May impair K+ redistribution at high intensities; leaves open relevance to arrhythmia risk or exercise guidance in patients.
Does exercise intensity affect potassium balance in muscle and blood in humans?
High-intensity exercise leads to a rapid loss of potassium from exercising muscle to the circulation, with redistribution becoming less efficient at higher intensities.
Vøllestad et al. (1994) studied this question.
