Effect of training on dimensions of muscle fibres of fast twitch and slow-twitch types were studied in three groups of subjects: local training of m. triceps surae (volunteers) in laboratory conditions, training of amateur joggers and of elite racers--skiers. Significant negative correlations between initial level and training-induced changes of muscle fibre cross sectional areas were demonstrated. The correlations found indicate that muscle fibre dimensions of people using similar endurance training programme tend to some certain level which is likely to be the optimal for this type of training. Dimensions of muscle fibre may significantly change as the result of traiining, probably, only in the case, when their initial values differ from the optimal one.
在实验室条件下对腓肠肌进行局部训练（志愿者）、对业余慢跑者和精英赛跑运动员——滑雪运动员进行训练。结果表明，肌肉纤维横截面积的初始水平与训练引起的变化之间存在显著的负相关。所发现的相关性表明，采用相似耐力训练计划的人的肌肉纤维维度往往趋于某个特定水平，而这个水平可能是此类训练的最佳水平。肌肉纤维的维度可能仅在其初始值与最佳值不同的情况下，才会因训练而发生显著变化。
