Wondering if anyone has had any experience of rhabdomyolysis with ME work being a possible contributing factor. I recently cut short an FKT fastpack attempt 50 miles in after my urine had become like red wine. A little scary at the time as I feared rhabdo but it cleared up by the morning. During the run I had a constant sensation of needing to urinate with nothing much being produced. It was a hot day but I felt I was well hydrated and the effort in and of itself wasn’t overly severe (mostly powerhiking with a 7kg pack). I had taken an Nsaid the day before for a cricked neck. I’m now wondering if an ME Workout leading up to the run might have also contributed. I did one of the ME home workouts a week before the run with lots of split squats/squat jumps etc… which left me pretty sore for about 4 days. I’m waiting to have a blood test fof kidney function and my physician suspects maybe mild rhabdo but having done a bit of reading it looks like intense eccentric exercise can be a cause of rhabdo. There is even something called ‘squat syndrome’. I’m interested if anyone has any experience of this. Going forward I think I will avoid scheduling any ME work too close to my goal event…
