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:48996 Wed 03 May 2023 11:21:02 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47514 Tue 30 May 2023 12:41:06 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54516 Tue 27 Feb 2024 15:45:57 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:35533 age = 15.82 years, SD = 0.37 years) completed: demographic information (survey), height (stadiometer), weight (digital scale), motor skill assessment (jog, grapevine, squat, push-up, upward dog, warrior one, tennis forehand, golf swing), health-related fitness (standing long jump, back-saver sit and reach, 3-min submaximal step test, 90° push-up test), and physical activity (GENEActiv accelerometers). Correlations and multiple regression models were conducted in SPSS version 24.0. Motor competence was associated with muscular fitness (standing long jump, β = 0.24, p = .002; push-ups, β = 0.42, p < .001), cardiorespiratory fitness (β = 0.21, p = .031), and flexibility (β = 0.23, p = .025), but not physical activity (β = 0.17, p = .154) or body mass index (β = -0.05, p = .622) Motor competence has a stronger association with health-relatedfitness parameters rather than physical activity.]]> Tue 27 Aug 2019 16:43:42 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42384 2peak) and heart rate (HR_peak) were recorded. There were no differences (p > 0.05) in mean VO_2peak among the three tests (min-max: 17.08–18.09 mL kg⁻¹ min^−1,). For individuals, small discrepancies in VO_2peak between the 6MWT and other tests were greater with higher fitness levels. HRpeak was significantly (p = 0.005) lower during the 6MWT. Correlations between VO_2peak and performance measures within each test were high (6MWT VO_2peak and distance: r = 0.78, SWT VO_2peak and shuttles: r = 0.73, cycle GXT VO_2peak and workload: r = 0.77) suggesting the performance measures may be clinically useful as proxy measures of CRF. Common comorbidities, such as lower-limb joint pain and poor balance, and participant’s fastest walking speed, should inform the choice of CRF test.]]> Tue 23 Aug 2022 11:15:21 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:35674 Tue 22 Oct 2019 11:50:11 AEDT ]]> 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:33482 squat, lunge and overhead press, whereas males performed better on the push-up (p < .05). Significant associations were seen for a number of correlates, which largely differed by sex. Muscular fitness was moderately and positively associated with RT skills among both males (ß = 0.34, 95%CIs = 0.23 to 0.46) and females (ß = 0.36, 95%CIs = 0.23 to 0.48). Our findings support a link between RT skills and muscular fitness. Other associations were statistically significant but small in magnitude, and should therefore be interpreted cautiously.]]> Tue 03 Sep 2019 18:18:06 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33481 Resistance Training for Teens was evaluated using a cluster RCT in 16 schools located in New South Wales, Australia. Adolescents (N = 508; 14.1 ± 0.5 years; 49.6% female) completed measures of global self-esteem, subjective well-being, and hypothesized mediators (i.e., perceived fitness, resistance training self-efficacy, and autonomous motivation) at baseline (April-June, 2015) and post-intervention (October-December). The school-based physical activity program was delivered by teachers over 10-weeks via Physical Education, co-curricular school sport, or an elective subject known as Physical Activity and Sport Studies, and involved once-weekly fitness sessions and additional lunch-time sessions. Intervention effects and moderator analyses were tested using multi-level linear regression analyses with interaction terms. Multi-level mediation analyses were used to explore potential mediators of changes in well-being outcomes. Results: Intervention effects for self-esteem (ß = 0.05, p =.194) and wellbeing (ß = 0.03, p =.509) were not statistically significant. Moderator analyses showed effects for self-esteem were greater for the overweight/obese subgroup (p =.069 for interaction), and resistance training self-efficacy was a significant mediator of changes in self-esteem (product-of-coefficients [AB] = 0.021, SE = 0.010, 95% CIs = 0.002 to 0.040). No other significant indirect effects were observed. Conclusion: Overall, Resistance Training for Teens did not improve adolescents' self-esteem or subjective well-being. However, our mediation findings lend support to resistance training self-efficacy as a mechanism explaining the positive effect of resistance training on self-esteem.]]> Tue 01 Sep 2020 14:18:41 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50034 Thu 29 Jun 2023 13:56:47 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37482 Thu 28 Jan 2021 17:29:50 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45012 2 tests). Results: Preference for an intervention group prior to randomization did not significantly (all P’s > .05 using 95% confidence interval) impact step counts (differences of <600 steps/day between groups) or study participation.
