Exercise and ovarian steroid hormones: Their effects on mitochondrial respiration

The effect of exercise on mitochondria respiration was studied in gastrocnemius muscle of ovariectomized rats, pseudopregnant rats, and estrous rats. The estrous cycles were followed by vaginal smears. Rats were made pseudopregnant (PSP) by 45 s cervical stimulation with a glass rod on the day of es...

The estrous cycles were followed by vaginal smears. Rats were made pseudopregnant (PSP) by 45 s cervical stimulation with a glass rod on the day of estrous. The treadmill protocol (21 m/min, 10 grade uphill) induced a significant decrease in state 3 oxygen consumption (oxidative phosphorylation) in estrous (0.26 ± 0.02 vs. 0.49 ± 0.05 μatoms O min-1 mg protein-1) and ovariectomized rats (0.18 ± 0.03 vs. 0.40 ± 0.03 μatoms O min-1 mg protein-1). In contrast, pseudopregnant and progesterone-treated ovariectomized rats did not decrease state 3 nor state 4 respiratory rates. These results show that the effect of exercise on mitochondria respiration does vary according to the hormonal status. © 2001 Elsevier Science Inc.
