Résumé : |
Background: Hamstring Strain Injury (HSI) is one of the most common injuries in track and field sports, accounting for over 12% of all lower extremity sport injuries and these injuries mainly involve the Biceps Femoris Long Head (BFLH). Eccentric Strength Training (EST) has showed to reduce hamstring injuries. Although literature focus prevention programs on modifiable HSI risk factors such as eccentric hamstring weakness and muscle architecture characteristics, the mechanism behind this reduction remains unclear. This systematic review is aimed at describing the effects of an eccentric hamstring strength training on biceps femoris long head architecture and eccentric hamstring strength, on healthy adults.
Methods: A systematic review of Randomized Controlled Trials (RCTs) was conducted to identify relevant studies in the databases PubMed, PEDro, CINAHL and SPORTDiscus up to october 2018 (PROSPERO registration number : CRD42018109572). Included studies enrolled healthy adults, performing at least a 4-week EST. Data including study design, participants characteristics, and exercise/interventional characteristics were extracted from individual trials. The mean difference of eccentric hamstring strength and BFLH architecture were extracted or calculated from individual trials and, when possible, a meta-analysis was performed. Results: Ten RCTs were included in this review, and 9 were included in the meta-analysis. In these, architectural modifications were assessed into 6 studies, while eccentric hamstring strength was assessed by all studies. Quantitative analysis reported statistically significant evidence that eccentric strength training, compared to control groups, is associated with an increase in eccentric hamstring strength, an increase in fascicle length, an increase in muscle thickness and a decrease in pennation angle, on healthy adults. Conclusion: This systematic review suggested that HSI prevention strategies including eccentric strength training should consider both eccentric hamstring strength and structural adaptations. However, future research is needed to confirm these findings and determine guidelines in exercise selection and standardized training methods to adopt in clinical practice. |
