Abstract：
:The Tokyo Metropolitan Institute of Gerontology (TMIG) celebrates its 30th anniversary in 2002. Since its establishment, TMIG has been carrying out inter-disciplinary research on aging as a core institute in Japan and functions as a knowledge bank and a source for capable researchers of gerontology. The proportion of people aged 65 and above in Japan will reach 30% in the near future, which might be associated with serious medical, social, political, and financial problems. Because most developed countries will face similar situations in the near future, multidisciplinary studies in gerontology on a worldwide scale are necessary to solve the associated problems.

杂志文章,评审abstract：:The interrelationship between muscle strength, motor unit (MU) number, and age is poorly understood, and in this study we sought to determine whether age-related differences in muscle strength are moderated by estimates of functioning MU number and size. Eighteen older adults (OA; 67 ± 1.20 years) and 24 young adults ...
