Background
Affective states influence subsequent engagement in physical activity, but the nature of this relationship varies substantially from person-to-person (e.g., negative affect may precede increased physical activity for some adolescents and decreased for others).
Purpose
Explore which variables may explain the individual differences in the relationship between incidental affect and moderate to vigorous physical activity (MVPA).
Methods
This study explores social cognitive variables as moderators of the relationship between incidental affect and MVPA through a 20-day ecological momentary assessment (EMA) study, in which 100 adolescents aged 13–18 years old (M = 14.45, SD = 1.37) were asked to complete a baseline assessment of their self-efficacy and outcome expectancies. Subsequently, wore an Actigraph (wGT3X-BT) accelerometer 24 h per day on their non-dominant wrist and answered EMA surveys assessing affect 4 times per day using time-based signaling.
Results
Within-person negative affect predicted MVPA (b = −0.15 p < .05) with 95% CI [-0.29, −0.01], as did between-person negative affect (b = 0.08 p < .05) with 95% CI [0.01, 0.15]. Additionally, there was a significant interaction between within-person negative affect and self-efficacy such that for individuals low in self-efficacy (<2.08 on a 5-point scale) increased negative affect led to decreased MVPA (b = −0.06, p < .05), but not for individuals high in self-efficacy (>5.14 on a 5-point scale; b = 0.07, p < .05).
Conclusions
Results indicate that self-efficacy is an important target for overcoming the deleterious effects of momentary negative affect on MVPA and suggests just-in-time intervention techniques for individuals who are typical or low in self-efficacy.

Background
Recovery from substance use disorders is multifactorial with psychosocial functioning, such as quality of life (QOL), playing a particularly important role. Delay discounting, the degree to which individuals devaluate a reinforcer as a function of the delay to its receipt, is associated with QOL. Moreover, evidence shows that physical activity may decrease delay discounting rates. The present study aims to examine associations among physical activity, delay discounting, and QOL, and investigate the mediating role of delay discounting in the relationship between physical activity and QOL domains.
Methods
Data was collected from the International Quit & Recovery Registry (IQRR), and comprised of 267 participants (67% women) who reported being in recovery from substance use disorders. Participants completed the Health Behaviors Questionnaire (physical activity was measured using the fitness domain), a delay discounting minute task (higher delay discounting rates indicate a preference for smaller, sooner rewards), the World Health Organization QOL questionnaire, as well as demographics and substance use disorders-related questions. Multivariate linear regression was used to test associations between physical activity with delay discounting, and physical activity with each QOL domain. Mediation analyses were conducted to evaluate the mediating role of delay discounting in the relationship between physical activity and QOL domain.
Results
Higher levels of physical activity were associated with greater valuation of the future (lower delay discounting rates; p < .001) and higher levels of physical (p < .001), and environmental (p = .001) QOL. Delay discounting mediated the relationship between physical activity and physical (p = .004), and environmental (p < .001) QOL.
Conclusion
Physical activity can be an important tool in the treatment and recovery of substance use disorders, as it is associated with future-oriented choices, which in turn contributes to improving the QOL of those individuals.
背景药物使用障碍的康复是多因素的，其中社会心理功能，如生活质量（QOL），起着特别重要的作用。延迟折现是指个体对强化物的贬值程度与获得强化物的延迟程度成函数关系，而延迟折现与生活质量相关。此外，有证据表明，体育锻炼可降低延迟折现率。本研究旨在考察体育锻炼、延迟折现和 QOL 之间的关联，并研究延迟折现在体育锻炼和 QOL 领域之间关系中的中介作用。方法数据收集自国际戒烟与康复登记处（IQRR），由 267 名报告正在从药物使用障碍中康复的参与者（67% 为女性）组成。参与者完成了健康行为调查问卷（使用健身领域测量体育活动）、延迟折现分钟任务（较高的延迟折现率表明偏好较小、较快的奖励）、世界卫生组织 QOL 问卷以及人口统计学和药物使用障碍相关问题。多变量线性回归用于检验体育锻炼与延迟折现之间的关系，以及体育锻炼与各 QOL 领域之间的关系。结果较高水平的体育锻炼与较高的未来评价（较低的延迟折现率；p = .001）和较高水平的身体（p = .001）和环境（p = .001）QOL相关。结论：体育活动可以成为药物使用障碍治疗和康复的重要工具，因为它与面向未来的选择有关，而面向未来的选择反过来又有助于改善这些人的 QOL。

Executive functioning is said to be fundamental to human cognition and achievement. This meta-analysis aimed to establish what effect – if any – yoga delivered in school-settings has upon the executive functioning skills of children between three and seven years of age.
Procedure
Databases screened were PubMed Central, Web of Science, CINAHL, Scopus, and PsycARTICLES. Studies involving a yoga-based intervention alongside a control group, and age-appropriate measures of executive functioning were included. In total, seven studies, involving 1080 participants, met the inclusion criteria.
Findings
Meta-analysis of all seven studies demonstrated a significant (p < 0.001) small positive weighted average effect size (Cohen's d) of 0.24 [95% CI 0.10, 0.39], evidencing that yoga may improve the executive functioning skills of children between three and seven years of age. Sub-group meta-analyses to examine the different domains of executive functioning (working memory, inhibitory control, and cognitive flexibility) revealed a significant (p = 0.007) small positive effect size (Cohen's d) of 0.41 [95% CI 0.11, 0.70] for working memory, and a significant (p = 0.033) marginal positive effect size (Cohen's d) of 0.18 [95% CI 0.01, 0.34] for inhibitory control. However, there were insufficient data for a sub-group meta-analysis of cognitive flexibility.
Conclusions
Results are discussed in the context of ‘hot’ and ‘cold’ executive functioning skills. Study limitations are considered, and it is acknowledged that further high-quality research is needed into the effect(s) of school-based yoga on executive functioning within this population before definitive conclusions can be drawn.
目的 据称，执行功能是人类认知和成就的基础。本荟萃分析旨在确定在学校环境中教授瑜伽对 3 到 7 岁儿童的执行功能技能有何影响（如果有的话）。纳入的研究包括基于瑜伽的干预措施和对照组，以及与年龄相适应的执行功能测量方法。研究结果对所有七项研究进行的荟萃分析表明，加权平均效应大小（Cohen's d）为 0.24 [95% CI 0.10, 0.39]，具有显著性（p < 0.001），证明瑜伽可以改善三至七岁儿童的执行功能。对执行功能的不同领域（工作记忆、抑制控制和认知灵活性）进行的分组荟萃分析显示，工作记忆有显著的（p = 0.007）小正效应（Cohen's d），为 0.41 [95% CI 0.11，0.70]；抑制控制有显著的（p = 0.033）边际正效应（Cohen's d），为 0.18 [95% CI 0.01，0.34]。然而，对认知灵活性进行分组荟萃分析的数据不足。我们考虑了研究的局限性，并承认在得出明确结论之前，还需要进一步开展高质量的研究，以了解校本瑜伽对这一人群的执行功能的影响。

Physical activity is associated with lower risk of incident depression and anxiety disorders. However, there is no meta-analytic evidence on the associations between physical activity levels and the incident use of psychotropic medications. PubMed, Embase, Scopus, Web of Science, PsycINFO, and Cochrane were searched up until March 2024 to identify prospective cohort studies in the general population without age restrictions, with any sample size, and with at least one year of follow-up. Risk of bias was assessed using the Newcastle-Ottawa Scale and a random-effects meta-analysis of adjusted relative risks was performed. Three studies comprising 40,111 participants and 322,521 person-years were included (mean age 53.8, range 18–90 years; 54% women). Relative to people reporting no physical activity, those accumulating any volume of physical activity had 15.0% (95% CI: 0.76, 0.96) lower risk of any subsequent medication use. Heterogeneity was moderate and not significant (I2 = 33.6%). The current meta-analysis demonstrated that people with higher physical activity levels are at lower risk of subsequent use of psychotropic medication. However, the evidence is based on a small number of studies (n = 3), highlighting the need for high-quality longitudinal studies.

Background and aims
Exergaming combines physical and cognitive exercises, can enhance cognitive functions by increasing attentional demand. Similarly, balance training on unstable surfaces elevates cognitive-motor challenges. By integrating exergaming of varying difficulty levels with unstable surface balance training, cognitive processing, and neurocognitive functions may be further improved. This study compared the effects of novel exergame balance training of mild, moderate, high difficulty, and control groups for global cognition, cognitive flexibility, inhibitory control, recall ability, working memory, and attention in adults with MCI.
Methodology
In this four-armed parallel design randomized clinical trial, ninety-seven adults with MCI were randomly assigned to exergame balance training groups of mild, moderate, high difficulty, and control. The difficulty levels were determined by adjusting the size of the goal spot (large, medium, small) and the speed of moving the ball (fast, moderate, slow) in the exergame. All participants received 40 min/session three times/week for eight weeks. Montreal cognitive assessment (MoCA), Trail making test (TMT), Stroop colour word test, Stroop colour word test errors, ADAS word list, digit span forward and backward test, and count backward test were used to assess cognitive abilities. Assessment was conducted at baseline, after the 4th and 8th week. Mixed model ANCOVA, One-way ANOVA, and repeated measure ANOVA were used to determine group × time interaction, between, and within-group effects. Minimal clinical important difference (MCID) responders proportion analysis was conducted to determine clinical improvement.
Results
There was significant time × group interaction for MoCA, Stroop Colour word, Stroop Colour word Error, Digit span, and counting backward test (p < 0.05). Post-hoc analysis at difficulty level depicted no significant difference between mild, moderate, and high difficulty groups (p > 0.05), while a significant difference between mild, moderate, and high difficulty groups with the control group for MoCA, ADAS word list, digit span, and count backward task (p < 0.05) was observed.
Conclusion
The results concluded no significant difference between exergame balance training of mild, moderate, and high difficulty groups for various cognitive functions. Furthermore, differences were observed between the mild, moderate and high-difficulty groups and the control group for global cognition, inhibitory control, and attention. Additionally, the high-difficulty group showed greater clinical improvement in various cognitive functions.

Background and aims
Vocational education and training (VET)-students often face student mental well-being (SMW) challenges. Physical activity behaviour (PAB) is positively associated with SWM, yet SMW can vary during the day. Therefore, this study aims to explore the momentary relationship between PAB ((i.e., moderate to vigorous physical activity (MVPA), light physical activity (LPA), sedentary behaviour (SB)) and SMW (i.e., affect, self-esteem).
Methods
For 9 consecutive days, VET-students reported their SMW via experience sampling methods-prompts while their PAB was measured with thigh worn ActivPALs™. PAB data was summed in minutes spent in each PAB 30 and 60 min before each prompt. Data of 68 students (68% female, mean-age = 18.9 ± 4) was analysed with multilevel regression analyses.
Results
Consistently positive associations between LPA and positive affect (30min: β = 0.03, p = <0.001, 60min: β = 0.03, p = <0.001), and self-esteem (30min: β = 0.01, p = .047 60 min: β = 0.01, p = <0.001) were found. For SB negative associations for positive affect (30 min: β = −0.04, p = <0.001, 60 min: β = −0.03, p = <0.001), and self-esteem (30 min: β = −0.02, p = < 0.001, 60 min: β = −0.01, p = < 0.001) were found. No associations were found between any PAB and negative affect, and for MVPA and SMW.
Conclusion
The significant positive associations between LPA and SMW and the negative associations between SB and SMW suggest that increasing LPA and decreasing SB and can improve SMW in VET students.

Purpose
Resistance exercise (RE) can acutely benefit symptoms in individuals with methamphetamine use disorder (MUD), though the optimal dose has not yet been established. We aimed to determine the dose response relationship between RE intensity and cue-elicited cravings and executive functions in individuals with MUD.
Methods
A total of 128 male participants with MUD (34.73 ± 5.65) were randomly assigned to the low-intensity (30%–35%1-RM) RE group (LREG), moderate-intensity (55%–60%1-RM) RE group (MREG), high-intensity (75%–80%1-RM) RE group (HREG), or control group (CONG). Cravings based on the cue-reactivity paradigm were measured before, immediately after, and 40 min after acute RE, and inhibitory control, working memory, and cognitive flexibility were measured before and after acute RE.
Results
Immediately after and 40 min after RE, the Δcue-elicited cravings of the MREG from baseline was significantly more negative than that of the LREG and CONG. Trend analyses revealed a U-shaped dose‒response curve for RE intensity and Δcue-elicited cravings, indicating that moderate-intensity RE had the greatest ameliorating effect on cue-elicited cravings. Δinhibitory control and Δworking memory scores increased only in the MREG, and Δcognitive flexibility scores significantly increased in all RE groups. Trend analyses revealed a cubic curvilinear relationship between RE intensity and inhibitory control and a quadratic curvilinear relationship with working memory and cognitive flexibility.
Conclusion
RE proved effective in diminishing cue-elicited cravings and enhancing executive functions. A significant dose‒response relationship existed among RE intensity, cue-elicited cravings and executive function, and moderate-intensity RE had a more pronounced ameliorative effect on individuals with MUD.
目的抵抗运动（RE）可迅速改善甲基苯丙胺使用障碍（MUD）患者的症状，但最佳剂量尚未确定。方法将128名男性MUD参与者（34.73 ± 5.65）随机分配到低强度（30%-35%1-RM）RE组（LREG）、中等强度（55%-60%1-RM）RE组（MREG）、高强度（75%-80%1-RM）RE组（HREG）或对照组（CONG）。在急性 RE 之前、之后和之后 40 分钟测量了基于线索反应范式的渴求度，并在急性 RE 之前和之后测量了抑制控制、工作记忆和认知灵活性。趋势分析显示，RE强度和Δ线索诱发的渴求度呈U形剂量反应曲线，表明中等强度的RE对线索诱发的渴求度具有最大的改善作用。Δ抑制控制和Δ工作记忆得分仅在MREG中有所提高，而Δ认知灵活性得分在所有RE组中都有显著提高。趋势分析表明，RE 强度与抑制控制之间存在立方曲线关系，与工作记忆和认知灵活性之间存在二次曲线关系。RE 强度、线索诱发的渴求和执行功能之间存在明显的剂量-反应关系，中等强度的 RE 对 MUD 患者有更明显的改善作用。

Background and aims
There is an urgent need for valid assessment tools to assess physical activity (PA) levels in adolescents with autism. This study examines the concurrent validity of the Physical Activity Vital Sign (PAVS) and Online Physical Activity Logbook (OPAL) with accelerometry in adolescents with autism. A secondary aim was to explore the association and agreement between self-perceived and objectively measured PA intensity levels.
Methods
Forty-five adolescents with autism (71% males, Mdn = 14.0 (IQR = 13.0–15.5) years) completed the PAVS and OPAL and wore a wGT3X-BT ActiGraph accelerometer twice for seven consecutive days. Concurrent validity was assessed with Spearman correlations (ρ) and Wilcoxon Signed Rank/Paired Sample T-tests.
Results
A poor association was found between the PAVS and accelerometry (ρ = .37). The PAVS overestimated moderate-to-vigorous PA (MVPA) levels [Mdn = 152.1 min (IQR = 76.8–283.9), p < .001]. Poor associations (ρ = −.06 up to −.45) were observed between the OPAL and accelerometry for time spent in sedentary behavior (SB), light PA (LPA), moderate PA (MPA), vigorous PA (VPA) and MVPA. No significant mean and median differences were found for SB and VPA between the two methods respectively. A moderate association was found between self-perceived (OPAL) and objectively measured (accelerometry) VPA (ρ = .60) and MVPA (ρ = .51), while those for LPA and MPA were poor (ρ < .50). No significant median differences were found between self-perceived and objectively measured VPA.
Conclusion
Clinicians and researchers should be very cautious in using the PAVS to assess MVPA levels in adolescents with autism, while the utility of the OPAL, in its current form, is questionable. Adolescents with autism may estimate PA at a vigorous intensity accurately. Future research should further focus on examining the psychometric properties of self-report PA instruments, as well as the ability of adolescents with autism to accurately estimate the intensity of performed PA's.

Background
Cardiorespiratory fitness (CRF) refers to the capacity of the cardiovascular and respiratory system to process oxygen. CRF is associated with depressive symptoms and findings suggest that CRF decreased significantly in older adults during the COVID-19 pandemic. However, purchase of prescribed antidepressants before and after the pandemic lockdown by CRF level in older adults has not yet been described.
Methods
This longitudinal study included 1221 community-dwelling older adults ≥70 years old participating in the Norwegian HUNT4 Trondheim 70+ study (2018–2019). Data on estimated CRF (eCRF) were linked to the Norwegian Prescribed Drug Registry and utilized defined daily doses (DDDs) of antidepressants from January 2019 throughout December 2021. Paired t-tests were performed to assess changes in DDDs before and after the Norwegian COVID-19 lockdown in March 2020.
Results
Participants had a mean (M) and standard deviation (SD) age of 76.5 (5.2) years, 53.6% were women. In the total sample, the results showed a significant rise in purchase of antidepressants from before (M = 1.25, SD = 7.17) compared to after the lockdown (M = 1.52, SD = 7.86); t (1220) = −2.47, p = 0.014). The number of participants purchasing antidepressants also increased in the total sample and within each of the eCRF groups. In the different eCRF groups, only individuals in the highest eCRF tertile showed a significant higher purchase of antidepressants after the lockdown (M = 1.44, SD = 6.65); t (413) = −2.63, p = 0.009) compared to the year before (M = 0.99, SD = 5.21).
Conclusions
Compared to before the COVID-19 pandemic lockdown, the utilization of antidepressants increased in community-dwelling older adults, with the steepest increase observed among those with the highest eCRF levels.

Background and aims
While there is increasing evidence for the short-term effectiveness of exercise interventions for adults with anxiety disorders, follow-up studies are rare. The aim of this study was to examine whether the significant reductions in anxiety and depression symptoms observed in connection with our primary care-based 12-week exercise RCT were maintained at subsequent follow-up after nine-months. A further aim was to investigate the hypothesis whether exercise interacted with antidepressant medication.
Methods
113 out of 153 who completed the 12-week intervention completed the follow-up assessments. Symptoms were self-assessed with the Beck Anxiety Index (BAI) and the Montgomery Åsberg Depression Rating Scale (MADRS-S) at baseline, intervention completion (the 12-weeks follow-up) and 9 months post-intervention (the 1-year follow up).
Results
The reduced symptoms of anxiety and depression effects seen after 12 weeks in the intervention groups were maintained at the 1-year follow-up. Similar reductions were seen in the control group. However, among antidepressant users, the odds ratios for the intervention group to reach improvement in anxiety were four-fold, and in depression, eleven-fold compared to controls at the 1-year follow-up.
Conclusion
The results strengthen the view that physical exercise is an effective treatment for anxiety especially in among those with antidepressant treatment.
