The host of benefits associated with over-under workouts includes improved lactate oxidation and clearance capacity, great expression of MCT enzymes, as well as improved tolerance of associated metabolic byproducts over threshold. We look at the established mechanisms behind these phenomena and find that over-unders, as well as lactate presence and oxidation itself, probably don't have a unique adaptation unavailable to other types of training. The follow-up episode, Ten Minute Tips #27, will di...

This episode is a coaching perspective on the upsides and downsides of when you just want to "set it and forget it." We cover pacing adjustments, mental state, fatigue and threshold feedback, and putting the "max" in VO2max intervals. Plus a couple scenarios where erg mode is an excellent tool.

Dr. Patrick Smith and Kolie sit down to discuss the athletic and coaching implications of Karl Friston's free energy principle of the brain, the right approach to bridge the gap between expectations and observable reality in training, and the right amount of sensitivity to this feedback. This dovetails with the appeal of quick fixes, miracle intervals, and silver bullet training principles. We also discuss what practical solutions are, setting yourself up for success, and your listener questions...

This episode investigates the scientific relationship between size and power (allometry), both vo2max and maximal strength and power, and what it can teach us about sound training methods. How do w/kg and w/CdA scale? Why can't gaining muscle add aerobic power? Why can FTP seem to drop when dieting? Why do we rebound from crash diets? Why do most Tour de France winners seem to fit a certain size and weight? We answer all these questions and more, plus your listener questions.

Does overtraining cause mitochondria to dysfunction? We look at data in the Flockhart study on excessive training and compare them to the headlines, a similar overtraining study using proteomics, and a published response to Flockhart. We break down mitochondrial function, what various measurement methods actually tell us, why your mitochondria are probably just fine, and why these studies raise more questions about mitochondria's role in overtraining (if any) than they answer. Finally, we answer...

After discussing "zone 2" definitions, we look at adaptations and dose relative to other training intensities, fatigue, and volume. We look at the relative necessity of endurance riding in both very low and high volume training, and answer listener questions, including if there's a lower limit for endurance pace.

Andy Coggan joins the podcast again to discuss everything we didn't get to in the previous episode. We get back stories behind the adaptations by training zones chart and the category and w/kg chart. We also go in depth with nitrate supplementation, vo2max training. if burning fat makes you burn more fat, if signaling studies translate to performance, and the nature of adaptation itself. There are plenty of pithy proverbs along the way.

In this episode, Andy Coggan discusses FTP and its context among various threshold definitions, the infamous "hour of power", and the legacy of Training And Racing With A Power Meter. We also discuss Andy's lack of social media presence, the chapters he's written on the history of exercise physiology, and delve into some topics in exercise metabolism including VLamax, substrate use at FTP, methods and interpretations of the lactate shuttle, and more.

Think your FTP is the power you can hold for 60 minutes? Think again! We dig into a classic Billat paper on time to exhaustion (TTE) and training threshold by adding time in zone. Then we discuss into the metabolic implications of these results, how they align with real world experience, and how this affects training and assessment of its effectiveness. Finally, we answer your questions as asked in Kolie's Instagram stories @empiricalcycling.

Should you always train like you race? In this episode we investigate three myths related to this idea, and find some grains of truth along the way. The myths are 1. Sprinters and non-sprinters really need to train aerobic systems differently. 2. Crit racers mostly need to focus on anaerobic efforts. 3. You won’t need to train FTP if you don't race time trials. We touch on some track sprinting as well, and of course answer listener questions from Kolie's instagram, so follow him there if you'd l...

We begin our foray into listener-submitted training myths, looking at the largest issues with the claims, and discussing why, as always, it depends. This episode's myths are: 1. Low cadence riding is strength training. 2. Burning more fat makes you better at burning fat. 3. You should do your base rides in the little ring.

While the phosphocreatine energy system is well known for sprinting, it also has another crucial role as part of the aerobic energy system. We delve into creatine's part in not only temporal energy buffering, but spatial too, and how cells are organized to support this and how badly organisms suffer without it. Then we look at more research showing that the aerobic recovery of phosphocreatine is highly correlated with repeated sprint power, and come to some practical conclusions we can make from...
