The 21st century is an era of convergence. The ideas of crossover and fusion have long in popular science and technology. Practical exercise learning draws inspiration from sport, medical science, nursing, literature, humanities, social welfare, and recreation. Exercise borrows ideas from many different sports games. You can no longer categorize exercise in terms of academic fields. Rehabilitations are interactive. Merging theory, method, technique, and function are now the core strategy in exercise rehabilitation. Human rehabilitation goes beyond medicine. Rehabilitation medical scientists are not merely doctor – they have to get involved in every step of the process, from planning to treatment to return to society. Exercise rehabilitation is embracing convergence. In university, bright minds are searching for convergence. With “convergence” as keywords, academic societies are establishing new agenda. This issue marks the first issue of year. Our motto from the start has been “crossover”. We set out to cover diverse fields of exercise, recreation, rehabilitation medicine, neuroscience, and humanities. We want to close up how academic fields cross into each other.
