Correction: Associations between physical activity, physical fitness, and body composition in adults living in Germany: A cross-sectional study

In the Physical fitness subsection of the Materials and methods, the equation shows an incorrect formula for calculating the Z-scores. Please view the complete, correct equation here:

$$\begin{array}{c}\hfill \text{Z}=\text{100}+\frac{\text{raw}\text{value}-\bar{\text{x}}}{\bar{\text{s}}}•\text{10}\end{array}$$

$\bar{\text{x}}$ = mean value of the 33-36-year-old men at the first time of measurement in 1992,

$\bar{\text{s}}$ = standard deviation of the 33-36-year-old men at the first time of measurement in 1992
