Does wearing the long hair pieces slow you down?

Swag and keeping it real is more important than knocking a tenth of a second off of your time

yes, that would help. Not wearing jewelry would help too.

I am sure they have measured if it makes a difference and I would venture a guess that it doesn't. If it cost a .10 they wouldn't do it. There is too much money on the line to do something that slows you down.

Wouldn't the women track stars run faster without the hair pieces?

This is what I wrote in an earlier thread:

Her hair produces a "boat tail" which reduces the strength of the longitudinal vortex reducing her coefficient of drag.

Her fake nails have the proper radius to become "air paddles" increasing her forward force.

Sometimes referred to as Black Girl Magic in track circles it is a subtle but effective form of cheating.

This form of cheating and the results can easily be seen in the careers and results of Flo Jo and JJK.

In seriousness, it is actually possible the hair actually spoils the longitudinal vortex and does provide some minuscule aero advantage but that would need some significant CFD modeling and verification in the wind tunnel.

The negative hair, nails and jewelry (actually being worn) won't produce a difference that is above the least count of timing and likely less than a frame of the camera used for the photo finish examination. It however can be a positive mentally for someone that is used to wearing them and the feel it gives them running.

I am definitely not a great golfer but I have worn a watch my entire life while playing golf. I feel odd and just off without one. When I started wearing mechanical watches which at least arguably don't like being subjected to the shocks encountered in golf I leave a quartz watch in my golf bag and switch them out when I play. The accoutrements some runners wear could be a negative on the clock but it would be measured in fractions of a millisecond, the positive in an elite athlete's head of being comfortable is potentially worth far more than that.

Yeah, the track & field women really underperformed in Paris.
