The purpose of this study was to compare the effects of isometric strength training of the nondominant left abductor digiti minimi muscles of young and aged women. The ten young subjects, mean age 22.6 years, were all nursing students. The ten older subjects, mean age 69.2 years, did not constitute a similar homogeneous group, although they all lived in the metropolitan area of Richmond, VA. All subjects were volunteers. Training consisted of each subject performing 20 maximal isometric contractions of the left abductor digiti minimi three times weekly for six weeks. A pretest and six weekly measurements of strength were made on a strain gauge. Significant strength increases were found for the pretest-posttest measurements within each group at the same p less than 0.0001 level. When both groups were compared on the initial strength measurement and on the six weekly measurements, no statistically significant differences were found. Therefore, the null hypothesis was accepted.
本研究的目的是比较年轻女性和老年女性非优势侧左手小指展肌等长力量训练的效果。十名年轻受试者，平均年龄22.6岁，均为护理专业学生。十名老年受试者，平均年龄69.2岁，尽管他们都居住在弗吉尼亚州里士满的大都市区，但并不构成一个相似的同质群体。所有受试者均为志愿者。训练内容为每位受试者每周进行三次、每次20次左手小指展肌最大等长收缩，持续六周。使用应变仪进行了一次预测试和六周的力量测量。在每组的预测试 - 后测试测量中，在相同的p小于0.0001水平下发现力量有显著增加。当比较两组的初始力量测量和六周的测量结果时，未发现统计学上的显著差异。因此，原假设被接受。
