Risks of cardio at elevated % of max HR

Training Q&A [Moderated]
1

Recently I’ve purchased a chest HR monitor for use with rowing on my erg. This is mostly just a curiosity for me and I mostly row on how I feel versus given HR zones.

I’ve noticed that towards the end of rowing workouts I’ll be at 170s and eventually bump into the mid to high 180s especially as I push myself over the last 500 to 1000 m

I am 36 so with Estimated max HR would be 184 with the obviously flawed equated of 220-age.

I recover fine from these workouts and do not feel any issues that I can sense. Is there any concerns where I would need to moderate my exertion?

Thanks!

While I don’t think that regular training at max or near-max heart rates improve cardiorespiratory fitness that much, as this is similar to always maxing out when lifting weights, I do not think it confers additional risk compared to a more moderate approach.
