The aim of this study was to identify determinants of walking and whether walking maintained mobility among women as they transition from their mid-70s to their late 80s. We used 12 years of follow-up data (baseline 1999) from the Australian Longitudinal Study on Women’s Health (n = 10,322). Fifteen determinants of walking were included in the analysis and three indicators of mobility. Longitudinal data analyses techniques were employed. Thirteen of the 15 determinants were significant predictors of walking. Women in their mid-70s who walked up to 1 hr per week were less likely to experience loss of mobility in very old age, including reduced likelihood of using a mobility aid. Hence, older women who do no walking should be encouraged to walk to maintain their mobility and their independence as they age, particularly women in their 70s and 80s who smoke, are overweight, have arthritis, or who have had a recent fall.

Age-related sarcopenia and osteoporosis-related fractures are critical health issues among older adults. In general, many older adults suffer from fractures and spend much time in bed rest, inducing decreased skeletal muscle mass and function deterioration, such as in activities of daily living

Older adults experience age-related declines in skeletal muscle strength and functional capacity ( Baker et al., 2020 ). Neural and morphological factors, as well as their interaction, are responsible for age-related declines ( Aagaard, Suetta, Caserotti, Magnusson, & Kjær, 2010 ). In addition

). This survey reported that four in ten (38%) of Aboriginal and Torres Strait Islander adults from nonremote areas were sufficiently active for optimum health ( Australian Bureau of Statistics, 2013 ). However, this declined in older adults surveyed, with only 18.5% of adults aged 45–54 years and 16

In response to the aging global population, the World Health Organization (WHO) is developing a Global Strategy and Action Plan on Aging and Health ( World Health Organization, 2015 ). Healthy aging has recently been re-framed to emphasize the capacity of individuals and the interactions between

( Clemencon et al., 2008 ; Cuoco et al., 2004 ). Furthermore, due to the accentuated decline of muscle power among older females as compared with males, there is an urgent need to develop strategies to counteract age-related losses in muscle power in this population. One particular strategy used to offset

Fifteen community dwelling older adults, ages 66 to 97 years, with at least one risk factor for recurrent falls, attended a thrice weekly group exercise class for 8 weeks. In post- versus preexercise comparisons, knee extensor torque at 0°/sec increased by 16.5% (p = 0.055); time to perform the stand-up test once, and five times consecutively, improved by 29.4 and 27.4%, respectively (p = 0.05, p = 0.01); gait speed for 24 feet increased by 16.5% (p < 0.001); and performance of the progressive Romberg test of balance improved with a mean increase of 1.1 ± 0.9 positions (p = 0.001). Participants reported a significant increase in the mean number of times per week that they went out of their apartment/home independent of exercising, and a significant increase in the mean number of city blocks they could walk. Performance data for nine exercise participants at 1-yr postintervention are presented. A low- to moderate-intensity groups exercise program can effect improvements in lower extremity strength, gait speed, balance, and self-reported mobility function in frail older adults.

Advances in the knowledge of acromegaly are leading to an increase in the survival rate of acromegalic subjects. This study was conducted to evaluate balance control, risk of falls, and peripheral muscle function in acromegalic older adults. Seventeen older subjects with acromegaly (67 [63–73] years) and 20 paired control subjects were evaluated with balance scales, force platform, and knee isokinetic dynamometry tests. There were significant differences between the groups on several balance and gait scales, with a worse performance and greater risk of falls in the acromegalic older adults. Acromegalic older adults had lower values for peak torque, maximum repetition of the total work, and total work during extension at 240°/s. The acromegalic older adults had higher values in the medial-lateral range. Acromegaly subjects had lateral instability that compromises their body balance and increases the risk of falls. Moreover, there was a propensity for muscle fatigue in these individuals.

During the 20th century, approximately 30 years were added to human life expectancy ( Oeppen & Vaupel, 2002 ). This increase in life expectancy, coupled with better health care and declining fertility rates, has led to a significant aging of the global population. Consequently, the number of people

The objective of this study was to determine whether improved balance outcomes achieved in a randomized controlled trial (RCT) using balance screening to identify mild balance dysfunction and home exercises could be translated into community settings. Community-dwelling people aged over 65 who expressed concerns about their balance, had less than two falls in the preceding 12 months, and who had mild balance impairment on screening were given an individualized home-based balance and strengthening exercise program with intermittent home-visit support by a physiotherapist. Of 71 participants assessed (mean age 77.3 years, 76% female), 58 (82%) completed the six-month intervention. Twenty six percent of participants regained balance performance within normal limits—similar to those achieved in the previous RCT. Successful results from a previous RCT were able to be translated into community settings, with a similar magnitude of effect on balance and mobility.
