Abstract
Introduction: The aim of this study was to investigate the effect of selected two types of short and long term high-intensity intermittent exercises on serum vascular endothelial growth factor (VEGF) of active older men.
Methodology: In order to do that 10 active older men with an average age of 63±4/6 years, height 1/71 ± 0/05 m, and a weight of 76/7 ± 7/5 kg, were selected as the subjects of this study. Lack of chronic diseases (cardiovascular, liver, kidney and blood), smoking and drugs, lack of musculoskeletal injuries, lack of blood pressure and cardiovascular medications were considered in the selection of subjects. The two exercise protocols had equal durations. Short and long term activities included 12 min running respectively with 20 s and 3 min intervals (85% of maximum heart rate) with the work to rest ratio of 1:1. Blood samples were gathered before and immediately after the exercise. All subjects performed both protocols on the same term and with 7 days interval for washout. For studying the inter group changes of VEGF-A the repeated measures and for comparing the data of two exercise methods the independent t test were used.
Results: The long term high-intensity intermittent exercise led to increase in serum VEGF-A immediately after exercise. After short interval exercise the VEGF-A level immediately decreased which was its acute response.
Discussion: There was no significant difference between two types of long and short-term high intensity intermittent exercises on serum VEGF-A level of active older men before and immediately after the exercise.
