For those reading:
"Slipping wheels" means that during a high-torque event like a standing start or jump from a slow roll, the rider yanks the chain so hard that the rear wheel slides forward in the dropout. The right side only. This jams the wheel to the left and it rubs the chainstay and causes the wheel to stop as though brakes were applied.
This is also why, when using chain tensioners, you really only need on on the right side.
There are two types of tensioners: Pull and Push.
1) PULL: The "lollipop" or BMX style. This hooks on the axle and is affixed to the dropout from the outside. You tighten it and it pulls the axle backwards and doesn't allow it to slide forwards when the chain pulls.
2) PUSH: Internal/Integrated style. This is a screw that is built into the dropout and you screw it (away from the front of the bike) and it pushes the wheel axle away from the frame. It essentially shortens the dropout and won't allow the wheel to come forward when set. This is the modern style. You'll see this on mid and high-end bikes.
"Why does it slip?"
Sometimes, you have a combination of steel wheel nuts and steel (or steel plated) dropouts, the metals are both so hard, that they actually slip against each other if given enough force. Higher-end bike manufacturers (LOOK 496, Felt TK1, Tiemeyer) mitigate this by using titanium (or titanium plated) dropouts. Titanium is strong, but softer than steel, so the steel wheel nut "bites" into the dropout and holds tighter.
So, when you read about Ti Dropouts, it's not a "bling" thing. It's a functional thing.

Further...
Torque is a function of strength and weight of the rider. Simply put, strong guys make a lot of torque. Heavy guys make a lot of torque. Heavy guys that are strong make a helluva lot of torque.
I've always been a heavy guy. I was a 195 lb HS athlete...and got heavier after I graduated. When I rode single-speed and fixed gear street bikes, I'd have to use tensioners simply because I'd pull wheels when driving hard up hills and whatnot. So, that abnormally high torque was more a function of my weight than my power.

Yeah, and I've never been over 180 lbs and usually race between 170-175, but still for me it's better safe than sorry with the tensioners. I've seen a lot of awkward looking crashes (that hurt) from slipped wheels at standing starts. Sometimes the really low speed crashes can hurt worse than high speed, where of you're lucky you will slide.

i slipped a wheel not knowing it happened. i was thinking why does my gear feel so big #pause and it happened to be too tight of a chain.
standard track bolts...
so i bought these...
the tensioners on my current frame are seized. i should probably blast that area with wd-40 so i can use them just in case. i rarely change gearing even for warm up...
i miss having a disc because it made that cool whoosh whoosh sound lol.

yeah, these suck for holding wheels.
And these help somewhat.
Woosh sound OP.
You are just hurting yourself. You are working too hard and wasting energy you could use for racing. As the saying goes, "Train how you race and race how you train." You should get into the habit of warming up and switching wheels and whatnot. That way when you have to do it in a big event, it won't be frustrating.
To extend that: Weeks leading up to big events like Nationals, it's advisable to do your workouts as though you would get no track time at the event. So, warm up 100% on rollers then race your race day or do your workout. I asked an Olympic racer if it's even possible to do a kilo with only rollers as a warmup. No standing starts, no rolling jumps. Just rollers. His response was, "Yes. You learn to do it and your performance won't be diminished."

In Japan the club guys hardly ever changed gears for warm up. I was stupefied at first, but that's just how they do it.

Regarding warming up and staying warm. Remember the British Team had special pants that had heaters in them for the London Olympics. Not sure if it was to warm the athletes up or keep them warm between warmup and the event.
I read in one study that the objective to obtain optimal athletic performance is to literally raise the temperature of the muscles.

i mean, a good rule of thumb is the shorter the race, the longer the warmup. that goes double for track racing; in a crit, you might be able to say "i'm just gonna tailgun for the first fifteen or twenty minutes and get loose," but that's pretty impossible even in a 'long' track race.

Never in my life would I have thought I would need a kerosene heater for a track race up until those races. Hopefully we have enough common sense to move them a few weeks later this season.

Brean also mentioned the possibility of having Fall series of races in addition. I'm really hoping that will happen.
