Objective: The purpose of this study was to examine the effect of long-term training program combining increased physical activity and walking with blood flow restriction (BFR) on locomotive syndrome in elderly adults.
Methods: A total of 13 relatively active subjects (11 men and 2 women) aged 67.2±4.0 years were assigned to the increasing physical activity (walking and climbing stairs) group (CON-W, n=6) or blood flow restriction walk training group (BFR-W, n=7). Both groups performed more than 30-min walking training at a pace faster than usual for at least 3 days and climbed more than 5 flights of stairs per day for at least 4 days per week for 6 months. Additionally, BFR-W group performed a treadmill walking for 20 min once a week at an exercise intensity of 70-85 % of age-predicted maximal heart rate (HRmax=220 - age). Locomotive syndrome risk tests (stand-up test, two-step test, 25-question risk assessment) were performed.
Results: There was no main effect of group, time, and interactions between group×time in the two-step test, stand-up test, and 25-question risk assessment.
Conclusion: Long-term walking and stair-climbing training programs did not improve the outcomes of locomotive syndrome risk test in physically active elderly subjects.
