Chronic obstructive pulmonary disease (COPD) is one of the leading causes of death in the United States and results in a significant reduction in lung function and exercise tolerance. In addition, there is a significant decline in muscle mass and strength in these individuals. Unfortunately, other comorbidities associated with this disease such as osteoporosis, osteoarthritis and obesity may prevent them from exercising at sufficiently high loads to promote muscle hypertrophy. Also, acute exacerbations may prevent them from performing exercise at all. Objectives: This brief review will discuss the potential benefits of using blood flow restriction (BFR) when combined with walking, resistance training and electrical stimulation in COPD patients and possible safety concerns. Design and Methods: Non-systematic review. Results: BFR improves muscle size and function when combined with low-intensity walking or low-load resistance training. This treatment appears to be safe and has been used by many different populations including individuals with ischaemic heart disease. For COPD patients who are contraindicated to perform exercise, a potential treatment may be to combine neuromuscular electrical stimulation with BFR. Conclusions: BFR appears to be a potential treatment for increasing strength and muscle mass for COPD patients when high intensity exercise may not be tolerated. In addition, BFR may provide benefits for COPD patients who are unable to exercise by combining it with neuromuscular electrical stimulation.

[Purpose] To test the hypothesis that toe grasping strength is associated with daily physical activity in older adults. [Subjects] Fifty-seven Japanese women, aged 52–78 years, volunteered. [Methods] Toe grasping and knee extension strength were measured. Physical activity was also measured, using an accelerometer, and the total duration of each level of exercise intensity (light, moderate, and vigorous) and average step counts were calculated. Subjects were separated into two groups on the basis of accelerometer-determined step counts: LOW (n=28, <8000 steps/day) and HIGH (n=29, ≥8000 steps/day). [Results] Body mass index and body composition (% fat and fat-free mass) were similar between the two groups. Absolute and relative toe grasping strengths (divided by body weight) were greater in HIGH than in LOW. However, both absolute and relative knee extension strength were similar between the groups. Relative toe grasping and knee extension strength correlated with all 3 intensities of physical activity and average step count. After adjusting for age, the duration of light plus moderate physical activity and average step counts correlated to toe grasping strength but not to knee extension strength. [Conclusion] Our results suggest that toe grasping strength may be associated with the amount of light intensity daily physical activity.
