The main objective of performing this research was studying the effect of execution a period of aerobic activities program upon dynamic and static balance in nonathletic elementary male students. 30 elementary students enjoyed general healthiness who participated in the research, have been classified to control and experimental group. (Age = 12/3± 0/46)(Weight = 53/8 ± 6/413kg)(Length = 152/26 ± 5/930). A pretest of Sharpened Romberg Test¹ (static balance with open and close eye) and SEBT² (dynamic balance) was been carried out on 2 groups, a day before start trainings. Experimental group get involved in performing a period of aerobic exercise program on treadmill for six weeks (3 sessions in every week). During this period the control group was asked to keep their daily activities. After completion the exercises, after test was carried out on experimental and control group in the same environment. Descriptive statistics were applied for calculation the mean and standard deviation of the data and orderly, independent t and dependent t were applied for determining the difference between pretest, after test and intergroup activities in the significant level P≤0.05.The results showed that there is no significant difference between experimental group and control group in static and dynamic balance's triple tests. But in after test, experimental group had a better performance than control group. t exam results always showed the significant difference between experimental group's pretest and after test in every 3 balance test, while no significant difference were observed between the control group's pretest and posttest. Balance improvement which has been obtained from aerobic exercise program can be ascribed to impact of the mentioned activities in improvement of muscle endurance, range of joints motion, neural control of movements and psychological factors of students. Nevertheless, long term studies is required for studying effects persistence and long term consequences of this activities.
