ABSTRACT
Introduction: Energy is expended by individuals engaging in physical activity. It can be calculated after performing aerobic or anaerobic exercise. Energy expenditure index based on heart rate and walking speed has been termed Physiological Cost Index (PCI) by McGregor. The 6 Minute Walk Test is sub-maximal test for assessing energy expenditure. Need of study is to find effect of aerobic and anaerobic exercise on energy expenditure and compare post exercise effect so, that it could be given to any individual for physical fitness in near future according to ones need.
Method: Interventional study, convenient sampling, sample size of 36 subjects. Inclusion criteria: 18-25 years both male and female having BMI (18.5 -24.9 kg/m2). Exclusion criteria: any cardio-respiratory diseases, neurological or orthopedic conditions, not willing to participate. Pre intervention: PCI of subjects assessed by 6mwt and values were put in McGregor’s equation. Subjects were randomly divided into aerobic and anaerobic groups. The exercise protocol was of 4 weeks, 5days/week. Post intervention PCI was calculated.
Results: Statistical analysis was done by using SPPS version 16, keeping the level of significance 5%. Paired t-test was applied for within group analysis and unpaired t-test applied for between group comparison. Within group analysis showed statistically significant improvement in PCI values (p<0.05). Between group analysis showed higher improvement in anaerobic exercise group in comparison to aerobic exercise group.
Conclusion: Present study concluded that 4 weeks of aerobic and anaerobic exercise showed improvement on physiological cost index but higher improvement was seen in anaerobic exercise group.
Key words: aerobic, anaerobic, energy expenditure, healthy individuals.
