Goalkeepers play a very specific and crucial role in water polo. They rely on advanced perceptual–cognitive (P–C) skills to make fast and accurate decisions. However, their daily training environment often lacks stimulation and representativeness of game demands. This was exacerbated by the COVID-19 pandemic, where noncontact practices became the “new normal.” In the Canadian Women’s National Team preparation for the 2020 Olympics, goalkeepers’ P–C training was made a priority. Led by the team’s mental performance consultant and experts from transdisciplinary fields, the initiative began with an evaluation of a broad range of P–C skills in goalkeepers. Leading up to the Olympics, a series of P–C activities (i.e., anticipatory training using video occlusion, eye–hand coordination, and visuomotor drills) were adopted based on ecological dynamics principles. Virtual reality technology and constraints-focused tools were used to enrich and diversify the goalkeepers’ daily trainings environment. This case study reports the evaluation of P–C skills, the context, and the way in which the P–C activities were implemented, as well as their holistic impact on goalkeepers. Reflections and limitations are also shared to encourage interdisciplinary efforts in sport psychology and increase awareness among mental performance consultants about the importance of psycho-perceptual-motor skill training for mental performance.
