Exertional rhabdomyolysis (ER)
The warm weather is here and with it comes an increased risk of ER
Risks include the intensity, duration and types of exercises performed
One of the biggest risks is the exercise experience of the participants, both in those with little to no experience and in those experienced athletes less trained than their counterparts.
Multiple case reports find that intense novel exercises early in the preseason before getting acclimatized and “in shape” carry great risk to the participant. These can be summarized as “too much, too soon, too fast.”
Coaches need to be educated about this and be prepared to detect and effectively handle ER through an emergency action plan.
-Conditioning workouts need to be phased in rather than start at maximum intensity on day one.
Eccentric exercises appear worse than concentric exercises.
Has been seen in almost all sports, ranging from swimming to golf.
It’s not just preseason football!
High humidity and high temperature environments increase the likelihood of ER
Males are more vulnerable to ER than females
Increased risk with sickle cell trait and glycogen storage diseases
Multiple drugs may increase individual risk including alcohol, cocaine, amphetamines, MDMA and caffeine.
Implicated medicines include, salicylates, neuroleptics, quinine, corticosteroids, statins, theophylline, cyclic antidepressants and SSRIs
