Physical fitness and executive decision-making in people at risk for Alzheimer's
Physical Fitness and Hot Executive Function in Alzheimer's Risk
National Taiwan Normal University · NCT07081269
Over 18 months, this project will see if changes in cardiorespiratory and muscle fitness predict changes in executive thinking and EEG brain signals in adults aged 50–70 who are at risk for Alzheimer's.

What this trial studies
This prospective observational study follows adults aged 50–70 for 18 months to examine links between health-related physical fitness and both behavioral and electrophysiological measures of executive function. Participants complete baseline and 18-month visits that include YMCA submaximal cycle ergometry for cardiorespiratory fitness, one-repetition maximum chest and leg press for muscular strength, and computerized task-switching paradigms with simultaneous EEG recording. Secondary measures include the MMSE, digit span, physical activity questionnaires, demographics, and APOE ε4 genotyping to explore moderation effects. No exercise program is provided, so the study captures natural changes in fitness and cognition in daily life.
Who should consider this trial
Good fit: Adults aged 50–70 who can safely complete submaximal and strength fitness testing, have normal or corrected vision, and do not have major cardiopulmonary, neurological, psychiatric, or infectious illnesses.
Not a fit: People with dementia or other major neurological/psychiatric disorders, cardiopulmonary disease, active infections, medications that affect brain function, or color-vision deficiency are excluded and would not be expected to benefit from participation.
Why it matters
Potential benefit: If successful, the findings could identify fitness markers that predict cognitive decline and help guide early lifestyle strategies to preserve thinking skills.
How similar studies have performed: Previous observational work has linked higher cardiorespiratory fitness to better executive function and EEG markers, though causal evidence is limited and this study builds on those associations.
