Effect of elastic-band-based resistance training on leg blood flow in elderly women
Bibliographic record
Abstract
The age-related decline in basal limb blood flow appears to be related to the pathogenesis of metabolic syndrome, noninsulin-dependent diabetes, and cardiovascular disease. Resistance training improves basal limb blood flow and vascular conductance in middle-aged men and women, but it is unknown whether similar vascular effects of training occur in the elderly. This study aimed to examine the effects of a 12-week progressive resistance training program using elastic bands on basal leg blood flow, vascular conductance, and functional performance in postmenopausal elderly women. Sixteen healthy postmenopausal females (age, 67 ± 5 years) were randomly assigned to a control (n = 8) or resistance training (n = 8) group, where they underwent 2 supervised strength sessions per week for 12 weeks. Prior to and at completion of this 12-week period, functional and strength performance and leg haemodynamic responses were measured. The training intervention produced significant increases in basal leg blood flow (31%), vascular conductance (34%), and a significant reduction in cardiac work (i.e., rate pressure product) at rest, as well as significant improvements in the 3 functional ability tests performed (30-s bicep curl, 30-s sit to stand, and back scratch). Haemodynamic or functional performance responses were not altered after the 12 weeks in the control group. This study demonstrates that a resistance training program using elastic bands elicits significant improvements in basal leg blood flow in postmenopausal elderly women.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
