Randomized trial compares aerobic fitness and oxygen-carrying capacity in rural and urban adolescents, suggesting lifestyle improvements are needed.

The study aims to compare VO₂ Max and hemoglobin levels in rural and urban high school students in North Coastal Andhra Pradesh.
Total of 300 students from Srikakulam, Vizianagaram, and Visakhapatnam districts were assessed.
VO₂ Max was measured via standardized step test and hemoglobin through laboratory procedures.
Statistical analyses included mean, standard deviation, and t-test techniques.
Significant differences in VO₂ Max and hemoglobin levels were found between rural and urban students.
Environmental conditions, nutritional habits, and physical activity patterns contribute to variations in fitness.
Findings underscore the need for enhanced health awareness and nutrition programs among adolescents.

Dr. RAMARAJU DEVARAJU (2026) studied this question.
