[pct-l] to prevent injury

[Blanchard, Sym]

My bad.  I hit the send button accidentally.  Gotta love this iPhone keyboard.

The third paragraph should read as follows:


I do disagree with the notion that no published studies showing that wearing a hip belt can cause ankle injuries disproves the case .  Absence of evidence is not evidence of absence.  I doubt there has been funding or interest to specifically look at this issue, in particular affecting older hikers who just completed 2645 miles and whose support muscles may be fatigued.

I would think that ankle exercises on a half Bocce ball would be a better exercise to prevent ankle exercises than wind sprints.

Symbiosis

I agree that if you have to wear a heavy pack or if you have back issues, then a cinched hip belt would be a good idea.
However it is my opinion that this can also increase the chance of ankle injuries.

I think that trekking poles can help reduce this risk, but then there are the inherent disadvantages with poles (inefficient, cumbersome, tripping hazard...).   No such thing as a free lunch.

I do disagree with the notion that wearing a hip belt can not  cause ankle injuries proves

Thanks Melanie

The waist belt of backpack has  very important role to support heavy
load, as a result, the stress of spine is minimized.  If the total
pack weight is less than 10 kg, waist belt may be unnecessary. I just
pointed out no research may be exist concerning waist belt. But, it's
importance is very clear, so the many backpack makers never abolish
waist belt.

I have just write my blog : if you have a time, please see. I wrote my
blog in Japanese and English. I cannot write English properly but I
think better than Google translator.

My maximal total pack weight may be 38 kg or more:

I carried 20 days food ( for two persons 10 days ) and all the stuff,
and guided my wife South Lake to Lone Pine. We did not lose weight,
and suffered no injury.

Recently, I bought new backpack ( Altra 75 ) and tested at the
neighborhood Mountain. It worked well. I always carry backpack on the
hip bone, not on the shoulders.

for Tim, I think he may know himself.

He should work on rehabilitation as soon as possible. When his bone
became strong enough, he should train his muscle of lower legs. It is
necessary to reinforce his muscular strength and agility. Then the
possibility of injury becomes small.
