The Claim
In adults with sickle cell anemia, higher daily step counts are associated with an improved hematocrit-to-viscosity ratio, independent of hematocrit levels alone.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Adults with sickle cell anemia who take more steps each day have a better hematocrit-to-viscosity ratio, which reflects more efficient oxygen delivery in the blood, regardless of their hematocrit level.
See the scientific wording
In adults with sickle cell anemia, higher daily step counts are associated with improved hematocrit-to-viscosity ratio, a key indicator of oxygen delivery efficiency, independent of hematocrit levels alone.
When a person walks more, the flow of blood through small vessels gets faster and smoother. This pushes on the inside of the blood vessels, triggering them to release a chemical that makes the blood thinner and flow more easily. This happens even if the number of red blood cells stays the same.
What the research says
1 studyPeople with sickle cell anemia who walk more each day have thinner, flowier blood that carries oxygen better — even if their red blood cell count is the same as less active people. Walking helps their blood move more easily through tiny vessels.
