The effect of strenuous exercise on lipoprotein level and composition as well as on lipoprotein lipase activity (LPLA) and glycogen stores in skeletal muscle was studied in 16 healthy young men after military field maneuvers. Body weight was reduced by 1 kg after the maneuvers and was gradually restored during a 5-day recovery phase. Glycogen levels were reduced by 50% and LPLA increased threefold immediately after the exercise, and neither were restored until 3-5 days of recovery. Serum triglycerides were decreased by about 50% after 1 day of recovery and the cholesterol concentration in high-density lipoproteins increased but only immediately after exercise. In contrast, the apolipoproteins A-I and A-II, the main protein constituents, were both decreased and remained so for 3-5 days. The results indicate that significant alterations of plasma lipoprotein level and composition as well as of muscle metabolism occur after prolonged physical exertion and that some changes are still evident after 5 days of recovery.
在16名健康年轻男性参加军事野外演习后，研究了剧烈运动对脂蛋白水平和组成以及对骨骼肌中脂蛋白脂肪酶活性（LPLA）和糖原储备的影响。演习后体重减轻了1kg，并在5天的恢复阶段逐渐恢复。运动后糖原水平立即降低了50%，LPLA增加了三倍，直到恢复3-5天两者才恢复。恢复1天后血清甘油三酯降低了约50%，高密度脂蛋白中的胆固醇浓度增加，但仅在运动后立即增加。相比之下，主要蛋白质成分载脂蛋白A-I和A-II均降低，并在3-5天内持续降低。结果表明，长时间体力消耗后血浆脂蛋白水平和组成以及肌肉代谢发生了显著变化，并且在恢复5天后一些变化仍然明显。
