Of direct relevance to the current study, Norman, Hart, and Petherick ( 2019 ) note that “displacing, spatially confining, and restricting mobilities are pivotal strategies by which European settlers have dispossessed Indigenous

The purpose of this study was to determine whether a walking program supplemented by tasks designed to challenge balance and mobility (WALK+) could improve physical function more than a traditional walking program (WALK) in older adults at risk for mobility disability. 31 community-dwelling older adults (M ± SD age = 76 ± 5 yr; Short Physical Performance Battery [SPPB] score = 8.4 ± 1.7) were randomized to treatment. Both interventions were 18 sessions (1 hr, 3×/wk) and progressive in intensity and duration. Physical function was assessed using the SPPB and the 400-m-walk time. A subset of participants in the WALK group who had relatively lower baseline function showed only small improvement in their SPPB scores after the intervention (0.3 ± 0.5), whereas a subset of participants in the WALK+ group with low baseline function showed substantial improvement in their SPPB scores (2.2 ± 0.7). These preliminary data underscore the potential importance of tailoring interventions for older adults based on baseline levels of physical function.

The purpose of this study was to pilot test a function-focused exercise intervention consisting of strength and gait-speed training in elders with reduced walking speed, decreased walking endurance, and functional impairment. Twelve participants, 77.2 years old (± 7.34), whose usual gait speed was <0.85 m/s, with walking endurance of <305 m in 5 min, and who were functionally impaired participated in a moderate-intensity exercise intervention. The training occurred 3 times per week, 75 min per session, for 3 months and combined 4 weeks of gait-speed training, walking exercise, and functional strengthening. The participants demonstrated mean usual gait speeds (≥1.0 m/s), endurance (≥350 m), and functional ability (≥10 score on performance battery) that were within normal limits after 12 weeks of training. Fastest gait speed (≥1.5 m/s) and muscle strength also improved significantly. Improvements were maintained during follow-up testing after 3–6 months. In summary, a 12-week intervention for frail, mobility-disabled participants led to improvements in walking, function, and strength.

The purpose of this study was to investigate what older adults with severe, moderate, or no mobility limitation consider motives for and barriers to engaging in physical exercise. Community-dwelling adults (N = 645) age 75–81 years completed a questionnaire about their motives for and barriers to physical exercise and answered interview questions on mobility limitation. Those with severely limited mobility more often reported poor health, fear and negative experiences, lack of company, and an unsuitable environment as barriers to exercise than did those with no mobility limitation. They also accentuated disease management as a motive for exercise, whereas those with no or moderate mobility limitation emphasized health promotion and positive experiences related to exercise. Information about differences in motives for and barriers to exercise among people with and without mobility limitation helps tailor support systems that support engagement in physical activity among older adults.

This secondary analysis of data drawn from a descriptive phenomenological study explored how older adults with low vision experience and manage community mobility. Participants included 34 urban and rural older adults, age 70 years and older, who were not using low-vision-rehabilitation services. The findings convey a core element of the experience of community mobility for participants: living with a pervasive sense of fear regarding one’s body and way of being. Participants continually gauged risks associated with mobility and engaged in risk avoidance and management strategies. Community mobility was often restricted by participants because of perceived risks, leading to reduced participation in a range of physical, social, and other types of activities. Further research on environmental factors mediating community mobility and on strategies effective in maintaining mobility among seniors with low vision is essential to optimize participation, health, and service delivery.

The aging process is characterized by reductions in dynamic and postural balance, muscle mass, and mobility ( Janssen, Heymsfield, & Ross, 2002 ). The histological features of aging muscle suggest that denervation contributes to muscle atrophy ( Mosole et al., 2014 ) and muscle weakness ( Joyner

Relationships between context-specific measures of the physical and social environment and children’s independent mobility to neighborhood destination types were examined.
Parents in RESIDE’s fourth survey reported whether their child (8–15 years; n = 181) was allowed to travel without an adult to school, friend’s house, park and local shop. Objective physical environment measures were matched to each of these destinations. Social environment measures included neighborhood perceptions and items specific to local independent mobility.
Independent mobility to local destinations ranged from 30% to 48%. Independent mobility to a local park was less likely as the distance to the closest park (small and large size) increased and less likely with additional school grounds (P < .05). Independent mobility to school was less likely as the distance to the closest large park increased and if the neighborhood was perceived as unsafe (P < .05). Independent mobility to a park or shops decreased if parenting social norms were unsupportive of children’s local independent movement (P < .05).
Independent mobility appears dependent upon the specific destination being visited and the impact of neighborhood features varies according to the destination examined. Findings highlight the importance of access to different types and sizes of urban green space for children’s independent mobility to parks.

The purpose of this study was to evaluate the differences in body composition, neuromuscular performance, and mobility in healthy, regularly exercising and inactive older women, and examine the relationship between skeletal muscle indices and mobility. Overall, 32 healthy older women participated. They were divided into groups according to their physical activity history as regularly exercising (n = 22) and inactive (n = 10) women. Body composition, hand grip strength, leg extensor muscle strength, rapid force development, power output, and mobility indices were assessed. Regularly exercising women had lower fat mass and higher values for leg extensor muscle strength and muscle quality, and also for mobility. Leg extensor muscle strength and power output during vertical jumping and appendicular lean mass per unit of body mass were associated with mobility in healthy older women. It was concluded that long-term regular exercising may have beneficial effects on body composition and physical function in older women.
