 note = {Background: Recently, we reported that blood flow-restricted（ BFR） training using elastic bands for resistance may be an effective home-based resistance training program for promoting muscle hypertrophy. However, the effects of elastic band resistance training with BFR on muscle size and arterial function remain poorly understood.
　Purpose: To examine the effects of low-load, elastic band resistance training with BFR on muscle size and arterial stiffness in older adults.
　Methods: Healthy older adults（ ages 61-85 years） were randomly divided into BFR resistance training（ BFR-T, n = 9） or non-BFR resistance training（ CON-T, n = 8） groups. Both groups performed low-load arm curl and press down exercises（ four sets, respectively） using yellow or green bands（ Thera-Band）, 2 days/week for 12 weeks. The BFR-T group wore elastic cuffs（ width: 30 mm） around the most proximal regional of both upper arms during training, with incremental increases in external compression starting at 120 mmHg and ending at 270 mmHg. Observations before（ pre） and 3-7 days after（ post） the final training session were: MRI-measured muscle crosssectional area for upper arm（ CSA）, maximum voluntary isometric contraction（ MVC）, cardio-ankle vascular index testing（ CAVI）, ankle-brachial pressure index（ ABI）.
　Results: Elbow flexion and elbow extension MVC（ 7.8% and 16.1%） were increased（ P < 0.05） in the BFR-T group, but not in the CON-T group. In CAVI and ABI testing, there were no changes between pre- and post- results in both the BFR-T.
　Conclusion: In conclusion, low-load, elastic band resistance training with BFR improves muscle CSA as well as maximal muscle strength, but does not negatively affect arterial stiffness in older adults.},
