Thank you for your kind comment 🙏

videos getting better 👌

I've not had any lab test. You ought to mention that you are talking about LT2. LT1 (the earliest spill of lactate into the circulation) is another a useful measure, the corresponding surrogate being the onset of breathlessness (BORG RPE 12).
Your fitness varies from day to so it's impractical to use lactate for training. Heart rate also has its problems for endurance training because cardiac drift needs to be taken into account. Even after a warm-up, my heart rate rises asymptotically reaching something near its final value at 60 minutes -maintaining full hydration.

John,
I think you are giving me a great idea for a future video 😄😄 LT1 is definitely a very useful measure. And true you don’t need a fitness test to be able to assess that one 😄
With cycling you can also take into account wattages to structure your training but when running I think heart rate and or speed corresponding to heart rate is the best way to structure your training.
How do you structure your training?

@@matsholvoet Most (nor all) of my training is bike-based and focussed on endurance. I primarily use perceived effort but make a note of my heart rate, which gives an idea of the day-to-day/long-term variations in fitness. For intervals, I use a power meter, calibrated from maximum heart rate and FTP.

The chemistry here is a bit iffy. Hydrogen is not acidic, the H+ ion from lactic acid is. And while the body does use lactate for energy (aerobically, when oxygen becomes available again) it's the anaerobic lactic acid synthesis from glucose that causes the burn.

Thanks for mentioning. I will have to grab my physiology book once more then 😄
