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 …

Exercise induces cytoprotective stress proteins in blood vessels (BV) and skeletal myofibres. The localization and extent of induction with different exercise intensities is unclear. Rats (n=10 per group) were run at high (HIEX; 30m/min) versus low-intensity exercise (LOEX; 15m/min) for 1hr, sacrificed 24hr later. Sections of the white portion of the vastus were immunofluorescently stained for Hsp70 and Hsp90. It was hypothesized that: 1) a greater abundance of Hsp70 and Hsp90 would be observed in BVs following HIEX, 2) due to earlier recruitment, larger BVs would have a more robust response than small BVs, 3) more myofibres surrounding BVs expressing …
