Brief Summary

Introduction: The exercise performed with elastic tools has been appearing in the current scenario as a clinical tool because it presents advantages such as easy handling, low cost and safety. However, its use as an assessment tool, specifically for localized muscular resistance, is reduced and not standardized. In addition, there are no records of the physiological / neurofunctional effects of tests that use such a tool, since it allows a differentiated degree of prescription. Objective: To determine the reliability and reproducibility of a shoulder abduction resistance test in two tools, elastic tube and isokinetic dynamometer. In addition to analyzing the metabolic profile of both comparative order and targeting subsequent training prescription. Method: The study will consist of a sample of 30 participants and will be carried out in 2 stages, 15 participants will perform step 1 and the other 15 will perform step 2. The difference between the steps is the order of the tools used to perform the test . Each stage will consist of 5 sessions (Orientation, Familiarization 1 and 2, Test and Retest). During the test and retest sessions the physiological response of the test will be analyzed. In order to observe the response, will be analyzed the lactic anaerobic parameter (lactate concentration), allelic anaerobic (post-exercise oxygen uptake analysis - EPOC), aerobic parameter (VO2 values) and electromyographic measurements. Will be used the statistical package SPSS Statistics 22.0, Pearson's correlation and their respective confidence intervals will indicate the relationship between the numerical variables and multivariate models will be constructed by means of linear regression. The significance level of 5% will be adopted.

Outcome Measures

Primary Outcomes (2)

• Change in time values

  It will be divided into two stages. The 30 participants recruited will be randomized to perform the steps, 15 participants will perform step 1 and the other 15 participants will perform step 2. The difference between the participants is between the order of the procedures. In stage 1 the participants will perform 4 tests, the two tests initially with the device tube elastic the two ends with the isokinetic dynamometer, with 30 minutes interval between tests. For step 2, another 15 participants will perform the same procedures with the order of alternate tools. The change time values will be analyzed for reliability and reproducibility of the test.

  1 minute post test

• Change in repetitions values

  It will be divided into two stages. The 30 participants recruited will be randomized to perform the steps, 15 participants will perform step 1 and the other 15 participants will perform step 2. The difference between the participants is between the order of the procedures. In stage 1 the participants will perform 4 tests, the two tests initially with the device tube elastic the two ends with the isokinetic dynamometer, with 30 minutes interval between tests. For step 2, another 15 participants will perform the same procedures with the order of alternate tools. The change on repetitions values will be analyzed for reliability and reproducibility of the test.
