Cool-down useless at best?

Correct me if I’m wrong but I think Charlie has mentioned somewhere that muscles after training take 4 hours to restore to their normal length. By stretching them straight after you can get them back to normal length straight away thus improving recovery by 4 hours.

Certainly seems that way with me and my clients too. Perhaps even longer time period (recovery period) with older (nearing 30) clients.
