Exergame training-induced neuroplasticity and cognitive improvement in institutionalized older adults: a preliminary investigation.
Physiology & Behavior 2021 September 10
BACKGROUND: Prior research has reported cognitive improvements in elderly individuals when mental and physical exercise are practiced simultaneously, as in exergaming. However, the molecular mechanisms driving this beneficial response remain unclear. Moreover, there is robust evidence that regular exercise increases neurotrophic factors and promotes neuroplasticity, contributing to cognitive improvement. This research aimed to assess the impact of a 6-week Xbox 360 Kinect exergame protocol on cognitive function and brain-derived neurotrophic factor (BDNF) levels in institutionalized older individuals.
METHODS: Participants living in a long-term care facility were included. The intervention (Xbox 360 Kinect exergame protocol) was conducted individually and consisted of two sessions per week (40 min each) over 6 weeks. Participants' cognitive function (Montreal Cognitive Assessment, MoCA) was evaluated before and after the intervention. Blood samples (15 ml) were collected at the same time to measure BDNF levels.
RESULTS: Although there were no changes in total MoCA scores, exergame training improved the "language" domain and demonstrated a tendency toward an improvement in the "abstraction" and "memory/delayed recall" domains. Furthermore, BDNF levels were significantly increased after the intervention.
CONCLUSION: BDNF enhancement might mediate, at least in part, the cognitive changes induced by a 6-week Xbox 360 Kinect exergame protocol in institutionalized older adults.
