The participants performed three trials of handgrip strength measurement for each hand alternately, with 60\u2010s rest between the trials. From this pool of data, we included 23\u2009901 participants aged \u226519\u2009years who had completed surveys on the handgrip strength test, and obtained their medical history.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The dominant hand had a significantly stronger handgrip strength than the non\u2010dominant hand (32.75\u2009\u00b1\u20090.10 vs. 30.95\u2009\u00b1\u20090.09\u2009kg, <jats:italic>P<\/jats:italic> &lt;\u20090.001); however, 26.4% of the subjects had stronger handgrip strength in the non\u2010dominant hand. During the three repeated measurements, the handgrip strength gradually increased; however, the mean difference between the trials (0.579 and 0.104\u2009kg) was below the noninferiority threshold. In older adults, however, the mean difference in the handgrip strength between the first and the second trial was higher than the noninferiority threshold.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>While the handgrip strength gradually increased during three repeated measurements, the difference was clinically important only in older adults. Hence, we suggest that the handgrip strength should be measured in both hands and at least twice in older adults, whereas a single attempt provides a maximal value in younger adults. <jats:bold>Geriatr Gerontol Int 2021;
