Lactate and its association with exercise has been known for more than 200 years after Jöns Jakob first observed it in the muscles of hunted stags. Consequently, knowledge of its relationship with exercise is deeply rooted in both popular culture and among endurance athletes. However, more recent research has demonstrated lactate’s presence during exercise has largely been misunderstood for much of this time. During this two part series, we do a deep dive into all things lactate to assess whether or not we should still be blood lactate testing cyclists, and whether there are better alternatives. So, before you decide to participate in a blood lactate test or recommend one for an athlete, you should definitely give these episodes a listen to make sure you are considering all the pros and cons. Or, listen for the myth-busting and rabbit holes this conversation necessarily gets into.
