Abstract [en]

Background and Purpose

: Several studies have shown that stretching increases flexibility and therefore stretching has become a conventional method. However, there are theories but few studies on eccentric training and its influence on flexibility. The current studies have confirmed an increased fascicle length (FL) and range of motion (ROM) and thereby flexibility. The purpose of this review article was to examine the effects of traditional stretching and eccentric training on muscle flexibility, and to conclude if eccentric training can be used as an alternative. Method: For the investigation, the inclusion criteria for literature search, were set to publication date 2007-2017, peer reviewed or refereed (quality assured), both gender included, animal and human studies, language English and full text available. The databases PubMed, SPORTDiscus and Google Scholar, were searched, with search terms in different combinations, from Mars to May 2017. References from extracted articles were used, with inclusion criteria mentioned above except for no time limitation. Results and Conclusion: Stretching and eccentric training seem to have some similar physiological adaptations. Stretching has shown to increase flexibility through sarcomerogenesis, and eccentric training has proved to increase flexibility through increased FL. Sarcomerogenesis and FL are interrelated which confirms that these results from both stretching and eccentric training can depend on sarcomerogenesis. There are other physiological adaptations with both stretching and eccentric training, but these adaptations cannot be compared because of lack of investigation. Therefore, the results from this study only confirm that eccentric training can give some similar effects on flexibility as stretching but more research needs to be done to confirm this theory.
