“…The overall deterioration in test performance among the older age groups in the present study is in line with other studies (Aniansson et al 1983;Rantanen et al 1997), although the study designs and testing procedures were not exactly the same. In some tests (backwards walk, stair climbing and dynamic back extension) the younger subjects even improved their performance.…”

“…However, the present study still included subjects with chronic diseases and physically inactive lifestyles. Corresponding selection bias has been reported in other studies (Aniansson et al 1983;Rantanen et al 1997;Rantanen and Heikkinen 1998;Hughes et al 2001;Paterson et al 2004).…”

“…Previous longitudinal studies have reported selection of the study population to healthier and more mobile subjects (Aniansson et al 1983;Rantanen et al 1997;Rantanen and Heikkinen 1998;Hughes et al 2001;Paterson et al 2004). The selection bias will lead to underestimations of the performance and fitness changes with aging (Rantanen et al 1997), and will cause the population estimates of physical performance, if used as norm reference values, to be too high.…”

Purposes of the study were (1) to investigate changes in physical performance during 6 years followup among high-functioning older adults and (2) to describe the selection of study sample with reference to measured performance. Subjects (n=1,133) born during 1917-1941 participated in the battery of health-related fitness (HRF) tests (6.1-m walk, stair climbing, backwards walk, trunk side-bending, dynamic back extension, 1-km walk and body mass index) in 1996. Six hundred and six subjects were retested in 2002. In general, poorer fitness in the baseline assessment predicted non-participation in retesting as well as test exclusions and interruptions in retesting. The 6-year changes in the HRF showed a linear trend (P<0.01) according to age group: performance of older groups deteriorated on average more than the performance of younger groups. In most of the tests, gender was statistically significantly (P<0.05) associated with the changes in performance. The mean performance of the women deteriorated in all tests during the follow-up, while the mean performance of the men deteriorated only in the trunk side-bending, 6.1-m walk and 1-km walk tests. It can be concluded that among the subjects who participated in the followup testing, older age and being a woman increased deterioration in several components of HRF. Considering the selection of the subjects, the deteriorations identified are very likely underestimations of real fitness changes among this sample.

“…Other studies of change in muscle strength over time have shown declines (Bassey & Harries, 1993;Rantanen et al, 1997), no change (Greig et al, 1993), or even gains (Bassey & Harries, 1993;Rantanen et al, 1997) in strength over 4 ± 25 y. A reduction in type II muscle ®bers has been shown in some studies, but no change was found in others.…”

Sarcopenia and its implications for the elderly

Sarcopenia is the loss of muscle mass and strength with age. Sarcopenia is a part of normal aging, and occurs even in master athletes, although it is clearly accelerated by physical inactivity. Sarcopenia contributes to disability, reduced ability to cope with the stress of a major illness, and to mortality in the elderly. The etiology of sarcopenia is unclear, but several important factors have been identi®ed. These include loss of alpha motor neurons, decline in muscle cell contractility, and several potential humoral factors, such as androgen and estrogen withdrawal and increase in production of catabolic cytokines. Treatment of sarcopenia with progressive resistance training is safe and effective, but dissemination of this technique to the general population has yet to occur. As the number of elderly persons increases exponentially in the new century, a public health approach to prevention and treatment of sarcopenia, based on increasing physical activity at all ages, will be crucial to avoiding an epidemic of disability in the future.

Background: A recent meta-analysis found that cholecalciferol (vitamin D) should reduce falls by more than 20%. However, little is known about whether supplemental cholecalciferol plus calcium citrate malate will lower the long-term risk of falling in men, active older individuals, and older individuals with higher 25hydroxyvitamin D levels. Methods:We studied the effect of 3-year supplementation with cholecalciferol-calcium on the risk of falling at least once in 199 men and 246 women 65 years or older and living at home. Individuals received 700 IU of cholecalciferol plus 500 mg of calcium citrate malate per day or placebo in a randomized double-blind manner. Subjects were classified as less physically active if physical activity was below the median level. Low 25hydroxyvitamin D levels were classified as those below 32 ng/mL (Ͻ80 nmol/L).Results: In 3 years, 55% of women and 45% of men re-
