In this paper, the relationship between Q-angle (QA) and occurrence of chondromalacia patellae (CP)was studied in 111 Chinese elite male volleyball players using the method of clinical epidemiology. The studyshowed that the incidence of CP was 39.6% and it suggested that CP was the most frequently seen sportsinjuries in the knee joint among volleyball players. No significant difference was found between left andright sides regarding the CP incidence, but the incidence increased obviously with the age and the...

In this paper, the relationship between Q-angle (QA) and occurrence of chondromalacia patellae (CP)was studied in 111 Chinese elite male volleyball players using the method of clinical epidemiology. The studyshowed that the incidence of CP was 39.6% and it suggested that CP was the most frequently seen sportsinjuries in the knee joint among volleyball players. No significant difference was found between left andright sides regarding the CP incidence, but the incidence increased obviously with the age and the length ofathletic career. The incidence of enthesiopathy at upper pole of patellae was 19.8% and was just next toCP, which should be in high alert. The average QA of total male volleyball players was 13°±3°, while average QA in players with CP(14°±3°) was significantly greater than that in players without CP (12°+3°). The greater the QA was, thehigher the incidence of CP appeared. The relationship could be expressed with a linear regression equation:y = 3.224x - 0. 1, with a correlative coefficient: r = 0.825. Therefore QA could be considered as a referenceindex for prospective volleyball players selection. Players with sound QA ought to be selected more prefera-ble than those with too large QA (over 18°). It was suggested that superficial measurement of QA was aneasy and reliable method, also to localize the center of patellae accurately was quite important in both super-ficial and roentgenographic measurements of QA.

本文用临床流行病学方法调查了我国111名优秀男子排球运动员髌骨软骨软化症(CP)的患病情况及与Q角的关系,发现CP患病率达39.6%,占膝伤首位。111名男排队员的平均Q角为13°±3°,其中44例患者的Q角为14°±3°,较未患CP者的Q角12°±3°明显为大。CP患病率与Q角大小密切正相关,r=0.825。认为Q角在发育成熟的个体较恒定,建议作为运动员选材的指标之一。同时也探讨了Q角测量方法、认为体表定位Q角测量是一种简单易行,精确可靠的方法。选取髌骨中点是保证精确测量的关键。

The quadriceps extending moments were measured isokinetically in 28 malevolleyball players to provide data for the biomechanical calculation of patellofemoral joint.The effects of various Q-angles (QA) on shear force (Fs), compressiveforce (Fc) and resultant compressive force (R) of the patellofemoral joint wereanalyzed according to the models of the Nisell's Isokinetic Knee Measurementand the 3-Dimensional Patellofemoral Joint Reactive Force (PFJRF). Mechanicalanalysis to PFJRF showed that increased QA affects Fs obviously and changesthe direction of R lateralwards. The magnitude of knee extending moment ortesting velocity exerts an obvious influence on R and Fc.While QA reached 18degree, Fs and R increased dramatically to 2.1 BW and 6.6 BW in maximumrespectively. Such strong Fs and R directed lateralward will surely result insevere un-uniform distribution of pressure and unstable patellae, which perhapsbring about the rotation of patella within the sulcus of femoral condyles duringknee motions. Therefore it was proved biomechanically that the large QA is anunfavorable factor to the patellofemoral joint of volleyball players.

本文对28名男子排球运动员的股四头肌进行等速肌力测试以提供髌股关节生物力学计算数据。根据膝关节等速测试力学模型和髌股关节作用力(PFJRF)三维力学模型、分析不同Q角对髌股剪切力(Fs),正压力(Fc)和合力(R)的影响。发现Q角增大对Fs影响最大,并使R方向明显偏外。而伸膝肌力大小或测试速度则对R和Fc产生明显影响。当Q角达18°时,Fs最大达2.1BW,R最大达6.6BW。如此之大的Fs及方向偏外的R,将导致压力分布严重不均和髌骨不稳、或许还造成膝关节运动过程中髌骨在股骨髁间沟内的旋转。因此,从生物力学上也证实Q角较大对排球运动员的髌股关节是不利的。

Fie female adolescent volleyballpl ayers aged 14-16 years were selected as subjects. Self-matched control design was adopted and their dietary intake was controlled during the study.Zinc absorption was studied by using the stable isotope "Zn as a tracer with mass spectro-metry and flame atomic absorption spectrophotometry. Zinc balance was also studied in thisexperiment. The results showed that the mean zinc absorption of athletes was 33.5±24.1% in exer-cise training period and 45.6±23.3% in nontraining period, p<0.05. The amount of zincexcretion is higher than that of zinc intake which shows a negative zinc balance in exercisetraining period. The amount of zinc excretion is lower than zinc intake and zinc balance ispositive in nontraining period. The concentration of zinc in sweat was 1.02±0.50mg/l andthe amount of zinc loss from sweat was 38.1% of the zinc absorption per day. The experi-mental results indicated that exercise training may reduce zinc absorption rate. The causesof negative zinc balance of athletes were comprehensive during training period. These results suggested that the zinc requirement of athletes should be increased forathletes in systematic exercise training.

为了解运动员锌缺乏的原因,本文以5名少年女子排球运动员为研究对象,用稳定同位素_(67)Zn 示踪技术研究了运动对锌吸收的影响,结果表明运动使锌吸收率降低,锌丢失量增多,机体处于负锌平衡。
