Supplement cuts muscle loss in knee replacements - Science Daily,
10/25/13 - "Twenty grams of essential amino acids
taken twice daily for a week before and for two weeks after knee-replacement
surgeries helped 16 patients, mean age 69, recover faster and with much less
muscle atrophy than a control group ... 12 members of a control group
receiving 40 grams a day of a non-essential amino acid supplement, a
placebo, averaged an 18.4 loss in quadriceps muscle mass in their operated
leg six weeks after surgery; those getting the supplement of eight essential
amino acids (EEA) averaged a 6.2 percent loss. Eighty percent of atrophy
occurred in the first two weeks after surgery. Atrophy in non-operative legs
was about 50 percent of that in the operative leg in both groups ... The
functional measures that we looked at -- getting up out of a chair, going up
a flight of stairs and going back down the stairs -- were all back to
baseline in the treatment group ... a mix of histidine, isoleucine, leucine,
lysine, methionine, phenylalanine, threonine and valine"
Put Those Shoes On: Running Won't Kill Your Knees - NPR, 3/28/11 -
"We know from many long-term studies that running
doesn't appear to cause much damage to the knees ... When we look at people
with knee arthritis, we don't find much of a previous history of running,
and when we look at runners and follow them over time, we don't find that
their risk of developing osteoarthritis is any more than expected ...
exercise, including jogging, may even be beneficial ... exercise appears to
stimulate cartilage to repair to minor damage. It could be that the impact
of body weight when the foot hits the ground increases production of certain
proteins in the cartilage that make it stronger, he says" - Note: I
run six miles per day three times per week and swim three times per week.
I've never had knee problems. Even my doc seems confused that I don't.
