A total of 126 participants (66 males, 60 females) performed single-leg landing tasks, during which ground reaction forces (GRF) and center of pressure (COP) data were collected using a Kistler 3D force platform and Bioware acquisition system. Dynamic stability times in the anterior\u2013posterior, medial\u2013lateral, and vertical directions were calculated with polynomial fitting, and additional time-domain measures were used to assess static and dynamic stability. Results showed that on the non-dominant side, participants exhibited significantly longer dynamic stability times (p = 0.015), greater root mean square distance (p = 0.005), and longer total sway path (p = 0.005) in the anterior\u2013posterior direction compared with the dominant side. Significant sex differences were also found in vertical stability index (p = 0.044), dynamic stability index (p = 0.047), total sway path (p &lt; 0.001), anterior\u2013posterior sway path (p = 0.001), and medial\u2013lateral sway path (p &lt; 0.001). In conclusion, the dominant limb demonstrated superior stability, males showed better static control, and females displayed greater dynamic stability, underscoring the importance of targeted non-dominant training and sex-specific balance strategies.<\/jats:p>","DOI":"10.3390\/sym17101734","type":"journal-article","created":{"date-parts":[[2025,10,15]],"date-time":"2025-10-15T06:06:32Z","timestamp":1760508392000},"page":"1734","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Sex and Limb Dominance Differences in Postural Control Performance of Young Adults: A Third-Order Polynomial Decay Approach"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-1442-1075","authenticated-orcid":false,"given":"Yang","family":"Sun","sequence":"first","affiliation":[{"name":"School of Physical Education, Yanshan University, Qinhuangdao 066004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hanbing","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Physical Education, Yanshan University, Qinhuangdao 066004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xingchen","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Physical Education, Yanshan University, Qinhuangdao 066004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiujiang","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Physical Education, Yanshan University, Qinhuangdao 066004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guanying","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Physical Education, Yanshan University, Qinhuangdao 066004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9149-539X","authenticated-orcid":false,"given":"Lian","family":"Duan","sequence":"additional","affiliation":[{"name":"School of Physical Education, Yanshan University, Qinhuangdao 066004, China"},{"name":"China Volleyball College, Beijing Sport University, Beijing 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuan","family":"Gao","sequence":"additional","affiliation":[{"name":"School of Physical Education, Yanshan University, Qinhuangdao 066004, China"},{"name":"Hebei Provincial Key Laboratory of Intelligent Rehabilitation and Neuromodulation, Yanshan University, Qinhuangdao 066004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"35","DOI":"10.1007\/s00221-005-0224-6","article-title":"A Direct Comparison of Local Dynamic Stability During Unperturbed Standing and Walking","volume":"172","author":"Kang","year":"2006","journal-title":"Exp.
