Abstract

BACKGROUND:


Physical activity is defined as any sort of body movement that are performed voluntarily by skeletal muscles resulting in energy expenditure. About 31% of the human beings do not engage in physical activity. In the UK, the physical inactivity rate is very high, only 24% of females and 36% of males are involved in physical activity.


OBJECTIVE:


To measure the energy cost of walking in students and faculties and its association with BMI and Physical activity in Khyber Medical University Peshawar.


METHODS:


This Cross-sectional study recruited 346 participants through stratified random sampling to evaluate undergraduates and faculty of Khyber Medical University. After data collection by using the International Physical Activity Questionnaire-Short Form. BMI was obtained and a 100-meter walk was performed by all participants. Data was analyzed in SPSS and descriptive statistics were obtained and associations were correlated.


 


RESULTS:


Out of 346 sample, there were 177(51.2%) male and 169(48.8%) female. A total of 300(86.5%) were with normal BMI, obesity was found in 46(13.3%) of the sample.The sample which performed Vigorous activity per day were 66.95%. 52.7% performed moderate activity and those with low physical activity were only 1.4% of the sample. The Physiological Cost Index was evaluated for normal and overweight categories of sample. The analysis showed non significant results. When Physiological Cost Index was evaluated with undergraduates, postgraduates and faculty. The analysis showed significant results.


 CONCLUSION:


We found the association of energy cost of walking and physical activity( any type of activity) and also its relation with the BMI of an individual performing physical activity. A strong relation existed between cost effective walking, physical activity and BMI. Obesity was correlated in individuals with a low level of physical activity and high expenditure of energy.
