Q&A #33 - Incorporating bike or run commutes to work in training, and distinguishing between good and bad lower heart rate
Q&A #33 - Incorporating bike or run commutes to work in training, and distinguishing between good and bad lower heart rate How should you effectively incorporate bike or run commutes into your training to get training benefits without compromising quality in other key workouts? How does this change if you do both a regular workout and the morning bike/run commute? How should you think about nutrition around training in the morning and commuting to work? How do you distinguish between a reduction in exercise heart rate due to getting fitter versus being in a state of non-functional over-reaching?

Cycling movement quality and using the Leomo Type-R to assess it with Sebastian Weber | EP#180
Sebastian Weber is a sports scientist and highly successful coach, in both professional sports (having worked with athletes like Peter Sagan, Tony Martin, and André Greipel) and with age-group endurance athletes. He is also the co-founder of the physiological performance software INSCYD. In this episode we discuss cycling technique, quality of movement, and holding a good (aerodynamic) position, and how the LEOMO Type-R device can be used to improve these important but easily forgotten aspects of cycling and triathlon cycling. IN THIS EPISODE YOU'LL LEARN ABOUT: -The importance of quality of movement in cycling, and how it has become somewhat forgotten in a world obsessed with power. -The LEOMO Type-R device, and how it can measure quality of movement in a large variety of ways to help assess and inform training. -Examples of common issues regarding quality of movement and how to correct them -How to use the LEOMO Type-R to improve aerodynamics -How much should triathletes and time trialists train in the TT-position -Is the LEOMO Type-R a good investment for age-group triathletes?

Nike Vaporfly 4% - can these shoes really make you run faster? with Wouter Hoogkamer | EP#179
The Nike Vaporfly 4% running shoes are supposed to improve running economy by 4%. Wouter Hoogkamer, PhD, is one of the researchers who found out that this improvement is actually legit. What's more, he has researched how much faster that improvement in running economy could make you. In today's episode we discuss the Vaporfly 4% shoes, running shoes in general, running economy, breaking two hours for the marathon, and more. IN THIS EPISODE YOU'LL LEARN ABOUT: -The Nike Vaporfly 4% shoes, and how Wouter and his colleagues at the University of Colorado verified that they can reduce the energetic cost of running a given speed by 4%. -Running economy, and how improvements in it translates to improvements in speed. Slower runners may benefit more from the 4% shoes than faster runners. -Footwear in general, and the tradeoff between cushioning (which is good for running economy) and weight (which is bad for running economy) -The impact of drafting in running - how much energy can it save you? - SHOWNOTES: https://scientifictriathlon.com/tts179/ THAT TRIATHLON SHOW HOMEPAGE: www.thattriathlonshow.com SPONSORS: Precision Hydration - One-size doesn't fit all when it comes to hydration.

Polarised training with Stephen Seiler, PhD | EP#177
Stephen Seiler, PhD, is known for his research on how elite endurance athletes actually train. In this research, he discovered that most endurance athletes spend the majority of their training time (~90%) at very low intensities (below the first lactate/ventilatory threshold) with most of the remainder of the training time spent at high intensities (above the second lactate/ventilatory threshold), with little time spent in between. This training intensity distribution has become popularised and known as 'polarised training'. IN THIS EPISODE YOU'LL LEARN ABOUT: -What is polarised training, and what is the evidence behind it? -Polarised training and "pyramidal training" - the nuances of training for different kinds of endurance sports and events -Does polarised training work for time-limited age group triathletes? -How to set up your training zones and intensities correctly (and the dangers of short-cutting FTP-tests) -Triathlon-specific considerations with polarised training SHOWNOTES: https://scientifictriathlon.com/tts177/ THAT TRIATHLON SHOW HOMEPAGE: www.thattriathlonshow.com SPONSORS: Precision Hydration - One-size doesn't fit all when it comes to hydration.
