I started watching UFC and a silly question occurred to me - what can be considered a sport, and is there a way to objectively classify something as a sport?
In my view, sport consists of two parts: (1) pursuing a goal that is treated as important as the outcome of an activity, and (2) the skills and physical abilities required to achieve it most effectively within certain boundaries and/or restrictions.
On this view, a sport can be described as a combination of a defined goal and constraints that matter to a group of people. If the goal of a sport can vary arbitrarily depending on what a community values, then the goal seems like a poor basis for an objective measure of "sportness". That leaves the constraints (rules, limits, permitted means) as a more measurable candidate for quantifying sport.
If we focus on constraints, we might try to list physically possible constraints relevant to human beings and rank them by their significance for embodied existence. On that scale, I doubt there is any constraint more significant than the stable functioning of the human body itself.
Returning to goals, even if we can’t measure "sportness" by the goal directly, we can note that goals can be pursued more actively or more passively — through action or endurance. Given the importance of the body and this action/endurance distinction, it seems to me that martial arts might count as "maximally sporty", because they require both active skill (inflicting damage using one’s body (and knowledge)) and endurance under the sport’s constraints (withstanding damage inflicted by the opponent directly to your body).
Am I right to reduce "sportness" mainly to the structure and severity of constraints? Or is there a better way to think about what makes something a sport?
