Abstract
Different equipment has been built as alternative strategies to maximize training effect, such as THE DISQ® device. However, there is a lack of physiological information about this equipment effectiveness on cardiometabolic responses. The purpose of this study was to compare the influence of DISQ® device on cardiometabolic effect in adults. Fifteen healthy subjects were randomized and submitted to two maximal treadmill incremental cardiopulmonary exercise test with (DISQ® GROUP-DG) and without (CONTROL GROUP-CG) DISQ® device. It was determined the anaerobic threshold (AT), respiratory compensation point (RCP) and exercise exhaustion point (EP), velocity (V), time to reach the ventilatory thresholds (T), maximal heart rate (HR), oxygen consumption (Ox: L/min and ml/kg.min-1) and energy expenditure (EE). Results evidenced that DG presented lower (p<0.001) V at RCP and EP than CG. No differences were found at AT between groups. The Time of DG was lower (p<0.001) at AT and RCP than CG. On the other hand, EP were similar between groups. No differences were found on AT, RCP and EP respectively to HR. In the Ox, no differences were found to AT and RCP between DG and CG. However, the EP was different (p<0,05) to Ox. The EE was significantly lower (p=0.03) in EP between the CG and the DG. Although our data indicates that velocity, time to reach the T and EE were lower to DG (in EP), the maximal heart rate and oxygen consumption did not differ with DISQ® device, suggesting that higher peripheral neuromuscular fatigability should be concerned to data explanation.

Introduction
Running is one of the most popular forms of physical activity in the world, being practiced by individuals who seek to improve health, quality of life, weight loss, and the improvement of physical fitness (Hespanhol Junior et al., 2015). In addition, other factors favor the popularity of running, such as being a natural and inherent activity in humans, being easy to practice, having independence in the use of equipment and presenting low cost (Ooms et al., 2013).
Due to the feasibility of performing the activity, the most frequently used ways to increase total physical work in...
