Another steady 2x20 L3 session which didn't feel particularly comfortable after yesterday's exertions, if only I could have my old training zones back all would be well! :-)
Anyway, the session came and went and perhaps more importantly I did a repeat dehydration measurement during this session using the naked weighing technique, the results were, as always, fascinating. I really must start to do some much more serious work on the hydration front as I think it may be genuinely compromising my performance, particularly in the light of some of the publications I have been reading.
The results were as follows:
The total exercise time for the session was 80 minutes, including warmup and cool down.
Total fluid intake during session was 740mls.
Body weight loss during session was exactly 1.0kg.
Therefore total weight loss during session was 1.74kg
So, essentially during the 80 minute session I sweated out approximately 1740mls of fluid which is a fluid loss rate of 13mls per minute. Ok, so this is indoors but it's very much in line with previous tests I've done and indicates that I'm dehydrating at a rate of about one litre an hour.
Now, where's that bottle.
