高强度复合式训练对健美操选手体脂及组织损伤的影响研究

On High Intensity Compound Training in Body Fat and Tissue Damage of Aerobics

目的:探讨高强度训练(HIT)与高负荷训练(HVT),对健美操运动员组织损伤的影响.方法:针对健美操选手进行为期12周高强度复合式训练,并于运动前、训练中、训练后对受试者血清肌肉损伤的生化指标、体脂率等进行监测.结果:(1)高强度复合式训练能显著降低受试者体质量、体脂、甘油三酯、总胆固醇及尿素氮浓度;(2)提升血液葡萄糖、乳酸、肌酸酐浓度,增强天门冬胺酸转胺酶及肌酸激酶活性;(3)血液中的肌肉损伤指标值的提升与体脂下降率呈负相关,这暗示高强度复合式训练有利于肌肉再生,从而促使脂肪组织下降.结论:12周高强度复合式训练使健美操选手体脂明显减少、血液中肌肉损伤指标值提升,表明该训练方式可以促使肌肉再生,吸引全身含碳资源重新分配,使脂肪组织下降、肌肉组织增加,强度越高,碳资源重新分配效果越好.

High intensity training（HIT）and high load training（HVT）have now become an important part of the daily training of many high-level bodybuilders in the world.However,there is a lack of the research results in this field in our country＇s bodybuilding projects,especially the research on the organization damage of Aerobics athletes is almost blank.Aerobics athletes have been trained for 12 weeks with high-intensity combined training in this study.The biochemical indexes and body fat rates of serum muscle injury were monitored Pretest,middle test and post test after exercise.Results show that,1）High strength composite training can significantly reduce the body weight,body fat,triglycerides,total cholesterol and urea nitrogen concentration;2）Improve blood glucose,lactate,creatinine concentration,enhanced aspartate aminotransferase and creatine kinase activity;3）Improve muscle blood and body fat damage index the value of the rate of decline was negatively correlated,suggesting that the high strength composite training for muscle regeneration and promote adipose tissue decreased.It is concluded that the 12 week high intensity compound training made the body fat of the aerobics significantly reduced and the index of muscle injury in the blood increased.It shows that the training method caused the muscle regeneration to attract the whole body carbon resource redistribution,and the fat tissue decreased the muscle tissue,the higher the intensity,the better the carbon resource redistribution effect.
