Two articles on PainSci cite Robergs 2012: 1. Does Massage Therapy Work? 2. A Deep Dive into Delayed-Onset Muscle Soreness
PainSci commentary on Robergs 2012: ?This page is one of thousands in the PainScience.com bibliography. It is not a general article: it is focused on a single scientific paper, and it may provide only just enough context for the summary to make sense. Links to other papers and more general information are provided wherever possible.
Concise, clear summary of the lactic acid myth, by a physiologist, in a journal. This is the single best professional source citation I know of on this topic.

There is no ‘evil' to muscle lactate production. As there is no clear evidence that lactate has any direct negative effect on muscle contraction, there is also no ‘conundrum' to muscle lactate. Muscle lactate production is essential to sustained, repeated intense muscle contraction. Post-training increases in MCT1 and MCT4 support greater rates and total capacities of muscle lactate efflux during intense exercise performance, thereby allowing for a greater capacity for muscle lactate production and related glycolytic ATP turnover. It is long overdue, based on all aspects of the scientific method, to recognize muscle lactate production as a benefit to intense exercise performance and muscle biochemistry. I encourage researchers and educators alike to present an interpretation of muscle lactate production where the evidence-based view of the benefits of lactate production are espoused rather than a traditional blame of fatigue and acidosis simply because that is how it has always been.
