Abstract

The influence of pretest hand-resting time and induction time on kinesthetic aftereffect was determined for 22 males and females. Aftereffect was assessed with the apparatus of Koehler and Dinnerstein (1947). Three separate tests of aftereffect were administered. Each was preceded by either a 10-, 20-, or 30-min. hand-resting period. Significant differences in aftereffect were not found between pretest conditions. Scores were also determined for varying induction times at each pretest condition. Induction periods totaling 90-, 180-, and 300-sec. were used. Aftereffect was significantly less pronounced following 90 than 180 sec. of induction for the 10-and 20-min. pretest conditions but was the same following 90, 180, and 300 sec. of induction for the 30-min. condition. Results indicated that less than 300 sec. of induction could be used regardless of the duration of the pretest period. However, because the internal validity of the 180-sec. score was significantly better than the 90-sec. score, it was concluded that at least 180 sec. of induction were needed.

摘要

对22名男性和女性受试者，研究了预测试时手部静止时间和诱导时间对运动后效的影响。运动后效采用Koehler和Dinnerstein（1947年）的仪器进行评估。进行了三项独立的运动后效测试。每次测试前，手部静止时间分别为10分钟、20分钟或30分钟。预测试条件之间未发现运动后效存在显著差异。还测定了每种预测试条件下不同诱导时间的得分。诱导时间分别为90秒、180秒和300秒。在10分钟和20分钟的预测试条件下，诱导90秒后的运动后效明显弱于诱导180秒后的情况，但在30分钟的预测试条件下，诱导90秒、180秒和300秒后的运动后效相同。结果表明，无论预测试时间长短，诱导时间少于300秒均可。然而，由于180秒得分的内部效度显著优于90秒得分，因此得出结论，至少需要180秒的诱导时间。
