Combining Exergame Training with Omega-3 Fatty Acid Supplementation: Protocol for a Randomized Controlled Study...

Area of Science:

• Neuroscience
• Gerontology
• Nutritional Science

Background:

• Falls in the elderly are linked to age-related neuronal decline affecting motor and cognitive functions.
• Omega-3 fatty acids (FA) and exergames show promise in improving brain function in older adults.
• Investigating combined interventions may offer synergistic benefits for cognitive and motor health in aging populations.

Purpose of the Study:

• To assess the effects of combined omega-3 FA supplementation and exergame training on the elderly brain.
• To compare the combined intervention's impact on neuronal structure and function against exergame training alone.
• To explore potential improvements in motor and cognitive functions relevant to fall prevention in older adults.

Main Methods:

• A 26-week, parallel, double-blinded, randomized controlled trial involving 60 healthy older adults (>65 years).
• Intervention groups received either omega-3 FA (fish oil) or olive oil, followed by a 16-week exergame training program.
• Main outcomes measured via transcranial magnetic stimulation and electroencephalography; secondary outcomes included reaction time and gait parameters.

Main Results:

• The study is designed to compare the effects of the combined intervention versus exergame training alone on neuronal measures.
• Analysis will include motor evoked potentials, response-related potentials, reaction time, and spatio-temporal gait parameters.
• Statistical analysis will utilize effect sizes and ANOVA to determine significant differences between groups.

Conclusions:

• This study is the first to investigate the combined efficacy of omega-3 FA and exergame training on age-related neuronal changes.
• Findings are expected to elucidate the impact of this combined approach on brain health and function in the elderly.
• Results may inform strategies for mitigating fall risks and improving quality of life in aging populations.
