Skeletal muscle function and vitamin D
タイトル(掲載誌)The Journal of Medical Investigation
一般注記Age-related changes in muscle strength and physical functions, and the association between vitamin D status and skeletal muscle functions were investigated in 36 men (21-90 years old) and 52 women (21-104 years old). Significant ageing-related decreases in several skeletal muscle functions and serum 25-hydroxyvitamin D [25(OH)D] levels were observed in both men and women. Cut-off values for the Timed up and go (TUG) test, walking speed, handgrip strength and Barthel Index (BI) detecting walking difficulties in the receiver operating characteristic (ROC) analysis were 11.1 sec, 0.60 m / sec, 17.0 kg, and 90.0 in males, and 28.6 sec, 0.43 m / sec, 13.9 kg, and 67.5 in females, respectively. By comparing personal present data of muscle strength with these cut-off values, people can easily understand their process to walking difficulty. Therefore, these results are important and useful to avoid or to delay a handicapped and dependent status by improving the vitamin D level, rehabilitation and nursing care.
