The goal of this research is to examine the physiological fitness of schoolchildren in Manipur's hill and valley districts. Four physiological variables, namely cardio respiratory endurance, force ventilator capacity, VO₂Max, and mean arterial blood pressure, are tested on a total of 200 grade X males aged 14 to 18 years old, divided into two groups: hilly school (N=100) and valley school (N=100). By analyzing the data using the statistical software SPSS, it was discovered that hilly school males are older, heavier, and shorter than valley school boys. Their average age and weight were 16.6 and 16.4 years old, respectively, and 47 and 45 kg. Their average height was 157.19 and 158.57 cm, with a range of 133-167 cm and 130.00-175.00 cm. Physiological variables like cardio respiratory endurance (Tuttle pulse ratio), force ventilator capacity (using peak flow meter), VO₂Max (one mile run/walk Cooper test) and mean arterial blood (using sphygmomanometer) of Government hilly region schools findings were 74.6045±3.71, 405.3±9.36, 38.8870±3.11 and 93.93±3.34 respectively and Government valley region schools findings were 70.0802±3.25, 389.7±10.95, 34.5960±1.81 and 94.4033±2.15 respectively.  The comparison of these scores by using statistical technique found that hilly school boys were more fit than the valley school boys. The disparities between highland school and valley school boys in Manipur state were statistically significant in all body metrics and physiological fitness parameters at the (p<0.05) level of significance. The findings show that hilly school boys outperform valley school boys in terms of physiological fitness.
