The relationship between physical and technical performance characteristics of young soccer and basketball players: A comparison between two sports

BACKGROUND: The purpose of this study was to examine the relationship between physical and technical performance characteristics of young athletes in soccer and basketball, as well as to see the differences in between sports. METHODS: Fifty-seven male players (soccer: N.=30, age 13.53±0.51 years; basketball: N.=27, age 13.56±0.51 years) participated in this study. Anthropometrical (height, weight, BMI, body fat), performance (VO2max, HRmax, perceived exertion, lactate concentration, 10-m and 20-m sprint, agility, vertical jump) and technical (passing, dribbling, shooting) tests were carried out. RESULTS: Anthropometrical, performance and technical tests showed a significant effect of sport type on height, weight, BMI, VO2max, HRmax, perceived exertion, 10m sprint, 20m sprint, vertical jump (P≤0.05), but a non-significant effect on agility (P=0.15) between soccer and basketball players. Soccer players showed significant moderate to strong correlation among the majority of performance and technical characteristics (P≤0.05) but not in basketball players, with the exception of the weak correlation observed between lay-up and VO2max, the weak to moderate correlation between lay-up, vertical jump and 10m sprint and the weak to moderate correlation between 20-m left hand dribbling, 10-m sprint and vertical jump respectively (P≤0.05). CONCLUSIONS: Basketball players indicated different level of anthropometric characteristics than soccer players who predominated in performance characteristics and showed a stronger relationship between performance and technical variables. Basketball players were taller and heavier than soccer players, while soccer players predominate in performance characteristics. Furthermore, a moderate to stronger relationship was found between performance and technical variables for soccer subjects but not in that scale for the basketball counterparts. © 2021 Edizioni Minerva Medica.

Overview of Transactional Patterns : Combining Workflow Flexibility and Transactional Reliability for Composite Web Services

Abstract. In this paper, we present an approach to easily define flexible and reliable services compositions. We introduce a new concept called transactional patterns to specify flexible and reliable composite Web services. A transactional pattern is a convergence concept between workflow patterns and advanced transactional models. It can be seen as a coordination pattern and as a structured transaction. Thus, it combines workflow flexibility and transactional processing reliability. Designers can simply connect together a set of transactional patterns to define a composite Web service. We use a set of techniques to ensure control and transactional coherence between patterns inside a services composition
