Effect of exercise training on hippocampal volume in humans: A pilot study
Effect of exercise training on hippocampal volume in humans: A pilot study : The pilot study on effect of exercise training on hippocampal volume in humans is based on the hypothesis that there is a direct effect of supervised exercise training on magnetic resonance imaging (MRI) estimates of hippocampal volume in healthy humans. The sample chosen for the study included eight men and five women. The sample size was adequate for the study because of the ethical reasons associated with the study.
A small sample size is also beneficial to the study because the researcher is guaranteed of obtaining information from all the respondents and one can easily monitor them. It also helps to avoid huge economic costs that are usually incurred by a large sample size. The independent variable for the study is supervised exercise training.

The findings of the study revealed that there exists a linear relationship between changes in cardiorespiratory fitness and hippocampal volumes whereby an increase in cardiorespiratory fitness with more supervised training tends to result in high hipppocampal volumes. However, it was also discovered that physiological characteristics and exercise training led to higher hippocampal volumes as compared to cardiorespiratory fitness.
The study also discovered that there was a positive relationship between hippocampal volume and memory performance in humans. More aerobic fitness increases one’s hippocampal volume which results in better memory performance. The study has been very educative because it suggests that hippocampal atrophy among aging people can be treated using aerobic exercise and other physiological benefits that are associated with it.
