Abstract
Abstract Introduction: Given the practicality and low cost of elastic devices, a comparison with conventional devices may be able to quantify gains from both tools for further conclusions. Objective: Compare the effect of resistance training with elastic (tubes and resistance band) and conventional (weight machines and dumbbells) devices on body composition. Method: This is a systematic review and meta-analysis. The PubMed/MEDLINE, Embase, PEDro and CENTRAL databases were searched from the earliest records to July 25, 2018. Data were described in standardized mean difference (SMD) with a 95% confidence interval (95% CI). Results: Four studies were included. The results of the meta-analysis did not show superiority among the analyzed methods for the variables investigated (SMD = -2.04, 95% CI -7.56, 3.48, p < 0.00001, lean mass: SMD = 0.28, 95% CI -0.29, 0.85, p = 0.97, body fat: SMD = 2.77, 95% CI -0.05, 5.59, p = 0.92, body mass: SMD = 1.22, 95% CI -0.29, 2.74, p = 0.11). Conclusion: The results of the meta-analysis showed superiority of outcome from training in conventional devices only for the variable fat mass. For the other variables, no statistically significant differences were found. Elastic resistance can promote similar outcomes to resistance in different population profiles and from various protocols on variables related to body composition.

Summary
Given the practicality and low cost of elastic devices, a comparison with conventional devices may be able to quantify gains from both tools for further conclusions. Objective: Compare the effect of resistance training with elastic (tubes and resistance band) and conventional (weight machines and dumbbells) devices on body composition. Resistance exercises can be performed in different scenarios, with several implements such as dumbbells, weight machines, exercise balls, body mass and elastic devices [1,2,3]; and is an essential strategy in physical therapy rehabilitation protocols for any population profile as well as intended outcomes [4,5,6,7,8]. Despite the described benefits of using conventional devices for resistance training, their use comprise low accessibility conditions [12]. It is worth highlighting the embarrassment that performing activities with other people may cause [13,14]. These factors may influence the dropout of a significant percentage of people who start this type of physical activity, and evidence shows that 50% of the public enrolled in gyms drop out during the first year [15]
