Greater variability in daily physical activity is associated with poorer mental health profiles among obese adults
This study employed a novel two-stage data analysis approach using the standalone program MIXWILD. The first-stage model partitioned mean level as well as between-subject and within-subject variances in daily PA by estimating a random location (subject-level mean) and a random scale (subject-level variability) for daily PA. In the second-stage, these random subject effects for daily PA along with their interactions with BMI were used as predictors for subject-level mental health outcomes. Associations between subject-level variability in daily PA and mental health outcomes significantly differed depending on adults’ BMI ...

Stress and self-esteem in adolescence predict physical activity and sedentary behavior in adulthood
Publication date: Available online 1 March 2018 Source:Mental Health and Physical Activity Author(s): Jocelyn Smith Carter High levels of stress, high levels of sedentary behavior (SB), and low levels of physical activity (PA) contribute to risk for obesity. Cross-sectional studies suggest that youth exposed to more stressors are less likely to be physically active and more likely to be sedentary. However, it is not yet clear whether stressors in adolescence predict activity patterns into adulthood or protective factors mitigate the risk of stress exposure. The current study used data from the National Longitudinal Stud...

Feasibility and acceptability of a home-based physical activity program for postnatal women with depressive symptoms: A pilot study
Conclusion A home-based physical activity program involving cost-free exercise equipment hire was feasible and well accepted by postpartum women. The effectiveness of this program for increasing physical activity and improving mental health in this population should be further tested. (Source: Mental Health and Physical Activity)

A single bout of either sprint interval training or moderate intensity continuous training reduces anxiety sensitivity: A randomized controlled trial
We examined the effects of a single session of either SIT or MICT on AS, distress tolerance (DT), and intolerance of uncertainty (IU). A total of 56 participants were randomized into either a 50-min MICT group, a 10-min SIT group, or a waitlist control group. AS, DT, and IU were measured at baseline, post-exercise session, and at 3-day and 7-day follow-ups. Both exercise groups experienced similar reductions in AS; however, these changes appeared attributable to reductions across different AS dimensions. Specifically, significant reductions in the AS Physical Concerns were noted in the SIT group whereas the MICT group expe...

Psychosocial health is associated with objectively assessed sedentary time and light intensity physical activity among lung cancer survivors
Conclusions Sedentary time and light intensity physical activity were significantly associated with some psychosocial health outcomes. Reducing sedentary time and increasing light intensity physical activity may be a more appropriate recommendation for many lung cancer survivors given their older age, poorer functional status, and reduced pulmonary capacity.

Mental health practitioners ’ reported barriers to prescription of exercise for mental health consumers
Publication date: Available online 10 January 2018 Source:Mental Health and Physical Activity Author(s): Kirsten Way, Lee Kannis-Dymand, Michele Lastella, Geoff P. Lovell Exercise is an effective evidenced-based intervention for a range of mental health conditions, however sparse research has investigated the exercise prescription behaviours of mental health practitioners as a collective, and the barriers faced in prescribing exercise for mental health. A self-report survey was completed online by 325 mental health practitioners to identify how often they prescribe exercise for various conditions and explore their pe...

The relationships between off-job physical activity and vigor at work across time: Testing for reciprocity
Conclusion The findings suggest that high vigor at work has the potential to prompt individuals to engage in off-job MVPA. Conversely, in the present study high levels of off-job MVPA were not linked to enhanced vigor at work. As a result, strategies designed to enhance vigor at work may result in higher levels of off-job MVPA and in the long term to the adoption of a healthy lifestyle beneficial for physical and mental health.

Mediators of aggression in a school-based physical activity intervention for low-income adolescent boys
Conclusion Limiting recreational screen-time may help to reduce aggression in adolescent boys. Interventions targeting adolescents' recreational screen-time should examine their ‘flow-on’ effects on externalising behaviours in adolescent populations. (Source: Mental Health and Physical Activity)

Improving children's physical self-perception through a school-based physical activity intervention: The Move for Well-being in School study
Conclusions Despite limited overall intervention effects on self-perceived competence and self-worth, the intervention appeared to diminish the gap between those groups with most and those with least self-confidence. Even though many of the new activities and approaches were implemented, some teachers were challenged to create a positive social climate. (Source: Mental Health and Physical Activity)

Greater specificity of activity memories in Chronic Fatigue Syndrome/Myalgic Encephalomyelitis: Implications for exercise-based treatment
Conclusion CFS/ME individuals’ autobiographical memory for activity differs both from healthy individuals and the typical pattern found in depression. The effect of specific activity memories could be utilized in exercise-based treatment of CFS/ME. (Source: Mental Health and Physical Activity)

A systematic review and meta-analysis of the effect of exercise on psychosocial outcomes in adults with obesity: A call for more research
Conclusions Current evidence does not suggest exercise is successful in significantly enhancing psychosocial health in adults with obesity. Limitations associated with the reviewed studies could have biased the results toward a lack of effect. Additional high-quality RCTs are needed to improve evidence-based knowledge.

Reciprocal relationship between sedentary behavior and mood in young adults over one-year duration
Conclusion These results indicate a reciprocal relationship between mood and SED suggesting that a decrease in SED can improve mood, likewise, an improved mood may decrease SED. However, the stronger association is mood status predicting time spent in SED. (Source: Mental Health and Physical Activity)
