Nowndays the decrease of physical fitness level about children and teenagers is clearly observedin many countries.One of the suggested method for increasing physical fitness about childrenand teenagers is the active transport to school such as walking and bicycling. The recentfindings are indicated that children and teenagers who to school by bicycle or walking havemore physical fitness than children and teenagers who go to school by other vehicles such ascar. We considered randomly 120 students of high school of the east of Mazandaran provinceon 3 groups of 40 students between 15-17 years old (bicycling; walking and motorist). Themeasurement method of physical fitness factors and the performed field tests are used aerobicpower measurement by 1 mile test running; performance strength by sargent jump; endurancemuscle by 1 min test of sit-ups; agility by illinus test; and flexibility by sit and reach test. Foraverage comparison; it is used t-test on independent group between groups and statistic analysis.Average comparison on active and inactive transfer groups is observed in table1.The finding of this research (table 1) are indicated that the teenagers who o to school by bicyclehave more aerobic power; endurance muscle and flexibility than walking group and inactivetransfer. Although; there was no difference (α≤0/05) in agility and muscle strength testsbetween groups. However; in many factors; walking group was better than passive transport(motorcycle; car; bus; train) but there was no difference in 2 groups. (α≤0/05) According to thisthat there was not difference between groups to the rate of sport activities of subjects out oftransfer time to school; then it can result than the transfer to school by bicycle have a majorshare for physical fitness factors. Then; according to above finding; we can suggest bicyclingsport as an active transfer method observance of safety points.
