Within this literature, several studies have documented a distal effect of attentional focus by comparing the efficacy of a proximal and distal external focus. A potential confound is that most distal focus cues direct the performer's attention to an outcome occurring after the completion of movement, while the proximal cues direct attention to something that occurs during the movement process. This study aims to disentangle whether the distal effect of attentional focus comes from spatial distance (proximal vs. distal) or temporal distance (during vs. after). <b>Method:</b> To test this, we employed a two-handed underhand medicine ball throw for maximum distance with 38 healthy young adults.

However, the feasibility of using open goals over a longer duration remains unclear. Therefore, in this study, we examined the feasibility of using open goals in a 10-week step-based physical activity program. A single-arm mixed methods design was used, involving 15 healthy adults (13 female; M<sub>age</sub> = 42.53) with low to moderate physical activity levels.

The feasibility domains assessed included recruitment, acceptability, adherence, and retention. Quantitative methods assessed physical activity, enjoyment, and self-efficacy, while supplementary qualitative methods explored participants' perceptions of open goals. The study showed high recruitment and retention rates, increased physical activity, and positive psychological experiences, indicating the feasibility of the 10-week open-goal program. Secondary outcomes suggest that open goals may function by increasing enjoyment and self-efficacy while decreasing negative outcomes such as pressure, guilt, and failure.

Randomized clinical trial with early postmenopausal women divided into two groups: Jazz Dance Intervention Group (GIDJ) (<i>n</i> = 23), and control group (CG) (<i>n</i> = 24). The physical exercise group received interventions of two weekly sessions of 60 minutes each, for 16 weeks. The control group received monthly calls, educational lectures, and maintained their usual activities during the intervention period. Assessments with all participants occurred at baseline, after the 1st month, after the interventions, and at the six-month follow-up. The evaluations are assessed by questionnaires and include menopausal symptoms (Menopause Rating Scale), depressive and anxiety symptoms (Anxiety and Depression Scale), stress (Perceived Stress Scale), mood (Brunel Mood Scale), and aging perspective (Sheppard Inventory). There was a significant improvement in GIDJ outcomes post-intervention, such as menopausal symptoms (<i>p</i> = .001), psychological aspects (anxiety (<i>p</i> =  <.001), depression (<i>p</i> = .016) and stress (<i>p</i> = .030)); in the integrity domain (<i>p</i> = .011) for the aging perspective, and in the confusion (<i>p</i> = .028) and vigor (<i>p</i> = .044) domains for mood. Furthermore, the CG showed significant improvements in the happiness domain at one month of intervention (<i>p</i> = .043) from the perspective of aging. Jazz Dance is effective in treating symptoms of menopause, depression, anxiety and stress, especially with an intervention of at least 16 weeks duration.</p>","PeriodicalId":94191,"journal":{"name":"Research quarterly for exercise and sport","volume":" ","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142335474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
