摘要
Introduction. - Our goal is to study the effects of tennis practice in pre-pubescent boys on bone remodeling, by means of enzyme activity involved in balance of matrix remodeling (MMP2 and MMP9). Results. - Mineral bone density has been found higher in the dominant arm (P < 0.0001) as well as MMP2 and MMP9 levels in plasma (P < 0.05). Conclusion. - Tennis practice in children increases bone remodeling, which can be assessed by MMP dosage, in addition of densitometry technique. (c) 2007 Elsevier Masson SAS. All rights reserved.
