Can pool running give me the edge?

Hi guys, 

Currently recovering from medial tibial stress syndrome. But taking the time out to learn more about the science of running and be a smarter runner on my return.

I was running about 35mpw before I got injured. I'm going to follow a training plan from my coach when I return so that side of it is covered- I'm just wondering whether anybody on here boosts their fitness using swimming or pool running? My physio said if you do pool running with weights it can get the HR very close to what it would with running- to me this sounds like it could be a way of getting my fitness back quicker safely as it doesn't involve the impact? Especially as when I'm coming back I'll have to build back up to 6 runs a week from 2-3 with lots of rest days in between.

When my physio advises I will add it into my rehab treatment but as for when I'm back training properly again- I'm just wondering if I'll get any benefits by adding in a session or two in a week as well as my 6 runs? Is it safe to do this? I've heard it's low impact so should be fine but wanted to check as don't want to damage myself! Anything I can do to build speed safely would be great.

Hi blackdonkey, I was doing water running as I've been recovering from a bad achilles, longest session I did was 45 mins, and this was after cross training in the gym.  I didn't use weights, and the water only came up to my chest so I had to run along the bottom.  However, I did try to keep my legs moving the same way as they would when I run...try to avoid a cycling motion!

As to whether it will build up your running fitness would probably depend where you are now.  If you already have a good baseline, then I doubt it, but it will help you maintain the fitness levels you have.
