Document Summary
Study: resistance training promotes cognitive and functional brain plasticity in seniors with probable. Stage b/w normal cognitive decline and more serious decline leading to dementia. Significance: mci represents critical window for intervention, exercise can change trajectory of decline. Previous research: resistance and aerobic training have shown to improve cognitive performance and functional plasticity in healthy seniors and seniors with mci. Gap in knowledge: no intervention study has compared the efficacy of resistance vs. aerobic training at the same time for this population. Using the optimal exercise type can be an extremely useful tool for combatting symptoms of mci and slowing cognitive decline. Plasticity: reorganization or strengthening of synaptic cxns in specific neural circuits as a result of our experiences. Hemodynamic activity: rapid delivery of blood to active neuronal tissues. Stroop: an executive cognitive test to measure selective attn/conflict resolution. 86 elderly women 70-80 y. o. randomly assigned to 3 cohorts (aerobic, resistance and control (balance & toning))
