In collective sports, the match analysis is fundamental in order to improve the quality of coaches' intervention. Nevertheless, the generality of the systems are based on notational analysis which does not allow a deep understanding about the collective behaviour of the team. Therefore, the main goal of this study is to update and design new tactical metrics that allows an improved online knowledge about the teams' behaviour. Tactical metrics such as the teams' centroid, teams' stretch index and teams' effective play area will be presented throughout this study, validated by means of a single match experimental case study. Results suggest the potential of the herein proposed tactical metrics, providing relevant and online information to the coaches over time, thus allowing new opportunities to improve the quality of their intervention.

Drawing from the effort‐recovery model, the authors analyzed the role of daily sleep quality as a driver for self‐regulatory resources and consequently of task and contextual performance. Specifically, the authors hypothesized that self‐regulatory resources would be a potential mechanism for enhancing workers' performance after a good night's sleep. Moreover, relying on the COR theory, the authors proposed health‐related indicators (mental health and vitality) as intensifiers of the previously proposed indirect effect. Daily diary data were collected from 97 managers over five consecutive working days (485 daily observations) and analyzed using multilevel analyses. Sleep quality was positively associated with managers' self‐regulatory resources and (task and contextual) performance at the person and day levels. Additionally, results provided support for most of the assumed indirect effects of sleep quality on both performance dimensions via self‐regulatory resources. At last, the findings evidenced that these indirect effects were moderated by health indicators in a way that lower scores on health intensified such positive effects. Organizations should create mechanisms that could promote their workers' awareness of the potential benefits of sleeping well at night as well as its impacts on both self‐regulatory resources and performance. The current intensification of workload together with working after hours may pose a risk to this important resource source for managers. These findings emphasize the day‐to‐day variation in self‐regulatory resources needed to perform and that workers' sleep quality has the potential to stimulate a resource‐building process for such benefits.
