The effect of music genre on heart rate and blood pressure
By: Kristin Hall
Introduction:
Heart rate measures the speed of the number of times the heart pulses per a unit of time, normally beats per minute (Biology Online, 2011). The number of pulses is based off the number of contractions of the ventricles. This number shows how much blood is flowing through the body, and thus how much hemoglobin and oxygen is being transported. When muscles become active they require more oxygen to function at optimal conditions, so thus there is a high heart rate when exercising. Blood pressure is closely related to heart rate. Blood pressure is the pressure on blood vessels from blood. The pressure will change based on wither or not the heart is contracted or relaxed. Blood pressure is represented by two numbers; the systolic and diastolic pressure. The systolic pressure is when the ventricles just contracted, and the diastolic pressure is the pressure after the ventricles relax (Weedman and Prins, 2014). Music and its …show more content…
In this specific experiment two types of music was chose, classical and heavy metal. Both are very different from each other so the results were obvious from one another. The dependent variable was the heart rate and blood pressure. The experiment was designed so the heart rate and blood pressure would have obvious changes from each other and the basal readings. The experiment was fairly controlled in an attempt to have unskewed answers. Several scenarios were controlled were the volume of the songs and the time exposed to the music. This is essential to control as loud music, regardless of genre could stress the subjects. The environment was also controlled as all the subjects completed the experiment in the same room. Age was also roughly controlled as all subjects in the experiment were college students. The control is necessary to keep the results as close to accurate as
