Impact of Virtual Capacity on Age, Chest Circumference and Pulse Rate Assignment | Get Paper Help

Abstract

The main purpose of this was to determine how certain variables like height, chest circumference and resting pulse rate will impact a person’s vital lung capacity. A Phipps and bird 9-l spirometer was used to measure the vital capacity of the 67 students from the principles of biology class at Slippery Rock University. Vital capacity was impacted by height and chest circumference, but was not impacted by the resting pulse rate

Introduction

Vital capacity (VC) is defined as the maximum volume of air a person can exhale after a maximum amount of air that has be inhaled. Furthermore, It is the total of tidal volume plus the inspiratory reserve volume (IRV), and expiratory reserve volume (ERV) (David and sharma 2009). The spirometer was first invented by John Hutchison in 1846 (Bowen and Bryon 1923). The spirometer is used mainly to measure how much air your lungs utilize. It is often used by doctors mostly after surgery (james 200). Individuals Vital capacity can be affected by factors like cold, age, lung disease such as copd.

In this experiment we examined how vital capacity can be affected by one’s age, gender and the amount of physical activities they performed. The purpose of this study was to see if there was a relationship between VC and other factors like height, chest circumference and radial resting pulse rate among the 67 students at Slippery Rock University. It was hypothesized that the factors measured would impact vital capacity.

Materials and methods

In this study, Vital Capacity (VC) was measured in a class of 67 students at Slippery Rock University. The VC was calculated in litters using a Phipps and bind 9-l wet spirometer and was replicated 3 times in a seating and standing position respectively. The ages of all 67 students ranged from 18 to 38 and in total there were 50 females and 17 males in the study. Next the averages of VC for both positions were taken by adding results from all 3 replicates and dividing by 3.

Several factors that impacted V.C were measured of which were chest circumference, height, gender and resting pulse rate. A tape measure was used by each student to measure their chest circumference while a meter stick was used to measure their height.  The next thing the student did was to calculate the resting pulse rate after seating and resting for 10 minutes, the student calculated their resting pulse by placing their middle and index fingers of one hand on the radial artery of the other arm and counting the number of pulse during the per minute  using a stopwatch, this was done three times creating a replicates of 3 pulse rate and the average was taken and determined. Lastly the students were told to indicate if they were athletes and if they smoked.

Results

The data set contained many different averages and ranges of the parameters measured. The results constitute of a total of 67 students, of which 50 females and 17 males who participated in the study range in ages 18 to 37. The average vital capacity for the 67 students while standing was 3.2278 versus 3.2051 while seating.  The analysis of data in Table 2 shows average vital capacity for female students standing was 2.8155 and seating was 2.8646, The average vital capacity for males was standing 4.215 and their sitting was 4.2064. it also shows average seating vital capacity for smokers to be versus 234d of non smokers and their standing to be 12a and wax respectively.The Last we see the comprism of athletes and non ato be 235 and x23 while seating and their standing to be 232 and 323

It is learnt from Table-2 that the correlation coefficient between vital capacity and height was 0. 708829 which is athletes high amount. The graph in figure 1 shows that there is a significant positive correlation between height and someone vital capacity. We also see the correlation coefficient between vital capacity and chest circumference was 0.299273 The graph in figure 2 shows that there is also a positive correlation between vital capacity and the chest circumference, in order words the bigger a person chest circumference the higher their vital capacity

Table-1 reveals the correlation coefficient between of vital capacity versus and resting pulse rate was 0. 075097. Compared to the other factors in this experiment the correlation coefficient was the lowest of all three factors. The graph in figure 3 shows that there is no correlation between a person resting pulse rate has nothing to do with their vital capacity.

Discussion

There are several factors that can affect a person’s vital capacity, such has age, height, lung diseases, chest circumference, smoker and level of physical activity. It learnt from table 2 that smokers and nonathletes have a lower vital capacity that their counterparts. In this study,we looked at how height, chest circumference and resting pulse rate can affect a person’s vital capacity. We did find out that height does impact vital capacity in a positive correlation as in figure 1 this might be due to the increase in surface area of one’s lungs in relation to the increase of height. Irzaldy et al (2016) report that the taller a person is the bigger their thorax would be and so because the thorax main component is the lungs taller people will have a higher vital capacity.

The results in Figure 3 shows a scatter plot which is Interpreted as no correlation, meaning that resting pulse rate do not contribute to vital capacity. A study done by summit k Thapa (2016) reported revealed there was not a significant improvement of Vital capacity and Resting pulse rate of selected 15 days adventure sports program
