Nonetheless, the impact of visuospatial working memory capacity (WMC) in this context, especially among children, has been less investigated. This research sought to examine the effects of EF compared to IF on the skill acquisition and motor learning of a dart-throwing task among children with both high and low visuospatial WMC. Forty-eight boys aged 9–11 (Mage: 9.67 ± 0.76 years) were grouped by high or low WMC based on spatial span and memory tests, then assigned to receive either EF or IF instructions. The experiment comprised three stages: practice, retention, and two transfer tests, including throwing from a longer distance and a dual-task scenario with added cognitive load (tone counting). Results showed that EF outperformed IF at all stages. While WMC did not affect performance during practice and retention, children with low WMC performed better than those with high WMC during the longer distance test. In dual-task conditions, an EF continued to surpass an IF, whilst the WMC exerted no significant impact.

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":"2025-02-01","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}
