Physiological and hormonal effects of concurrent training in the decrease of sarcopenia in elderly – a literature review

Abstract

Introduction: Sarcopenia is characterized by a gradual decrease in muscle mass by aging, altering musculoskeletal functionality and physical performance related to human movement. In addition, other disorders are identified: increased oxidative stress and intramuscular adipocytes, decreased protein synthesis, systemic changes and neuromuscular integrity. The incidence in Brazil varies from 5 to 32% and this disease is classified as mild, moderate and severe. Our objective was to identify the physiological and hormonal effects of concurrent training in these elderly and to verify the effectiveness of this training. Methods: All processes carried out followed the principles of the Research Ethics Committee of FHO for bibliographic review research, registered under the number 047/2018 and were developed based on studies found in the platforms Scielo, PubMed and Google Scholar, using the following nomenclatures: "sarcopenia", "elderly" and "concurrent training", "physiological effects" and "hormones" and then selecting only studies relevant to the research theme. Development: Physical training is essential and acts as an adjunct or primary element in the treatment of sarcopenia, depending on whether there is pharmacological intervention or not. One of the methodologies of physical training used in this population is concurrent training - the combination of resistance exercises and aerobic exercises, dynamic and interval, promoting several positive physiological adaptations for this public. Conclusion: Concurrent training is positive in combating sarcopenia and its causes, allowing the patient a collection of morphological, physiological and hormonal benefits that will allow increased quality of life and social self-esteem.
