Practical Report: Blood Pressure and Lung Function

Introduction

Heart rate is defined as the time that the heart takes in completing the cycle of filling and emptying the chambers in a given time. It is expressed in pulse (a combination of heart contraction and expansion) per minute (Maass & Buck, 2009, 773). Completion of these two activities results in changing the speed of blood pressure and circulation into the body. The pulse of heart of a person in a given time is dependent on multiple sets of variables. Majority of these subjects are independent to the subject, such as temperature, altitude or air quality, time of day or the individual's age (Bill, 2010, 375). Other set of variables are intrinsic to the subject that relate to genetic condition of a person, such as height, gender etc (Dipla & Vrabas, 2010, 17). Past researches show that psychological factors also impact the blood pressure significantly.

The lungs are one of the significant parts of the human body; the core function of the primary purpose of the lungs is to maintain the inhalation and exhalation of air and supply a sublime portion of air to the blood in order to adjoin adequate amount of oxygen for the blood. Moreover, the function of lungs is to remove the carbon dioxide from human body as it hinders the respiratory system. The function of the lungs is performed through the pumping system of two mechanisms. The function of one mechanism is to move a gas and the other mechanism is responsible for maintaining a portion of liquid in the organism. The blood and air are brought together so closely that only approx. 1 µm (10-6 m) of tissue separates them (Cornelissen, 2010, 175). The volume of the pulmonary capillary circulation is 150 ml, but this is spread out over a surface area of approx. 750 sq ft (69.68 sq m) (Najafi, 2011, 106).

Heart stroke volume increases when exercising due to excessive amount of blood in muscle cells. Cardiac output represents the contraction and expansion of heart muscles that involves rapid flow of blood. Physical activity and exercise have a notable impact on the blood circulation and heart pulse rate. Generally, normal resting heart rate is between 50 and 95 beats per minute (Najafi, 2011, 107). When a person is born, high heart rate is observed because the body's activity. Heart rate varies throughout the day and night in response to various stimuli, so its measurement is highly variable (Maass & Buck, 2009, 773). The maximum frequency that can reach the heart before a higher exercise depends on the age and body weight of the person (Cornelissen, 2010, 54).

Aims

The main objective of this research is to examine the relationship between heart rate and pulse rate of male and female.

Method

Twenty four students were included as participants in the study. Mean age of the students stood at 22 years ± 2.54 years, body mass of 73 ± 12.77kg, and average height of 1.74metres ± ...
