The effects of exercise on cognitive functioning For your discussion question, you will identify two peer-reviewed articles that could be used for your pre-proposal assignment. These articles should be different from the ones you found for the first week. Please read The Pre-Proposal Scoring Guide and review The Pre-Proposal Annotated Template in Unit 9 for more information. Key parts of empirical articles include an overview of the approach used, the research design, purpose, sampling method, research questions or hypotheses, instrumentation, cultural considerations, data analysis procedures, and general findings. Prepare an annotated summary for each study, summarizing the material in your own words, not direct quotes. Your annotation should briefly cover these elements: the research approach (qualitative or quantitative), the research design, purpose, sampling method, research question/hypothesis, instrumentation, cultural issues, data analysis method, and main findings. The length of each annotation should be approximately 200–250 words, totaling 400–500 words for both. Focus on studies examining the effects of exercise on cognitive functioning to support your pre-proposal research on this topic.
Paper For Above instruction In this discussion, two peer-reviewed empirical studies examining the effects of exercise on cognitive functioning are summarized to support a comprehensive understanding of existing research and inform a future research proposal. These summaries highlight key aspects of each study, including research approach, methodology, purpose, sampling, data analysis, and findings, providing an organized foundation for a high-quality literature review. Study One: Impact of Aerobic Exercise on Cognitive Function in Older Adults This study adopts a quantitative approach, utilizing a randomized controlled trial (RCT) design to assess the effects of aerobic exercise on cognitive performance in older adults. The primary purpose was to determine whether regular aerobic activity led to measurable improvements in cognitive domains such as memory, executive function, and attention. Participants were community-dwelling adults aged 65–80 recruited via advertisements and screened for health conditions that might affect participation. The sample was randomly assigned into an exercise group, engaging in supervised aerobic activities three times per week, and a control group, maintaining their usual activities without intervention. The researchers hypothesized that the exercise group would demonstrate significant cognitive enhancements compared to controls. Instruments included standardized neuropsychological tests, such as the Stroop test and digit span
