Assessing the usefulness of Heart Rate (HR) monitoring during self-selected intensity exercises

Other Possible Titles

Monitoring self-selected exercise intensity

Self-selected intensity for exercises using Heart Rate monitoring

Introduction

Purpose

The purpose of this study is to assess the importance of heart rate monitoring during self selected intensity exercises. According to many health experts, intensity activities like cycling, dancing, walking, prescribed home exercise and gardening can have important long-term health benefits, such as lowering blood pressure and cholesterol levels and reducing the risk of heart attack, heart disease, stroke and diabetes.

Independent and dependent variables

The independent variable is the heart rate. Whereas the dependent variable is self selected exercise. To reap the benefits of physical fitness, experts advise that you do at least 30 minutes of moderate-intensity activities every day. In numerous researches, the health benefits of physical exercise are quite evident. Improved fitness results from adaptation and improvement of cardiovascular, respiratory, and metabolic function as well as local responses in the muscle groups engaged.

Limitations and delimitations

The major limitation of this study was the number of sample patients with heart failure, if it had been greater the chances of finding association between exercise and monitoring of heart rate. Delimitations are that this study aims to improve something, and usually this objective is defined as the class of objects in the study. It may be a problem case or a group of isolated cases, what these cases then later receive the improvements.

Hypothesis

H0: Heart rate monitoring has significant impact on intensity of exercises.

H1: Heart rate monitoring has no significant impact on intensity of exercises.

Literature Review

People participate in physical exercise to improve general health, performance-related fitness for a particular sport, and/or for recreation and relaxation. Improved fitness results from adaptation and improvement of cardiovascular, respiratory, and metabolic function as well as local responses in the muscle groups engaged. The nature and magnitude of any training effect are influenced by the frequency, duration and intensity of exercise (Weidong et al 2010). The process of determining and controlling appropriate exercise intensity presents a challenge, which has implications related to both physiological changes and to individual compliance within an exercise programme.

Exercise is a single acute bout of bodily exertion or muscular activity that requires an expenditure of energy above resting level and generally planned and structured to improve or maintain one or more components of physical fitness. The term 'physical activity' generally connotes movement in which the goal (often to sustain daily living or recreation) is different from physical fitness, but which also requires the expenditure of energy and often provides health-related benefits. For instance, walking to school or work is physical activity; walking around a track at a predetermined heart rate is exercise (Tapia et al 2007). However, from a physiological standpoint both bring about changes (both acute and chronic). Therefore, the terms exercise and physical activity are used interchangeably. Where the amount of exercise can actually be measured, the terms workload and work rate may also be used. Exercise disrupts the homeostatic state or ...
