Resilience may be associated with the health of the hippocampus, a part of the brain that plays a key role in regulating the response to stress and memory. The extant literature shows less severe symptoms of PTSD in people who have a greater hippocampus volume. This may mean that having a healthier and larger hippocampus may serve as a buffer to the effects of stressors and allow a person to more readily overcome adversity. Research also demonstrates the beneficial effects of physical activity on the hippocampus, specifically through the upregulation of brain-derived neurotrophic factor (BDNF). Physical activity has been shown to have the ability to increase hippocampal volume. This is important because keeping the hippocampus healthy may prevent mental health disorders, specifically, dementia in older adults. Since resilience may be associated with an increased volume in the hippocampus, a person who is more resilient may benefit from physical activity even more than a person who is not resilient. Since the hippocampus is involved with memory, particularly short-term memory, the effects of resilience and physical activity may become evident when short-term memory is measured. This study is a part of a larger study done at UCLA's Department of Psychiatry and Bio-behavioral Sciences. To date, there has not been another study of which this investigator is aware, that has offered physical activity, a measure of resilience, and memory training together. The larger study included three groups, one of which received an intervention of one month of physical activity and memory training synchronously, another group which received the physical activity intervention and the memory training asynchronously (at a separate time), and the third, control group which received the memory training and a stretching component. In total there were 36 participants who completed the larger parent study for all three groups combined. When the groups were examined to test the influence of physical activity on memory, there was a deficit in memory found in the synchronous group, and a significant improvement in memory was found only in the asynchronous group. This may have been due to the taxing, multi-tasking aspect of the synchronous group. This study assessed resilience pre and post intervention in all three groups. The resilience data for the small sample was used to examine if resilience is a moderator between the effects of physical activity on memory and found that there is no significant relationship between resilience and physical activity and memory. This may be because no such relationship exists between resilience and the hippocampus. More research is needed to examine the neurobiology of resilience.
