摘要
目的:分析篮球运动员髌股关节疼痛综合征的原因,以及股四头肌等长收缩训练的作用。方法:选择上海市体育局有髌股关节疼痛综合征的篮球运动员20名为研究组,无髌股关节疼痛综合征的健康运动员28名为对照组,分析2组Q角及髌骨运动轨迹的差异。研究组采用股四头肌等张收缩+等长收缩的训练方式;对照组采用股四头肌等张收缩的训练方式,比较训练过程中2组髌股关节疼痛的发生率及2种训练方式对股四头肌的训练作用。结果:2组Q角差异无统计学意义,但研究组髌骨运动轨迹异常的发生率高于对照组(P<0.05)。训练过程中2组髌股关节疼痛的发生率差异无统计学意义。研究组训练前后股四头肌肌力改变与对照组比较差异无统计学意义,但肌肉耐力改变较对照组下降(P<0.01)。结论:篮球运动员髌股关节疼痛综合征的发生与Q角没有明显的关系,但与髌骨运动轨迹异常有关。与等张收缩训练方式相比,等张收缩+等长收缩的训练方式对股四头肌肌力改变的作用相同,但在提升肌肉耐力方面有所不足。
Objective：To analyze the etiology of patellofemoral pain syndrome（PFPS）in basketball players and the effect of isometric exercise of the quadriceps femoris.Methods：A total of 20 basketball players from Shanghai sports bureau with PFPS were selected as research group,and 28 healthy player without PFPS were chosen as control group.The differences regarding the Q-angle and the moving track of patella between the 2 groups were analyzed.The training method in the research group consisted of quadriceps femoris isometric and isotonic contraction while that in the control group was isotonic contraction.The incidence rate of patellofemoral pain during the training,as well as the effect of two kinds of training on the quadriceps femoris,was analyzed.Results：There was no significant difference regarding Q-angle between the 2 groups.The incidence rate of patella maltracking in the research group was higher than that in the control group（P〈0.05）.There was no significant difference regarding the incidence rate of patellofemoral pain during the training between the two groups.There was no significant difference regarding the force change of quadriceps femoris after training between the two groups,however,the muscular endurance change in the research group was lower than that in the control group（P〈0.01）.Conclusions：The occurrence of PFPS in basketball player was not significantly related to Q-angle,however,it was related to patella maltracking.Comparing to the isotonic exercise,the training method consisting of isometric and isotonic contraction can achieve a similar effort regarding muscle force,but muscular endurance.
