In your opinion, do we loose more plasma while riding for an hour, or weight lifting for an hour?biker-linz said:I think he means plasma volume. Reduced plasma volume (sweating etc.) = reduced pre-load = reduced stroke volume = increased HR.
What I meant rather is that if that extra workload placed on the heart actually help making it better adapted (bigger etc), can this be considered as a positive outcome? Bigger heart= increased stroke volume?biker-linz said:If what you mean is that the extra work the heart is doing will make it more econmical then I doubt it.
