Empirical Cycling Podcast

Delving into the biochemical depths of all life, Kolie discusses chemical equilibrium, or disequilibrium, and how ATP's high energy phosphate bonds aren't really what give it the energetic potential it's known for.

Today Dr. Helson runs the numbers on how much rotating weight matters when accelerating. The answer may (or may not) surprise you.

Whether we should pace endurance rides by heart rate or power is a training question where the usual answers lack sufficient depth. In this episode we provide enough context, and an alternative, that you might find the right style of riding for yourself.

In this highly anticipated episode, a scientific paper and some metabolic logic show us a simple, effective way to make your FTP training better.

This episode takes a look at things like power output and when we might find differences in training response. Most energy systems are touched on along with quick insights that will be expanded on in upcoming podcast episodes.

Are your friends using bro science? Do you know someone with a magic solution, who thinks they put together the whole puzzle with only half the pieces? Learn the warning signs! Kyle hosts this episode on how to recognize bro science, its rhetoric, and typical warning signs.

Oxygen is corrosive, but we need it for life and exercise. This episode looks at how free radicals are made in the body, their role in adaptation to endurance exercise, and the body's natural defense mechanisms.

The episode starts off with a primer on parts of muscle needed for contraction and how these relate to different methods of fiber typing (there's more than one!). We finish our look at a classic paper on cycling physiology and its sections on fiber type and substrate use. Then a paper on cross country skiers throws a bag of monkey wrenches into decades of established fiber type paradigms.

Do companies really make the best hydration mixes? They do, kind of, but they're expensive. It's difficult to adjust their mixes to flavor and your unique needs. This episode goes through a homemade drink mix that will probably hydrate you better, and definitely for cheaper, than anything on the market today. The recipe can be found on the website show notes at http://www.empiricalcycling.com/podc...

Kolie and Kyle look at the relationship between FTP and VO2max. We use data from a classic paper that calls into question the validity of a long-standing testing protocol in the scientific literature, which is still in use today.

The last month before your cyclocross season is a crucial one. In the new Ten Minute Tips series, Kolie looks at the elements of training you may want to incorporate to get a strong start to your season. Included are key workout types, how to manage intensity, incorporating running, and mixing technique work into training rides. Includes three example workouts.

We talk to Empirical Cycling athlete Emma Edwards for an in-depth race report about the 2019 Cascade Classic, where she was racing with Amy D Foundation. We talk about her top 10 on the GC, the gods of mechanicals, what it's like racing against TWENTY20, and her bike's gremlin... just don't get it wet, somehow, in the Pacific northwest.

One of the theorized benefits of low carb or ketogenic diets for cyclists is that it spares glycogen so it can be used when needed most. Kolie and Kyle walk through a paper investigating this question. They then discuss the upsides and downsides and potential utility of fat-adaptive diets in daily training.

The podcast's first deep dive into muscle physiology, we look at a study on weight lifting while endurance training vs just endurance training, with a surprising result. From here we talk about the size principle, which you're using a lot more often than you think.

MIT cycling team members Liam Fenlon, Berk Ozturk, and multiple time individual national champion Emma Edwards talk about collegiate nationals 2019, a 35 rider pileup, and how to put the "team" into the TTT.

FTP and Critical Power in theory measure the highest power output before significant fatigue occurs. We look at whether this is true, and the pros and cons of using FTP and CP.

Does going slow make you slow? Do you need to go slow to make you fast? We look into the reasoning behind two opposite training philosophies, then figure out what aerobic base really is, what's effective, and why.

We check out some old research to find the origins of common lactate myths like its role in fatigue, its acidity, the "anaerobic threshold," and whether it's a metabolic dead end. Then we correct the record with modern science while figuring out how smart scientists came to the wrong conclusions.

Kolie and Kyle sit down with The Fastest Pursuiter in the World, Ashton Lambie, and talk about gravel racing and training for the track, his world record individual pursuit, his time with Huub-Wattbike, and the aerodynamics of the mustache.

This episode begins with the mind-muscle connection of neural drive before diving into research on doing strength and endurance training concurrently, and how they interfere with each other. We then look at how the latest scientific research provides training solutions.

What do high intensity intervals, the original Tabata protocol, and a calcium leak have in common? Kolie and Kyle take a look at three scientific papers, what they might mean for you, and how to apply the conclusions to your training.

Kolie and Kyle look at how duration and intensity play a role in FTP training and the significance of the canonical 2x20min FTP workout. The discussion touches on how to structure workouts beyond 2x20, workouts for the time crunched and those with abundant time, and how to adjust workouts to account for TTE.

Bad news, everyone. You're training too hard for crits. Kolie and Kyle uncover the physiology of what makes someone successful at criteriums, cyclocross, and other types of repeated sprint performances. It's probably not what you think.

Kolie and Kyle take a deep dive into the pros and cons of the many FTP tests. "What is special about 60 minutes to the human body?" What tests should certain people avoid? How hard is it to ride at your FTP? 20 and 60 minutes, 8 minutes, ramp test, and variable-duration FTP tests as discussed here: https://www.trainingpeaks.com/blog/the-physiology-of-ftp-and-new-testing-protocols/
