Rate Of Perceived Exertion And Cardiorespiratory Fitness In Older Adults With And Without Alzheimer's Disease, Andrea Bevan, Eric Dennis Vidoni, Amber Watts
International Journal of Exercise Science
International Journal of Exercise Science 13(3): 18-35, 2020. Exercise has many benefits for physical and cognitive health in older adults, yet there are many barriers to exercise adherence in this population. Subjective perception of exercise difficulty, or rate of perceived exertion (RPE), may especially be a barrier to exercise in individuals with Alzheimer’s disease (AD), due to changes in initiation and motivation that accompany changes in cognition and brain function. RPE is the most commonly used measure of subjective effort in exercise research, yet the relationship between RPE and objective fitness is not fully understood in older adults. A better …

International Journal of Exercise Science
International Journal of Exercise Science 13(1): 1-5, 2020. Statistical reporting of quantitative research data has been plagued by potential bias and reporting suppression due to a single numerical output: the p-value. While there is great importance in its merit, creating a pass-fail system (set at point of .05) has created a culture of researchers submitting their project’s data to a filing cabinet if it does not yield “statistical significance” based on this value. The editors of the International Journal of Exercise Science are following the American Statistical Association’s call for statistical reform by adjusting our reporting guidelines to the …

Acute Exercise On Memory Function: Open Vs. Closed Skilled Exercise, Justin Cantrelle, Grace Burnett, Paul D. Loprinzi
Faculty and Student Publications
© 2020 The Author(s). Background: Previous studies suggest that acute exercise may improve memory function. Few studies, however, have investigated the differential effect of the acute exercise movement patterns on memory. Such an effect is plausible, as research demonstrates that open-skilled exercise (e.g., racquetball) may have a greater effect on memory-related neurotrophins (e.g., brain-derived neurotrophic factors) when compared to closed-skilled exercise (e.g. treadmill exercise). A key distinction between open- and closed-skilled exercise is that open-skilled exercises are those that require an individual to react in a dynamic way to a changing, unpredictable environment. Our aim in this study was to …
