Ah, but a common theme in definitions of "sport" is that it is for entertainment purposes. Competition for entertainment purposes. If there is a drumming competition, and drumming is a physical activity, and it provides entertainment, then wouldn't it qualify as a "sport"?
Tis obvious to all (almost all) that there is a very nebulous line between "sport" & "non-sport".
If any activity which has competition, entertainment, & a physical activity is a "sport", then I find this overly broad because it would include.....
- Tractor pulls
- Dog shows
- Board games like go....& even chess.
With those things, the human's physical activity is a tertiary component.
On the flipside, swimming is considered an Olympic sport, it is competitive in schools as well. Am I still considered to be participating in a sport if I jumped in a lake and doggie paddle for a bit? If I'm just leisurely swimming in a pool because, hey, it's a hot day and it feels nice, am I participating in a sport or a recreational activity? No one is keeping score, no one is competing against me, so is it a sport?
The level of activity is a factor.
Some swimming is definitely a sport.
Other swimming is just cooling off on a hot day. You young whippersnappers call this "chill'n", eh?
If you are snowboarding to compete for scores against others then isn't that different then doing it for yourself for fun?
It's a sport either way.
Competition isn't a required element.
If you have a basketball hoop on your garage and you grab up the ball and toss it through the hoop on your way to take out the trash, did you just participate in a sport? Or were you merely having a bit of fun in passing?
I say the latter.
A hard & fast rule in applying an imprecise word to a myriad of activities is bound to fail.
Such is true for others too, eg, pornography, art, game.
Tis more useful to grok the intent behind the word.
By the definition you proffer (Old Scratch's advocate, I presume), if you asked my what sports I've done/do, I'd have to say....
"The only sport I play is go."
"But I do have some hobbies, eg, weightlifting, hiking, snowboarding, bicycling."
