Korea National Sport University (KNSU) has made a lot of contribution to the advancement of the physical education in Korea and elevated the nation's status in Winter Olympic Games recently. PURPOSE: The purpose of this study was to provide an overview of physical functions of athletes in four major sports. METHODS: A total of 45 elite athletes in KNSU were divided into four groups: golf (G, n=15), wrestling (W, n=15), boxing (B, n=15), and rowing (R, n=15). Body composition, basic physical fitness, and muscle strength were measured for each group. RESULTS: Regarding body composition, fat percent was the highest in the G group (B<R<W<G) (p<0.05), whereas the B group showed the lowest BMI (B<R<G<W) and muscle mass (B<G<W<R) with significance (p<0.001 and p<0.05) in relation to the top level groups. For the basic physical fitness, the G group showed significantly low scores in the sit-up (G<B<R<W) and long jump (G<W<B<R) as compared with the top level groups (p<0.05). Meanwhile, a significantly low record of the fastest 50m-run (W<R<G<B) was detected in the wrestling group in comparison to the B group (p<0.05). Also, the light flexion measured by the Isokinetic leg strength test (60°/sec) was found to be the highest in the W group, whereas it was the lowest in the G group (G<B<R<W, p<0.05). CONCLUSIONS: The results of the study are reflecting the varying characteristics of the four types of sports. Hence, this study may be used as a fundamental tool to predict physical functions of athletes, thereby allowing for improvement in their sports performance.
