity monitoring project. We examined time spent in moderate-to-vigorous physical activity (MVPA) at recess, physical education (PE), lunch, commuting to/from school, before-school, after-school, evening, and weekend segments. Differences in MVPA by age, sex, and season were examined using a three-way analysis of variance and separately for each individual segment. Moderate-to-vigorous physical activity levels varied by context and were higher during recess (15.4 ± 8.5 min) while at school, and on Saturdays (97.4 ± 89.5 min) when youth were out-of-school. Elementary children were more active than their older counterparts only during lunch time, after-school, and Sunday (p < 0.05). Boys were consistently more active than girls at all segments. Participants were only more active during non-winter than winter months during PE (p = 0.006), after-school (p < 0.001), and Sunday (p = 0.008) segments. These findings showed that activity levels in youth vary during the day and season. The segments reflect discrete time periods that can potentially be targeted and evaluated to promote physical activity in this population.

Background: Since less than one-third of 13-year-olds in many Western countries meet the physical activity guidelines, there is a major need to promote physical activity. The aim of this study was to examine children’s segment specific moderate to vigorous physical activity (MVPA) through the school-initiated program. Material/Methods: The sample comprised 76 Finnish elementary school children. Accelerometers were used to investigate the patterns of segmented MVPA through 2012-2014. Repeated Measures Analysis was implemented to summarize variability between time and segments of MVPA. Results: The examination of children’s MVPA revealed that their total, weekend, and before-school activity were significant predictors for their subsequent activity. Children’s MVPA in physical education classes, before- and after-school, and during school breaks decreased through the program. Both girls and boys accumulated the majority of their weekly MVPA during weekdays and out-of-school. Conclusions: The program provedto be effective in order to sustain children’s total MVPA levels, although physical education, before- and after-school, and recess MVPA decreased through the program. Out-of-school activities seemed to be more important than in-school activities in relation to children’s total MVPA minutes, when they transfer to the higher grades. Attention should be paid to out-of-school, especially weekend, activities.

Levels of physical activity and sedentary behavior among adolescents seem to vary within different settings, but few Asian studies have compared physical activity and sedentary activity patterns in adolescents across weekdays/weekends and during-school time/after-school time. This study aimed to provide objectively measured data describing intensity-specific physical activity and sedentary behavior patterns in Taiwanese adolescents. The results were sorted by gender and divided between weekdays/weekends and during-school time/after-school time. A total of 470 Taiwanese students (49.6% boys, ages 12–15 y) were recruited and fitted with GT3X+ accelerometers for seven days. Intensity-specific physical activity, total sedentary time, and sedentary bouts (number and duration ≥30 min) were measured. The Mann-Whitney U test was used to examine the significant differences in physical activity and sedentary behavior patterns between the genders on weekdays/weekends and during school/after-school time. The results show that the adolescents’ overall activity levels were below recommended thresholds, with girls engaging in significantly less moderate to vigorous physical activity, having longer sedentary time, longer time spent in sedentary bouts, and more frequent sedentary bouts than boys. Similar results were observed in physical activities of each intensity as well as sedentary behavior variables, both on weekdays/weekends and during-school/after-school periods. These findings emphasize the importance of developing and implementing approaches to increase moderate to vigorous physical activity, as well as decrease prolonged sedentary time and long sedentary bouts, especially for Taiwanese girls.

Introduction Youths with visual impairments (that is, those who are blind or have low vision), as well as those who are visually impaired and have autism spectrum disorder (hereafter, autism), tend to be physically inactive and have low health-related fitness. However, little is known about individuals with dual disabilities, such as those with autism and visual impairments. Thus, the aim of this study was to perform an initial exploration of physical activity and health-related fitness for these students in comparison to students with visual impairments alone. Methods Twelve participants (six with visual impairments, six with autism and visual impairments) aged 8–16 years (Mage = 12.4) who came from a school for students with visual impairments were participants. Participants wore tri-axial accelerometers on their right hips for four consecutive weekdays, during waking hours, to measure weekday physical activity. Following that task, they completed four health-related fitness tests, including a half-mile walk or run to measure aerobic endurance, a push-up test to measure upper-body muscular endurance, a modified curl-up test to measure abdominal muscular endurance, and a sit-and-reach test to determine flexibility. Data were analyzed using descriptive statistics and independent sample t-tests to identify differences between groups. Results On average, the participants accrued 650.17 ± 141.44 minutes of sedentary time, 129.80 ± 66.78 minutes of light physical activity, and 19.78 ± 3.35 minutes of moderate-to-vigorous physical activity per weekday. No participants met the 60-minute recommendations of daily moderate-to-vigorous physical activity. Participants with autism and visual impairments were significantly less physically active (p = .02) and less likely to pass fitness tests (p = .01) than were their peers with visual impairments alone. Discussion This study provides the first empirical exploration of health-related variables for youths with autism and visual impairments. It is clear that developing and implementing interventions to help enhance physical activity and health-related fitness for those youths are needed. Implications for practitioners Additional training and resources to understand the unique needs of these youths are essential in providing opportunities to participate in physical activities and enhancing health-related physical fitness.
