Q&A #11 - Should you use different heart rate zones for swimming, cycling and running?
Q&A #11 - Should you use different heart rate zones for swimming, cycling and running? According to Dr. Phil Maffletone, the aerobic threshold heart rate is the same in all aerobic sports (like swimming, cycling, and running). Is this true? How the type of athlete you are and your ability and experience in different sports impacts whether your heart rate zones will be similar or not between different sports. Practical examples from lab tests and research studies showing massive discrepancies in threshold heart rate between sports (we're talking 10-20 bpm differences) The problems with the MAF-formula or 180-formula for aerobic threshold heart rate.
