Methods of analysis: Andrea is a 35 year old female who regularly takes part in cardiovascular exercise. She has recorded her beats per minute (BPM) and blood pressure before, during and after performing exercise with a heart rate monitor and a sphygmomanometer. She completed this experiment during a spin class within a controlled environment and on a fixed spin bike. Findings: BPM Before exercise 96 Average heart rate during exercise 142 Maximum heart rate during exercise 174 1 minute after…

Hypothesis: If subjects stretch for three five-minute intervals, then their individual blood pressures will be affected and increase because the movement and use of muscles is also being increased. Results: As shown in Table 1, the blood pressures for each subject varied. Isabella’s blood pressure started out high, with her systolic rates remaining within ten points of each other, and her diastolic rates within 12 points of each other. Her beginning blood pressure was 131/91 and after five…

Summary Magnuson and Enright article “The Church as a Forgiving Community: An Initial Model characterizes how forgiveness portrays a major impact in the lives of families, community, and churches all over the universe. The role of forgiveness can be demonstrated by showing compassion to anyone who has acted unfairly. The Bible tells us in Ephesians 4: 32 that we ought to forgive each other, even as God for Christ’s sake hath forgiven us. In this article, Magnuson and Enright (2008)…

Professor Bearing’s Journey Through Cancer In the story “Wit “by Margaret Edson, the author depicts how a professor by the name Vivian Bearing was brilliant, cold hearted and then she became filled with kindness. Professor Bearing was a tough love teacher; she doesn’t really care about the students and their struggles. Her main fervor is for 17th Century poetry, especially the complicated Holy Sonnets of John Donne; well at least at the beginning of the play. In the latter half of the story…

POSTURAL = position of the body ORTHOSTATIC = relating to or caused by an upright posture TACHYCARDIA = increased heart rate SYNDROME = a combination of symptoms Normally, when a person stands up, the heart rate increases by 10 beats per minute or less. With POTS, the increase is often far greater - usually 30 beats per minute or more. Postural orthostatic tachycardia syndrome is a condition in which a change from the supine position to an upright position causes an abnormally large increase…

Materials and Methods: To be more specific, the following procedure was performed. For the palpation of superficial pulse points, a pulse is easily felt when a superficial artery is pressed against firm tissue such as two pointer fingers. It is not advised to use a thumb, as it has its own strong pulse. The common carotid artery is the first pulse felt. It is on the left side of your neck under your throat near the Adam’s apple and/or upper trachea (for females). Another artery that is felt is…

I want to get a 46 for the pacer test. I chose these two areas to work on because these are my weak points in the fitness test. I want to increase my endurance because I am going to join Track again this year and my goal for the pacer would help me become better at Track because I want to be in 1st-3rd place in the 100-meter dash. My long-term effect is I will reduce the risk of heart disease because endurance will make my heart healthier. I believe the cardiovascular strength that is tested in…

Purpose: Does the heart rate of a student rise more when the student is resting or exercising? It would be obvious that yes, a student’s heart rate would probably rise if they are exercising rather than resting. The data that has been taken down and tested have proven that statement to be true. Background Research: The background research that I have found that besides the difference between exercising and resting, age also has to do with the heart’s rate. The older a person gets the less…

Abstract: Our experiment tests how body positions and body movements affect heart rate. We used 4 different subjects and 3 different trials including our control. For our hypothesis, we theorized that the more movements that a person does, the higher their heart rate will be. After doing this experiment, we found that the more movements and exercises your body does, the more increased your heart rate will become. There could be possible sources of error like any experiments, so this data is the…
