Sedentary Behavior Breaks With Isometric Exercise in Cardiovascular Health Indicators (BREAK001)
28. september 2021 opdateret af: Raphael Mendes Ritti Dias, University of Nove de Julho
Effects of Breaks of Sedentary Behavior With Isometric Exercise in Cardiovascular Health Indicators of Adults
The goal of this study is to analyze the chronic effects of sedentary behavior breaks using the leg extension isometric exercise in the cardiovascular health indicators of healthy adults exposed to prolonged time in the sitting position.
The patients recruited will be randomized into two groups: leg extension isometric training (TIE) and control group (CG).
The TIE group will perform 12 weeks of isometric training.
The CG will be advised not to change their routine activities, especially diet and physical activities.In the pre and post-intervention periods cardiovascular measures will be obtained.

Detaljeret beskrivelse
Long periods in sedentary behavior promote deterioration of vascular function, which is directly associated with the occurence of chronic noncommunicable diseases.
In this context, the execution of interruptions in this behavior (breaks) is recommended.
Studies have shown benefits of isometric training in vascular function, which could be useful to minimize the consequences of time spent in sedentary behavior.
Thus, the goal of this study is to analyze the chronic effects of sedentary behavior breaks using leg extension isometric exercise in the cardiovascular health indicators of adults exposed to prolonged time in the sitting position.
The target population of the study will consist of healthy subjects above 18 years of age of both genders.
All subjects will be submitted to measurements of endothelial function, blood pressure and cardiac autonomic modulation.
After these measurements, the subjects will be randomized into two groups: leg extension isometric training group (TIE) and control group (CG).
After 12 weeks both groups will be submitted to the same measurements from pre-intervention.
