You get rewarded by qualifying. If you perform better in the heat that doesn't mean you should get an advantage in the race. Random allocation would be better.

You already get rewarded for better performance in the heat by being allowed to participate in the race!

Yes...that's what I'm saying.

All protein derived from veggies are considered incomplete when compared to animal derived protein, which also require substantially more volume to obtain the same nutritional content. You only need to look at the amount of waste (feces) between a veggie based diet and an animal based diet - the difference is staggeringly different. I.e. far less waste is produced, because far less is required when eating animal base…

Dunno man, I poop a lot more (and stinkier) when I eat more meat as compared to vegetarian dishes. Considered incomplete by whom? References?

> Considered incomplete by whom?

Probably means incomplete in that most plant based protein sources do not contain all essential amino acids.

I was a college swimmer, qualified for Olympic Trials in 2012 and 2016. There are absolutely slow and fast pools. It basically comes down to two things: 1. The depth - which is only 7ft in Paris, unusually shallow for a competition pool. 2. The sides. Does the water spill over the sides into the gutters, or smash into a wall and bounce back, creating more chop. A trained eye can see all the swimmers in Paris struggli…

This is yet another reason on the huge list of reasons to keep the Olympics in Athens and just use the same facilities each time.

If it's too shallow the swimmers arms hit the bottom ... Slightly deeper and there's drag from the floor as their arms barely miss it. That effect persists until it doesn't .. now it's deep enough. It needs to be deep enough that vortex's created by swimmers have disapated by the time they reach bottom and reflect back to the surface so as to not interfere with following swimmers or swimmers returning.

> If it's too shallow the swimmers arms hit the bottom Is it’s deep enough, the gravitational mass of the water will form a black hole and squash the swimmer to death.

Well before that the hydrogen atoms would fuse into helium and release vast amounts of energy, killing all the swimmers, spectators, and many people in Paris.

I wonder if there is some kind of mesh that you could put on the bottom of the pool to absorb the interior waves. Sort of like soundproofing in a recording studio.

A lining of triangular foam blocks would make for an interesting pool. It might work, but practicality (installation, cleaning etc.) would likely rule it out

Years ago Johannesburg put in an Olympic bid. Because of the high altitude (1753m) they had issues affecting a number of disciplines when it came to records due to the thinner air...

If I recall correctly: - Javeline would go further (less air resistance) - High cardio events would go slower (less oxygen for athletes)

That would have been a "slow pool" factor all things being equal!

As we're probably familiar, dealing with an under spec computer for doing your job is frustrating. Even marginal differences in speed can be perceivable and lead to a growing dissatisfaction over time. I imagine these competitors face the same sort of frustration when dealing with a 'slow' swimming pool like this.

I'm no expert, buy there also seems to be loads more stuff lying on the bottom of the shallow floor than I remember from previous Olympics. Not even sure exactly what it is - large white panels and other equipment that the swimmers don't look that far off touching when underwater (not the robot cameras which are relatively unobtrusive).

Wouldn’t the underwater camera on a track cause currents?

As much as it's about winning the medals, this is about setting personal and world records, too.

Regardless, they have to make do with what they have. Nobody is moaning that the weather affects triathlon timings.

If the organizers controlled the weather and made it rain, people would absolutely be complaining.

Yes, those on the outside will have choppier waters as the water bounces off the sides of the pools. The modern competition pools do a pretty good job of reducing this effect, but it is always there.

Could probably increase fairness by doubling the width and throwing away the last few lanes (leaving them empty). But would that incentivize the edges? I don't know.

They could get almost perfect fairness in any kind of Olypmic-style race by just letting competitors all use exactly the same lane, one after another.

In earlier times, measuring equipment wasn't accurate enough, so races had to be done in parallel with people starting at the same time. Today, that's no longer necessary. In fact, people racing one after another is exactly how we hand out world records.

Of course, the Olympics and other events like them aren't there to find the best athletes in some absolute sense; these events are there to entertain spectators. Otherwise, swimmers could just do time trials at home and mail in times.

And spectators like people racing each other at the same time.
