Sometimes when things don't make sense, it doesn't necessarily mean it won't work. Instead of applying physiological theory mate, go for a run. Try learning the words of the Marty Robbins classic, "El Paso". See if you can kiss Felina good bye.
It Slows down your breathing and heart rate when under extreme stress and if you practise it will become natural. ps didn,t need it against West as I won every round:smoke
"It's raining men"???? And you better get them wankin spanners in tune sunshine because if Yasi comes visitin', it'll sing real loud Take care up there:good
...we didn't fare too badly Pop's....tree's down all over the joint but no real damage....we lost power for a few days...thank **** that Yasi slowed just enough so by the time she hit the tide was goin' out...we were lookin' down the barrel of a 4 meter tidal surge....that woulda took us out for sure.:thumbsup
Might be the same reason, or at least one of the reasons, why the Yanky soldiers all sing when they run together in formation.
Funny, I kind of came across this method by accident, although I actually whistle instead of sing...it's a good way to regulate your breathing if you've been away from your roadwork for a while and it's your first couple of runs back into it. I also always visualise breathing with my stomach instead of with my chest i.e. deep diaphragm breathing as opposed to shallow upper chest breathing.
