Key result

Aerobic training plus blood flow restriction enters feasibility testing versus standard care in T2D.

Why the study?

Aerobic training enhances cardiorespiratory fitness in type 2 diabetes, and combining it with blood flow restriction may enhance fitness more than standard aerobic training, but its feasibility and effects in individuals with type 2 diabetes remain unclear.

Does aerobic training combined with blood flow restriction improve feasibility, cardiorespiratory fitness, and glycemic outcomes compared to standard aerobic training in adults with type 2 diabetes?

Population

60 adults with T2D (n = 30 female)

Comparison

6 weeks of AT+BFR vs standard care AT (AT-stdCare)

Design

Single-blinded multisite randomized clinical pilot trial

Follow-up

6 weeks

Discussion

Member takes

Implication

Clinicians should not adopt BFR with aerobic training in type 2 diabetes yet; this pilot leaves open feasibility and preliminary efficacy on cardiorespiratory fitness.

Key Points

The trial aims to assess the feasibility of a 6-week aerobic training combined with blood flow restriction in individuals with type 2 diabetes and estimate preliminary effect sizes on health outcomes.
Single-blinded, multisite, randomized clinical pilot trial
Sixty adults with type 2 diabetes randomly assigned to AT+BFR or standard aerobic training
Both groups undergo supervised treadmill walking three times weekly
AT+BFR group uses blood flow restriction cuffs during exercise
Primary outcomes focus on recruitment and adherence, with secondary outcomes measuring cardiorespiratory fitness and glycemic metrics.
Feasibility metrics including recruitment and retention rates will be tracked
Expected improvements in cardiorespiratory fitness and glucose levels will be estimated
Pilot data will inform sample size for future studies.

Structured PICO

Does aerobic training combined with blood flow restriction improve feasibility, cardiorespiratory fitness, and glycemic outcomes compared to standard aerobic training in adults with type 2 diabetes?

Population

Adults with type 2 diabetes (T2D)

Intervention

6-week aerobic training combined with blood flow restriction (AT+BFR) consisting of supervised treadmill walking 3 times per week (96 min/week) at 40-50% heart rate reserve with BFR cuffs inflated to 60-80% of limb arterial occlusion pressure

Comparator

Standard care aerobic training (AT-stdCare) consisting of supervised treadmill walking without BFR

Outcome

Feasibility (recruitment, enrollment, adherence, and retention)

This study protocol outlines a pilot trial to evaluate the feasibility and preliminary efficacy of adding blood flow restriction to aerobic training for improving cardiorespiratory fitness in adults with type 2 diabetes.
