As theories of sports rehabilitation continue to evolve, functional residential design has been proposed as a new way to help athletes recover from injury. Athletes require not only appropriate medical interventions but also support in their living environment during their recovery from injury. By integrating wellness, healing, and adaptive spaces, functionalized residential design for sports rehabilitation can provide multi-dimensional assistance both physically and psychologically, thus facilitating the overall recovery of athletes. This paper analyzes the impact of functionalized housing design for sports rehabilitation on the post-injury recovery effects of professional athletes. The research subjects were 30 professional athletes in a province, which were divided into experimental and control groups by using experimental method and questionnaire survey method. The experimental group performed sports rehabilitation training in a functionalized residential environment, while the control group trained in a traditional training room. The recovery effects of the two groups were analyzed by measuring the indexes of blood lactate, creatine kinase, sports performance and psychological condition. The results showed that the experimental group recovered blood lactate more rapidly than the control group, with p-values of 0.013 and 0.008, respectively, and the experimental group recovered creatine kinase significantly better than the control group, with p-values of 0.004 and 0.001, respectively, and the experimental group showed a more significant improvement in athletic performance and psychological condition, with an increase in explosive power of 1.01, compared with 0.49 in the control group, with p-values of 0.002. The conclusion shows that the design of functionalized housing for sports rehabilitation can effectively promote the post-injury recovery of professional athletes, enhance sports performance and improve psychological status.
