The authors investigated the effects of 2 weeks of heavy index finger strength training on characteristics of freely chosen finger tapping including tapping frequency, tap force, and finger displacement. One group (n = 12) performed index finger extension and flexion strength training. A control group (n = 12) performed no intervention. Results showed that the training group increased strength in both extension (19.5 ± 22.2%, p = .015) and flexion (9.4 ± 9.8%, p = .001) from pretest to posttest. Furthermore, training did not affect the frequency and the pattern of the tapping movement (Fs = 0.004-3.441, ps = .077-.954). The present results are in contrast to previous findings of reduced movement frequency and altered movement pattern during ergometer pedaling after strength training. This difference may be explained by the dissimilarity between the 2 tasks.
作者们研究了为期两周的高强度食指力量训练对自由选择的手指敲击特征的影响，这些特征包括敲击频率、敲击力度和手指位移。一组（n = 12）进行食指伸展和弯曲力量训练。对照组（n = 12）不进行干预。结果显示，训练组从测试前到测试后，伸展力量（19.5 ± 22.2%，p = .015）和弯曲力量（9.4 ± 9.8%，p = .001）均有所增加。此外，训练并未影响敲击动作的频率和模式（Fs = 0.004 - 3.441，ps = .077 - .954）。目前的结果与先前关于力量训练后测力计蹬踏过程中运动频率降低和运动模式改变的研究结果相反。这种差异可能是由这两项任务的不同所致。
