Jem Arnold is a PhD candidate at the University of British Columbia, where his primary research focuses on sport-related vascular conditions. Jem is a physiotherapist, a physiologist, and an avid cyclist and trail runner interested in optimising endurance training.

 

IN THIS EPISODE YOU'LL LEARN ABOUT:

-Including training above "threshold" in your program improves VO2max, but may not improve Time Trial performance more than training only up to threshold-intensity (a recent meta-analysis)

-Implications of these findings for athletes and coaches - what does it mean in practice? 

-How can we interpret group-level research for individual-level training programming and application?

-Why even big sample sizes and data sets might be of limited value for the individual - the larger the sample size, the greater the confidence in the "group mean", but individual prediction may still be way off

-What is the variability of heart rate, RPE, lactate, and muscle oxygen saturation from day to day?

SPONSORS:

FORM Smart Swim Goggles give you unprecedented real-time feedback in your swim training through a display on the goggle lens. See every split to stay on pace, track your stroke rate and don't let it drop, use heart rate to become more scientific and precise with your training (through integration with Polar HR monitors) and analyse more in-depth metrics post-swim in the app. You can also use a vast library of workouts or training plans, or build your own guided workouts. Get 15% off the goggles with the code TTS15 on formswim.com/tts. 

 

ZEN8 - The ZEN8 Indoor Swim Trainer is a unique Dryland Swim Trainer that allows you to improve technique, power, and swim training consistency. With the trainer you can do specific power and technique work, including working on your catch and core activation, and it helps you stay consistent even if you don’t have much time to train. You can try the Zen8 risk-free for up to 30 days, and you can get 20% off your first order on zen8swimtrainer.com/tts.
