For women over 65, doing online dance classes with thigh bands that partially restrict blood flow improves leg strength more than dance alone, as shown by being able to stand up from a chair 3 more times in 30 seconds after 12 weeks.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether combining BFR with online dance consistently improves lower limb strength across diverse populations of older women, accounting for variations in cuff pressure, dance style, and adherence.
A systematic review and meta-analysis of all randomized controlled trials comparing online dance with and without BFR in women aged 65+, using standardized protocols for cuff tightness (e.g., 7/10 perceived pressure), dance duration (≥12 weeks, 2x/week), and outcome measures (30STS, CRS), with pooled effect sizes and heterogeneity analysis.
Whether BFR added to online dance causes greater strength gains than dance alone in older women, with blinding, larger sample size, and standardized occlusion pressure.
A double-blind, placebo-controlled RCT with 100+ women aged 65–80, randomized to either online dance with active BFR cuffs (7/10 tightness) or sham cuffs (no occlusion) for 12 weeks, 2x/week, measuring 30STS repetitions, CRS, and thigh muscle volume via DXA as primary outcomes.
Whether long-term use of BFR-enhanced online dance is associated with sustained strength gains and reduced functional decline in community-dwelling older women over 2 years.
A prospective cohort study following 300 women aged 65+ who choose to participate in BFR-enhanced online dance vs. those who do not, measuring 30STS, CRS, and mobility scores annually for 24 months, adjusting for baseline activity, comorbidities, and adherence.
Whether women who experienced fewer falls over 12 months were more likely to have previously used BFR-enhanced dance programs.
A case-control study comparing 50 women aged 65+ who had ≥2 falls in the past year to 50 matched controls with no falls, retrospectively assessing prior participation in BFR-enhanced online dance over the prior 12 months.
Whether current users of BFR-enhanced online dance have higher lower limb strength than non-users at a single point in time.
A cross-sectional survey of 500 community-dwelling women aged 65+ measuring current participation in BFR-enhanced dance and concurrent 30STS performance, controlling for age, BMI, and physical activity history.
