One of the strategies reported in the scientific literature is the application of interventions witheccentric exercises. To verify the effectiveness of these interventions, different eccentric strength measurementshave been used with low-cost devices as alternatives to the widespread used isokinetic dynamometers and thetechnically limited handheld dynamometers. Therefore, the purpose of the present systematic review was tosummarize the findings of the scientific literature related to the evaluation of eccentric strength of hamstringmuscles with these new technologies.Methods: Systematic searches through the PubMed, Scopus, and Web of Science databases, from inception up toApril 2020, were conducted for peer reviewed articles written in English, reporting eccentric strength of hamstringsassessed 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 parametersidentified. The pooled sample consisted of 2893 participants (97% male and 3% female: 22 ± 4 years). Theparameters 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 eccentrichamstrings strength and both injury risk and athletic performance. There is no standardized definition orstandardization of the calculation of the used parameters.Conclusions: The current evidence is insufficient to recommend a practical guide for sports professionals to usethese 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 ofhamstring muscles assessed by different devices may be recommended for monitoring the neuromuscular status ofathletes PB Springer SN 2199-1170 LK https://hdl.handle.net/10612/19116 UL https://hdl.handle.net/10612/19116 NO Claudino, J.
