Exposure Compensation is not the problem.
You have bracketing turned on, with one stop increments. Turn that off and that particular problem is solved.

Right On

If the shutter speed kept changing and you were not changing it, then you were NOT in manual mode. You had to be in program or aperture priority. Looking at the shadows in your photos, it appears the light conditions were changing as you shot, and the camera was compensating by varying the shutter speed so your pictures would be well exposed. To control shutter speed in action shots, set your mode to shutter priority with an ISO sufficient to keep the aperture range for a reasonable depth of focus - around 8 for that subject matter.

Unless auto bracketing is enabled, as that will vary shutter speed while in Manual mode.

He was wrong! He suggested Exposure Compensation was the problem, which is not at all logical.

Did you use exposure compensation during your shooting session? On a Canon camera, if you use EC in manual mode, the shutter speed will change to "compensate" for your selection. If you shoot at what you set on the camera, the SS will not change in manual.

The camera will not change the shutter speed in manual mode based on an EC setting. It changes the metering so that it displays correct exposure as a function of the EC.

Absolutely spot on.

Dead wrong. Read the thread. In Manual mode the shutter speed will be automatically changed, just as the OP described and demonstrated, if Auto Bracketing is turned on. In this case it was.

You are right -- I picked the wrong quote. I wanted YOURS… YOU are a great teacher!! Sorry about that!

Amazing. Everything that typically happens on UHH, happened in this post: incorrect answers and repeated correct answers without reading through the string.

Thank you for the overly kind words.

All I can tell you is that when I change my EC to increase or decrease the exposure, the SS changes appropriately. This is obviously not bracketing which is under and over exposing for the reasons we all know. Does Canon EC work differently than other cameras?

According to my 70D and T3i manuals, EC is adjustable only in P/TV/AV. In manual mode, you can only adjust AEB.

Sorry if I missed it but just to round out the explanation of exposure compensation (ec)...
Your camera's light meter is designed to average out all the luminance values it detects to a mid-tone (16% grey). The metering mode you have set on your camera will also affect this. Center weighted metering averages everything but pays more attention to the area in the center of your viewfinder versus evaluative metering which breaks the whole scene down into segments and uses the cameras computer to try and figure out what parts are most important when averaging the light. In scenes with an even distribution of light and dark areas this works very well but in scenes that are mostly dark or mostly light the meter can be fooled. A common example of this is a scene with a bright sky and snow on the ground. Because everything is so much brighter than a medium grey and the meter wants to expose to make it medium grey it gives you an exposure setting that is not allowing enough light to your sensor (or film); ie underexposure occurs. Knowing this happens in this type of scene you can can use the exposure compensation function to tell your meter to read the scene differently.

You are right. Never considered autobracketing because it is a feature I never use - in fact think it is a useless function- even a meddlesome function as this OP's post indicates.
