I thought this group might enjoy seeing the effects of an abrupt decline in training. I'm 2.5 weeks out from hip replacement. My training has been getting poorer in the past 6 months as the hip made running slow , painful or impossible and occasionally made cycling not much fun either. Once I picked an OR date my motivation to suffer on the trainer in the winter has been poor. Nonetheless I managed to keep training with more upper body weight training. A typical week was 90 min str, 2 hours swimming and 4 hours indoor cycling, plus lots of dog walks. I know I could have / should have swam more, but but but.

Anyway, according to the Garmin, my pre op my resting HR was 42-43 bpm, HRV, 44 ms. After just 2 weeks of sitting around and not even walking much my resting HR goes to 51, HRV down to 35ms, and I gained 5 pounds! I'm very happy to be able to get back on the trainer just this week. I'm only able to spin at low effort up what was to my zone 2 level and I'm 20-30 watts lower based on my RPE and breathing. I'm planning 2 more weeks of steady trainer work and MIGHT ride outside in 2 more weeks. It'll depend on if I can get onto the bike without a step stool and if I keep having not much pain in the new hip.

so detraining is real. But I plan on being back in shape for the the summer.
