Simulation Gradient Of Alternating Hypoxic Training At An Altitude Of Skeletal Muscle Related Rats The Physiological And Biochemical Indexes

training methods, lanzhou, establish elevation 1500m gradient altitude training model, the animal alternating application physiological and biochemical test method of skeletal muscle and related blood test and analysis, the index of fixed 2500m altitude 4000m, research and training to alternate 25-4000m endurance sports, in order to train high - high alternating athletes to provide the reference.Experimental methods:Experiment with healthy Wister male rats for research object, randomized often aerobic exercise group (CY) and low oxygen in the exercise group, low oxygen in the exercise group is divided again: fixed 2500m altitude (2500m), fixed altitude 4000m group (4000m), 2500-4000m alternating group (JT). Through simulating gradient altitude 4 weeks after hypoxic training alternate 4 days, plain training first five days after weighing on the run in with the speed of 25m/min, instantly ends one-time exhaustion apparatus. Check each rat's weight, time, blood sugar, exhaustion, skeletal glycogen SOD, GSH - PX, CAT, MDA, SDH, ATPase and LDH and plasma La index of different change.Results:(1)during the experiment, each rat's weight change no significant difference in rats, the experimental effect is not obvious changes in weight.(2)alternate hypoxic training can obviously improve the rat endurance.(3)alternate hypoxic training can effectively increase in rats, improve exercise ability. This experimental rats blood sugar concentration had little effect.(4)alternate hypoxic training can effectively improve rats and the activity of SOD skeletal CAT, reduce the MDA content.(5)alternate hypoxic training in rats in plasma La metabolism can effectively improve the body's metabolism of aerobic capacity.(6)alternate hypoxic training can effectively improve the rat skeletal SDH, Ca²⁺-ATP, Mg²⁺-ATP, of the enzyme activity.(7)Fixed altitude 2500m hypoxic training can effectively increase the rat skeletal GSH - PX and LDH and making Na⁺-K⁺-ATP activity. Conclusion:After 4 weeks simulation gradient hypoxic training at an altitude of alternate recovery after 4 days of training plain groups, experimental study were observed in rats, can see the index 4000m group may be due to low oxygen in rats, the stimulation relative training effect is not obvious. Simulation 2500m 4000m alternate hypoxic training relatively appropriate height and load, make oxygen transport capacity and antioxidant capacity and the ability to clear the conversion of mitochondria, strengthen the synthesis, oxidative phosphorylation enhance ability, thus improving the rats sports ability was improved.
