Set Volume of Optimal Resistance Exercise to Generate Hypotension

Study Overview
=================
Brief Summary
-----------------
This study evaluates the volume of optimal resistance exercise to generate postexercise hypotension after performing a single exercise in hypertensive elderly subjects. 20 subjects will perform 1 control session and 3 resistance training sessions with different volume: 3, 6 and 9 sets
