Data are given as the mean ± SD. CK = creatine kinase, CK-MB = creatine kinase–MB, LDH = lactate dehydrogenase. * P<0.05, relative to baseline, & P<0.05, relative to high altitude values, # P<0.05, relative to 3rd day values, ^P<0.05, relative to 50th day values, △ P<0.05, relative to the control group.
