负重离心收缩诱导人体肱二头肌延迟性肌肉酸痛模型的实验研究
Experimental Study on Human Biceps Delayed Onset Muscle Soreness Model Induced by Centrifugal Elbow Flexion
摘要
Abstract
Objective To observe the method of eccentric contraction weight-bearing on inducing human biceps DOMS model. Methods Subjects, 60 volunteers, were recruited from college students, randomly divided into the model group and control group, 30 cases in each group. The model group was given two groups of movement of centrifugal contraction on weight-bearing, each group contains 25 movements, 20 seconds each movement. The control group was not taken any special movement. The serum creatine kinase (CK), subjective pain threshold, the rate of perceived exertion (RPE) and the volunteers of clinical evaluation criteria (CEC) were observed to evaluate the model. Results Camparing model group with control group, subjective pain threshold in the model group was lower than in the control group after test for 24 hours and48 hours;CK in the model group was higher than the control group after test for 72 hours;RPE in the model group was higher than the control group at ending the test and after test for 24 hours, 48 hours and 72 hours;CEC in the model group was higher than the control group at ending of the test, after test for 24 hours, 48 hours, 72 hours and 120 hours;the differences were statistically significant (P<0.05). After test for 24 hours, 48 hours and 72 hours, subjective pain threshold in model group was lower than before test;after test for 48 hours, 72 hours and 120 hours, CK was higher than before test;at ending of the test and after test for 24 hours, 48 hours and 72 hours, RPE was higher than before test;at ending of the test and after test for 24 hours, 48 hours, 72 hours and 120 hours, CEC was higher than before test;the differences were statistically significant (P<0.05). Conclusion The method of eccentric contraction during weight-bearing could be used for establishing human biceps DOMS model, and the changes of various indicators are in accordance with the literature.关键词
