Abstract Being successful sports science students, it is necessary to have good physical development throughout the 4 years undergraduate study program. Therefore, the aim of this study to investigate physical performance of the first year sports science students at Buriram Rajabhat University (BRU), as a basic knowledge for planning and develop exercise program. The seventy-eight sports science students, aged between 17-18 years old, were recruited in this study both male (n=50) and female (n=28). The results of baseline clinical characteristics were determined by body mass index (BMI) and percentage of total body fat. BMI was shown in normal range 73.08 % (18.5-22.9 kg/m2), less than normal as underweight 16.67% (<18.5kg/m2) and obese 10.25% (≥30 kg/m2). Percentage of total body fat was shown normal 41.01% and high to highest range 42.31%. While this result of less than normal was showed 16.67%. Assessment of physical performance were investigated sit and reach test, hand grip test, the sixty second chair stand test, Zig-Zag run test and distance run (1600 m.) test. The results of sit and reach test for trunk flexibility was shown mostly in normal range 47.44% and high to highest 34.61%, while less than normal 17.95%. Hand grip test for hand and arm strength was showed mostly in low (34.62%) to lowest range (14.10%), while in normal range was shown 30.76% and high 14.11% to highest 6.41%. For the test of leg muscle strength and muscle endurance by using 60 seconds chair stand, was showed mostly in high, to very high range 93.59%. Zig-Zag run test for power, speed, quickness, and body control and the results of this test showed 100% of very high range. Distance Run (1600 m) test was done to indicate muscle and cardio-pulmonary capacity. It was showed in high range 38.76% and normal range 34.61%, while the less than normal was shown 20.52% and highest 3.85%. For the conclusion of this study, we found that the first year of BRU had the problem in BMI 30% both obese and underweight. Additionally, they had arm and hand strength, muscle and cardio-pulmonary capacity, trunk and flexibility less than normal 49%, 21% and 18%, respectively.
