However, many existing fitness and health evaluation methods rely on resource-intensive measurements, limiting their applicability in large-scale or under-resourced settings. The standing long jump (SLJ), a simple field-based test of lower-limb explosive power, may serve as a practical and scalable indicator of physical fitness among male college students.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This cross-sectional study included 7,842 male college students. SLJ performance was assessed alongside key health-related fitness indicators, including cardiorespiratory fitness (1000-m run), muscular endurance (pull-ups), flexibility (sit-and-reach), and body composition (BMI). Pearson correlation analysis was conducted to examine associations between SLJ and these variables.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      SLJ performance was significantly associated with all measured variables (\n                      <jats:italic>p<\/jats:italic>\n                      &amp;lt;\u202f0.01). It was negatively correlated with 1,000-m run time and BMI, suggesting associations with better cardiorespiratory fitness performance and lower BMI within this male college student sample. Positive correlations were observed between SLJ and both pull-up performance and flexibility. These findings indicate that SLJ is associated with multiple dimensions of physical fitness in young adult men.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>As a low-cost, scalable, and easily implementable measure, SLJ has potential utility for large-scale fitness assessment among male college students. Its associations with multiple domains of physical fitness support its use as an accessible field-based assessment tool in university or resource-limited settings. Given that the present study included only male college students, the findings should not be generalized to female students, other age groups, or non-college populations without further validation. These findings contribute to the development of accessible and data-efficient strategies for context-specific health and fitness assessment.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpsyg.2026.1856443","type":"journal-article","created":{"date-parts":[[2026,7,9]],"date-time":"2026-07-09T04:23:23Z","timestamp":1783571003000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["SLJ is associated with multiple field-based fitness indicators in young adult males"],"prefix":"10.3389","volume":"17","author":[{"given":"Chao-Fu","family":"Chen","sequence":"first","affiliation":[{"name":"Physical Education College, Jimei University","place":["Xiamen, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui-Ju","family":"Wu","sequence":"additional","affiliation":[{"name":"Xiamen Yixue Sports and Technology Co., Ltd.","place":["Xiamen, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan-Zhi","family":"He","sequence":"additional","affiliation":[{"name":"Physical Education College, Jimei University","place":["Xiamen, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian-Fu","family":"Cheng","sequence":"additional","affiliation":[{"name":"Physical Education College, Jimei University","place":["Xiamen, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bo-Jun","family":"Zhou","sequence":"additional","affiliation":[{"name":"Physical Education College, Jimei University","place":["Xiamen, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian-Ming","family":"Wu","sequence":"additional","affiliation":[{"name":"Physical Education College, Jimei University","place":["Xiamen, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qi-Fan","family":"Zheng","sequence":"additional","affiliation":[{"name":"Physical Education College, Jimei University","place":["Xiamen, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin-Rui","family":"Wang","sequence":"additional","affiliation":[{"name":"Physical Education College, Jimei University","place":["Xiamen, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teng-Xiang","family":"Ge","sequence":"additional","affiliation":[{"name":"Physical Education Department, Xiangtan University","place":["Xiangtan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Lin-Zhu","sequence":"additional","affiliation":[{"name":"Physical Education College, Zhengzhou University of Industrial Technology","place":["Zhengzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian-Hua","family":"Pan","sequence":"additional","affiliation":[{"name":"College of Physical Education, Chongqing University","place":["Chongqing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,7,9]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"3","DOI":"10.1016\/j.smhs.2019.08.006","article-title":"Physical activity, exercise, and chronic diseases: a brief review","volume":"1","author":"Anderson","year":"2019","journal-title":"Sports Med.
