A study on oxygen dependent fitness (aerobic capacity) in pre-collegiate boys of North Karnataka region

Abstract

Background: Aerobic capacity (VO2 max) measures the higher limit of energy content in the muscles. In general, genetics of an individual decides the higher limit of the muscle, but physical training can improve it by up to 20% as compared to nontrained individuals. Aims and Objectives: To evaluate oxygen dependent fitness (aerobic capacity) in pre-collegiate boys (age group of 16-18 years) of North Karnataka region. Materials and Methods: A total of 87 young adolescent healthy pre-collegiate boys volunteered for this study. Physical anthropometric parameters such as body surface area (BSA), body mass index (BMI), and body fat percentage (BF%); physiological parameters such as systolic and diastolic blood pressure; fitness tests such as physical fitness index (PFI) and aerobic capacity (VO2 max) were measured. Correlation analysis and Z-test was used to obtain the data. Results: Physical anthropometric parameters of the subjects were found within normal range. Statistically significant exercise-induced rise in blood pressure was observed in Harvard step test. PFI correlated with aerobic capacity. Aerobic capacity correlated with BSA and did not correlate with BF% and BMI. Conclusion: The PFI was in good category, normal physiological response to exercise, and PFI correlated with aerobic capacity (VO2 max). Aerobic capacity was found within the normal range in pre-collegiate boys of age 16-18 years in the study area. Ideal BMI may not be possible in this age group.
