| Outline of Final Research Achievements |
We measured physical activity, body composition (muscle and fat mass), and muscular strength in patients undergoing chemotherapy for lung cancer to screen for sarcopenia and determine the effects of the measured variables on physical activity levels. Metabolic equivalents (METs) were measured daily from the start of chemotherapy to the following cycle. The muscle cross-sectional area of the upper arm was calculated by measuring upper arm circumference and subcutaneous adipose tissue thickness, and body fat percentage and handgrip strength were measured.
Our findings demonstrated that the patients spent most of their time performing low-intensity activities, suggesting that they had a limited range of daily activities. Our findings suggest that reduced muscular strength and increased body fat percentage induce inactivity. Thus, it is critical to encourage patients to consciously spend more time on activities to maintain their muscular strength.
