Believe me you will know if you go past threshold (zone 4) and start to increase oxygen debt. While you can stay there for some time, this would not be sustainable day in day out. "Anaerobic" is a difficult term to understand and even more confusing when used for an HR Zone. You will generate some energy anaerobically at all but the gentlest paces. The issue is whether you can aerobically deal with the products so that they do not accumulate. This happens in phases. "VO2 Max" is the output beyond which this is impossible and is working very hard indeed. But there is the whole of zone 4 when we manage to maintain the byproduct levels but at increasing levels. As such i don't like to use the terms. Yes 500 or shorter distances at close to maximum are "anaerobic", but it has been estimated that even in the painfest that is an all out 2k around 80% of the energy is produced aerobically. The assumption on this forum is that people want to approach their optimum rowing performance. But some people just want to stay healthy even if not as fit as they could be. As such, if you are happy with the results of your rowing and it is sustainable, that is fine. Don't obsess with the numbers beyongd what makes the rowing more meaningful to you.cakeman wrote: ↑July 26th, 2024, 11:34 amI absolutely just followed 220-age and ran with it. I'm not so much obsessing over needing to hang out in Zone 2 as a number, more that I'm trying to (terms I dont 100% understand incoming) get both Aerobic and Anaerobic and as I (barely) understood it, a convenient measure is heart rate. I also wasn't sure that spending 3-5 days a week hanging around at my (perceived) max HR would be a 'good' thing, especially as a newbie to regular cardio.
Yeah, I figured that 30 mins wasnt a long row.. I'm kinda stunned looking at what some folks on here, reddit or generally will do, haha. Its also what I can get away with during my lunch break and if I set it into a habit for myself, I may get off my butt and start doing longer pieces at home.
You will have realised that 220-age is not respected here and can be very misleading, I would forget it. What you need to do is associate a given HR at a certain point with its consequences. What the number is is not relevant. But measuring HR will help you to see if you are progressing to faster paces than your fitness improvements warrant before you become over fatigued. It will also allow you to adjust your pace to account for low grade illnesses, tiredness, strain, different conditions etc. As I have said I struggle a bit with RPE. What appears hard at the start often seems much easier on tired muscles at the end, so I don't trust it. Maybe I have higher endorphin levels (the natural painkillers our body produces during exercise). But many are good at assessing how hard a session is by perceived effort alone. Certainly perceived effort after the same amount of work is a much better measure, but is difficult to implement, so I use HR.
Far too much from me already. Just make sure whatever you do you enjoy. Following advice that makes you dread rowing will only end wit you doing less of it.
