Effects of Aerobic Exercise Combined with D-Ribose Supplementation on Anti-fatigue and Anti-oxidation in Mice

Study the effects of aerobic exercise combined with D-ribose supplementation on the anti-fatigue and antioxidant enzyme activities of mice, the mice were divided into quiet control group, aerobic exercise control group, D-ribose control group, D-ribose+aerobic exercise group. The aerobic exercise group received aerobic treadmill training for 6 days a week, and the D-ribose group was given 2 mL of ribose (300 mg/100 g) per rat per day. After 12 weeks of regular aerobic treadmill training, an anti-fatigue animal model was established for mice swimming with weight, the time of exhausted swimming was recorded in mice, and hepaticr glycogen (HG), muscle glycogen (MG), and blood glucose in mice, blood urea nitrogen (BUN), blood lactic acid (BLA), malondialdehyde (MDA) content and total antioxidant capacity (T-AOC), glutathione Oxide dismutase (glutathione peroxide dismutase, GSH-Px), superoxide dismutase (SOD), catalase (catalase, CAT) and other activities were measured. The results showed that compared with the quiet control group, the weight-bearing swimming time of mice in the aerobic exercise control group, D-ribose control group, and D-ribose+aerobic exercise group significantly increased (P<0.05), and at the same time the mice's body hepatic glycogen, muscle glycogen and blood sugar content were significantly improved(P<0.05), and the blood urea nitrogen and blood lactic acid content in the body were significantly reduced(P<0.05). In addition, the results of its antioxidant activity showed that compared with the quiet control group, the T-AOC of the aerobic exercise control group, D-ribose control group, D-ribose+aerobic exercise group were all enhanced. The activity of SOD, CAT, GSH-Px also significantly increased (P<0.05), and MDA was significantly reduced (P<0.05). It showed that long-term regular aerobic exercise combined with D-ribose supplementation could significantly increase the liver glycogen, muscle glycogen, blood sugar content and oxidative stress ability in the body, and improve the body's anti-fatigue effect.
