The Effects Of Exercise On Cognition, Mobility, And Neuroimaging Outcomes In Older Adults Without Dementia, Narlon Cassio Boa Sorte Silva

Electronic Thesis and Dissertation Repository

Cognitive decline is increasing with the aging population and, at present, there is no effective pharmacologic treatment available. Exercise interventions may impart protection against cognitive decline. A novel exercise approach is multiple-modality exercise (MME; aerobic, resistance, and balance exercise) with mind-motor training. Mind-motor training is a promising intervention in the study of cognitive function. Combining MME with mind-motor training may improve or maintain cognition and provide prevention of dementia early in the course of cognitive decline. Individuals with subjective cognitive complaints (SCC) comprise an at-risk group early in the spectrum of cognitive decline that could be targeted for prevention. The …

Cognitive Changes Following Multiple-Modality Exercise And Mind-Motor Training In Older Adults With Subjective Cognitive Complaints: The M4 Study, Narlon Cassio Boa Sorte Silva, Dawn P. Gill, Adrian M. Owen, Teresa Liu-Ambrose, Vladimir Hachinski, Ryosuke Shigematsu, Robert Petrella

Lifestyle Research Team

Background

We investigated the effects of multiple-modality exercise with additional mind-motor training on cognition in community-dwelling older adults with subjective cognitive complaints.

Methods

Participants (n = 127, mean age 67.5 [7.3] years, 71% women) were randomized to receive 45 minutes of multiple-modality exercise with additional 15 minutes of either mind-motor training (M4, n = 63) or control (balance, range of motion and breathing exercises [M2, n = 64]). In total, both groups exercised 60 minutes/day, 3 days/week, for 24 weeks. Standardized global cognitive functioning (GCF), concentration, reasoning, planning, and memory were assessed at 24 weeks and after a 28-week no-contact …

Multiple-Modality Exercise And Mind-Motor Training To Improve Mobility In Older Adults: A Randomized Controlled Trial, Narlon Cassio Boa Sorte Silva, Dawn P. Gill, Michael A. Gregory, John Bocti, Robert Petrella

Lifestyle Research Team

Objective:

To investigate the effects of multiple-modality exercise with or without additional mind-motor training on mobility outcomes in older adults with subjective cognitive complaints.

Methods:

This was a 24-week randomized controlled trial with a 28-week no-contact follow-up. Community-dwelling older adults underwent a thrice -weekly, Multiple-Modality exercise and Mind-Motor (M4) training or Multiple-Modality (M2) exercise with an active control intervention (balance, range of motion and breathing exercises). Study outcomes included differences between groups at 24 weeks and after the no-contact follow-up (i.e., 52 weeks) in usual and dual-task (DT, i.e., serial sevens [S7] and phonemic verbal fluency [VF] tasks) gait velocity, …

Hockey Fans In Training: A Pilot Pragmatic 1 Randomized Controlled Trial, Robert Petrella, Dawn P. Gill, Guangyong Zou, Ashleigh De Cruz, Brendan Riggin, Cassandra Bartol, Karen Danylchuk, Kate Hunt, Sally Wyke, Cindy M. Gray, Christopher Bunn, Merrick Zwarenstein

Lifestyle Research Team

Introduction Hockey Fans in Training (Hockey FIT) is a gender-sensitized weight loss and healthy lifestyle program. We investigated 1) feasibility of recruiting and retaining overweight and obese men into a pilot pragmatic randomized controlled trial and 2) potential for Hockey FIT to lead to weight loss and improvements in other outcomes at 12 wk and 12 months.

Methods Male fans of two ice hockey teams (35–65 yr; body mass index ≥28 kg·m−2) located in Ontario (Canada) were randomized to intervention (Hockey FIT) or comparator (wait-list control). Hockey FIT includes a 12-wk active phase (weekly, coach-led group meetings including provision of …

Optimization Of The Hockey Fans In Training (Hockey Fit) Weight Loss And Healthy Lifestyle Program For Male Hockey Fans, Wendy Blunt, Dawn P. Gill, Shannon Sibbald, Brendan Riggin, Roseanne Pulford, Ryan Scott, Karen Danylchuk, Cindy M. Gray, Sally Wyke, Christopher Bunn, Robert Petrella

Lifestyle Research Team

BACKGROUND:

The health outcomes of men continue to be poorer than women globally. Challenges in addressing this problem include difficulties engaging men in weight loss programs as they tend to view these programs as contrary to the masculine narrative of independence and self-reliance. Researchers have been turning towards sports fans to engage men in health promotion programs as sports fans are typically male, and tend to have poor health habits.

METHODS:

Developed from the highly successful gender-sensitized Football Fans in Training program, Hockey Fans in Training (Hockey FIT) recruited 80 male hockey fans of the London Knights and Sarnia Sting …

The Healthy Mind, Healthy Mobility Trial: A Novel Exercise Program For Older Adults, Dawn P. Gill, Michael A. Gregory, Guangyong Zou, Teresa Liu-Ambrose, Ryosuke Shigematsu, Vladimir Hachinski, Clara Fitzgerald, Robert Petrella

Lifestyle Research Team

BACKGROUND:

More evidence is needed to conclude that a specific program of exercise and/or cognitive training warrants prescription for the prevention of cognitive decline. We examined the effect of a group-based standard exercise program for older adults, with and without dual-task training, on cognitive function in older adults without dementia.

METHODS:

We conducted a proof-of-concept, single-blinded, 26-wk randomized controlled trial whereby participants recruited from preexisting exercise classes at the Canadian Centre for Activity and Aging in London, Ontario, were randomized to the intervention group (exercise + dual-task [EDT]) or the control group (exercise only [EO]). Each week (2 or 3 …
