Sport for development (SFD) initiatives have faced numerous criticisms around the focus on individual-level (micro) outcomes and lack of integration at the community (meso) and structural (macro) levels. As a result, there is growing recognition that programmes need to find ways to work with and engage a wide range of community members and stakeholders through more inclusive, participatory approaches. One such approach is known as Living Labs. In the following conceptual article, we present the Sport and Social Cohesion Lab (SSCL) project, which implemented a Living Lab approach in various sport-based programmes from four different European countries. The main components of the Living Lab framework are presented, and practical insights are derived from the project. In addition, the unique and sometimes critical role of sport is reflected upon in relation to the Living Lab context. Through this, this article provides practitioners and academics with potential building blocks to implement Living Labs and/or embed participatory approaches in sport and physical activity contexts and social settings more generally.
We investigated the effects of reflex-based self-defence training on police performance in simulated high-pressure arrest situations. Police officers received this training as well as a regular police arrest and self-defence skills training (control training) in a crossover design. Officers' performance was tested on several variables in six reality-based scenarios before and after each training intervention. Results showed improved performance after the reflex-based training, while there was no such effect of the regular police training. Improved performance could be attributed to better communication, situational awareness (scanning area, alertness), assertiveness, resolution, proportionality, control and converting primary responses into tactical movements. As officers trained complete violent situations (and not just physical skills), they learned to use their actions before physical contact for de-escalation but also for anticipation on possible attacks. Furthermore, they learned to respond against attacks with skills based on their primary reflexes. The results of this study seem to suggest that reflex-based self-defence training better prepares officers for performing in high-pressure arrest situations than the current form of police arrest and self-defence skills training. Practitioner Summary: Police officers' performance in high-pressure arrest situations improved after a reflex-based self-defence training, while there was no such effect of a regular police training. As officers learned to anticipate on possible attacks and to respond with skills based on their primary reflexes, they were better able to perform effectively.
Various discourses construct youth sport as a site for pleasure and participation, for positive development, for performance and for protection/safeguarding. Elite youth sport however continues to be a site for emotionally abusive coaching behaviour. Little attention has been paid to how the institutional context may enable or sustain this behaviour. Specifically, how do coaches and directors involved in high-performance women’s gymnastics position themselves in relationship to these discourses to legitimize the ways they organize and coach it? We drew on a Foucauldian framework to analyse the technologies and rationalities used by directors and coaches of elite women’s gymnastics clubs to legitimize and challenge current coaching behaviours. The results of the 10 semi-structured interviews showed how coaches and directors legitimized coaching behaviour using discourses of pleasure, protection, performance and of coaching expertise and assigning responsibility for current coaching behaviour to athletes, parents, (other) coaches and global and national policies.

Currently, many novel innovative materials and manufacturing methods are developed in order to help businesses for improving their performance, developing new products, and also implement more sustainability into their current processes. For this purpose, additive manufacturing (AM) technology has been very successful in the fabrication of complex shape products, that cannot be manufactured by conventional approaches, and also using novel high-performance materials with more sustainable aspects. The application of bioplastics and biopolymers is growing fast in the 3D printing industry. Since they are good alternatives to petrochemical products that have negative impacts on environments, therefore, many research studies have been exploring and developing new biopolymers and 3D printing techniques for the fabrication of fully biobased products. In particular, 3D printing of smart biopolymers has attracted much attention due to the specific functionalities of the fabricated products. They have a unique ability to recover their original shape from a significant plastic deformation when a particular stimulus, like temperature, is applied. Therefore, the application of smart biopolymers in the 3D printing process gives an additional dimension (time) to this technology, called four-dimensional (4D) printing, and it highlights the promise for further development of 4D printing in the design and fabrication of smart structures and products. This performance in combination with specific complex designs, such as sandwich structures, allows the production of for example impact-resistant, stress-absorber panels, lightweight products for sporting goods, automotive, or many other applications. In this study, an experimental approach will be applied to fabricate a suitable biopolymer with a shape memory behavior and also investigate the impact of design and operational parameters on the functionality of 4D printed sandwich structures, especially, stress absorption rate and shape recovery behavior.
