The purpose of this study will be investigation of the effect of high-intensity interval training on mechanism of reduce blood pressure induced apelin in treated hypertension elderly people. The study design will be based on non blinding. Forty five patients will be equally divided and randomized into three groups including high intensity interval training 1 and 2 and control. Inclusion criteria: will be treated hypertension elderly men; no any participant to regular exercise training for 1 year and exclusion criteria: body mass index >28; cardiovascular disease; liver and kidney disease; mental disease; functional limitation( such as osteoarthritis) and cessation of drug use during the study. Protocol of high-intensity interval training number one: including 6 intervals that each interval will be 1.5 minutes at 85-90 % HR reserve and 2 minutes active interval at 50-55%. Other high-intensity interval training including 3 intervals that each interval will be 3.5 minutes at 85-90 % HR reserve and 3.5 minutes active interval at 50-55% that undertaken for 6 weeks. Indicators of nitrate/nitrite, apelin, systolic and diastolic blood pressure will be measured before and after 6 week exercise training.
