This study is relevant because it gives more insight on the body’s ability to adapt to stress/ exercise or how the cardiovascular and respiratory systems respond to increase in metabolic activity. When stimulus such as an exercise is activated, almost all the organs and systems in the body are affected. The body is designed to be able to handle such requirements. The cardiovascular system is one of the systems involved in the body’s regulation to various stimuli (Na D et al, 2005). It is made up of the hearts and blood vessels. It is in charge of supplying oxygen and nutrients to the cells in the body. When the body is undergoing a phase of exercise, the cardiovascular system has to work more effective and faster to meet increased metabolic activity. There is always a decrease in heart rate, breath rate and blood pressure experienced by the cardiovascular system due to exercise. Higher blood pressure tends to raise risk for strokes and heart attacks (www.nhlbi.Com, 2011). Athletes are at advantage because they mostly have a low blood pressure that cannot put them at risk. The hypothesis for this practical is that heart rate, breath rate and blood pressure for conditioned will be lower than unconditioned.
Subjects - Twenty six full time students from Medipathways volunteered to do the exercise for this study. These participants included 16 males and 10 females and their age ranges from 19 – 26, signed the par-q. There were 11 conditioned and 5 unconditioned males and 5 conditioned and 5 unconditioned females. A stethoscope, sphygmomanometer and an RPE chart were the equipments used to conduct this experiment. The stethoscope and the sphygmomanometer were used to measure blood pressure and the RPE chart was used to measure the intensity of the exercise.
Heart rate measurement - The heart rate was measured on the radial pulse by hand and it was taken for 15 seconds and the answer we got was multiplied by four to get the heart rate for one minute and it was recorded after 0, 5, 10 and 15 minutes. 0 and 5 minutes were the resting stage before exercise, 10 minutes was immediately after exercise stage and 15 minutes was the resting stage after exercise.
Blood pressure measurement - The blood pressure was measured using the sphygmomanometer; it was taken after the heart rate at the same time interval. The systolic pressure and diastolic pressure were measured.
Breathing rate measurement - The breathing rate was also measured, it was taken by counting the number of times the participant inhaled and exhaled which is considered to be one breath.
The experimental procedure was made up of four sessions performed in three hours. The participants were asked to sit comfortably and after 5-10 minutes, their heart rate, blood pressure, breathing rate and rate of perceived exertion were measured. After 5 minutes of further resting, the measurements were repeated. The exercise stimulus began immediately after the values...
