r 2 = linear regression coefficient.
General group: body mass associated with BMI explained 66% of the stability index for overall balance, and body mass explained 59% of the anteroposterior stability index and 65% of the mediolateral stability index.
Male group: body mass associated with height explained 51% of the overall balance, body mass explained 37% of the anteroposterior stability index, and body mass associated with height explained 52% of the mediolateral stability index.
Female group: body mass explained 72% of the overall balance, 66% of the anteroposterior stability index, and 76% of the mediolateral stability index.
