The sub-discipline of motor learning frames understanding of skill performance and practice in sports, relevant for developing talent and enhancing expertise of athletes (Ribeiro et al., 2021). Research in this area has important implications for the professional support work of practitioners such as coaches, trainers and sport scientists (Woods et al., 2020). Ecological dynamics is a contemporary, transdisciplinary theory of motor learning, expertise and talent development in sport, which investigates dynamic person-environment interactions as the relevant scale of analysis for understanding human performance. Influenced and shaped by key ideas in biological, physical, social and anthropological sciences, an ecological perspective conceptualises athletes and sports teams as complex adaptive systems. An ecological perspective helps sport scientists to characterize the functional relationship that emerges from the continuous interactions of the individual athlete, task and environment, which is vital for understanding skill adaptation and talent development.
运动学习的子学科构建了对运动技能表现和实践的理解，与培养运动员的才能和提高运动员的专业知识有关(Ribeiro等人，2021)。这一领域的研究对教练员、训练员和运动科学家等从业人员的专业支持工作具有重要意义(Woods et al.， 2020)。生态动力学是一种当代的、跨学科的运动学习、专业知识和体育人才发展理论，它研究动态的人与环境的相互作用，作为理解人类表现的相关分析尺度。受生物、物理、社会和人类学关键思想的影响和塑造，生态学视角将运动员和运动队概念化为复杂的适应系统。生态学的观点有助于运动科学家描述运动员个体、任务和环境的持续相互作用所产生的功能关系，这对于理解技能适应和人才发展至关重要。

The aim of this study was to assess and compare by numerical simulations and analytical models the resistive forces, mechanical power and energy cost using two different types of road helmets (standard vs aero road helmet). An elite cyclist was scanned on the racing bicycle, wearing his competition gear and helmets. Numerical simulations by Computational Fluid Dynamics were carried-out at 11.11 m/s (40 km/h) and 20.83 m/s (75 km/) to extract the drag force. The mechanical power and energy cost were estimated by analytical procedures. The drag force were between 9.93 N and 66.96 N across the selected speeds and helmets. The power to overcome drag were 182.19 W and 1121.40 W. The total power lower and higher values were 271.05 W and 1558.02 W. The energy cost estimation was between 106.89 J/m and 381.40 J/m across the different speeds and helmets. The standard helmet imposed higher drag and demanded more power.
本研究的目的是通过数值模拟和分析模型来评估和比较两种不同类型的道路头盔(标准和航空道路头盔)的阻力、机械功率和能量成本。一名优秀的自行车手在比赛自行车上被扫描，他戴着比赛装备和头盔。在11.11 m/s (40 km/h)和20.83 m/s (75 km/h)的速度下进行了计算流体动力学数值模拟，以提取阻力。用分析方法估算了机械功率和能量成本。所选速度和头盔下的阻力在9.93 ~ 66.96 N之间。克服阻力的功率分别为182.19 W和1121.40 W。总功率高低分别为271.05 W和1558.02 W。在不同的速度和头盔下，能量成本估算值在106.89 ~ 381.40 J/m之间。标准头盔的阻力更大，需要更大的动力。

Small-sided games (SSGs) are a useful strategy to optimize the training process in soccer. The modification of some variables simultaneously implies several physical adaptations in soccer players. Thus, the aim of this study was to analyze the differences in the physical demands encountered by soccer players in different SSGs formats focusing on the scoring methods (i.e., mini-goals and regular goals with goalkeepers) and to the numerical superiority situations (i.e., no superiority, variable superiority, and fixed superiority). Eight elite young soccer players from the same team (age: 17.9 ± 1.1 years) randomly completed six SSG formats. Physical parameters (i.e., total distance [TD], distance covered at different speeds [D1, D2, D3, D4, D5 and D6], and distance covered accelerating [ACC] and decelerating [DEC]) were collected. The main results showed that the variable superiority (i.e., 4vs4+1) situation is more demanding, in terms of TD and distance covered at D3 and D4, in comparison to no superiority (i.e., 4vs4) and fixed superiority (i.e., 5vs4) situations both SSGs played with mini-goals and regular goals with goalkeepers. Besides, higher physical demands were registered in fixed superiority (i.e., 5vs4) than in no superiority (i.e., 4vs4) situation. Finally, only in a no superiority (i.e., 4vs4) situation higher distances at D1 and D5 were registered during the SSG played with mini-goals but higher distance at D3 was covered in the SSG format with regular goals and goalkeepers. Playing SSGs in variable superiority situation is more demanding in comparison to no superiority (i.e., 4vs4) and fixed superiority situations both during those SSGs played with mini-goals and/or regular goals and goalkeepers. In addition, SSGs played with mini-goals induced higher physical demands than playing with regular goals and goalkeepers during no superiority games. These findings could be useful for coaches in order to periodize the training drills within the microcycle to modulate the training session intensity.
