Lung volumes

Starting to recover from the post competition blues and finding motivation to train again. I made a crude device for measuring lung volumes. In essence, it is a bucket, to which I poured water in 0.5l at a time and marking a "scale" on the side of it. It is then filled with water in the pool and you use a hose to fill it with air. In theory, how high the bucket raises from water, is your rought lung volume. Of course it's not very accurate, but it should be within the right ballpark.

I measured about 6.5-7 litres without packing and 9-9.5l with packing. If you consider the weight of the bucket, you could perhaps add another 0.5-1l there, so let's say:
7-7,5l without packing
9.5-10l with packing

I was actually expecting more, but still, that's a pretty good sized lung. Of course we're not talking about TLC, since this does not take into account the residual volume.

It felt good to be in the water again, and I managed a 7:00 static, which is good considering how little I've been training lately...
