Analysis of the aging-induced changes in the motor ability structure using large population fitness test results
Figure 2. Linear regression of records in four fitness tests on age. (A–D) show the linear regression and the corresponding goodness of fit of the records in grip strength, 50-meters dash speed, sit-ups, and PACER on age, respectively. The R2 value of the linear regression of grip strength on age is lower than those of other measures by one order of magnitude.
