The Best Exercise for Aging Muscles
'The toll that aging takes on a body extends all the way down to the cellular level. But the damage accrued by cells in older muscles is especially severe, because they do not regenerate easily and they become weaker as their mitochondria, which produce energy, diminish in vigor and number.
A study published this month in Cell Metabolism, however, suggests that certain sorts of workouts may undo some of what the years can do to our mitochondria.
Exercise is good for people, as everyone knows. But scientists have surprisingly little understanding of its cellular impacts and how those might vary by activity and the age of the exerciser.
So researchers at the Mayo Clinic in Rochester, Minn., recently conducted an experiment on the cells of 72 healthy but sedentary men and women who were 30 or younger or older than 64. After baseline measures were established for their aerobic fitness, their blood-sugar levels and the gene activity and mitochondrial health in their muscle cells, the volunteers were randomly assigned to a particular exercise regimen.'>>>

Because of one health problem after another over the past 10+ years, I've not been able to exercise properly and when I do, the results have been more than disappointing. And I'm talking about after 8-12 weeks of exercise and not getting the expected results.
I have several health conditions, and do, take them into consideration so I don't get too discouraged but I've been working at this for a little over a year now.
So thanks again. I'll show and discus this with my therapist and see if it might be of some benefit.
Oh, I'll be 62 in May so this comes at a good time. I hope. I'm tired of being tired and often bedridden no matter what I do. I was always so active.
Take care.
