Design: Assessor-blinded randomized controlled trial. Methods: Ninety-six students (15.4 (0.5) years, 51.5% female) from one NSW secondary school, Australia 2013, were randomized into the 8-week CrossFit^TM Teens intervention (n = 51) or control conditions (n = 45). Measures of mental health (psychological distress and self-esteem) were assessed using the Strength and Difficulties Questionnaire and Physical Self-Description Questionnaire. Hypothesized mediators were perceived body fat, strength and appearance; and general physical self-concept. Mediation was assessed using Preacher and Hayes' multiple mediation regression SPSS macro. Hypothesized moderators (sex and baseline levels of psychological distress) were assessed using linear mixed models and Cohen's d effect sizes were evaluated. Results: There were no significant intervention effects on mental health or potential mediators in the full study sample. Intervention participants categorized as 'at risk' of psychological distress demonstrated improvements in self-esteem (d = 1.35); perceived body fat (d = 1.05), perceived appearance (d = 0.95); physical self-concept (d = 1.96); and total difficulties score (d = 0.70). A medium-large positive effect on perceived body fat was also observed in boys. Conclusions: Participation in the CrossFit^TM Teens resistance training program did not improve mental health outcomes in the full study sample. However, the results from this study provides preliminary evidence for improving mental health in adolescents 'at risk' of developing psychological disorders.]]> Wed 04 Sep 2019 10:18:32 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37695 Tue 14 May 2024 09:47:57 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30960 Tue 04 Jun 2019 13:26:08 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:19452 Sat 24 Mar 2018 08:02:25 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:17982 Sat 24 Mar 2018 07:56:19 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:21370 n = 93) from the control group (standard PA materials, n = 44) and the full intervention group (control + stage-matched printed material and telephone counseling, n = 49) of a larger PA intervention trial were included. PA outcomes were minutes of MET weighted moderate and vigorous PA/week (self-report) and steps/3-days (objective) recorded at baseline and 12-months. Social-cognitive constructs were measured and tested in a mediating variable framework. Results: Perceived behavioral control and barrier self-efficacy mediated intervention effects on objective PA (proportion of intervention effect mediated = 18% and 24% respectively). Intention was a mediator of objective PA (23%). Conclusion: Perceived behavior control, barrier self-efficacy, and intention are effective mechanisms of PA behavior change in women with T2DM.]]> Sat 24 Mar 2018 07:51:26 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:23156 Sat 24 Mar 2018 07:10:34 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38647 Mon 06 Dec 2021 16:41:16 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51391 Mon 04 Sep 2023 13:47:42 AEST ]]>
