在为期8周的等张强度训练方案的过程中，7名年轻男性和8名女性的力量增益与神经因素和肥大的贡献的时间过程进行了研究。结果表明，神经因素在初始力量增长中所占的比例较大，此后神经因素和肥大共同参与力量的进一步增长，在最初3 ~ 5周后，肥大成为主导因素。我们关于未经训练的对侧手臂屈肌的数据为交叉训练的概念提供了进一步的支持。有人认为，这种交叉教育效果的性质可能完全取决于神经因素，这些因素可能作用于神经系统的各个层面，从而导致肌肉激活的最大水平增加。
The time course of strength gain with respect to the contributions of neural factors and hypertrophy was studied in seven young males and eight females during the course of an 8 week regimen of isotonic strength training. The results indicated that neural factors accounted for the larger proportion of the initial strength increment and thereafter both neural factors and hypertrophy took part in the further increase in strength, with hypertrophy becoming the dominant factor after the first 3 to 5 weeks. Our data regarding the untrained contralateral arm flexors provide further support for the concept of cross education. It was suggested that the nature of this cross education effect may entirely rest on the neural factors presumably acting at various levels of the nervous system which could result in increasing the maximal level of muscle activation.
