Professor Hiro Kishimoto's research lab focuses on aging, physical activity, and health outcomes in older adults, with a strong emphasis on the interplay between physical function, mental health, and chronic conditions. The lab investigates the role of physical activity—particularly moderate-to-vigorous physical activity (MVPA)—in maintaining physical function and reducing the risk of poor health outcomes in community-dwelling older Japanese adults. It also explores biomarkers such as handgrip strength and sedentary behavior, using objective measures like accelerometers, to understand their associations with mortality and chronic pain. Additionally, the lab contributes to health informatics and data standards through work on grid computing and interoperable health data systems.

Impaired mental health status in the first semester significantly predicts an increased incident risk of poor academic performance during the undergraduate period.
Our findings suggest that handgrip strength levels in midlife and late life are inversely associated with the risks of all-cause and non-cancer death in the general Japanese population.
Normative values (mean, median, or decile) were yielded for MVPA, LPA, and ST based on accelerometer readings in a large sample of older community-dwelling Japanese adults. One-half of the subjects' waking time was spent being sedentary, and >70% of the subjects met the current PA guideline by engaging in MVPA.
Only greater moderate-to-vigorous physical activity (MVPA) was significantly associated with higher levels of PF variables in both men and women. Thus, time spent in moderate-to-vigorous physical activity (MVPA) can help older adults maintain or improve their physical function.
The Global Grid Forum (GGF) has embraced the Open Grid Services Architecture (OGSA) as the industry blueprint for standards-based grid computing. “Open” refers to the process used to develop standards that achieve interoperability. “Grid” is concerned with the integration, virtualization, and management of services and resources in a distributed, heterogeneous environment. It is “serviceoriented” because it delivers functionality as loosely coupled, interacting services aligned with industryacce
The number of chronic pain sites was positively associated with the presence and severity of neuropathic-like symptoms in community-dwelling older Japanese adults with chronic pain.
The aim of this cross-sectional study was to determine whether older adults who practice walking have a lower risk of physical frailty than those who do not. The study subjects were 846 older adults and were not certified as needing support or nursing care. The subjects were classified as being physically frail or pre-frail or being robust, according to the revision of the Cardiovascular Health Study criteria. We classified the subjects by questionnaire into a no-exercise group, walking-only gro
The effects of sleep duration and quality on physical frailty may differ. We examined the association between sleep duration/quality and frailty phenotype according to frailty components. This cross-sectional study analyzed 848 community-dwelling Japanese adults aged 65-75 years (mean age 70.8 yrs, 50.1% women) without long-term care needs. We classified the participants by their sleep duration: short-, middle-, and long-sleep groups. Sleep quality was assessed using the Pittsburgh Sleep Quality
Our analyses did not reveal a synergistic effect of depressive symptoms and sleep disturbance on chronic pain and its severity, suggesting that most of the effects of depressive symptoms on chronic pain may be mediated by sleep disturbance.
