EXERCISING for at least 45 minutes several times a week can boost brain power in the over-50s, research suggests.

Several types of exercise help improve thinking, attention, memory skills and executive function — mental skills that help people get things done, a new analysis of 39 studies found.

Aerobic exercise such as swimming, cycling and jogging; resistance training including weights, multicomponent training like combined aerobic and weight training and tai chi, were all “similarly effective”, experts writing in the British Journal of Sports Medicine said.

“Positive benefits to cognition occurred with an exercise intervention that included tai chi, or resistance and aerobic training, prescribed either in isolation or combined,” they said and benefits were irrespective of the current state of an individual’s brain health.
