There's a growing emphasis on multi-purpose fields to accommodate various sports, reducing the need for separate facilities. Technology integration is also prominent, with smart surfaces and LED lighting for better performance and fan experience. Inclusivity is another trend, with accessible seating and facilities for a wider range of athletes and spectators.
