The aim of this study was to assess responses to taper in elite athletes using computer simulations. Parameters of a non-linear model were derived from training and performance data over two seasons for eight elite swimmers. The fit between modelled and actual performances was statistically significant for each swimmer (r(2) = 0.56 +/- 0.06; P < 0.01). The simulations were used to estimate characteristics of step and progressive tapers that would maximize performance either (1) after regular training only or (2) after overload training of a 20% step increase in regular training for 28 days. The highest performance with a step taper was greater with than without prior overload training (101.4%, s = 1.6 vs. 101.1%, s = 1.4 of personal record; P < 0.01) but required a longer taper duration (22.4 days, s = 13.4 vs. 16.4 days, s = 10.3; P < 0.05). The optimal progressive taper led to a better performance only after the overload period (101.5%, s = 1.5; P < 0.001). Negative and positive influences of training were estimated as indicators of fatigue and adaptations to training respectively. During the optimal taper, the negative influence was completely removed, independently of the prior training, whereas the positive influence increased only after overload training. Our computer simulations show that the characteristics of an optimal training reduction in elite athletes depend on the training performed in the weeks prior to a taper. 相似文献

The history of the Journal of Sports Sciences is traced from the antecedents of its initiation to the current time. The developments of the sports sciences at large are reflected in the content of the journal. Its links with the international agenda are described, and related to landmark publications. Special attention is given to the relationships with international bodies, the International Society for Advancement of Kinanthropometry and the World Commission of Science and Sports. The expansion of sport and exercise sciences, both nationally and internationally, was reflected in the increased frequency of publication of the journal. Key areas in the kinanthropometric content are identified and placed in context. The review culminates in the highlighting of likely areas for future research. 相似文献
