@@中村たまき-n1y 原文を読むと、2m/s なので、秒速2メートルの早歩きですね(別の参考文献では、通常、人が歩く速度が1.25m/sだそうです) Additional accelerometry data collected under different exercise conditions in ten individuals (Supplementary Table 1) showed that ambulation at 2 m/s fell inside this 0.44 and 0.59 g MAD range. Walking at 1.5 m/s or slower fell below this range and running at 2.5 m/s or faster and jumping were above this range.
