I want to talk 'heat' real quick 🔥
If used sensibly, using heat as an additional stimulus in training can provide a real boost to your training. This can be done passively (eg., sauna, spa bath) or actively (using a hot training environment or adding layers when training).
Benefits include:
🌡 Improved thermoregulation (vital for hot race prep).
💪 Improved plasma volume and, subsequently, better oxygen delivery to the working muscles.
🫀 Lower heart rate at a given work intensity.
Another way in which heat can be used to optimise training is to increase the aerobic challenge for a given workout.
For example, I currently need to spend more time on an exercise bike than I'd like due to a chronic back/nerve issue. I typically struggle to elevate my heart rate on the bike, so I have started to use clothing layers to elevate my heart rate (pictured). Ultimately, the absolute workload (wattage) doesn't matter to me, just the aerobic workload (heart rate response). This approach can work as a gentle introduction to heat training.
Whilst I may look like i'm having a mid-life crisis riding alone on a spin bike in a dark corner of the gym, it may well pay off when I can get my running volume back to where it needs to be! 😅
Do you have any 'hot tips' for heat training? If so, i'd love to hear them!
