Exercise to Improve the Hearts and Minds of Canadian Older Adults With Hypertension: The Heart & Mind Study
Older adults with subjective cognitive decline (SCD) may represent a portion of the population experiencing early sings of cognitive decline.
Systolic hypertension is a major contributor to cognitive impairment.
High-intensity aerobic interval training (HIT) yields greater fitness and vascular health improvements compared to moderate-intensity aerobic continuous training (MCT).
No randomized controlled trials, however, have investigated the effects HIT or MCT on cognition in older adults with hypertension and SCD.
Much less is known regarding whether combining HIT or MCT with mind-motor training would culminate additive benefits to cognition.
Therefore, the overarching goal of our research is to deliver a group-based exercise program combining mind-motor training with HIT or MCT to older adults with hypertension and SCD.
Participants will be randomized into two groups.
Participants in both groups will receive 15 minutes of square stepping exercise (SSE) followed by either 45 minutes of HIT (N=70) or 45 minutes of MCT (N=70).
In total, both groups will exercise 60 min/day, 3 days/week for 6 months.
The effects of both interventions will be evaluated on systolic and diastolic office/ambulatory blood pressure and global and domain-specific cognitive functioning.

実験的：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.

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).

Memory
時間枠：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.
