Forty-four healthy women were randomized into three groups: MI, AO, or sham observation (SO) group. The outcome measures included the pelvic floor muscles (PFM) condition (including basal tone and strength), lumbo-pelvic motor control, and pain sensitivity. All women performed six sessions at the rate of 3 s/week (for 2 weeks). An initial assessment was carried out (T0), another one 1-week after starting the study (T1), and a third one at the end (T2). Results showed significant PFM strength gains in MI and AO groups, but not in the SO group. Regarding lumbo-pelvic motor control, both MI and AO groups obtained statistically significant changes between pre- and post-intervention Additionally, only the AO group showed significant improvements already at 1-week of intervention. Finally, all groups showed improved pain sensitivity in the likely area of referred menstrual pain post-intervention, with only the MI group showing changes 1 week after starting the intervention. In conclusion, results showed that adding MI and AO to PE program leads to an improvement of sensorimotor function of PFM and related structures in general. Despite finding no statistically significant inter-group differences, some findings such as strength gains or the lumbo-pelvic motor control improvements were only found in MI and AO groups, and this should be considered clinically.</div></div>","PeriodicalId":55046,"journal":{"name":"Human Movement Science","volume":"99 ","pages":"Article 103313"},"PeriodicalIF":1.6,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142759396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To build on this the current study investigated the roles of general and movement-specific anxiety, self-efficacy, general resilience and motor control in how 41 adults with typical motor skills thought they would behave (perceptual judgement) and how they actually behaved (executed action). Participants completed several standardised scales and two movement-specific scales, a perceptual judgement task and an executed action task. In the perceptual judgement task participants judged whether they would need to turn their shoulders to walk through different sized apertures between 0.9 and 1.9 their shoulder width-to-aperture ratio. This involved a static (standing still) and a dynamic (walking towards) condition. The executed action task involved actually walking through the different sized gaps between the doors. Findings were discussed within an ecological framework drawing strongly on Newell's constraints-based approach (1986). Results indicated a relationship between higher movement-specific anxiety and bigger safety margins. This highlights the importance of measure specificity in being able to detect nuanced relationships between affective factors and the perception-action cycle. Notable differences were also shown in the point of behaviour change (critical ratio) between perceptual judgement and executed action, illustrating the importance of studying perception and action together since they can be subject to different constraints. The findings contribute novel insights into the roles of these factors in how adults with typical motor skills perceive and realise their intentions and abilities to act in the world.</div></div>","PeriodicalId":55046,"journal":{"name":"Human Movement Science","volume":"98 ","pages":"Article 103306"},"PeriodicalIF":1.6,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142698822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forty-nine children (15 boys, 34 girls; mean age 10.61 ± 1.38 years) completed the Dragon Challenge (DC) dynamic movement assessment battery.
