Estrogen deficiency intensifies sarcopenia by activation of inflammatory and oxidative pathways. Aerobic exercise training and antioxidant/inflammatory supplements might reverse such outcomes or decline the degenerative pathway. Thus, we investigated the impact of aerobic training and crocin (CRO) consumption on skeletal muscle MuRf-1 and plasma antioxidant and inflammatory statues in ovariectomized (OVX) rat models fed on a high-fat diet (HFD). 72 female Wistar rats (200 ± 20 gr) were randomly divided into 9 groups: (1) non-OVX + standard chow (nOVX + SC), (2) nOVX + HFD, (3) high-intensity continuous training (HICT) + OVX + HFD + CRO, (4) HICT + OVX + HFD, (5) moderate-intensity continuous training (MICT) + OVX + HFD + CRO, (6) MICT + OVX + HFD, (7) OVX + HFD + CRO, (8) OVX + SC, and (9) OVX + HFD. The OVX rats underwent surgery for menopause model induction. Immediately after the ovariectomy, rats were fed either by HFD or SC. Seven weeks later, exercise training (HICT/MICT; 8-week, 5-session, 12–30 m/min or 12–21 m/min) and CRO consumption (60 mg/kg) intervention per sessions were performed. The plasma levels of SOD, GSH, and TNF-α and muscle levels of MuRf-1 were assessed using the ELISA method. A two-tailed t-test and one-way ANOVA were applied for data analysis. There was not a significant difference in the protein levels of MuRF1 as the CRO caused an increase in the TNF-α levels as compared to the control. HICT significantly decreased SOD levels as compared to the control, CRO, and MICT. There was no significant difference in GSH levels between intervention arms. Exercise training and CRO supplementations did not make any significant changes in muscle mass regulation factors in the OVX rat model.
