Weight Training Helps Seniors' Brains Work Better

Exercise and weight training will keep us fit and strong, but what how does it help an aging brain?
A new study suggests it improves the sharpness of the brain. 155 women aged 65 to 75 were selected into either a 'resistance training' group or a 'balance and tone' group. The weight trainers trained for either one or two days each week for 12 months and the balance and tone group for two days each week. At the end of 12 months a standard cognitive test (the Stroop test) was used to assess brain function and performance.
Both resistance-trained groups (1 and 2 days) improved their performance by 10-12 percent compared to the balance and tone group. The authors concluded that "twelve months of once-weekly or twice-weekly resistance training benefited the executive cognitive function of selective attention and conflict resolution among senior women."
