The goal of this Research Topic was to further our knowledge of exercise-related responses in organ recipients from rehabilitation to competitive sport. Indeed, the studies presented reflect our aim to consider organ recipients in the first 12 months post-transplantation (Vecchiato et al.) to those competing nationally and internationally (Hames et al.) and the support received at such events (Duncan et al.). Furthermore, the impact of high-intensity training was reviewed (Kayeye et al.) and the utility of web-based exercise and training resources (Da Silva et al.) and telehealth monitoring (Vecchiato et al.) was evaluated.
