Abstract
[EN] Background: Given the severe economic and performance implications of hamstring injuries, there are different
attempts to identify their risk factors for subsequently developing injury prevention strategies to reduce the risk of
these injuries. One of the strategies reported in the scientific literature is the application of interventions with
eccentric exercises. To verify the effectiveness of these interventions, different eccentric strength measurements
have been used with low-cost devices as alternatives to the widespread used isokinetic dynamometers and the
technically limited handheld dynamometers. Therefore, the purpose of the present systematic review was to
summarize the findings of the scientific literature related to the evaluation of eccentric strength of hamstring
muscles with these new technologies.
Methods: Systematic searches through the PubMed, Scopus, and Web of Science databases, from inception up to
April 2020, were conducted for peer reviewed articles written in English, reporting eccentric strength of hamstrings
assessed by devices, different to isokinetic and handheld dynamometers, in athletes.
Results: Seventeen studies were finally included in the review with 4 different devices used and 18 parameters
identified. The pooled sample consisted of 2893 participants (97% male and 3% female: 22 ± 4 years). The
parameters most used were peak force (highest and average), peak torque (average and highest), and between-
limb imbalance (left-to-right limb ratio). There is inconsistency regarding the association between eccentric
hamstrings strength and both injury risk and athletic performance. There is no standardized definition or
standardization of the calculation of the used parameters.
Conclusions: The current evidence is insufficient to recommend a practical guide for sports professionals to use
these new technologies in their daily routine, due to the need for standardized definitions and calculations.
Furthermore, more studies with female athletes are warranted. Despite these limitations, the eccentric strength of
hamstring muscles assessed by different devices may be recommended for monitoring the neuromuscular status of
athletes
