10月18日（UPI）——根据西班牙的一项研究，体育锻炼可以降低老年人与虚弱有关的高死亡率。
这一发现证实了老年医学专家的建议，即体育锻炼有助于防止老年人发展成虚弱的危险：健康不良、摔倒、残疾和死亡。结果发表在本周《美国老年病学会杂志》上。
体育活动不需要费力，也可以包括步行。在先前的研究中，身体活动被证明能提高力量、平衡、敏捷、行走速度和肌肉质量。

研究人员分析了2000年至1981年在马德里的3896名参与者60岁及以上的信息。马德里自治大学的信息是在参与者的家中收集的，这些信息包括经过培训的人员的个人访谈和身体检查而获得。
用FRAIL量表测量疲劳、低耐力、行走受限、疾病和体重减轻。他们发现12%的人感到疲劳，7%的人耐力很低，比如爬楼梯，4%的人行走几百码的能力有限，2%的人生病，2%的人体重减轻。

Oct. 18 (UPI) -- Physical activity could lower the high rate of death associated with frailty in older people, according to a study conducted in Spain.
The findings, which were published this week in the Journal of the American Geriatrics Society, confirm advice by geriatrics experts that physical activity helps prevent older people from developing the dangers of becoming frail: poor health, falls, disability and death.
Physical activity doesn't need to be strenuous, and can include walking. In previous research, physical activity has been shown to improve strength, balance, agility, walking speed and muscle mass.

The researchers analyzed information from 3,896 participants 60 years and older in Madrid in 2000-01. Information by the Autonomous University of Madrid was collected at the participants' homes, including personal interviews and physical examinations by trained personnel.
Frailty was determined with the FRAIL scale that measures fatigue, low resistance, limitation in ambulation, illness and weight loss. They found 12 percent reported fatigue, 7 percent low resistance such as climbing stairs, 4 percent had limitation in the ability to walk several hundred yards, 2 percent were sick and 2 percent experienced weight loss.

Any of the five components of the FRAIL scale was linked to a higher risk of death from any cause. Pre-frail and frail people had a higher risk of death from cardiovascular disease than robust participants.
Broken down by frailty levels, 52 percent were in good health, 4 percent were pre-frail and 6 percent were frail.
During 14 years of followup, 1,801 participants -- 46 percent -- died, including 672 due to cardiovascular disease.

Deaths from cardiovascular disease among people physically active but also frail were similar to levels for pre-frail and inactive people.
"It's never too late to become active," the American Geriatrics Society said in a blog post. "Before starting on a new exercise program, check with your healthcare provider to make sure it's safe for you to do so. For the vast majority of people, the benefits of exercise far outweigh the risks."
