Table 5.
The suggested regression equations and cut points obtained for two subgroups of differing age; group 1: age 24–42 (35.7 ± 5.7) years, n = 20; group 2: age 43–62 (50.0 ± 5.5) years, n = 22. β: regression coefficient; CI: confidence interval; SEE: standard error of the estimate; MPA: moderate physical activity; VPA: vigorous physical activity.
