Background and Objective: Cardio-respiratory fitness refers to the ability of the circulatory and respiratory systems to supply oxygen to skeletal muscles during sustained physical activity. In the present study, the Cardio-Respiratory Fitness in Healthy Medical Students of Gulbarga District was investigated. Materials and Methods: The present work was conducted in the Dept. Of Physiology, M R Medical College, Gulbarga after the institutional ethical clearance. In this study, 50 healthy randomly selected students from medical college belongs to same socioeconomic status were included. Exercise was performed and data were recorded using automatic computerized treadmill. Lung Function Tests was performed using computerized vitalography. The data were analysed by paired't' test followed by one-way ANOVA. P value less than 0.05 was the level of significance. Results: The result reflects a Significant increase (p<0.001) in both pre and post exercise changes and a negative correlation(r= 0.048, p=0.05) between BMI and PFI score was observed. A significant increase (t=5.16, p<0.001) of exercise induced rise in SBP and no significant difference between pre and post exercise DBP was found. A non-significant change of vital capacity between pre and post exercise and changes of reduction of FEV1 (%) is found to be statistically significant (p<0.05). Conclusion:The percent recovery of heart rate in medical students reflects a better cardiovascular efficiency.
Background and Objective: Low physical activity and cardio-respiratory fitness are recognized as important causes of morbidity and mortality. In the present study, the pre and post-exercise changes in cardio-pulmonary functions in healthy school children of Gulbarga district were investigated. Materials and Methods: The present work was conducted after the institutional ethical clearance. In this study, 50 male students of school aged between 9-11years who are apparently healthy and who were born and brought up in Gulbarga district (Karnataka) with the same socioeconomic status were included. Children with poor nutritional status were excluded from study. Exercise was performed and data were recorded by automatic computerized treadmill. Lung Function Tests and data were recorded by using computerized vitalography. The data were analysed using one-way ANOVA. P value less than 0.05 was the level of significance. Results: The result reflects a Significant increase (p<0.001) in both pre and post exercise changes and a negative correlation(r= 0.048, p=0.05) between Body Mass Index (BMI) and Physical Fitness Index (PFI) score was observed. A significant increase (t=5.16, p<0.001) of exercise induced rise in SBP of school children and no significant difference between pre and post exercise Diastolic Blood Pressure (DBP) in school children was found. A non-significant change of vital capacity between pre and post exercise and changes of reduction of Forced Expiratory Volume in one second (FEV 1 ) (%) is found to be statistically significant (p<0.05). Conclusion:The percent recovery of heart rate in school children reflects a better cardiovascular efficiency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
