Study Overview
Brief Summary
Introduction: The isokinetic dynamometer, considered a gold standard tool for physical evaluation, is widely used in studies that aim to evaluate the reliability and reproducibility of localized muscular endurance (LME) tests. However, such tests may not represent full LME by fixing time or number of replicates. Therefore, it is relevant to construct a test that respects the actual capacity of each subject to withstand fatigue and to submit such a test to validation, as well as to physiological analysis.
Research objectives: To assess the inter- and intra-rater reliability of a localized isometric endurance test (IET) on the isokinetic dynamometer and to establish the metabolic demand required during the test.
Design: Reliability study with test-reteste dynamic.
Participants and Setting: After fulfilling the eligibility criteria, eighty-eight male participants will participate in the study.
Procedure: In phase 1 forty-eight participants will submitted to reliability of the IET within three sessions: familiarization session, test session and retest sessio. In phase 2 forty participants will be submitted the metabolic demand required during the IET will be analyzed by means of gas analysis, blood lactat concetrate and muscular activation percentage.
Intervention: isometric endurance teste.
Measurements: The measurements include time of execution of test, work of test, physiological and psychological outcomes.

Participants and Setting: After fulfilling the eligibility criteria, eighty-eight male participants will participate in the study. The inclusion criteria include: healthy male, aged between 18-30 years who agree to participate in the study. Participants with the following will be excluded from the study: presence of anemia, inflammation, being sick, training or physical activity at least 24 hours prior the application of the test, being influenced in some way by test information, do not understand the teste and occurrence of musculoskeletal injury during the study.

Arms & Interventions
Reliability of IET
In phase 1, the first of familiarization is to the participants understand the test and familiarize with the equipment after 24 to 48 hours, the participants will do the test applied twice at the same day with 10 minutes of rest. For realization of the IET the participants will be instructe to make the maximum effort as possible and mantain until they can't resiste. After one week the retest session will be doing. The order between the evaluators will be changed in the test and retest sessions.
Intervention: Reliability of IET (Diagnostic Test)
Physiological analysis of IET
In phase 2, the participants will be submitted two sessions, familiarization session and test session. In the test session there is be two teste applied in the same day with approximately 20 minutes of rest. In the first test, thers is gas analysis during all the test until seven minutes after the test and blood lactat concentrate will be colected before the test with 10 minutes of rest, immediately after the teste and in the first, in the third, fifth and seventh minutes after the test. In the second test will be assess the muscular activation porcentage of lateral vastus muscle by means of twitch interpolation technique there is be performe before and after the test.
Intervention: Physiological analysis of IET (Diagnostic Test)
Outcomes
Primary Outcomes

Time Frame: 45 seconds after the beginning of the test
This outcome will be assessed in seconds during execution of the test
Secondary Outcomes
- Borg Scale(Day 7)

- Muscular activation percentage(Day 2)
- Work Ability Index Questionnaire(Day 1)
- Perceived Stress Scale(Day 1)
- Bergen Insomnia Scale(Day 1)
- Need for Recovery Scale(Day 7)
