Regarding the participants’ competence and autonomy need satisfaction, and autonomous motivation, the intervention effects were stronger in girls, compared with boys. Conclusions: Fitness infusion and game-like elements, used according to self-determination theory principles, can enhance students’ physical activity and motivation toward PE. This low-cost intervention has the potential to be scaled up and disseminated in secondary schools.]]> Thu 14 Jul 2022 08:52:17 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:20907 6500 counts/min). Secondary outcomes included sedentary behavior, cardiorespiratory fitness, overweight status, and blood pressure. Results: Among the 306 youth studied, those who reported spending most/all of their after-school time outdoors (n = 120) participated in more MVPA (61.0 ± 24.3 vs 39.9 ± 19.1 min/day; adjusted P < .001), were more likely to achieve the recommended minimum 60 min/day of MVPA (aOR 2.8; 95% CI, 1.3-6.4), spent less time in sedentary activities (539 ± 97 min/day vs 610 ± 146 min/day; adjusted P < .001), and had higher cardiorespiratory fitness (49 ± 5 vs 45 ± 6 mL/kg/min; adjusted P < .001) than youth who reported no time outdoors (n = 52). No differences in overweight/obesity or blood pressure were observed across the groups. Conclusions: Time spent outdoors is positively associated with MVPA and cardiorespiratory fitness in youth and negatively associated with sedentary behavior. Experimental trials are needed to determine whether strategies designed to increase time spent outdoors exert a positive influence on physical activity and fitness levels in youth.]]> Sat 24 Mar 2018 07:57:55 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38346 Mon 30 Aug 2021 15:53:18 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30354 N = 731 students; M = 14.38 years; all from Secondary 2) from 12 Hong Kong schools during September to December 2013. The primary outcome was percentage of lesson time spent in MVPA. Secondary outcomes included students' vigorous activity, counts per minute, perceived autonomy support and motivation for physical education. Accelerometer-based activity measures were taken from a sub-sample of 168 students during lessons 1 to 3 (baseline) and lessons 5 to 7 (treatment phase). Participants self-reported motivation variables at lessons 4 and 8. Teachers allocated to the experimental group included an intervention during treatment phase; those in the control group continued usual practices. The intervention involved a 15-minute rope skipping activity where students completed intervals of skipping with rests in between. Using multilevel modeling, we examined the intervention effects on measured outcomes, and whether effects differed for boys and girls. Overall intervention effects were not found. However, girls in the intervention group spent more time in MVPA (β = 0.25) and had higher counts per minute (β = 0.32) than control group counterparts at treatment phase. Perceived autonomy support and motivation variables were similar across groups. The intervention increased activity levels of girls, but not boys. Implementation of the intervention may reduce differences between boys' and girls' physical education activity levels.]]> Mon 29 Aug 2022 15:03:10 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36638 Mon 29 Aug 2022 13:38:28 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45971 Mon 26 Jun 2023 16:03:41 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47380 Mon 16 Jan 2023 13:46:52 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54192 Mon 12 Feb 2024 14:36:13 AEDT ]]>
