When it comes to exercise and the brain, almost all studies have focused on aerobic exercise.
Only a small number have specifically looked at how maintaining muscle strength by resistance training can promote cognitive health among older adults.
In 2007, researchers from Brazil demonstrated that six months of either moderate or high-intensity resistance training improved short and long-term memory and verbal reasoning among 62 senior men.
There’s more. Two years later, Australian investigators conducted a study with 154 seniors. They demonstrated that a 12-month group-based program of strength and balance training exercises improved fluid intelligence – the ability to reason and think flexibly.
