Like basketball, tennis and hockey, right.

We're not talking hobbyists. We're talking top level athletes. Men aren't just stronger. There are dozens if not hundreds of items they outperform women on.

The sports where women can actually compete with men are rare. For example marksmanship or long-distance marathon. Virtually every sport men have distinct and significant advantages.

Men have larger hearts, more lung volume per body mass, more red blood cells, more clotting factors which means they recover quicker and have a higher pain tolerance.

Testosterone allows for more rapid muscle gain as well as better recovery. So two people training the same exercises an identical amount of time, the man would have gained significantly more muscle mass and strength.

Men have higher blood pressure, which means they feel fatigue less than women. Men don't lose iron to menstruation, which means there's more iron for oxygen circulation in the blood.

These items basically make it so men are much better at almost all sports.

For example soccer. The US Women's national team lost to a team of high school age boys.

Men can kick harder, sprint faster, run longer, train longer & they gain more from training & they recover faster from training so they can do it more, they feel less pain so they can stay at max exertion longer, they can convert oxygen into energy faster so they can sustain all of this more than women,

Etc

There's a reason we have women's leagues. If we didn't have it, women wouldn't get to compete at a high level.

At a lower level, like hobbyist or local leagues the story may be different. There's more variance among the general population than amongst top athletes.

Serena Williams, #1 woman tennis player, can't hold a candle to the 203rd best man. Look up her interview about it. She's under no illusions about this

Co-ed. Had to look it up. "Male and female students being taught together in the same school". My mind is blown.
