Data for this study were obtained from the National Fitness Center operated by the Korea Institute of Sport Science (n = 429 572). The following were excluded from this study: women aged 44 years or younger (n = 238 257), repeated measurement data (n = 130 466), and errors or missing data (n = 6 497). The final sample included 54 352 participants (27 878 middle-aged and 26 474 older-aged). The highest overall physical fitness grade among participants was 5.6% (4.7%, middle-aged men; 6.6%, older men), the lowest was 52.1% (59.0%, middle-aged men, 43.9%, older men). HGS was positively correlated with flexibility (r = 0.183), muscular endurance (r = 0.354), and power (r = 0.463), in middle-aged men. In older men, flexibility (r = 0.227), and 30SCS (r = 0.385), were positively correlated; Timed Up and Go (r = \u22120.405), and F8W (r = \u22120.433), were negatively correlated. All physical fitness parameters were significantly higher in participants with normal HGS than those with low HGS. Our finding suggests that HGS is a predictive method for physical fitness variables and a useful biomarker for global public health.<\/jats:p>","DOI":"10.1177\/10105395241275223","type":"journal-article","created":{"date-parts":[[2024,8,30]],"date-time":"2024-08-30T05:51:41Z","timestamp":1724997101000},"page":"689-695","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Association
