Physical exercise is now a widely known and studied factor of the proper functioning of living organisms. Many questions remain unanswered concerning various aspects of the changes in the morphology of structures subjected to chronic physical exercise.
This study was conducted on fifty Buffalo strain rats, randomly divided into two equal (experimental and control) groups. All animals were subjected to physical training on a running track for 10 weeks, whereas only in the experimental group, massage was additionally applied five-times per week.
An increase in the percentage of collagen fibers in tendons with the smallest diameter (≤100 nm) was observed only in the experimental group in week 3, followed by a decrease in weeks 5 and 7. A subsequent repeated increase was observed in week 10 of the study. No significant differences were observed for either study group in the number of collagen fibers based on fiber diameter (101-200 nm, 201-300 nm and 301-400 nm).
The results of this preliminary study showed that long-term massage performed during running training may initiate for small structural changes in the rat tendon. Further morphological studies with prolonged observation periods are recommended.
体育锻炼如今是一个广为人知且经过研究的影响生物体正常功能的因素。关于长期体育锻炼后结构形态变化的各个方面，仍有许多问题未得到解答。
本研究以五十只布法罗品系大鼠为对象，随机分为两个相等的组（实验组和对照组）。所有动物在跑道上进行为期10周的体育训练，而仅在实验组中，每周额外进行五次按摩。
仅在实验组第3周观察到直径最小（≤100纳米）的肌腱中胶原纤维百分比增加，随后在第5周和第7周下降。在研究的第10周观察到随后的再次增加。基于纤维直径（101 - 200纳米、201 - 300纳米和301 - 400纳米），两个研究组在胶原纤维数量上均未观察到显著差异。
这项初步研究的结果表明，跑步训练期间进行的长期按摩可能引发大鼠肌腱的微小结构变化。建议进行更长观察期的进一步形态学研究。
