A study knocking out HIF1alpha in mice reveals a counterintuitive relationship between markers of phenotype like fat oxidation, mitochondria markers, capillary density, and fiber type, and not having improved baseline performance. This uncovers an interesting relationship between the HIF pathway and oxidative metabolism, and how seemingly opposing adaptations are complementary.

This episode, seven Empirical Cycling coaches discuss their professional and personal experience with off season breaks. Balancing downtime and rest with fun and unstructured riding, plus some rules of thumb to make the most out of these potentially daunting times of the season. Then we answer a huge list of listener questions on whether sprinters can be good TTers, favorite workouts, coaching principles and athlete relationships, volume vs intensity, periodizing sprint training, lifting RPE, and much more.

Kyle returns to the podcast with balloon stories, but skip to 28:00 for the main topic of strength being a skill, and the training implications that this has. We discuss defining strength, goal settings, minimum effective dose for strength improvements, strength maintenance, tradeoffs with aerobic goals, individualizing strength programming, cycling specific programming and exercise choice, and many, many listener questions.

This episode we discuss Cole's evolution as a cyclist and our relationship between coach and athlete. From making lifelong friends in collegiate cycling, gaining over 100w of FTP, winning a national championship, realizing and encouraging agency as a coached athlete, balancing life priorities and the value of low stress environments, relationships with bodyweight and food, lifting weights, and much more.

We consider hypoxia inducible factor's muscular response to high intensity exercise before going more in depth in its effects with the next episodes. We break down high intensity training, defining hypoxia vs anaerobic, then dive into a study that investigates its main effects in high intensity execise, as well as individual variation in training response. Plus a couple practical tips for considering this pathway in training, as well as a peek at the adaptive tradeoffs we'll see in future episodes.

We discuss the dos and don'ts of trying new training methods. Whether or not you should try something new, setting a baseline, going all in on one thing, variables to adjust, finding a minimum dose, incorporating rest and fun, diets, vo2max and TTE blocks, and more, including your listener questions.

This episode we discuss the ten most common mistakes we see beginners make in their training plans, and their solutions. Goals and outcomes, learning the process, metrics and performance, specialization and individualization, training fads, balancing structure with fun, and more.

Retired professional road and cyclocross racer and newest Empirical Cycling coach Erica Zaveta joins to share wisdom from twenty years of competition and a decade of coaching. We discuss individualizing training for the high intensity disciplines of criteriums, cyclocross, and mountain biking, along with how and when to take mid season breaks, incorporating skills work, and adding practice crits and cyclocross practices to your program. Plus listener questions as always!

Kolie and Rory discuss their lists of the best things to do or avoid to maintain fitness in race season, and balance with appropriate rest. Also touched on are race prioritization, training and progression expectations, methods to estimate and manage fatigue, openers, volume vs intensity, and much more including your listener questions.

Coach and returning guest Marinus Petersen rejoins to discuss the pros and cons of different ways to quantify endurance and total training volume and adaptation. We consider TSS, total hours, and work measured in kilojoules, as well as coaching and programming aspects of endurance rides and balancing with interval sessions or races. We also answer your listener questions.
