The aim of this study was to compare active women with inactive women of different age groups regarding muscle mass, strength, and muscle quality. Methods: This study included 147 women (85 runners and 62 inactive), divided into &lt;50 and \u226550 years old. Participants were evaluated for knee flexor and extensor peak torque (PT), body composition, and training habits. Results: For knee extensor muscles, there was an age group effect (F(2.146) = 40.5; p &lt; 0.001) on absolute PT (Nm); an age group effect (F(2.146) = 44.1; p &lt; 0.001) and a physical activity group effect (F(2.146) = 113.0; p &lt; 0.001) on PT adjusted by body mass (Nm\/kg); and an age group effect (F(2.146) = 36.9; p &lt; 0.001) and a physical activity group effect (F(2.146) = 6.1; p = 0.014) on PT adjusted by lean mass (Nm\/kgLM). There was no interaction effect. Conclusion: In both age groups, active women had greater strength and higher muscle quality than inactive women, but the difference in strength, muscle mass, and muscle quality between younger and older women were the same among runners and inactive women.<\/jats:p>","DOI":"10.3390\/geriatrics9050127","type":"journal-article","created":{"date-parts":[[2024,10,4]],"date-time":"2024-10-04T03:26:36Z","timestamp":1728012396000},"page":"127","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Running Plus Strength Training Positively Affects Muscle Strength and Quality in Both Younger (Below 50 Years Old) and Older (Above 50 Years Old) Women"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4338-2796","authenticated-orcid":false,"given":"Lav\u00ednia","family":"Vivan","sequence":"first","affiliation":[{"name":"Postgraduate Program in Translation Medicine, Federal University of S\u00e3o Paulo, S\u00e3o Paulo 04023-062, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4214-8981","authenticated-orcid":false,"given":"Vin\u00edcius Ribeiro","family":"dos Anjos Souza","sequence":"additional","affiliation":[{"name":"Postgraduate Program in Translation Medicine, Federal University of S\u00e3o Paulo, S\u00e3o Paulo 04023-062, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8229-8565","authenticated-orcid":false,"given":"Aldo","family":"Seffrin","sequence":"additional","affiliation":[{"name":"Postgraduate Program in Translation Medicine, Federal University of S\u00e3o Paulo, S\u00e3o Paulo 04023-062, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5749-6877","authenticated-orcid":false,"given":"Claudio Andre Barbosa","family":"de Lira","sequence":"additional","affiliation":[{"name":"Human and Exercise Physiology Division, Faculty of Physical Education and Dance, Federal University of Goi\u00e1s, Goi\u00e1s 74690-900, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1981-1092","authenticated-orcid":false,"given":"Rodrigo Luiz","family":"Vancini","sequence":"additional","affiliation":[{"name":"Center for Physical Education and Sports, Federal University of Esp\u00edrito Santo, Esp\u00edrito Santo 29075-810, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1247-6754","authenticated-orcid":false,"given":"Katja","family":"Weiss","sequence":"additional","affiliation":[{"name":"Institute of Primary Care, University of Zurich, CH-8006 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2412-9103","authenticated-orcid":false,"given":"Beat","family":"Knechtle","sequence":"additional","affiliation":[{"name":"Institute of Primary Care, University of Zurich, CH-8006 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7004-4565","authenticated-orcid":false,"given":"Marilia Santos","family":"Andrade","sequence":"additional","affiliation":[{"name":"Department of Physiology, Federal University of S\u00e3o Paulo, S\u00e3o Paulo 04023-062, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2636","DOI":"10.1016\/S0140-6736(19)31138-9","article-title":"Sarcopenia","volume":"393","author":"Sayer","year":"2019","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"299","DOI":"10.1016\/j.clnesp.2021.07.031","article-title":"Sarcopenia and Poor Muscle Quality Associated with Severe Obesity in Young Adults and Middle-Aged Adults","volume":"45","author":"Mulder","year":"2021","journal-title":"Clin.
