Teachers (N = 44; 48% female/52% male; mean ± SD years teaching experience = 10.6 ± 8.0) from 16 secondary schools were assessed at baseline. Intervention group teachers (i.e. from eight schools) delivered a structured school-based physical activity program over 10-weeks. Teacher outcomes included confidence to teach health-related fitness (HRF) activities, perceived barriers to teaching HRF activities, and perceived fitness. Detailed process evaluation data were also collected. Assessments were conducted at baseline and 6-months (post-program), and outcomes were assessed using repeated measures analysis of variance. Results: There was a positive group-by-time effect for the confidence composite score (p = .010, partial eta squared = 0.29), but no effects for the two (contextual, interpersonal) barrier composite scores. Also, there was a significant effect for perceived ‘general fitness’ (p = 0.044, partial eta squared = 0.13), but not for specific fitness subdomains. Teachers were highly satisfied with both the training and the program, believing it was beneficial for students. Resource usage and adherence to the SAAFE (Supportive, Active, Autonomous, Fair, Enjoyable) delivery principles was high. Conclusion: RT for Teens improved teachers’ confidence and perceived fitness. These findings highlight the potential for high-quality teacher training and program delivery to positively influence teacher-level outcomes. This may provide support for the use of teacher professional development to improve HRF-related pedagogy.]]> Wed 31 Aug 2022 08:19:25 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39520 Wed 27 Jul 2022 14:00:10 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45215 n = 541, 43% female) from 20 secondary schools who completed tests of inhibition (modified flanker task), working memory (n-back task), CRF (Progressive Aerobic Cardiovascular Endurance Run), and MF (standing long jump and push-up test). Multilevel analyses tested the association between CRF or MF and cognitive outcomes while accounting for the influence of the other fitness variable and relevant demographic factors. Results: CRF predicted response accuracy during incongruent flanker trials, the condition requiring greater inhibition. For the working memory task, CRF predicted greater target accuracy and greater d' scores on the 1-back task, requiring lesser amounts of working memory. In the 2-back task, which requires greater amounts of working memory, CRF also predicted greater target and non-target accuracy and d' scores. Comparatively, MF did not predict any cognitive outcomes after adjustment for CRF. Conclusion: CRF was selectively related to better performance during task conditions that require greater amounts of inhibition and working memory. This finding suggests that CRF, but not MF, may benefit cognitive control in older adolescents. This selective influence of CRF on older adolescents’ cognition highlights the value of aerobic physical activity.]]> Wed 26 Oct 2022 14:53:31 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46427 n = 4], diffusion tensor imaging [n = 3], arterial spin labeling [n = 1], and resting-state functional MRI [n = 1]) in which results for 5 distinct and 4 similar study samples aged 8.7 6 0.6 to 10.2 6 1.0 years and typically of relatively low socioeconomic status were reported. Effects were reported for 12 regions, including frontal lobe (n = 3), parietal lobe (n = 3), anterior cingulate cortex (n = 2), hippocampus (n = 1), and several white matter tracts and functional networks. Limitations: Findings need to be interpreted with caution as quantitative syntheses were not possible because of study heterogeneity. Conclusions: There is evidence from randomized controlled trials that participation in physical activity may modify white matter integrity and activation of regions key to cognitive processes. Additional larger hypothesis-driven studies are needed to replicate findings.]]> Wed 23 Nov 2022 10:19:18 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39145 N = 389, 16.0 ± 0.4 years, 41.10% female) completed the HIIT-SQ, and factorial validity of the measurement model was explored. Phase 3: Adolescents (N = 100, age 12–14 years, 44% female) completed the HIIT-SQ twice (1 week apart) to evaluate test–retest reliability. Confirmatory factor analysis of the final six items (mean = 3.43–6.73, SD = 0.99–25.30) revealed adequate fit, χ²(21) = 21, p = .01, comparative fit index = .99, Tucker–Lewis index = .99, root mean square of approximation = .07, 90% confidence interval [.04, .11]. Factor loading estimates showed that all items were highly related to the factor (estimates range: 0.81–0.90). Intraclass coefficients and typical error values were .99 (95% confidence interval [.99, 1.00]) and .22, respectively. This study provides preliminary evidence for the validity and reliability of scores derived from the HIIT-SQ in adolescents.]]> Wed 18 May 2022 12:22:41 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51020 Wed 16 Aug 2023 09:41:18 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:24278 Wed 11 Apr 2018 18:17:05 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:27083 2 h/day). In total, 322 adolescents (mean age = 14.4 ± 0.6 years) from eight secondary schools in New South Wales, Australia were recruited. The S4HM intervention was guided by Self-Determination Theory and included: an interactive seminar, eHealth messaging, a behavioral contract and parental newsletters. The primary outcome was recreational screen-time. Secondary outcomes included mental health (i.e., well-being, psychological distress, self-perceptions), objectively measured physical activity, and body mass index (BMI). Outcome analyses were conducted using linear mixed models and mediation was examined using a product-of-coefficients test. Results: At post-intervention, significant reductions in screen-time were observed in both groups, with a greater reduction observed in the intervention group (− 50 min/day versus − 29 min, p < 0.05 for both). However, the adjusted difference in change between groups was not statistically significant (mean = − 21.3 min/day, p = 0.255). There were no significant intervention effects for mental health outcomes, physical activity or BMI. Significant mediation effects for autonomous motivation were found. Conclusions: Participants in both the S4HM intervention and control groups significantly reduced their screen-time, with no group-by-time effects. Enhancing autonomous motivation might be a useful intervention target for trials aimed at reducing adolescents' recreational screen-time.]]> Wed 11 Apr 2018 16:06:47 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:15551 Wed 11 Apr 2018 15:44:54 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:18907 Wed 11 Apr 2018 15:25:21 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30990 Wed 10 Jul 2019 15:13:10 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29895 Wed 06 Nov 2019 12:48:57 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38654 Wed 06 Dec 2023 09:52:54 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:18557 Wed 04 Sep 2019 11:10:50 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:20688 Wed 04 Sep 2019 10:59:23 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:31353 Wed 04 Sep 2019 09:49:26 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:31067 Wed 04 Sep 2019 09:39:47 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41400 Wed 03 Aug 2022 10:35:27 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47514 Tue 30 May 2023 12:41:06 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29646 Tue 30 Aug 2022 15:09:28 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46750 Tue 29 Nov 2022 15:25:49 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46689 Tue 29 Nov 2022 09:35:58 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39549 Tue 26 Jul 2022 11:25:03 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50437 Tue 25 Jul 2023 19:15:59 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:15536 Tue 24 Aug 2021 14:37:58 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:35674 Tue 22 Oct 2019 11:50:11 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51132 Tue 22 Aug 2023 15:58:09 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51133 Tue 22 Aug 2023 15:57:59 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54327 Tue 20 Feb 2024 15:58:32 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41937 ecofit intervention will be evaluated using a two-arm randomized controlled trial. A total of 240 adults (aged 18-80) will be recruited and randomly allocated to either the ecofit intervention or a 'wait-list' control group. Both groups will have access to the two types of outdoor park exercise equipment, but the intervention group will be given access to the purpose-built ecofit app and a 90-min introductory group training session. To promote social support, participants can enrol in a group of up to four individuals and access the ecofit Facebook group. The ecofit app include workout plans that can be tailored to different locations, difficulty levels and workout-types (i.e., resistance-only or combined resistance and aerobic workouts). Outcome assessments will be conducted at baseline, 3- (primary-end point) and 9-months follow-up. The primary outcomes are upper and lower body muscular fitness. The secondary outcomes include physical activity, body composition, aerobic fitness, body mass index, self-report resistance-based physical activity, and mental health outcomes. The cost-effectiveness of the study will also be evaluated. Discussion: ecofit is an innovative, multi-component physical activity intervention that integrates smartphone technology, social support and the outdoor built environment to promote community-based aerobic and resistance-based physical. The findings will be used to guide future interventions and to support councils to promote community-based physical activity through the use of local outdoor exercise equipment.

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://nova.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://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36287 -1. The purpose of this study was to examine the effect of a school-based intervention focused on resistance training (RT) for adolescents. Methods: The "Resistance Training for Teens" intervention was evaluated using a cluster-randomized, controlled trial with 607 adolescents (50.1% girls; 14.1 T 0.5 yr) from 16 secondary schools. Teachers were trained to deliver the intervention, which included the following: (i) an interactive student seminar; (ii) a structured physical activity program, focused on RT; (iii) lunchtime fitness sessions; and (iv) Web-based smartphone apps. The primary outcome was muscular fitness (MF) and secondary outcomes included body mass index, RT skill competency, flexibility, physical activity, self-efficacy, and motivation. Assessments were conducted at baseline, 6 months (postprogram; primary end point), and 12 months (follow-up). Outcomes were assessed using linear mixed models, with three potential moderators tested using interaction terms (and subgroup analyses where appropriate). Results: For the primary outcome (MF), a group-time effect was observed at 6 months for the upper body (2.0 repetitions; 95% confidence interval (CI), 0.8-3.2), but not the lower body (-1.4 cm; 95% CI, -4.7-1.9). At 6 months, there were intervention effects for RT skill competency and self-efficacy, but no other secondary outcomes. Effects for upper body MF and RT skill competency were sustained at 12 months. Despite overall no effect for body mass index, there was a group-time effect at 12 months among students whowere overweight/obese at baseline (-0.55 kg·m^-2; 95% CI, -1.01 to -0.08). Conclusions: The school-based RT intervention resulted in immediate and sustained improvements in upper body MF and RT skill competency, demonstrating an effective and scalable approach to delivering RT within secondary schools.]]> Thu 19 Mar 2020 17:51:33 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48423 Thu 16 Mar 2023 14:11:10 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48087 Thu 16 Mar 2023 10:16:03 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48041 Thu 16 Feb 2023 13:59:00 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37626 Thu 11 Apr 2024 09:51:35 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:55272 Thu 09 May 2024 11:53:35 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:28372 Thu 04 Nov 2021 10:39:02 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:25396 Thu 03 Feb 2022 12:20:49 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:23923 Thu 03 Feb 2022 12:19:47 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:33483 Thu 03 Feb 2022 12:19:16 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:19227 Sat 24 Mar 2018 07:54:54 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46633 Mon 28 Nov 2022 15:37:23 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46627 Mon 28 Nov 2022 13:38:41 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:21859 Mon 23 Sep 2019 10:35:56 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50094 Mon 17 Jul 2023 10:30:00 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38647 Mon 06 Dec 2021 16:41:16 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48093 Fri 24 Feb 2023 15:24:02 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42182 Fri 19 Aug 2022 09:43:19 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39694 Fri 17 Jun 2022 16:14:05 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49955 Fri 16 Jun 2023 15:20:35 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47213 Fri 16 Dec 2022 10:09:24 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38430 Fri 10 Sep 2021 14:43:32 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:40370 Fri 08 Jul 2022 16:16:39 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49192 Fri 05 May 2023 15:51:19 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41494 Fri 05 Aug 2022 08:54:26 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36370 Fri 03 Apr 2020 13:29:31 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51361 Fri 01 Sep 2023 13:41:53 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51360 Fri 01 Sep 2023 13:41:32 AEST ]]>
