This exploratory study described the experiences of choice in physical activity contexts for adults with mobility impairments. The experiences of 3 female and 2 males with mobility impairments between 18 and 23 years of age were described using the interpretive phenomenological methods of individual interviews, written stories, and field notes. Thematic analysis revealed three themes: (a) interpreting the setting described participants’ interpretation of the environment, person, and task when making movement choices; (b) alternative selection described how participants actively engaged in analyzing alternatives and choosing among them; and (c) implications of choices made described participants’ evaluations of good and bad choices and what was learned. Evidence of effective choice making among adults with physical impairments suggests the potential efficacy of ecological task analysis as a pedagogical tool in physical activity contexts.

Stretching prior to activity or as a rehabilitative intervention may promote increased throwing shoulder range of motion (ROM) in baseball pitchers.
To evaluate the acute effects of Fauls modified passive stretching routine on throwing shoulder mobility in collegiate baseball players.
Thirty collegiate baseball players with unimpaired shoulders.
Fauls modified passive stretching routine was performed on the throwing shoulder of each subject.
Shoulder complex and passive isolated glenohumeral internal and external rotation ROM were measured with a goniometer, and posterior shoulder tightness was assessed with the Tyler’s test method using a carpenter’s square. Measurements were made bilaterally.
The dominant shoulder displayed significant increases in glenohumeral and shoulder complex internal and external rotation ROM and significantly decreased posterior shoulder tightness following the stretching routine.
Application of the Fauls modified passive shoulder stretching routine results in acute gains in throwing shoulder mobility of collegiate baseball players.

This study descriptively measured the universal accessibility of “accessible” fitness and recreational facilities for Ontarians living with mobility disabilities. The physical and social environments of 44 fitness and recreational facilities that identified as “accessible” were assessed using a modified version of the AIMFREE. None of the 44 facilities were completely accessible. Mean accessibility ratings ranged between 31 and 63 out of a possible 100. Overall, recreational facilities had higher accessibility scores than fitness centers, with significant differences found on professional support and training, entrance areas, and parking lot. A modest correlation was found between the availability of fitness programming and the overall accessibility of fitness-center specific facility areas. Overall, the physical and social environments of the 44 fitness and recreational facilities assessed were limited in their accessibility for persons with mobility disabilities. Future efforts should be directed at establishing and meeting universal accessibility guidelines for Canadian physical activity facilities.

An arm ergometer analog of the Canadian Aerobic Fitness Test (CAFT) has been proposed for subjects with impairments of mobility (Longmuir & Shephard, 1995). Because of muscle weakness or spasm, only 63% of the adults concerned could maintain the required cadence in the original test version. Thus, in the present study it was hypothesized that a reduced crank loading would yield a higher success rate. In a sample of 35 adults with mobility impairment, 82% were able to complete at least one stage of the modified test. Difficulty was encountered mainly by persons with cerebral palsy or multiple sclerosis. The revised protocol had a high (r = .97) 1-week test/retest reliability, with no test/retest bias except that subjects with brain lesions scored somewhat higher at their second assessment. A scaled prediction of peak oxygen intake using the standard CAFT equation agreed closely with direct arm ergometer determinations of it. The modified test showed a mean discrepancy ±SD of 0.1 ± 4.8 ml/[kg · min]. Further validation is needed, but the current analog of the standard CAFT appears to be useful for many with mobility impairments.

This study investigated associations between variables of trunk muscle strength (TMS), spinal mobility, and balance in seniors. Thirty-four seniors (sex: 18 female, 16 male; age: 70 ± 4 years; activity level: 13 ± 7 hr/week) were tested for maximal isometric strength (MIS) of the trunk extensors, flexors, lateral flexors, rotators, spinal mobility, and steady-state, reactive, and proactive balance. Significant correlations were detected between all measures of TMS and static steady-state balance (r = .43−.57, p < .05). Significant correlations were observed between specific measures of TMS and dynamic steady-state balance (r = .42−.55, p < .05). No significant correlations were found between all variables of TMS and reactive/proactive balance and between all variables of spinal mobility and balance. Regression analyses revealed that TMS explains between 1–33% of total variance of the respective balance parameters. Findings indicate that TMS is related to measures of steady-state balance which may imply that TMS promoting exercises should be integrated in strength training for seniors.

This study was designed to investigate the effects of vibration on muscle performance and mobility in a healthy, untrained, older population. Forty-three participants (23 men, 20 women, 66–85 y old) performed tests of sit-to-stand (STS), 5- and 10-m fast walk, timed up-and-go test, stair mobility, and strength. Participants were randomly assigned to a vibration group, an exercise-without-vibration group, or a control group. Training consisted of 3 sessions/wk for 2 mo. After training, the vibration and exercise groups showed improved STS (12.4%, 10.2%), 5-m fast walk (3.0%, 3.7%), and knee-extension strength (8.1%, 7.2%) compared with the control (p < 0.05). Even though vibration training improved lower limb strength, it did not appear to have a facilitatory effect on functional-performance tasks compared with the exercise-without-vibration group. Comparable mobility and performance changes between the experimental groups suggest that improvements are linked with greater knee-extension strength and largely attributed to the unloaded squats performed by both exercise groups.

Individuals with severe physical and psychomotor modifications after a brain injury need measures of motor training beyond the usual physiotherapy. The effects of an intensive mobility training in the phase of late rehabilitation are reported in two case studies. The coordinative and conditional progresses were controlled by the methods of photographic anthropometry, light-track registration, and bicycle ergometry. Improvements were found in posture and dynamic endurance in correlation with the generally improving motor control. Tests of everyday relevant movements revealed qualitative progresses in the sense of increased motor precision and economy.

The exact relation between objectively measured moderate-to-vigorous physical activity (MVPA) and independent mobility in children has yet to be fully defined. The objective of this study was to determine whether independent mobility is associated with level of MVPA.
Data were collected from 9 middle schools in Porto (Portugal) area. A total of 636 children in the 6th grade (340 girls and 296 boys) with a mean age of 11.64 years old participated in the study. PA was measured in 636 participants using an accelerometer. Multinomial logistic regression was applied to assess the odds for belonging to quartiles of MVPA.
After controlling for age, gender, body mass index, meeting PA recommendations, and participation in structured exercise, the odds of having a higher level of MVPA when children have higher independent mobility increase through the MVPA quartiles.
A positive associations were found between independent mobility and quartiles of physical activity.

Our aim was to study the effects of sense of coherence (SOC) on training adherence and interindividual changes in muscle strength, mobility, and balance after resistance training in older people with hip fracture history. These are secondary analyses of a 12-week randomized controlled trial of progressive resistance training in 60- to 85-year-old community-dwelling people 0.5–7 years after hip fracture (n = 45; ISRCTN34271567). Pre- and posttrial assessments included SOC, knee extension strength, walking speed, timed up-and-go (TUG), and Berg Balance Scale (BBS). Group-by-SOC interaction effects (repeated-measures ANOVA) were statistically significant for TUG (p = .005) and BBS (p = .040), but not for knee extension strength or walking speed. Weaker SOC was associated with poorer training adherence (mixed model; p = .009). Thus, more complicated physical tasks did not improve in those with weaker SOC, independently of training adherence. Older people with weaker SOC may need additional psychosocial support in physical rehabilitation programs to optimize training response.

To characterize patterns of sedentary behavior and physical activity in older adults recovering from hip fracture and to determine characteristics associated with activity.
Community-dwelling, Canadian adults (65 years+) who sustained hip fracture wore an accelerometer at the waist for seven days and provided information on quality of life, falls self-efficacy, cognitive functioning, and mobility.
There were 53 older adults (mean age [SD] 79.5 [7.8] years) enrolled in the study; 49 had valid data and demonstrated high levels of sedentary time (median [p10, p90] 591.3 [482.2, 707.2] minutes/day), low levels of light activity (186.6 [72.6, 293.7]), and MVPA (2 [0.1, 27.6]), as well as few daily steps (2467.7 [617.1, 6820.4]). Regression analyses showed that age, gender, gait speed, and time since fracture were associated with outcomes.
Older adults have long periods of sedentary time with minimal activity. Results are a call to action to encourage people to sit less and move more.
