Cardiovascular Activity And How it Influences the body.
Introduction:
Cardiovascular fitness is a form of aerobic fitness (Neporent and Egan 1997). There are many different ways of evaluating the amount of oxygen used during cardiovascular fitness and one the methods involved is called VO2 Max. VO2 Max is the maximum amount of oxygen that the body can hold. (Simon and Levisohm 1987). Cardiovascular fitness helps to improve a healthy lifestyle.
For this experiment the null hypothesis is that the intensity of the step rate test (High and Low) has no effect on the persons’ heart rate

The first participant measured her pulse rate for 30 seconds before starting the exercise. Her pulse rate was calculated to determine the number of beats per minute. She then stepped on the platform (up and down) and continued at a slow pace for 3 minutes. After three minutes of the exercise, she measured her pulse rate every minute to determine her recovery time. This process was repeated until her pulse rate returned to normal. The amount of time taken in seconds for her pulse rate to return to normal is the recovery time. The number of steps taken in a minute remained constant for both …show more content…
The average pulse rate after the test was 27 heart beats per minute. The SEM of the pulse rate before the test is +/-3.3bpm, while the SEM after the test is +/-4.5bpm. In test two the participant did the step test at a faster pace, also looking at the results from figure 2, we can see that the pulse rate (measured in beats per minute) before the step test is much lower than the pulse rate of the individual after the step test at a faster pace. An increase can be observed looking at the average which is 44 heart beats per minute after the step test. The SEM of the pulse rate before the test is +/-4.2bpm, while the SEM after the test is +/-10.1bpm.
The mean recovery time (which is measured in minutes) is also compared. The slow steppers had an average recovery time of 2.3 +/-0.42, whereas the fast steppers had an average recovery time of 3.75 +/-0.44. The difference in the recovery rate between the two groups is
This article discusses in detail, the various benefits of cardiovascular exercise for overall cardiovascular health.
The Queens College/McArdle Step Test, the Rockport One Mile Walk Test, and the 1.5 Mile Run Test are three different field tests that were performed in this lab that were used to measure and predict an individual’s aerobic capacity. The measurement of aerobic capacity, or VO2 max, is a valid way to assess an individual’s cardiorespiratory fitness level. VO2 max refers to the maximal amount of oxygen an individual utilizes during intensive exercise. A higher VO2 max demonstrates a more efficient cardiorespiratory system as an individual with a higher VO2 max can sustain a higher intensity for a longer
This lab experiment was conducted in a Texas Woman’s University exercise physiology lab room, on September 20, 2013. It consisted of two main participants: A trained participant (Male; 30 years old; 72 in. tall; 82.9 kg) and an untrained participant (Female; 20 years old; 65 in. tall; 75 kg). They were selected by my Prof. April Hartman to participate because they were best qualified to conduct the study in our class. Both participants were assigned to carry out the same experimental task. The Bruce Protocol (graded test) on a treadmill (mode of exercise) was used to conduct the VO2max test. The materials needed were: 1 metabolic cart (with computers); 2 mouthpieces; 1 nose clip; 1 treadmill; 1 RPE scale; 1 timer; pen; paper; and a HR monitor.
First I will record the pulse rate of the subject after performing physical activity which will give me the subject’s pulse rate after physical activity without the effect on the energy drink. After which I will make the subject perform the same but with different volumes of energy drink

In addition, each of the test subjects had high resting heart rate. On average, resting heart rate should be approximately
There are many tools to assess functional exercise capacity most of which provide good information about body system. The most popular clinical exercise tests are stair climbing, a 6MWT, a shuttle-walk test, detection of exercise-induced asthma, a cardiac stress test and a cardiopulmonary exercise test) (ATS, 2002). In the past, the functional exercise capacity was assessed by asking patients “How many flights of stairs can you climb or how many blocks can you walk?”; but, this assessment was a subjective measurement. In addition, the first objective tool was in 1960s which was 12 minute walking test; however, it was so exhausting for patients. As a result from that, a 6 minute walking test (6MWT) was found to be used as an objective measurement tool for functional exercise capacity in patients with mild or moderate respiratory diseases and cardiac diseases (ATS, 2002). Many studies have concluded that 6MWT is inexpensive test and“… it is easy to administer, better tolerated, and more reflective of activities of daily living than the other walk tests” (ATS, 2002). Therefore, this essay will describe the 6MWT and comment on administration, application, reliability and validity based on the literature reviews.
This experiment made use of a single male subject who was 20 years old, with a height of 190.5 cm and weight of 104 kg. The study consisted of obtaining heart rates after the following conditions 1) after one minute in the supine position, 2) immediately after moving to a sitting position, 3) one minute after moving into a sitting position, 4) immediately after moving to a standing position, 3) one m...
Introduction: In year 10, biology, we have been studying the heart: the functions of the heart, the parts of the heart (ventricle, atrium) and heart problems. Besides that we have been studying the heart rate of humans. We were asked to create an experiment to see what affects heart rate. We discovered that diet, stress, cholesterol level, excitement, mass, age, temperature and exercise affected the heart. Diet and exercise were the only 2 doable and so my partner and I chose exercise. We determined that as the intensity of an exercise increased so did the heart rate of the person performing it.
The female subject’s average power was 106 kg-m/sec. The average power output male were classified as good and female subjects were classified as average according to the Magaria- Kalamen classification chart. The mean power output for the male subjects was higher than the female subjects. Males have more Type II or fast twitch fibers, which are better for fast and powerful movements like the power test or any quick pace activity. Females tend to have more Type I or slow twitch fibers which are better for endurance exercises, such as running or biking. The first time running up the stairs was the slowest time for most of the subjects. This was probably because the subjects’ had to adapt to the task. The second trial was the fastest because the subjects’ were familiar with the task. The third trial for most of the subjects was slower than the second trial but faster than the first trial, most likely due to being tired. An error that could have occurred was the reaction time of the timer. The timer started timing when they saw the subject’s foot hit the first step. However, the time was not as accurate as possible because there is a delayed response before the timer hits the start button and the foot touching the step at a fast speed. Another error was that the stairs were not the standard set for the test. The vertical distance of the stairs is supposed to be 1.8 meters, but
The two major things that will help an athlete while measuring the cardiovascular drift are progression and hydration levels. The heart rate of an athlete working hard during a workout should be no more than their maximum heart rate which is found by, if you’re a female take 226-age, if you’re a male take 220-age. If while doing a workout the maximum heart rate is exceeded by too much it may be necessary to take a break or slow down greatly. This may also help with traking the hydration of an athlete. If an athlete stays hydrated their core temperature will stay regulated which means they won’t sweat as much, which also means the heart won’t be under as much stress while transporting the oxygenated blood throughout the body to the
This test was performed on a 31-year-old untrained female. The subject was 31 weeks pregnant at the time the test was performed. This subject will be referred to as subject one for the remainder of this report. Subject one’s height was measured using a stadiometer and her weight was measured using a tenita scale. Her height was reported to be 163.3 cm and her weight was reported to be 96 kg. Subject one was then placed on the cycle ergometer and the seat height was adjusted. Her knee flexion was measured using a goniometer and was 20° flexed. Subject one reported her resting heart rate to be 100 beats per minute (bpm) and her resting blood pressure to be 120/80 mmHg. These values of resting heart rate and resting blood pressure were given by subject one and not measured. Subject one was instructed to begin a 4-minute warm-up, pedaling at approximately 50 revolutions per minute (rpm) with no resistance. Following the warm-up, the 6-minute exercise phase began and subject one was instructed to maintain a 50 rpm pedaling rate for the duration of the test. Based on the training level reported by subject one resistance was set using a weight of 1 kilopond. The heart rate was reported by the first technician and was instructed to report heart rate during the last 15 seconds of every minute by the second technician. The heart rate was then multiplied by 4 to result in an overall heart rate of beats per minute. These values can
To complete the data sheet I used to finalize my hypothesis, I was given a sheet that had a survey and different activities I had to perform and check my pulse while doing them. The survey consists of questions that ask if I smoke, exercise, drink coffee, drink soda, drink Energy drinks, eat breakfast, and eat dinner. The activities included resting, walking, riding an excursive bike, drinking water, drinking soda, drinking coffee, taking an exam, driving through traffic, eating breakfast, eating dinner, and awakening from sleep. I had to record my pulse before, during, five minutes after, and...
The materials used: one wristwatch (with second hand), two variably indifferent humans (one male, one female), and a standard staircase at CCC. The method was simple: two test subjects were exposed to two trials involving one minute of physical activity and x minutes needed for the recovery of the heart rate. Before the experiment began, each subject's resting heart rate was taken. This would become the controlled variable. Next, each subject ran up one set of stairs at CCC, one stair at a time, for one minute. After one minute of activity, the subjects stopped and began taking his or her heart rate.
The purpose of this experiment was to gather data on how the amount of time spent active impacts the speed of heart rate in beats per minute. The hypothesis stated that if the amount of time active is lengthened then the speed of the heart rate is expected to rise because when one is active, the cells of the body are using the oxygen quickly. The heart then needs to speed up in order to maintain homeostasis by rapidly providing oxygen to the working cells. The hypothesis is accepted because the data collected supports the initial prediction. There is a relationship between the amount of time spent active and the speed of heart rate: as the amount of time spent active rose, the data displayed that the speed that the heart was beating at had also increased. This relationship is visible in the data since the average resting heart rate was 79 beats per minutes, while the results show that the average heart rate after taking part in 30 seconds of activity had risen to 165 beats per minute, which is a significantly larger amount of beats per minute compared to the resting heart rate. Furthermore, the average heart rates after 10 and 20 seconds of activity were 124 and 152 beats per minute, and both of which are higher than the original average resting heartbeat of 79.
