The purpose of the study is to compared different modes of exercise for eliciting post-exercise hypotension. The study will randomize 10 healthy participants to 30 minutes of either aerobic exercise, isometric exercise, stretching, or rest (control). Blood pressure and heart rate will be assessed before and for one hour post-exercise.
The purpose is to compare different modes of exercise (aerobic vs. isometric vs. static stretching) for reducing blood pressure post-exercise. : Using a randomized crossover design, 5 male and 5 female (n=10) normotensive university students will participate in four different exercise sessions for 30 minutes: aerobic (cycle ergometer at 70% of VO2max), isometric (alternating wall-sit for 70% of max, and handgrip dynamometer at 30% of max for 2 minutes), stretching (targeting the larger muscle groups of the body), and control (rest). Participants' blood pressure and heart rate will be measured before each exercise session and monitored for 60 minutes afterwards to analyze the post-exercise hypotensive response.
