Table 2.

Assessment of sex, anaerobic exercise, and sex–anaerobic exercise interaction influence on antioxidant enzyme activity in the blood plasma based on the results of two-way analysis of variance with repeated measures.

Variable	Sex	Anaerobic exercise	Sex–anaerobic exercise interaction
		p-value (F)
SOD	0.10 (2.93)	0.01 (3.36)	0.59 (0.75)
CAT	0.07 (3.61)	0.03 (2.62)	0.92 (0.28)
GPx	0.17 (2.07)	<0.01 (6.60)	0.59 (0.75)

SOD, superoxide dismutase; CAT, catalase; GPx, glutathione peroxidase; statistical power (1-β) and size effect (η²) to assess the effect of anaerobic exercise on the activity of antioxidant enzymes at p = 0.05 were, respectively, 0.89 and 0.16 for SOD, 0.78 and 0.13 for CAT, and 0.99 and 0.27 for GPx.
