The aim was to analyze the relationship between motor competence (MC) and PA and the role of physical fitness (PF). Participants were<jats:italic>N<\/jats:italic>\u2009=\u20091,064 children of both sexes (<jats:italic>n<\/jats:italic>\u2009=\u2009530 girls) and 7.87\u2009\u00b1\u20091.17\u00a0years of age. MC was assessed with K\u00f6rperkoordinationTest f\u00fcr Kinder. PF was assessed with 50-yard dash, 1-mile run\/walk, and standing long jump. PA was assessed with a questionnaire. Mediation and moderation were determined according to Baron and Kenny using Sobel test for indirect effect and using PROCESS (version 3.4). Mediation results showed perfect mediation in girls but not in boys and not when all participants were included in the analysis. The linear moderation was significant for all participants and for boys and girls apart. However, the results of conditional effects of MC at the 16th, 50th, and 84th percentile of the PF, which became significant at the 50th percentile for all participants and for boys, were not significant in girls. In conclusion, perfect mediation seems to exist in girls but not in boys. In boys, the relationship between MC and PA seems conditioned by the PF levels.<\/jats:p>","DOI":"10.1123\/jmld.2020-0070","type":"journal-article","created":{"date-parts":[[2021,9,22]],"date-time":"2021-09-22T15:13:49Z","timestamp":1632323629000},"page":"456-469","source":"Crossref","is-referenced-by-count":11,"title":["The Role of Physical Fitness on the Relationship Between Motor Competence and Physical Activity: Mediator or Moderator?"],"prefix":"10.1123","volume":"9","author":[{"given":"Vitor P.","family":"Lopes","sequence":"first","affiliation":[{"name":"1Research Center in Sports Sciences, Health Sciences and Human Development (CIDESD), Instituto Polit\u00e9cnico de Bragan\u00e7a, Bragan\u00e7a, Portugal"}]},{"given":"Luis P.","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"2Research Center in Sports Sciences, Health Sciences and Human Development (CIDESD), Escola Superior Desporto e Lazer de Melga\u00e7o, Instituto Polit\u00e9cnico de Viana do Castelo, Viana do Castelo, Portugal"}]}],"member":"100","reference":[{"key":"ref251","doi-asserted-by":"crossref","first-page":"717","DOI":"10.3758\/BF03206553","article-title":"SPSS and SAS procedures for estimating indirect effects in simple mediation models","volume":"36","author":"Preacher","year":"2004","journal-title":"Behavior Research Methods, Instruments, & Computers,"},{"key":"ref141","volume-title":"Korperkoordinationstest fur kinder [Body cooordination test for children]","author":"Kiphard","year":"1974"},{"key":"ref91","first-page":"141","article-title":"A simple method to assess exercise behavior in the community","volume":"10","author":"Godin","year":"1985","journal-title":"Canadian Journal of Applied Sport Sciences,"},{"key":"ref121","doi-asserted-by":"crossref","first-page":"331","DOI":"10.1080\/00461520.2016.1207175","article-title":"The merits of using longitudinal mediation","volume":"51","author":"Jose","year":"2016","journal-title":"Educational Psychologist,"},{"key":"ref11","doi-asserted-by":"crossref","first-page":"33","DOI":"10.1123\/APAQ.2014-0228","article-title":"Convergent and divergent validity between the KTK and MOT 4-6 motor tests in early childhood","volume":"33","author":"Bardid","year":"2016","journal-title":"Adapted Physical Activity Quarterly,"},{"key":"ref321","doi-asserted-by":"crossref","first-page":"290","DOI":"10.1080\/00336297.2008.10483582","article-title":"A developmental perspective on the role of motor skill competence in physical activity: An emergent relationship","volume":"60,","author":"Stodden","year":"2008","journal-title":"Quest,"},{"key":"ref461","first-page":"141","article-title":"A simple method to assess exercise behavior in the community","volume":"10","author":"Godin","year":"1985","journal-title":"Canadian Journal of Applied Sport Sciences,"},{"key":"ref31","doi-asserted-by":"crossref","first-page":"1173","DOI":"10.1037\/0022-3514.51.6.1173","article-title":"The moderator-mediator variable distinction in social psychological research: Conceptual, strategic, and statistical considerations","volume":"51","author":"Baron","year":"1986","journal-title":"Journal of Personality and Social Psychology,"},{"key":"ref631","doi-asserted-by":"crossref","first-page":"1273","DOI":"10.1007\/s40279-015-0351-6","article-title":"Motor competence and its effect on positive developmental trajectories of health","volume":"45","author":"Robinson","year":"2015","journal-title":"Sports Medicine,"},{"key":"ref411","doi-asserted-by":"crossref","first-page":"746","DOI":"10.1249\/MSS.0000000000001147","article-title":"Gross motor skills and cardiometabolic risk in children: A mediation analysis","volume":"49","author":"Burns","year":"2017","journal-title":"Medicine & Science in Sports & Exercise,"},{"key":"ref661","doi-asserted-by":"crossref","DOI":"10.2378\/mot2014.art29d","article-title":"K\u00f6rperkontrolle und kindliche Entwicklung.
