Hello Markus
You haved posed an interesting question. I believe exercise is imperative to our regaining our lost L/F.
For me, after a hospital stay, it usually takes a few days of complete rest to feel upto entertaining the thought of getting physical!
I also do my own home IVs to enable me to get home sooner. I asked my Chest Physician if I could continue to play tennis whilst the PICC line was in place. He said there was no reason not to. I play doubles and just avoid the net position, incase I'm whacked with a body shot to the PICC area. I have the PICC line inserted in my upper left arm, [I'm right-handed] The dressing is partially hidden by my shirt sleeve. I check on it often, have had no probs, whilst playing tennis. When I do my IV's, I check the site for tenderness. If it's unusually red and sore to touch I would suspect an infection and seek med advice.
I guess it's like so many CF issues, it's down to the individual person's choice of exercise. I would be a little wary of maybe playing a contact sport, like rugby, it would be a painful experience to have the line ripped out!!
If I can't play tennis, I opt for my stationary bike as another source of regular exercise.
Hey, it will be good to see if other's do any form of exercise while they have a PICC line. Walking up hill and down dale shouldn't raise any dangers......
Good luck at the gym.
Cheers
Eileen.
