This study examined the angular specificity and test mode specificity of strength training. Six males and six females (X = 22.6 years) were assigned to groups which trained either isometrically (90 degrees ) or isokinetically (30 degrees /second). They trained their left elbow extensors at 80% of their maximum voluntary contraction on a modified Cybex(R) apparatus for 10 weeks, three sessions per week, with 50 contractions per session. Before and after training, both groups were tested isometrically (70, 90, 110 degrees ) and isokinetically (30 degrees /second). When tested isometrically, both groups improved equally, and strength was increased at all three test angles to about the same extent. When tested isokinetically, both groups improved, but the isokinetic group improved to a greater extent. In conclusion, no angular specificity of training was demonstrated within 20 degrees of the training angle, and no test mode specificity was seen for isometric testing. However, isometric training showed less transfer to an isokinetic test. J Orthop Sports Phys Ther 1983;5(2):58-65.
本研究考察了力量训练的角特异性和测试模式特异性。六名男性和六名女性（X = 22.6 岁）被分为两组，分别进行等长（90 度）或等速（30 度/秒）训练。他们使用改良的 Cybex（R）设备以 80%的最大自主收缩力训练左肘伸肌，每周 3 次，每次 50 次收缩，持续 10 周。在训练前后，两组均进行等长（70、90、110 度）和等速（30 度/秒）测试。等长测试时，两组的表现都相当，在所有三个测试角度的力量都增加了大致相同的程度。等速测试时，两组都有改善，但等速组的改善程度更大。总之，在训练角度的 20 度范围内没有表现出角特异性，等长测试也没有表现出测试模式特异性。然而，等长训练对等速测试的转移效果较差。《矫形与运动物理治疗杂志》1983 年；5（2）：58-65。
