THE CORE STRENGTH, ENDURANCE AND FLEXIBILITY IN CHILDREN WITH WINDSURFING: A PILOT STUDY
 
The goal of this cross-sectional study was to compare core strength, endurance, and flexibility of childeren with windsurfing to those of healthy adolescents. Nine children in windsurfing and 9 healthy-children were included with a mean age of 14.332.69 years and 11.331.22 years, and mean body mass index of 19.692.23 kg/m2 and 19.663.28 kg/m2, respectively. Trunk flexion and extension muscle strength were evaluated by using hand held dynamometer and core muscle strength was evaluated with stabilizer. Biering-Sorenson test was performed for static muscular endurance of trunk flexion and extension, and dynamic muscular endurance of trunk flexion and extension were evaluated with sits-up test and modified push-up test, respectively. The sit-and-reach test and fingertip-to-floor test assessed flexibility. All statistical analyses were performed with the Statistical Package for the Social Sciences20.0. The level of significance considered was 0.05 for Mann Whitney-U test. The children in windsurfing (26.3524.20) had significantly higher holding time in Biering-Sorenson test for trunk flexion(6.52.5) and higher muscle strength all trunk muscle (6.462.79 for trunk extension, 6.502.50 for trunk flexion and 7.449.22 for core muscle) than healthy-controls(p=0.006, p=0.02,p=0.02 and p=0.01,respectively). Besides, repetition counts of modified push-up test was significantly higher in the children in windsurfing (20.006.92)than healthy-controls (5.898.31) (p=0.003). Sit-and-reach test distance and fingertip-to-floor test distance in flexion were significantly higher in the children in windsurfing (p=0.03 and p=0.006,respectively). In conclusion, children in windsurfing have higher muscle strength, static endurance of trunk flexion,and dynamic muscular endurance of trunk extension and muscular flexibility compared to their healthy peers.
