A negative mean value for UV measures was observed（ 2.4 to 3.6 mm） without significant differences with increasing age-category（ p=0.09 to p=0.48）. Significant low correlations were observed between some UV parameters and stature, fat percentage, years of training, and left handgrip strength.Results： Ten gymnasts reported wrist pain with gradual onset and UV values were very similar between painless and painful wrists.Conclusion： The findings of this study do not directly support the thesis that gymnastics training and biological variables or wrist pain are associated with UV.展开更多
