细节题
The widespread sedentary (久坐不动的) lifestyle has become a problem in America, fueling the rising obesity (肥胖) rate.
Now a new study finds that being surrounded by active friends can help a person living a sedentary lifestyle get more exercise each day. Researchers at the US Military Academy found that people in social groups where exercise is valued are more likely to be more active themselves. Lonely people are more likely to live sedentary lifestyles without another person around to give them a boost. The findings highlight the idea that the company a person keeps can be a boost to their overall health and direction in life.
Dr. Diana Thomas, a professor at a military school and study author said that the idea for the research came from real life experiences on the campus. Her team had noticed a trend of people becoming more interested in fitness and other activities once arriving at the school. This is not usually the case at other schools and workplaces, where there is no significant impact on fitness. Thomas believed that this trend could be the result of in-group social conditioning, where people will take part in activities that others around them are doing.
People whose data were gathered for the study were split into three groups based on their physical activity level—sedentary, moderately and extremely active. Moderately active folks were the most important for drawing people who are sedentary to become active, and to sustain that activity. Thomas explained that sedentary people would be unlikely to change their behavior when placed in a group of the extremely active, as it would seem unattainable.
