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
