Maximal exercise test is a useful method for physical capacity and oxygen consumption determination in streptozotocin-diabetic rats

Table 1 Relationships between measured VO₂ and VO₂ reserve with predicted VO₂ and VO₂ reserve.

	Variables	Mean ± SEM (ml/Kg/min)	r Value	r² Value	p Value (Pearson correlation)	SEE
CG	VO ₂ max measured	81.1 ± 1	0.81	0.66	0.0077	9.7
	VO ₂ max predicted	89.5 ± 4
	VO ₂ res max measured	51.2 ± 1	0.83	0.69	0.0053	9.4
	VO ₂ res max predicted	56.0 ± 5
DG	VO ₂ max measured	72.5 ± 1*	0.75	0.56	0.0314	7.7
	VO ₂ max predicted	74.6 ± 3*
	VO ₂ res max measured	34.4 ± 2*	0.75	0.57	0.0289	7.7
	VO ₂ res max predicted	32.2 ± 3*

Data are reported as mean ± SEM. r and r² values, standard error estimate – SEE and p values of Pearson correlation are presented; VO₂ max: maximal oxygen consumption; VO₂ res max: reserve maximal oxygen consumption; CG: control group; DG: diabetic group; * p < 0.05 vs. CG (one-way ANOVA).
