“…Speed might be limited by the minimum time necessary to generate the propelling impulse (Weyand, Sandell, Prime & Bundle, 2010) and by the degree of stiffness of the lower limbs. Millett, Moresi, Watsford, Taylor & Greene, (2018) showed that stiffer athletes showed lower contact times in sprint test than the control group (p<.001 -.003). In a combat sport, Zaggelidis et al (2012) reported that higher level athletes present lower contact time compared to lower level athletes when executing different vertical jumping tasks (p<.05 -p<.01).…”

Abstract. Background: Fencing is an Olympic combat sport divided into three different disciplines: the foil, the épée and the sabre. The most used attack movement by fencing athletes is the lunge. Problem and Aim: The main objective of this study was to correlate joint positions of the lower limb with the contact time of the lunge attack followed by the recoil. Methods: Ten male (mean ± SD, age = 22.0 ± 5.7 years; body mass = 70.3 ± 11.1 kg; height = 174.6 ± 9.4 cm) fencing athletes (sabre) from national and international teams participated. Results: We observed a correlation between the contact time of the lunge attack and hip angle (r = -.75, p = <.05). Conclusions: The degree of flexing of the hip joint, evaluated through video, was inversely related to the contact time in the lunge attack and recoil in male sabre athletes.Resumen. Antecedentes: La esgrima es un deporte de combate olímpico dividido en tres diferentes armas: florete, espada y sable. El movimiento de ataque más utilizado por los esgrimistas es el fondo. Problema y objetivo: El principal objetivo de este estudio fue correlacionar las posiciones articulares de las piernas con el tiempo de contacto del fondo seguido por el recobro. Métodos: Diez esgrimistas (sable) masculinos (media ± DS, edad = 22.0 ± 5.7 años; peso corporal = 70.3 ± 11.1 kg; talla = 174.6 ± 9.4 cm) de equipos nacionales e internacionales participaron. Resultados: Observamos una correlación entre el tiempo de contacto del ataque de fondo y el ángulo de la articulación de la cadera (r = -.75, p = <.05). Conclusiones: El grado de flexión de la articulación de la cadera evaluado a través de video, estuvo inversamente correlacionado con el tiempo de contacto en el ataque de fondo y el recobro en sablistas masculinos.

“…Research in the sport sciences has developed new analytic capabilities based on AI algorithms that analyse large datasets in sports such as professional football (e.g., Herberger & Litke, 2021) and swimming (e.g., Costa et al, 2021). Technologies used in elite athlete coaching included force‐time curve analysis of athletic movements such as countermovement jumps, isometric joint position holds and sidestep changes of direction (Millett et al, 2018), and GPS tracking of athletes in training and competition to profile running intensities, accelerations and decelerations. Although numerous algorithms to support sense making from this data have been developed (e.g., De Silva et al, 2018), few of them support explicit creative thinking.…”

Designing new digital tools to augment human creative thinking at work: An application in elite sports coaching

Creative thinking is desirable in many professions. This article reports new research that followed a design science approach to develop and investigate a co-creative tool called Sport Sparks in one professionthe coaching of professional football players.In response to a coach entering a text description of a coaching challenge (e.g., struggling to maintain the fitness of an athlete) into the tool, the tool automatically generated potentially novel ideas (e.g., reducing game time and changing their nutrition) that the coach could select and/or adapt and evolve into a simple action plan (e.g., which links nutrition to increased game time). This Sport Sparks tool was designed to be an example of human-centred artificial intelligence that aspires to empower humans, to deliver high levels of human control as well as automation, and empower people rather than emulate their expertise. It was engineered with rulebased reasoning to automate the generation of potential new ideas that coaches could select and refine during interactions which provide high user control over this automation. The potential of such a co-creative tool, and value of the guidelines, were demonstrated during the tool's evaluation by coaching practitioners at a Premier League football club. The practitioners used the tool to generate new ideas to coaching challenges, and reported evidence of different forms of creative thinking, although some also reported the need for more support for creative collaborations and solution planning. The paper ends by discussing future directions for both the Sport Sparks tool and other co-creative AI tools.co-creative AI tools, creativity, design guidelines, elite coaching, human-centred AI, sports | INTRODUCTIONCreativity is defined as the ability to produce work that is novel and original, as well as appropriate and useful (Sternberg, 1999). The need for more creative thinking and outcomes is well-documented, for example, to solve complex problems (e.g., Isaksen et al., 2011) and facilitate innovation (e.g., Design Council, 2011). Digital tools to support human creativity and more creative engagement has become one of the means to meet this need (e.g., Candy, 2007). People use these tools to, for example, discover new information, synthesize novel content from existing material,
