ABSTRACT

Japan is the only country that has implemented a nation-wide measure for functional disability leading to long-term care needs in old ages. Thus, there are no previous national trials that we can refer to. Whether its disability prevention measure succeeds or not will depend on our own efforts toward the future. In this paper, I will overview a 10-year experience with the disability prevention program launched in 2006, and then will point out the relevant issues in realizing the prevention of functional disability in old ages for exercise and sports scientists.

ABSTRACT

Physical performance measures, such as gait speed, one-legged stance and hand-grip strength, are known as assessment measures of motor function and predictors for adverse health outcomes, and widely used for assessing motor function in preventive programs for long-term care or screening of frail elderly. However, there is no standard assessment sheet for feedback of the results. In the present study, an assessment sheet on physical performance measures for community-dwelling older adults was developed. A pooled analysis of data from six cohort studies, including urban and rural areas was conducted as part of the Tokyo Metropolitan Institute of Gerontology Longitudinal Interdisciplinary Study on Aging. The pooled analysis included cross-sectional data from 4683 nondisabled, community-dwelling adults aged 65 years or older. Quintiles were derived according to age and sex group for six physical performance measures, i.e., hand-grip strength, one-legged stance, and gait speed and step length at both usual and maximum paces. The assessment sheets, which indicated the physical performance level according to age and sex, were developed by fitting third order polynomial curves to the data. The reference values in the present assessment sheet were considered to be derived from better represented community-dwelling older adults by using more large-scale population-based cohort data than that in the previous study. The assessment sheet should be useful for feeding back results on physical performance measures to elderly individuals and help them better understand their own physical performance levels.

ABSTRACT

BACKGROUND: This study was done to evaluate the validity and reliability of the Kaigo-Yobo (K-Y) checklist in the Korean elderly population. METHODS: The study population included 283 men and women over 65 years who visited the three community senior's welfare centers located in Seoul and Gyeonggi province from March 29, 2011 to May 26, 2011. The Korean frailty index (FI), Japanese K-Y checklist, Cardiovascular Health Study frailty index (CHSFI), activities of daily living, and Korean Mini-Mental Status Examination were completed for each participant. Reliability was tested by internal consistency (Cronbach's alpha), as was the test-retest reliability, at a 2-week interval. Validity was tested by the area under the curve (AUC) from the receiver operating characteristics curve as a predictor of frailty according to the CHS criteria and the validity index estimated by the reliability index. RESULTS: The correlation coefficients between Korean FI and K-Y checklist, Korean FI and CHSFI, and K-Y checklist and CHSFI were 0.61, 0.43, and 0.44 respectively. The range of Kappa value for each item on the Korean FI was 0.28 to 0.60 and 0.19 to 0.65 for the K-Y checklist. Cronbach's alpha for the Korean FI was 0.58 and 0.64 for the K-Y checklist. The AUC for the Korean FI was 0.79, and 0.64 for the K-Y checklist. The validity index for the items on the Korean FI ranged from 0.28-0.53 to 0.60-0.78 and 0.19-0.44 to 0.65-0.81 for the K-Y checklist. CONCLUSION: The K-Y checklist is a valid and reliable instrument to measure frailty in the Korean elderly population. Follow-up studies are needed.

ABSTRACT

Background: High heart rate (HR) has been associated with an increased risk of cardiovascular disease and mortality due to all causes. The present study was conducted to examine the effect of exercise adherence on longitudinal changes in resting heart rate among a population of community-dwelling elderly.Methods: The subjects were 133 men and 209 women aged 65 and older who participated in a baseline survey in August 1992 and were subsequently followed annually for 8 years. Resting HR was measured in the sitting position. The independent variable was the longitudinal change in differences of HR (Δ) from 1996 to 2000. Dependent variables were age, heart rate, smoking habit, TMIG index of competence score, and states of exercise adherence during the period 1992-1996.Results: Multiple regression analysis showed that heart rate in 1996 and smoking in men, and heart rate, TMIG index of competence score, and exercise adherence during the period 1992-1996 in women were significantly associated with longitudinal change in HR.Conclusion: Exercise adherence reduced the increase in HR of elderly women. These results suggest the importance of exercise adherence in elderly women.

ABSTRACT

Using atomic absorption spectrophotometry, we measured serum mineral (Fe, Cu, Z n, Mg, Ca, K, Na) concentrations in blood of male athletes participating in a triathlon competition held at Nakajima, Ehime in 1989. The athletes were divided into a young group (n=9, 24.2±3.6 yr) and a middle-aged group (n=9, 49.3±4.4 yr) . Blood samples were taken on the day before the competition, at the finish, on the following day and for eight days after.<BR>Immediately after the race, the concentrations of iron, calcium and potassium were increased significantly in sera taken from both groups, and those of copper and zinc were found to be increased only in the young group. In the middle-aged group, serum magnesium and sodium concentrations were decreased significantly. On the day after the race, most of the serum mineral concentrations had returned to values similar to those measured before the race, although the serum sodium concentration in the middle-aged group was still below the previous value, and this low level persisted for eight days after the race in both groups.<BR>Noticeable differences between the young and middle-aged groups were that recovery of increased iron concentration in serum tended to be prolonged in the middle-aged group, and the concentrations of serum copper and zinc were higher than those in the young group throughout the measurement period, with only small changes evident before and after the race. By contrast, serum potassium concentration in the middle-aged group was lower than in the young group throughout the measurement period.
