The Effect of Long-Term Exercise on the Production of Osteoclastogenic and Antiosteoclastogenic Cytokines by Peripheral Blood Mononuclear Cells and on Serum Markers of Bone Metabolism

Figure 7

Scattergram showing the effects of the exercise training program on serum levels of osteocalcin and CTXI. Osteocalcin levels increased by 9.8 percent () and CTXI levels fell by 16% (). Preexercise values are depicted by white circles and postexercise values by black circles. Osteocalcin levels are shown on the left Y axis and CTXI levels on the right Y axis. Error bars show the mean ± (SEM) (2-sided t-test for dependent samples).
