The role of balance and strength training in falls prevention A range of exercise modalities have been studied with the objective of preventing falls, including balance exercises, strength training, flexibility, tai chi, and endurance training. These can be used as individual or group exercises in isolation or in combination. A large body of evidence supports the recommendation that balance, strength, gait, and coordination training is effective in reducing falls, and therefore it should be included as part of a multi- component intervention to prevent falls in older persons and may be considered as a single intervention. In most scientific trials, the exercise program has been longer than 12 weeks (1–3 times per week) with variable intensity. According to the latest meta-analysis, overall exercise reduces fall rates in community-dwelling older people by 21%. Greater fall prevention effects (rate reductions of 39%) are seen from exercise programs that challenge balance and involve 3 or more hours of weekly exercise. In addition to increased muscle strength in older adults, strength 10
