FRIDAY, Oct. 15 (HealthDay News) -- Strength training may help
kidney disease patients live longer and healthier lives, according
to a new study.
This discovery comes from researchers at the University of
California at Los Angeles, who studied the effect that lean and fat
body mass had on the health and survival of 792 dialysis patients.
Over five years, the researchers measured the participants' mid-arm
muscle circumference (a measure of lean mass) and their triceps'
skin fold (a measure of fat mass), and found that patients with the
largest mid-arm muscles scored higher on a mental health test and
lived longer than those with the smallest mid-arm muscles.
In fact, participants with the highest mid-arm muscle
circumference were 37 percent less likely to die than those with
the lowest circumference, reported Dr. Kamyar Kalantar-Zadeh, of
the Los Angeles Biomedical Research Institute at Harbor-UCLA
Medical Center, and colleagues.
The link between triceps' skin-fold measurements and patients'
health and survival wasn't as strong, he added.
The results suggest that dialysis patients may benefit from
pumping iron or taking other steps to increase their lean body
mass, the researchers noted.
More studies are needed but "it is possible that interventions
that can improve muscle mass or increase lean body mass can lead to
better clinical outcomes and greater survival in tens of thousands
of dialysis patients and probably millions of individuals with
other stages of chronic kidney disease or other chronic disease
states," they concluded in a news release from the American Society
The study appears in an upcoming issue of the
Clinical Journal of the American Society of Nephrology.
