The non-athletes do not sit at the sidelines. They are not spectators, they are participants. By contrast, with Total-Mix sports, you find that coordination and practice, developmental skills and prefigurative intelligence rather than stature and stamina determine athletic proficiency. It is being suggested here that the professionals who develop activities and facilities, particularly ball fields, children playgrounds, and swim centers whether or not a modified spectrum of activities exists must take cognizance of the need for universal design which achieves Total-Mix as in the newly created ball playing sports, Bankshot Basketball and Bankshot Tennis. These sports were conceived as Total-Mix sports based on Universal Design.
Total mix suggests a court where one plays as much against oneself as against one another.
Or entirely non-competitively. It is possible for wheelchair athletes to play against each other on that court. It is possible for able-bodied people to play against each other on that court. But even able-bodied people can not all play tennis on the same level. A tennis player must find the very small sliver of the population with whom to play.
