Acute exercise improves memory
Exercising during the first stages of consolidation appears to be the most effective strategy
The coupling of the exercise stimulus with the memory formation process is essential
Rather than the type of exercise the physiological stimulus seems the key
![Page 49: The Effects of Exercise on Memory](https://reader030.fdocuments.in/reader030/viewer/2022012205/61de474cbb1b2a21ee2c4e59/html5/thumbnails/49.jpg)
Acute exercise can improve other (more declarative) types of memory
Long-term and acute exercise can be combined to maximize cumulative effects
![Page 50: The Effects of Exercise on Memory](https://reader030.fdocuments.in/reader030/viewer/2022012205/61de474cbb1b2a21ee2c4e59/html5/thumbnails/50.jpg)
Message
• Be smart, exercise (regularly) your heart to maintain cognition
• Combine different types of exercise at different intensities
• Place the exercise close to the exposure of information that you want to remember
• Combine acute and long-term exercise to maximize the effects on learning
