Fat-free mass and SES revealed small-to-moderate influences on the relationship between MVPA, standing broad jump (SBJ;\u00a0r\u00a0= 0.32), predicted VO2max (r\u00a0= 0.28) and beep levels (r\u00a0= 0.22). For MRPF, the quality of running (r\u00a0= 0.12) and balancing were associated with MVPA. Adjusting for sex, BC and SES in the relationship between PA with HRPF and MRPF, reductions in most correlations were observed.\n\nConclusion:\u00a0Moderate vigorous physical activity levels were positively associated with HRPF, MRPF and some motor skills in 5\u20138-year-olds. Socioeconomic status (lower parental income, employment and education negatively influenced the association between MVPA and fitness [beeps, SBJ,\u00a0O2max]).\n\nContribution:\u00a0This study provides knowledge with regard to the use of accelerometer for baseline data for PA, MRPF, HRPF as well as motor skills in South African children.<\/jats:p>","DOI":"10.4102\/phcfm.v16i1.4258","type":"journal-article","created":{"date-parts":[[2024,5,20]],"date-time":"2024-05-20T19:02:48Z","timestamp":1716231768000},"update-policy":"https:\/\/doi.org\/10.4102\/crossmark-policy","source":"Crossref","is-referenced-by-count":11,"title":["Relationships between moderate vigorous physical activity, motor- and health-related fitness and motor skills in children  Article DOI:"],"prefix":"10.4102","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1042-9367","authenticated-orcid":false,"given":"Carli","family":"Gericke","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/010f1sq29","id-type":"ROR","asserted-by":"publisher"}],"name":"North-West University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9487-5953","authenticated-orcid":false,"given":"Anita E.","family":"Pienaar","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/010f1sq29","id-type":"ROR","asserted-by":"publisher"}],"name":"North-West University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8006-8552","authenticated-orcid":false,"given":"Barry","family":"Gerber","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/010f1sq29","id-type":"ROR","asserted-by":"publisher"}],"name":"North-West University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4156-8394","authenticated-orcid":false,"given":"Makama A.","family":"Monyeki","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/010f1sq29","id-type":"ROR","asserted-by":"publisher"}],"name":"North-West University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2580","published-online":{"date-parts":[[2024,5,20]]},"reference":[{"key":"ref0","unstructured":"World Health Organization.
