Influência do equipamento ondas curtas na produção de estresse oxidativo e capacidade antioxidante

Resumo (EN)

Objective – Most studies on production of oxidative stress has been returned to the practice of aerobic exercises and relations with various pathologies. A detailed analysis of individuals subjected to electromagnetic radiation produced by short wave equipment will provide great contribution to the understanding of oxidative stress and electromagnetic radiation. The purpose of this study is to assess the influence of electromagnetic field emitted by short-wave equipment in the production of oxidative stress and antioxidant capacity of each individual. Methods – For this, 15 university individuals were selected, regardless of gender, from 18 to 25 years old, underwent daily sessions in shortwave equipment continued for 15 minutes. Questionnaire was applied, and before and after the 10 sessions collected a sample of venous blood for analysis and comparison of levels of Malondialdehyde (MDA) and Total Equivalente Antioxidant Capacity (TEAC). Results – In subjects in general there was an increase in average MDA, but in subjects alcohol was a significant increase with P = 0.0432. Those in their diet that included vegetables and legumes, fruits, nuts and margarine, there was significant increase in TEAC with P = 0.0328, P = 0.0360, P = 0.0275, respectively. In individuals who had BMI between 24.8 - 28.0 occurred with a significant increase of TEAC P = 0.0316. Conclusions – It was concluded that the short waves do not interfere with the production of oxidative stress due to the immediate action of antioxidant capacity.
