Five databases were included. The study analyzed 16 randomized controlled trials. Subsequent analysis was performed for moderators variables as age, skill, retention, stress situations number of rules, specificity and number of trials. The ANA instruction demonstrated greater efficacy than the control (ES = 0.32, p = 0.03) or EXP condition (ES = 0.29, p = 0.02) in motor tasks performance in general terms. ANA instructions also showed superiority in motor performance when compared to control conditions in retention (ES = 5.72, p = 0.004), and a trend towards significance was found under stress (ES = 1.18, p = 0.05). ANA also showed superiority in motor performance when compared to EXP instruction (ES = 0.29, p = 0.02). ANA demonstrated greater effects than EXP in retention (ES = 7.25, p = 0.01), but not under stress (ES = 0.62, p = 0.18). Sub-analyses demonstrated that children (all p &lt; 0.01) and novices (all p &lt; 0.01) are more likely to benefit from ANA instruction when compared to control or EXP. A subgroup analysis based on quantity of information comparing ANA versus EXP condition shows that ANA is more effective for enhancing motor performance than EXP when the number of rules are similar. Sub-analyses comparing ANA versus CNT shows that as the number of repetitions increases and the task becomes less specific, ANA instruction significantly improves performance. A comparison between ANA and EXP indicates no significant differences in performance regarding the number of repetitions and task specificity. A secondary analysis examined KD of different instructions. KD was greater in EXP instructions (ES = −1.48, p &lt; 0.001) when compared to ANA. Findings suggest that analogy instruction may improve motor performance, especially in novice and child populations. However, caution is needed due to concerns when comparing with other instructional types and environments, as well as due to high heterogeneity in most of the comparisons and high risk of bias in included studies.</div></div>","PeriodicalId":54536,"journal":{"name":"Psychology of Sport and Exercise","volume":"76 ","pages":"Article 102766"},"PeriodicalIF":3.1,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142484631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study investigated trait differences between competitive and recreational runners at sub-ultra and ultramarathon distances. Six hundred and eleven participants (334 recreational, 400 sub-ultrarunner) completed an online, anonymous survey assessing five traits: mental toughness (MT), grit, motivation, general self-efficacy (GSE), and personality. Bayesian ANOVAs indicated at least moderate evidence for differences within Distance for grit-perseverance of effort (PE) and intrinsic motivation (IM), such that ultrarunners scored higher than sub-ultrarunners. Similarly, we observed at least moderate evidence that competitive runners scored higher than recreational runners on overall grit, grit-PE, GSE, IM, and extrinsic motivation (EM). Interaction effects provided moderate evidence for greater MT and overall grit in competitive ultrarunners. Evidence for other differences were anecdotal or favoured the null hypothesis. This study represents a novel investigation into the psychological makeup of runners. We suggest that aspects of motivation, grit, and self-efficacy, but not personality, may differentiate competitive from recreational runners, and ultrarunners from sub-ultrarunners. The identification of these trait differences may benefit runners and coaches wanting to progress in distance or competition level, with broader application to workplace or academic contexts. Further research is needed to develop a clearer conceptualisation of mental toughness, and build upon the novel findings of this study, particularly given the paucity of literature that exists within this context.</div></div>","PeriodicalId":54536,"journal":{"name":"Psychology of Sport and Exercise","volume":"76 ","pages":"Article 102765"},"PeriodicalIF":3.1,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142484633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
