Some epidemiological studies suggested that gardening activities can contribute to suppression of cognitive decline. In our previous studies using functional Near-Infrared Spectroscopy (fNIRS), we reported the possibility of frontal pole (FP) activation of healthy older adults during gardening activities in the quasi-laboratory setting. The objective of this study was to examine the impacts of a three-month continual practice of the watering task in the actual gardening settings on the FP activation of healthy older adults. The participants were 18 right-handed healthy older adults without a diagnosis of mild cognitive impairment or dementia (M = 71.7 years ± SD 5.0, range: 63 - 84 years) who lived independently at home. We asked the participants to continue watering at home for three months in the same way as the research task in the fNIRS measurement. After a three-month intervention, the participants’ task performance improved compared with that of pre-intervention. In addition, the Oxy-Hb values in the right lateral FP during the third trial in the post-intervention measurement were significantly greater compared with the pre-intervention measurement. This study suggested that even a gardening activity with a small number of processes such as watering, if the activity is continued for a certain period of time, can suppress the decline of the FP activation of healthy older adults. Combination of various gardening activities has the potential to be a further cognitive training for activating the FP.展开更多
