摘要

对30名19 ~ 39岁健康女性右侧肱二头肌和右侧股直肌进行转弯/振幅分析。干扰模式被记录在两个肌肉的个人最大力量的20%,40%和60%。我们评估了转弯/秒、幅度/转弯以及幅度/转弯:转弯/秒和转弯/秒:幅度/转弯的比值。在定义的力水平(表1和图2)和云的形式(图3)下,转弯/振幅参数的正常值以±2 SD的平均值计算(表1和图2)。我们的云与Stalberg的云明显不同。由于我们和其他研究的正常值不一致,我们认为每个实验室都必须制定自己的正常值。转数/秒、幅度/转数和转数/秒比:随着力的增加,幅度/转数增加,比例幅度/转数/秒减少(图6和7)。与股直肌相比,肱二头肌的转数/转数参数部分显著高于或低于股直肌(图8)。

[Potential reversal/amplitude analysis: problems of normal value determination].

Turn/amplitude-analysis was applied to the right m. biceps brachii and the right m. rectus femoris of 30 healthy women aged 19 to 39 years. Interference patterns were recorded at 20, 40 and 60% of the individual maximum force of both muscles. We evaluated the turns/s, the amplitude/turn and the ratios amplitude/turns:turns/s and turns/s:amplitude/turn. Normal values of the turn/amplitude-parameter were calculated as means +/- 2 SD at defined levels of force (table 1 and fig. 2) and in form of clouds (fig. 3). Our clouds were clearly different from those of Stalberg. Since normal values of our and other studies were inconsistent we believe that every laboratory has to elaborate its own normal values. Turns/s, amplitude/turn and the ratio turns/s:amplitude/turn increased and the ratio amplitude/turns/s decreased with increasing force (fig. 6 and 7). Turn/amplitude-parameters were partly significantly higher or lower in the m. biceps brachii than in the m. rectus femoris (fig. 8.).
