Materials and methods:Male Sprague—Dawley rats were randomly divided into four groups as follow:Normoxia sedentary group,Hypoxic exposure group,Normoxia exercise group,living high training low group.the normoxia sedentary group lived in normoxic environment,hypoxic exposure group made hypoxic exposure for 12h in normobaric hypoxic tent(oxygen concentration 13.6%),Normoxia exercise group took 1h endurance exercise in normoxic environment at daytime,Hiho group was exposured in hypoxia at night after trained at daytime,the mode and duration of the both load were identical to hypoxic exposure group and normoxia exercise group.
