The Oxidant–Antioxidant Equilibrium and Inflammatory Process Indicators after an Exercise Test on the AlterG Antigravity Treadmill in Young Amateur Female Athletes

Table 2

The levels of primary and secondary lipid peroxidation products, concentration of low molecular weight antioxidants, activities of antioxidant and lysosomal enzymes, and level of serine protease inhibitor in the peripheral blood of young amateur female volleyball players, as a result of a 30-min running test on the AlterG antigravity and classic treadmills.
