Morphological proportionality in elite age group North American divers.     

D Sovak  M R Hawes  K Plant 《Journal of sports sciences》1992,10(5):451-465

The purpose of this investigation was to describe the morphological parameters that characterize elite age group divers. Comparisons are made to normative age group data from the Coquitlam Growth Study and the constancy of important characteristics from age group to age group is examined. Data were collected on 27 male and 28 female elite divers who participated in the 1990 North American Age Group Diving Championships. Body build, body composition and skinfold corrected diameters were determined from 36 anthropometric parameters and analysed by ANOVA, t-test and Phantom z-scores procedures. All age groups except the 14- to 15-year-old males were significantly (P < or = 0.05) shorter than their norms but recorded higher androgyny index values. The estimated relative muscle mass increased significantly (P < or = 0.05) with age for males at all ages (40.8-46.3%). The 16- to 18-year-old females had a significantly (P < or = 0.05) larger relative muscle component compared to the younger age groups (40.1-38.4%). When normalized for height, active tissue development of the extremities was comparable between the sexes except in the forearm. The results indicate that at all age levels short stature is an important characteristic for divers. Analysis of regional active tissue development provides further insight into sport-specific prerequisites for success at elite levels.  相似文献

对我国运动员进行心理表象训练新程序的理论探讨   总被引：2，自引：0，他引：2  

高守清 《四川体育科学》2002,(4):9-10,15

表象训练是体育运动实践中运用最广泛的训练方法之一。我国在此领域远远落后于日本，其主要因素包括表象训练的方法、个体差异和情境因素：日本新近开发的心理表象训练程序(简称MITP)，几经实践运用，不仅训练效果良好而且在运动训练和比赛心理的理论方面产生了积极的影响，检验了有关表象训练的理论问题，认为动觉表象、视觉表象和想象表象有机结合是提高心理训练效果的良好途径；对MITP作一些理论探讨，目的在于为我国体育运动心理学理论建设提供一点参考。  相似文献
