Lab Assignment

Introduction: In this experiment, cardiovascular fitness is being determined by measuring how long it takes for the test subjects' to return to their resting heart rate. Cardiovascular fitness is the ability to "transport and use oxygen while exercising" (Dale 2015). Cardiovascular fitness utilizes the "heart, lungs, muscles, and blood working together" while exercising (Dale 2015). It is also how well your body can last during moderate to high intensity cardio for long periods of time (Waehner 2016). The hypothesis is that people who exercise for three or more days will return to their resting heart rate much faster than people who only exercise for less than three days.

7. Based on the results of this exercise, which of the following blood pressure readings are significantly above normal, indicating hypertension?

4) Compare and contrast oscillations in heart rate observed at rest (Activity 1), during exercise and recovery exercise (Activity 2). Is the relative magnitude of the oscillations the same? Provide a physiological explanation in your answer.

| Which of the following resting pulse and resting blood pressure results would be typical of a well-conditioned athlete? 72 and 150/90; 48 and 110/80; 66 and 120/95; 84 and 110/75.

Why does Systolic BP increase when the participants start to exercise while diastolic remains constant when compared to standing?

A normal heart rate at rest can range from 60-100 beats per minute (BPM) for adults. Most of the time a

Research Question: What is the effect of practicing aerobic sports on a daily basis, on the recovery heart rate of people?

Person X’s heart and ventilation rate was normal before the test because they had not begun exercising and were at a resting rate. The reason their heart and ventilation

To examine dynamic exercise which is the independent variable of this experiment and obvserve the changes it had on HR, SP, DP, PP and MAP.

The heart rate increases as activity intensity in the body increases. The cause of this increase in heart rate is due to the working tissues in the body increasing their need for oxygen and nutrients. The heart needs to pump faster to supply the tissues with an adequate amount of oxygen and nutrients needed for the muscles (Tortora & Derrickson, 2014, p. 716). During the increase of activity levels in the body and rise of heart rate, blood pressure is additionally effected because of the increased need of oxygen flow to tissues in use and cardiac output directly affects blood flow (Tortora & Derrickson, 2014, p. 741). Therefore the main focus of this report will be discussing the two main concepts of the effects of increased intensity of exercise on heart rate and blood pressure.

HYPTHESIS: If the intensity of exercise is increased over time, then systolic blood pressure, heart rate, and rate of perceived exertion (RPE) should correspondingly increase as well. Once the stimulus (exercise) has been removed, heart rate and systolic blood pressure should gradually return to homeostasis.

The Medical world had many different complex cardiac myocardium information. Medical conditions dealing with the cardiac myocardium and medical tests with using electronical cardio diagrams and the electronic cardio graphs. The information helps with many different connections and functions with patient’s treatment and their progress with their care. My medical knowledge and education with the medical filed as an LPN I have learned many different perspectives and with the complex medical technology. That my patient’s medical diagnostics for their medical conditions. This information is on the heart and the EKG and the ECG structure.

R) Trace or copy Figure 35b (pg 482). Indicate the flow of blood through the heart on the drawing. Use a red pencil for oxygenated blood and a blue pencil for de-oxygenated blood.
