Firstly, I don't think you understand what the word proof means. You have no proof. You have a story in which no testing was done, no variables were taken out of the equation, and to which the possible reason was assumed.
the cogency of evidence that compels acceptance by the mind of a truth or a fact
the process or an instance of establishing the validity of a statement especially by derivation from other statements in accordance with principles of reasoning
You have no facts or evidence, only an anecdotal story. Even if jogging were the cause, you still wouldn't have any actual proof that it was.
Also, I scoured Google, and your link was the only one that mentioned muscle loss from jogging. There was one site that mentioned muscle cannibalism, but that was from people on severe diets who had unhealthy weight loss.
Plus, if you're prepared to make claims, you have to be prepared to face criticism of those claims. That's how science/the world works.
