Abstract
Purpose: The aim of the present study is to analyze the impact of rule modifications in competition on heart rate and heart rate variability in U-13 basketball players, considering maturity stage as a moderating variable.
Method: Forty basketball players with an average age of 12.91 (0.57) years participated in the study. The study was approved by the ethics committee of the University of Murcia (2828/2020). A quasi-experimental A-B study was designed, where A was a tournament with the FEB regulation and B a tournament with the modified regulation. The dependent variables analyzed were the time players spent in different heart rate zones and heart rate variability. Maturity stage was considered a moderating factor in the intervention effect.
Results: The results show significant differences in time in zone 4, reduced time in zone 5, maximum heart rate, and square root of the mean value of the sum of the squared differences. Maturity stage conditioned the intervention effect for square root of the mean value of the sum of the squared differences when players had a percentage of predicted adult height higher than 89.92%.
Conclusion: From a cardio protective perspective, it has been found that U-13 players spend more time in zones considered cardio protective during the modified tournament. In addition, the modification reduces the differences in terms of fatigue between early and late developing players.
期刊介绍:
Pediatric Exercise Science is a journal committed to enriching the scientific knowledge of exercise during childhood and adolescence. To this end it publishes information that contributes to an understanding of (a) the unique aspects of the physiologic, physical, biochemical, and psychologic responses of children to exercise, (b) the role of exercise in the treatment of pediatric chronic diseases, (c) the importance of physical activity in the prevention of illness and preservation of wellness, and (d) the means by which participation in sports may be made safer and more enjoyable for children and youth. Consideration will be given for publication of work by various methodologies consistent with the scientific approach.
Besides original research, the journal includes review articles, abstracts from other journals, book reviews, and editorial comments. Pediatric Exercise Science encourages the expression of conflicting opinions regarding children and exercise by providing a forum for alternative viewpoints. At the same time it serves as a means of accumulating a base of research information that will allow application of experimental data to clinical practice. The scientific disciplines contributing to this body of knowledge are diverse. Therefore it is the purpose of this journal to provide a common focus for disseminating advances in the science of exercise during childhood. In doing so, the journal allows the opportunity for cross-fertilization of ideas between disciplines that will potentiate the growth of knowledge in this field. Pediatric Exercise Science seeks to stimulate new ideas regarding exercise in children and to increase the awareness of scientists, health care providers, and physical educators of the importance of exercise during childhood.
