Methods: The research involved 64 participants divided into sedentary and physically active groups based on metabolic equivalents of task (METs) values, normal weight, overweight, and obese according to body composition. Postural control was evaluated using the Sensory Organization Test. Results: The results showed that there were no significant differences in mean and maximum lower limb strength between the groups. Furthermore, postural stability in open and closed eyes conditions did not show significant differences between the groups. However, a significant positive correlation was observed between lower limb strength and stability in single-leg stance with eyes open. Conclusions: These findings suggest that lower limb muscle strength is essential for postural stability, especially when vision is available to aid balance. The study highlights the importance of interventions focused on strengthening muscles to improve physical functionality in adults.<\/jats:p>","DOI":"10.3390\/jfmk9040282","type":"journal-article","created":{"date-parts":[[2024,12,23]],"date-time":"2024-12-23T05:58:27Z","timestamp":1734933507000},"page":"282","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Single-Leg Balance and Lower Limb Strength: Quantitative Analysis with the Balance Master System"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6660-7943","authenticated-orcid":false,"given":"Jos\u00e9 Manuel","family":"Delfa-de-la-Morena","sequence":"first","affiliation":[{"name":"Department of Physical Therapy, Occupational Therapy, Rehabilitation and Physical Medicine, Health Sciences Faculty, Rey Juan Carlos University, 28922 Madrid, Spain"},{"name":"Cognitive Neuroscience, Pain, and Rehabilitation Research Group (NECODOR), Faculty of Health Sciences, Rey Juan Carlos University, 28922 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6765-5672","authenticated-orcid":false,"given":"Pedro Pinheiro","family":"Paes","sequence":"additional","affiliation":[{"name":"Department of Physical Education, Federal University of Pernambuco, Recife 50670-901, Brazil"},{"name":"Research and Studies in Health and Performance Group (GEPPHS), Federal University of Pernambuco, Recife 50670-901, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6096-3317","authenticated-orcid":false,"given":"D\u00e9bora Priscila Lima","family":"de Oliveira","sequence":"additional","affiliation":[{"name":"Department of Physical Education, Federal University of Pernambuco, Recife 50670-901, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8215-6903","authenticated-orcid":false,"given":"Frederico Camarotti","family":"J\u00fanior","sequence":"additional","affiliation":[{"name":"Department of Physical Education, Federal University of Pernambuco, Recife 50670-901, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bruna Daniele Monteiro","family":"Lima","sequence":"additional","affiliation":[{"name":"Department of Physical Education, Federal University of Pernambuco, Recife 50670-901, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-2195-8459","authenticated-orcid":false,"given":"Miriam","family":"Garc\u00eda-Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Occupational Therapy, Rehabilitation and Physical Medicine, Health Sciences Faculty, Rey Juan Carlos University, 28922 Madrid, Spain"},{"name":"International Doctoral School, Faculty of Health Sciences, Rey Juan Carlos University, 28922 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-2225-5253","authenticated-orcid":false,"given":"Juan-Jos\u00e9","family":"Mijarra-Murillo","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Occupational Therapy, Rehabilitation and Physical Medicine, Health Sciences Faculty, Rey Juan Carlos University, 28922 Madrid, Spain"},{"name":"International Doctoral School, Faculty of Health Sciences, Rey Juan Carlos University, 28922 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3914-7355","authenticated-orcid":false,"given":"V\u00edctor","family":"Riquelme-Aguado","sequence":"additional","affiliation":[{"name":"Department of Basic Health Sciences, Health Sciences Faculty, Rey Juan Carlos University, 28922 Madrid, Spain"},{"name":"Research Group on Anatomical, Molecular and Human Development Bases (GAMDES), Rey Juan Carlos University, 28922 Madrid, Spain"},{"name":"Fisioterapia Oreka CB, 45200 Illescas, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Onofrei, R.R., and Amaricai, E.
