- ItemOpen AccessImpact of Interactive Stationary Exercise Cycling on Cognitive Attention Among Adults(2015-11-18) Donaldson, Gerald Douglas; Katz, LarryBackground: There is little research reporting whether navigating while cycling impacts concurrent cognitive tasks that are negligibly related to navigation tasks. Methods/Design: A 3-way ANOVA with two repeated measures (3 x 2 x 2) was used to compare 48 adults, aged 18-71, on memory recall of sequences of 42 monosyllabic words while At-Rest and while Riding an interactive stationary exercise cycle, in the presence and absence of an arithmetic distraction, across three groups of navigation: Gauges (n=17), Touring (n=17) and Gaming (n=14). Results: Sequential word recall varied with Touring and Gaming but not Gauge Monitoring, for resting and riding where distraction was present as well as where distraction was absent. The difference between the presence and absence of a distraction was also significant. Conclusion: Cognitive performance was negatively impacted by virtual navigation tasks when riding a stationary cycle, the more so when an arithmetic distraction was present.
- ItemOpen AccessUnderstanding Engagement in Physical Activity Over the Life Course to Promote Healthy Aging(2022-08-29) Donaldson, Gerald Douglas; Katz, Larry; Werthner, Penny Christine; Boyd, Jeffrey Edwin; Sheehan, Dwayne PThe analyses presented in this dissertation reconceptualized the philosophical speculations that underpinned the epistemological foundations of Margaret Whitehead’s Physical Literacy paradigm with attention to scientific claims of evidence. Establishing a scientific foundation for physical literacy as a holistic, immersive paradigm led to the notion that interactive experiences are laboratory exemplars for testing the motivation of Physical Literacy’s holistic experiences. This led to a randomized, comparative trial (RCT) of two cycling interfaces - 2D monitor and 360° headset – that demonstrated, for both conditions, motivation to engage in physical activity while exergaming increased equally. Experiences associated with 2D monitors and 360° VR headsets with interactive cycling and gaming illustrated a safe and enjoyable way to engage seniors in mitigating sedentary behavior while actively engaging in physical activity. This has important implications for the design and development of exergaming systems. The results of the RCT study found that interactive exergaming while cycling with immersive interfaces led to increased enjoyment, was encouraging, and gave rise to an exploration that has potential to foster lifelong engagement in physical activity. A Delphi Method enabled experts to generate and discuss recommendations for healthier lifespans by managing physical and sedentary behaviors across the lifespan.
