Beskrivelse
Inclusion Criteria:
- 55 years of age or older;
- Present with controlled or uncontrolled stage 1 hypertension (seated, resting clinic SBP 140 to 179 mmHg and/or DBP 90 to 109 mmHg) as per Hypertension Canada's 2017 Guidelines;
- Have preserved instrumental activities of daily living (scoring >6/8 on the Lawton-Brody Instrumental Activities of Daily Living [IADL] scale);
- Present signs of SCD (defined as answering yes to the question: "Do you feel like your memory or thinking skills have gotten worse recently?");
- Report being concerned about SCD (defined as answering yes to the question: "If yes, are you concerned about the worsening of your memory or thinking skills?");
- Preserved objective cognitive performance (i.e., no signs of MCI or dementia) defined by scoring ≥ 26 on the Montreal Cognitive Assessment (MoCA);
- Must be able to provide written informed consent.
Exclusion Criteria:
- Present signs of objective cognitive impairment (i.e., signs of MCI or dementia), defined by scoring ≤ 25 on the MoCA combined with study physician consult;
- Present resting stage 2 hypertension (seated, resting clinic SBP ≥ 180 mmHg and/or DBP ≥ 110 mmHg);
- Present significant neurological conditions or psychiatric disorders (e.g., Parkinson's disease or stroke <1 year); 4) present history of severe cardiovascular conditions (e.g., recent [<1 year] myocardial infarction, left ventricular hypertrophy) and symptomatic cerebrovascular disease;
- Present significant orthopaedic conditions (e.g., severe osteoarthritis in the lower limbs);
- Present untreated clinical depression (i.e., score >15 on the Center for Epidemiologic Studies - Depression scale combined with study physician consult);
- Unable to comprehend the study letter of information. Participants will also be excluded for any other factors that could potentially limit their ability to fully participate in the study.

Eksperimentel: High-intensity Interval Training (HIT)
Participants in this groups will receive 15 minutes in the mind-motor training (i.e., Square-Stepping Exercise) followed by a 45-minute HIT intervention.
|
Following the mind-motor training component, participants in the experimental group will then continue in the 45-minute HIT intervention, which will be composed by a 10-minute warm-up, a 25-minute core activity, and a 10-minute cool down.
The 25-minute core activity will be carried out based on a 4 x 4 minutes aerobic interval training model.
The intensity in each cycle will be prescribed at an individual level, and training heart rates will be determined via a sub-maximal excise testing at baseline and monitored during exercise using a wrist-based heart rate monitor (Suunto).
In order to ensure progression in aerobic training over the 6-month intervention, training heart rates will be recalculated at the intervention midpoint (i.e., 3 months), where a new sub-maximal exercise test will be performed.
Participants will exercise 60 minutes/day, 3 days/week for 6 months.

Aktiv komparator: Moderate-intensity Continuous Training (MCT)
Participants in this groups will receive 15 minutes in the mind-motor training (i.e., Square-Stepping Exercise) followed by a 45-min MCT intervention.
|
After the mind-motor training component, participants in the comparison/control group will then continue in the 45-min MCT intervention, which will be composed by a 10-minute warm-up a 25-minute moderate-intensity continuous aerobic exercise training, and a 10-minute cool down.
The exercise intensity will be prescribed at an individual level, and training heart rates will be determined via a sub-maximal excise testing at baseline and monitored during exercise using a wrist-based heart rate monitor (Suunto).
In order to ensure progression in aerobic training over the 6-month intervention, training heart rates will be recalculated at the intervention midpoint (i.e., 3 months), where a new sub-maximal exercise test will be performed.
Participants will exercise 60 minutes/day, 3 days/week for 6 months.

Memory
Tidsramme: 0 to 6 months
|
Composite measure derived from the Cambridge Brain Sciences cognitive battery (Hampshire, Highfield, Parkin, & Owen, 2012).
The composite score is derived from 4 cognitive tasks: Monkey Ladder (visuospatial working memory), Spatial Span (short-term memory), Digit Span (verbal working memory), and Paired Associates (visuospatial learning).
For each of the cognitive tasks, higher scores indicate better outcomes.
The scores from each task are standardized and averaged to generate a standardized composite measure of memory, i.e., z scores with a mean of 0 and a standard deviation of 1.
The standardized scores can range from negative infinity to positive infinity.

Reasoning
Tidsramme: 0 to 6 months
|
Composite measure from the Cambridge Brain Sciences cognitive battery.
The composite score is derived from 3 cognitive tasks: Grammatical Reasoning (verbal reasoning), Double Trouble (modified Stroop task), and Odd One Out (deductive reasoning).
For each of the cognitive tasks, higher scores indicate better outcomes.
The scores from each task are standardized and averaged to generate a standardized composite measure of reasoning, i.e., z scores with a mean of 0 and a standard deviation of 1.
The standardized scores can range from negative infinity to positive infinity.

Planning

Composite measure from the Cambridge Brain Sciences cognitive battery.
The composite score is derived from 2 cognitive tasks: Spatial Planning (planning and executive function) and Token Search (working memory and strategy).
For each of the cognitive tasks, higher scores indicate better outcomes.
The scores from each task are standardized and averaged to generate a standardized composite measure, i.e., z scores with a mean of 0 and a standard deviation of 1.
The standardized scores can range from negative infinity to positive infinity.

Composite measure from the Cambridge Brain Sciences cognitive battery.
The composite score is derived from 3 cognitive tasks: Rotations (mental rotation), Feature Match (feature-based attention and concentration), and Polygons (visuospatial processing).
For each of the cognitive tasks, higher scores indicate better outcomes.
The scores from each task are standardized and averaged to generate a standardized composite measure, i.e., z scores with a mean of 0 and a standard deviation of 1.

Dual-Task Gait Velocity
Tidsramme: 0 to 6 months
|
Dual-task velocity is measured in centimetres/second and will be assessed via an electronic walkway (GAITRite® System, 420 cm long, 90 cm wide; CIR Systems).
Participants will complete: 1) a single-task walking trial at their own pace; followed by two dual-task walking trials: 2a) walking while naming animals (at baseline) or vegetables (at study endpoint) and 2b) walking while subtracting serial sevens from 90 (at baseline) or 80 (at study endpoint).
