The present study was conducted to find out the health related physical fitness differences among boys of kandi area. In the present study, the subjects for data collection were drawn from the different government schools of kandi areas of Punjab state. Random sampling technique was used to select the subjects. The sample consisted of one thousand and five hundred seventy five (N=1575) boys of Kandi areas of Punjab state. To measure maximal functional capacity and endurance of the cardio-respiratory system of the subjects, the 9-Minute run test was applied. To evaluate the level of fatness in school age boys, the skinfold fat caliper was used. To assess the abdominal muscular strength and endurance of the subjects, modified sit–ups test was applied. Sit and reach test was used to evaluate the flexibility (extensibility) of the low back and posterior thighs of the subjects. The Analysis of Variance (ANOVA) was applied to find out the significant differences among various age groups/classes of kandi area boys. Scheffe’s post-hoc of test was applied to see the direction and significance of differences where ‘F’ ratio was found significant. The significant differences were observed among various age groups of Kandi area. The class 9th demonstrated significantly better maximal functional capacity & endurance than class 8th whereas class 10th exhibited significantly better on maximal functional capacity & endurance than class 8th and class 9th. Class 8th demonstrated better body composition than class 9th and class 10th. Similarly class 9th demonstrated better on the said variable than class 10th though not significantly. Class 9th exhibited significantly better abdominal muscular strength & endurance than class 8th. Similarly class 10th demonstrated significantly better than class 8th and class 9th on the said variable. Class 9th showed significantly better flexibility (extensibility) of the low back and posterior thighs than class 8th. Similarly class 10th demonstrated significantly better flexibility than class 8th and class 9th.
