HEART AND BREATHING RATE

Heart and Breathing Rate

Heart and Breathing Rate

Introduction

This investigation is to show the respiratory and circulatory systems in deeper meaning. It also explains the reasons for why breathing and heart rate becomes higher during physical activity, and if there are any differences between female and males.

This experiment shows the biological principles, and how to record and produce data of a quality standard.

Air goes into the alveoli when we breathe in. This lets the veins around the alveoli drop of their carbon dioxide and pick up oxygen. The oxygenated blood travels around the body and drops of oxygen to cells and picks up carbon dioxide. It travels back through the veins through to the heart and then to the lungs again and repeats the progress. Cells use oxygen and produce carbon dioxide when being more active.

The subjects were moving to make their cells become more active. The reason for this was to find how this affected the heart and breathing rate. The subjects were separated into male and female to look for a difference between the genders breathing and heart rate.

Research Question

1. The rate of heartbeat decreases as physical activity increases.

2. The rate of breathing increases as physical activity increases.

Data Analysis

We use SPSS 16 to analyze the data set of Horse Heart rate and Breathing rate before and after exercise.

a. Multiple modes exist. The smallest value is shown

The mean of Mean HR before exercise is 53.25 and st. deviation is 6.57 this shows variation is present in Mean HR before exercise dataset or heart beat is quite affected by exercise.

The mean of Mean BR before exercise is 15.45 and st. deviation is 3.06 this shows variation is present in Mean BR before exercise dataset or breathing rate is quite effected by exercise.

The mean of Mean HR after exercise is 171.60 and st. deviation is 15.4 this shows variation is present in Mean HR after exercise dataset or heart beat is quite affected by exercise.

The mean of Mean BR after exercise is 89.35 and st. deviation is 5.8 this shows variation is present in Mean BR after exercise dataset or breathing rate is quite effected by exercise.

The shape of above histogram is negatively skewed.

The shape of above histogram is negatively skewed.

From above histogram we can observed a multimodal shape of data.

The shape of above histogram is said to be symmetric.

From above cluster bar charts of Mean Heart rate before and after exercise we observed that heart rate is affected by exercise and it increases after exercise.

From above cluster bar charts of Mean Breathing rate before and after exercise we observed that breathing rate is affected by exercise and it increases after exercise.

Discussion

The heart rate is basically the amount of times the heart beats per minute. An adult usually has a normal resting heart rate of about 60 to 100 beats per minute, or bpm. A well-trained athlete's resting heart rate is around 40 to 60 beats per ...
