Abstract

AIM:

The relationship between extreme exercise and coronary artery disease is not well understood, and the information available is contradictory. The aim of the present study was to determine whether strenuous endurance exercise, performed under conditions in which the partial pressure of environmental oxygen varies constantly, can induce myocardial cell injury.
METHODS:

Plasma urea, creatinine, creatine kinase, myoglobin and cardiac troponin I (cTnI) concentrations were measured the day before and immediately after a mountain bike challenge (distance 95 km, cumulative altitude difference 2340 m) in eleven amateur male cyclists.
RESULTS:

All biochemical markers of muscle cell damage increased significantly after exercise. Although cTnI concentrations also increased significantly, they remained below the threshold (0.5 microg/L) indicative of acute myocardial infarction.
CONCLUSIONS:

In male, amateur mountain bikers, this kind of strenuous exercise may induce sub-clinical myocardial injury.
I have a failsafe method to stop the old ticker exploding Rich, just stop at 94km's.
Now I know whats wrong with my body after a spin .......... heart attack
thanks Don.......
its ****in awesome..I was in the Pyrenees in the 80's, nearly starved to death, nearly OD'ed twice and forget it..i'll write the remainder of the story into my Biography..if I had the money I'd do it..I'm fed up running spins worrying about the NPS and sick of encouraging other people to ride their bikes.
At what stage does it just become masochism? I know it would be very satisfying to finish but **** me where's the Craic in that!

Nail on the head there Lynchy, I dont think I could face a challenge like that again and this one is twice as long!!!!

I think I'll make one up.... the Challenge et Marbella, 5 days in the hills of the costa.............yeh right, 5 days in the beach bar more like!!!
Like allot of these "Trans Events" they are rather woolly with the route details:

WHAT ABOUT THE REQUIRED TECHNICAL SKILLS?
The route generally follows small roads and paths. However, on occasion, like in the longest stages or when there is no alternative, quiet local roads will be used. The route has been designed to flow. There are some moderately technical sections within the route occasionally unless cycling trails, but these are mostly fun.

I wouldn't be too interested in bate'n up and down fire-roads for 5 hours each day... in that case id rather do the etape. The BC singletrack nirvana would be by far the best (most expensive) option.
No way man, no way.
