Why is HIIT Training Important for Older Adults?

Numerous studies demonstrate that cardiovascular exercise boosts brain fitness.

However, new findings from researchers show that high-intensity interval training (HIIT) improves executive brain function more than moderate-intensity, continuous aerobic training or resistance training over a 6-week training period.

Investigators conducted the study with 69 healthy, active older adults ages 61–75, collecting data on cardiorespiratory fitness and cognitive testing. Researchers concluded that all exercise is important for older adults’ but that HIIT training enhanced executive brain function improvements in the short term.
