A large review of studies confirms that exercise can be a good way to help reduce the frequency of falls in the elderly. The analysis, in the Cochrane Database of Systematic Reviews, included 108 randomized controlled trials with more than 23,000 participants. Their average age was 76, and 77 percent were women. As controls, the trials used either educational information about fall prevention, or no intervention at all.
