Just 45 minutes of exercise a week makes you smarter
Just 45 minutes of exercise a week boosts the brain power of people 50 and over, research has revealed.
A review of dozens of previous studies found that even one session of moderate aerobic and resistance activity is enough to enhance people's alertness, decision-making and memory.
Scientists have long believed that exercising slows down the cognitive decline that occurs naturally as people move from middle to old age.
However, the new analysis is the first of its kind to show brainpower actually improves from staying fit.
Published in the 'British Journal of Sports Medicine', the analysis is also the first to identify the key role played by resistance training, such as weights or core strength activity, in boosting brain function.
The new analysis also assessed the benefits of exercises which combined both elements of aerobic and resistance training, such as circuits, as well as tai chi and yoga for people unable to undertake more intense activity.
All were found to benefit the ability to process information rapidly and stay alert. (© Daily Telegraph, London)
