Physiological cost index of different body mass index and age of an individual

Abstract

Background:The energy expenditure is the amount of energy (or calories) that a person needs to carry out a physical function such as breathing, circulating blood, digesting food, or a physical movement. The method for estimating the energy cost using measurement of heart rate (HR) is the physiological cost index (PCI). Aims and Objective: The aim of this study is to measure and correlate the relationship of energy expenditure of a normal healthy individual with different body mass index (BMI) and age. Materials and Methods: A total of 115 participants (59 males and 56 females) were included in this study. Written consent form was obtained. Before exercise testing, each participant's was measured that BMI was the standard formula (kg/m

Effect of Aerobic Exercise Training on Energy Expenditure by Physiological Cost Index in Obese Individuals

“…It is observed that as the BMI increases, the physiological cost index increases, thus concluding more energy expenditure. (2) Hence our study is undertaken to improve the physiological cost index of obese individuals by giving aerobic exercise.…”

“…Energy expenditure varies with both among individual and within the same person depending on the circumstance, body weight, walking speed, surface texture and gradient. (2) The PCI is an easy to use valid and reliable measure of energy expenditure and it is recommended as a useful tool for physiotherapist in the assessment and evaluation of functional performance. The PCI was founded on the principle that Heart rate (HR) and walking speed are linearly related to VO2 at the submaximal levels of exercise.…”

“…The PCI was introduced by MacGregor who recognized a simple, functional, non-invasive method of measuring the physiological cost of walking that could be equally applied in domiciliary and clinical environments. (2) He also suggested that PCI is one of the good indicators of energy cost. Therefore, PCI is an effective tool used to measure the energy expenditure during walking.…”

“…Therefore, PCI is an effective tool used to measure the energy expenditure during walking. (2) PCI is calculated by dividing the difference (HRwalking -HRbaseline) by walking speed. It thereby yields an outcome that is expressed in beats per meter.…”

Effect of Aerobic Versus Anaerobic Exercise on Energy Expenditure in Young Healthy Individuals

“…Energy is expended by individuals engaging in physical activity 1 . The energy expenditure is the amount of energy or calories that a person needs to carry out a physical function such as breathing, circulating blood, digesting food or a physical movement 3 . Energy expenditure index based on heart rate and walking speed has been termed Physiological Cost Index (PCI) by McGregor.…”
