it looks like it has potnetial however I'd be skeptical about a couple of things with it.
1. they use a crushing mechanism to induce injury which may be different to the kind of injury occuring during climbing.
2. They measure cell counts not necessarily tendon recovery/strength etc.
3. The errors are a bit high and the +/- error of the treated group overlaps that of the untreated group.
Having said all of that it looks quite promising I think for climbing purposes a slightly different injury mechanism would be good and bigger groups to decrease error.
