Intervention / Treatment
Detailed Description
The current randomized clinical trial is designed to examine (1) whether a 6-month integrated intervention program (IIP) consisting of multiple exercise modalities, meditation, and social interaction could benefit neurocognitive function (e.g., inhibition) in middle-aged and older adults; (2) whether components of ERP will be influenced by the integrated intervention program; and (3) whether apolipoprotein E (ApoE) genotypes (ApoE e3/e4, ApoE e4/e4, ApoE e2/e2, ApoE e2/e3, ApoE e2/e4, and ApoE e3/e3), physical fitness, and brain-derived neurotrophic factor (BDNF) will influence the effects of an integrated intervention program on neurocognitive function and components of ERPs.
The study will randomly assign 100 eligible participants to either the IIP group or the control group in a 1:1 ratio. The IIP group will engage in 150 min of exercise per week, which consists of one 90-min on-site session and multiple online sessions, for 6 months. The control group will be invited to attend one 60-minutes online educational course per week for 6 months.
The neurocognitive function, the components of ERP, ApoE genotype, physical fitness, and BDNF will be assessed at the baseline (Baseline-Assessment) and the end of the 6-month intervention (Post-Assessment).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Integrated Intervention Group (IIG)
The IIG attends 150 min exercise per week, which consists of one 90-min trainer-supervised program and multiple online sessions, for 6 months. Intervention: aerobic exercise, resistance exercise, coordinative exercise, flexibility, social interaction, and meditation. |
The IIG attends 150 min exercise per week, which consists of one 90-min trainer-supervised session and multiple online sessions for 6 months.
Each session consists of (1) warm-up, (2) resistance exercise and flexibility exercise, (3) resistance exercise and coordinative exercise from the "Eastern exercise" perspective, (4) social interaction exercise, and (5) cool-down and meditation.
|
Other: Control Group
The control group is invited to attend one 60-min online educational course per week for 6 months. Intervention: 60-min online educational program. |
The Control Group is informed to maintain their lifestyles and invited to attend one 60-min online educational course per week.
The participants are required to provide their physical activity behavior once every month for 6 months (6 times).

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Inhibition: Changes in Stroop test performance
Time Frame: 30 minutes each at the baseline and at month 6
|
The computerized Stroop test is administrated to assess participants' inhibitory function, and the changes in Stroop test performance from baseline to end of the intervention (i.e., month 6) will be examined.
|
30 minutes each at the baseline and at month 6
|
Changes in neuroelectrical activities
Time Frame: 60 minutes each at baseline and at month 6
|
The neuroelectrical activities during the computerized cognitive tasks is recorded and analyzed using the Neuroscan system.
Changes in the neuroelectrical activities from baseline to end of the intervention (i.e., month 6) will be examined.
|
60 minutes each at baseline and at month 6
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
ApoE genotype
Time Frame: 5 minutes at baseline
|
A 6 mL serum sample is drawn from the antecubital veins.
Based on the genetic biomarkers (rs429358 and rs7412), participants' ApoE genotype is determined at the baseline.
|
5 minutes at baseline
|
Blood neurotrophic marker: Changes in brain-derived neurotrophic factor (BDNF) levels
Time Frame: 5 minutes each at baseline and at month 6
|
A 6 mL serum sample is drawn from the antecubital veins to assess BDNF levels, and changes in BDNF levels from baseline to end of intervention (i.e., month 6) will be examined.
|
5 minutes each at baseline and at month 6
|
Physical fitness measurements: Changes in aerobic fitness
Time Frame: 30 minutes each at baseline and at month 6
|
Participants' aerobic fitness is assessed using the submaximal cycle ergometer test, and changes in aerobic fitness from baseline to end of intervention (i.e., month 6) will be examined.
|

|
Geriatric Depression Scale (GDS-15) is utilized to assess older adults' depression levels using 15 'Yes/No' items.
Scores between 5 and 9 indicate mild symptoms, and a score of 10 and above indicates moderate symptoms.
Changes in depression from baseline to end of intervention (i.e., month 6) will be examined.

|
Psychosocial measures: Changes in sleeping quality
Time Frame: 5 minutes each at baseline and at month 6
|
The Chinese version of the Pittsburgh Sleep Quality Index will be used to assess individual's general sleep quality over a 1-month time interval.
Participants complete 9 questions, and lower scores reflect better sleep quality.
