I had a recent asthma checkup where I was given a spirometry test. I blew into a device connected to a computer which measured the amount and speed of air I could expel from my lungs (peak expiatory flow). The nurse said my lung age was 55, but I’m 39. I was right at the bottom of the average range.
I have been off my bike for the last two years because I’ve got two young children. I’m at the beginning of a return to fitness using Trainer Road and the very occasional outdoor ride. Before the kids came along, I’d cycle ten to fifteen hours a week and I’d always assumed I had a good cycling physiology as I could beat my club mates up most hills and in the sprint back home.
Do you think lung age/lung capacity decreases/increases dramatically with fitness? Has anyone had spirometry test results improve markedly after getting fit? It was all a bit depressing to be told it was 15 years above my chronological age. My BPM was around 40 BPM when I was fit, so could that compensate for smaller lung capacity?
