The average age of the participants in the LIFTMOR was 65, with std deviation of 5, which means very few of them were over 70. They were screened to make sure they were functionally healthy, which excluded a lot of weaker people.
Potential participants were excluded if they had:
(1) Uncontrolled cardiovascular or respiratory disease (2) Recent fractures (within the past 12 months) or severe localized back pain (3) Neurological or physical conditions that would prevent them from safely doing heavy resistance training (4) Active malignancies (5) A history of taking medications known to actively harm bone health (like chronic corticosteroids)
"The LIFTMOR trials used 85% of each person's 1-rep-max." Correct. There is no "standard" for "heavy". Unfortunately, for most people (esp women) who are over 70, 85% of their 1-rep-max will not likely be heavy enough to stimulate bone growth. So they will not be able to provide enough stress on their bones to increase their bmd.
If 85% of your 1-rep-max is heavy enough to stimulate your bones, that is great. I am just speaking from my experience with a lot of women over 70.
Plus how many people have access to a LIFTMOR/ONERO-style full-supervision for every session from a PT?
I am sorry you already fractured your mid-back. Dead-lifts are very dangerous to do with a pre-existing fracture to your mid-back. Most PTs would not allow their patients to do them. Exposing oneself to the risk of vertebral fractures is like playing Russian roulette. There are several people in this forum who have talked about the excruciation pain and disability that can be caused by a vertebral fracture.
I know a lot of people hate taking drugs but one cannot deny these results:
Evenity: Vertebral fractures: ≈73% decrease
Tymlos: Vertebral fractures: ≈86% decrease
Forteo: Vertebral fractures: ≈65% to 69% decrease
Prolia — Injected every 6 months: Vertebral fractures: ≈68% decrease
Reclast— Annual IV infusion: Vertebral fractures: ≈70% decrease
Fosamax — Oral weekly/daily: Vertebral fractures: ≈47% to 50% decrease
@roseincalifornia Whoa! I had a minor strain injury in my mid-back, not a vertebral fracture! My spine T-score is -0.9. It is my other bones/T-scores that put me into osteoporosis.
If all one is routinely lifting is a 1 lb can of soup, then bone is going to be degrading. Even if one's maximum lift is 10 lbs, then working out with a bit over 8 lbs should benefit your bones according to my reading of the study. It may not be enough to GAIN bone from lifting 85% of such a low 1RM weight. I do agree that a hypothetical person in that condition most likely needs the pharmaceuticals ASAP and needs the full supervision for any lifting.
I plan to start anabolic meds if I do not get enough benefit from HRT and lifting after 2 years when I would be 68. If my spine was -3.x then I think that I would start meds now. I am 10 months into the HRT + lifting and monitoring BTMs along the way. If my Bone Turnover Markers stop looking good then I plan to start the meds before 2 years is up.
