Summary

The ACTIONcardioRisk trial is designed to investigate the effect of aerobic and progressive resistance training exercises combined with cognitive training, on neurocognitive functioning of sedentary older adults with and without cardiovascular risk factors.

Detailed description

The proportion of older adults is on the rise in Canada, with the fastest growth recorded among those seventy years of age or older. The prevalence of cardiovascular risk factors (CVRF) such as diabetes, hypertension, and high cholesterol increases drastically with age. Individuals with CVRF often show impaired cognition, such as attention and memory deficits. In healthy older adults, exercise training and cognitive stimulation can help enhance cognitive performances. More precisely, combined intervention, including physical and cognitive training, has shown beneficial effects on cognition in older adults without cognitive impairment and with mild cognitive impairment. However, the effect of such programs on cognition in individuals with CVRF is not well documented. This project compares the effect of a physical exercise program, including aerobic and resistance training, alone or combined with cognitive training on cognitive performances and brain imaging outcomes in individuals with CVRF and healthy controls.

Interventions

Type	Name	Description
OTHER	Cognitive Training	Participants will be encouraged to perform sessions of cognitive training 3 times per week (30 minutes/session). Two of these sessions will involve computer- or tablet-based attentional control training targeting dual-tasking, updating and working memory, as well as inhibition and switching. Difficulty of cognitive training will be tailored to participants' performances. The remaining session will consist of memory training. Participants will be instructed mnemotechnic, as well as be taught about memory in aging in general.
OTHER	Aerobic and resistance exercises	Participants will follow a periodized exercise training program with thrice-weekly 60 minutes trainings. The sessions will start with a 5-10mins warm-up, followed by aerobic and resistance trainings, and ends with a 5-10mins cool-down and stretching period. Intensity of aerobic sessions will be monitored with heart rate chest strap and should match with the moderate to vigorous intensity zone as defined by the ACSM (65% of Heart Rate maximum or more and a Perceived Exertion higher than 12 on the 6 to 20 Borg scale). Exercise intensity and duration will be gradually increased during the program. After aerobic training, a 15-20mins resistance training will be performed with a gradual progression of higher intensities and/or numbers of sets. The one maximal repetition (1RM) will be assessed for each RT movements at baseline, during (each 3 months) and at the end of the program. RT intensities will go from 40 to 70% of 1RM, with 8 to 10 forms of exercise involving majors muscle groups.
OTHER	Stretching and Toning	Participants in the active control condition will take part in three 60 minutes stretching and toning sessions per week. Each session will start with a five-minutes warm-up, followed by fifteen min of body stretching exercises mainly in a seated position and finish with a five-minutes cool down. Participants will engage in four muscle-toning exercises (light intensity) using dumbbells or resistance bands, two exercises designed to improve balance, one yoga sequence, and one exercise of their choice. Intensity of stretching and toning sessions will be monitored with heart rate chest strap and should not exceed the light intensity zone as defined by the ACSM (64% of Heart Rate maximum or less and a Perceived Exertion lower than 11 on the 6 to 20 Borg scale).
