Watts Doc #54: Glycogen's Effects On AMPK

This is a dive into research showing increased AMPK activation with low glycogen stores. We break down a paper discerning how AMPK does this, subsequent changes to AMPK's activity levels, and then come to some logical training conclusions. Along the way are some takeaways on interpreting and applying mechanistic research.

Our coaches Will and Giancarlo join the podcast to talk through their experience with cramps, and what's been done to attenuate them. We briefly discuss predictors of exercise associated muscle cramps as well as current theories about why they do occur, while most of the episode is spent on practical considerations, and the long list of potential solutions.

Taking enough rest can be intimidating if it's unfamiliar territory. Our resident philosophers of rest Rory and Maeghan join to take a deep dive into the most common reasons we see people being scared of sufficient recovery. We include plenty of practical takeaways for what to expect when resting, how much is too much, building new habits, knowing when you can get back into training, what not to do, and more.

Six of our Empirical Cycling coaches put their heads together to answer your questions on whether mid season breaks will set your fitness back to the dark ages, managing burnout and disappointment, if younger athletes can still overtrain, balancing intensity and volume, work and family stress, being a "good student" as a coached athlete, training habits, and things cyclists put an emphasis on that they shouldn't.

​Today we use Rory's recent post event slump to discuss strategies for refocusing and finding motivation again. This is mostly through the lens of goal setting and how to incorporate season planning, fun and unstructured riding, new disciplines, time with friends and family, being flexible, as well as listener questions on realistic goal setting, coping with not meeting goals, training vs racing motivation, and more.

Our very own coach James Mckay sits down to talk about the road to achieving his cycling career goal, a victory at the Lincoln Grand Prix. As this was his last race being coached by Kolie, they take a retrospective look at all the challenges and hard work that went into the last four years of training that made this such an incredible moment: volume, race specific intensity, cramps, heat training, race weight, pressure for results, and the unanticipated way it all came together.

After walking through the general structure and purpose of rest weeks, we break down the decision trees we use to plan rest weeks ahead of time, or what we look for to add them reactively. We also discuss using subjective metrics in rest week planning, plus if and when we wouldn't trust those metrics. Then we answer your listener questions, including mental fatigue, HRV and RHR, skipping rest weeks, accounting for soreness, and more.

We go deep into a couple papers that measure the relative contributions to early VO2max improvements, and the evidence about whether they're more are muscular or cardiac in nature, and what physiological differences there are with more well trained people. Moderate and high intensity training are contrasted, as well as the obvious shortcuts, plus a first-principles approach to alternative mechanisms. We also answer your listener questions on if you can screw up newbie gains, how much is just mental toughness, and more.

While the definition of a junk mile is still debated, we do our best to come up with a definition, analyze it in relation to training adaptations, and what should be done. We touch on volume, intensity, group rides, mental health, fatigue and security blankets, training camps, recovery, hyper-optimization, and lots more.

Our coaches Fabiano and Giancarlo join to discuss the balance between parenting and training, both from a coaching perspective and as parents themselves. We talk about finding vs making time, getting sick, guilt, managing expectations, partner and family support, challenges changing as kids get older, and much more.
