Abstract Objectives To examine the relationship between Facebook (FB) use, relatedness and exercise motivation. Design Two studies comprised a mixed-methods concurrent design. Study 1 was a cross-sectional quantitative assessment of the relationships between FB use, relatedness and exercise motivation. Study 2 explored qualitative perceptions of how FB influences exercise motivation. Method Study 1: 311 undergraduate students completed a survey assessing FB use, exercise motivation and relatedness. Mediation analysis was conducted to examine relationships. Study 2: 19 participants took part in focus groups exploring experiences of exercise-related FB use and its perceived role in motivation. Results Study 1: FB use was related to external and introjected regulation. Relatedness mediated the relationships between FB use, introjection, and autonomous forms of motivation. Study 2: Qualitative data suggested FB can either promote (through connection, positive social comparison) or discourage exercise (through disconnection, negative social comparison, health-negating features). Conclusion FB use was related to external and introjected regulation. Positive relationships between FB and autonomous forms of motivation were mediated by relatedness, suggesting that interventions should focus on fostering feelings of connection with others. FB use that encourages relatedness with like-minded individuals has potential to promote autonomous motivation for exercise. Highlights • FB can influence both controlled and autonomous forms of motivation. • Relatedness mediates the relationship between FB use and exercise motivation. • FB use that leads to feelings of disconnection can have negative effects on exercise.

Background: Walking is a cognition intensive activity and impaired walking is associated with an increased fall risk in people with Alzheimer's dementia (AD). Walking in a curved path configuration increases complexity of the task, reflects real-life environments and situations when falls occur. The effect of walking path task complexity has not been evaluated in people with AD.Research Question: The purpose was 1) to assess the utility of a curved path walking task to detect differences in gait performance between people with AD and healthy controls and 2) to assess the relationship of cognitive function to gait performance on straight path and curved path walking.Methods: Participants with AD (n = 14, mean age ± SD = 73.08 ± 9.22) and age and sex matched controls (n = 14, mean age = 72.86 ± 9.53) were recruited. Time to complete a 6-meter straight path and a curved path (Figure of 8 Test) walking task was recorded. Steps taken, accuracy and qualitative measures of smoothness were rated for curved-path walking. Measures of global cognition (MMSE, MoCA) and executive function (Trail making A and B, Digit Span forwards and backwards) were assessed.Results: Gait was significantly slower in people with AD for both the straight-path (AD = 6.05 ± 1.26 s, Control = 5.09 ± 0.76 s, p = 0.02) and curved-path walking (AD = 11.25 ± 4.87 s, Control = 8.28 ± 2.44 s, p = 0.05). In addition, smoothness scores were significantly lower for people with AD (AD = 1.93±1.26; Control = 3.00±0.00, p = 0.004).Significance: Walking in a curved path resulted in a significant deterioration in gait quality in the people with AD. Executive function was related only to curved path walking, in which lower executive function scores were associated with longer time to walk. [ABSTRACT FROM AUTHOR]- Published

• Walking with a 4-wheeled walker is a complex motor task. • People with Alzheimer's dementia experienced using a 4-wheeled walker were tested. • Complex walking paths and cognitive challenge resulted in increased instability. • People self-prioritized gait over the cognitive task in the most complex tests. Learning to walk with a 4-wheeled walker increases cognitive demands in people with Alzheimer's dementia (AD). However, it is expected that experience will offset the increased cognitive demand. Current research has not yet evaluated gait in people with AD experienced in using a 4-wheeled walker under complex gait situations. What is the effect of dual-task testing on the spatial-temporal gait parameters and cognitive performance of people with AD experienced with a 4-wheeled walker? Twenty-three adults with mild to moderate AD (87.4 ± 6.2 years, 48 % female) and at least 6 months of walker use experience participated. Three walking configurations: 1) straight path (SP), 2) Groningen Meander Walking Test (GMWT), and 3) Figure of 8 path (F8) were tested under two walking conditions: 1) single-task (walking with aid) and 2) dual-task (walking with aid and completing a cognitive task). Tri-axial accelerometers collected velocity, cadence and stride time variability (STV). Gait and cognitive task cost were the percentage difference between single-task and dual-task conditions. Two-way repeated measures ANOVAs were used to answer the study question. A significant interaction between walking configuration and condition was found for velocity (p = 0.002, ω2 = 0.36), cadence (p = 0.04, ω2 = 0.15) and STV (p < 0.001, ω2 = 0.53). Velocity and cadence decreased and STV increased with increasing walking configuration complexity and upon dual-tasking. Dual-task gait and cognitive task cost deteriorated in all walking configurations, but gait was prioritized in the GMWT and F8 configurations. Despite familiarity, experienced walker users with AD exhibit impaired gait when walking in complex situations which increases falls risk. Upon dual-task, individuals with AD self-prioritized a posture-first strategy in complex configurations. Dual-task testing in experienced users results in slower walking, fewer steps and increased STV, which increases falls risk in people with mild to moderate AD and becomes most pronounced in complex environments.
