2015年同等学力英语考前热身练习(14)

　　Researchers have found that short, intense exercise sessions prove to be healthier than longer, more moderate sessions with an equal caloric burn.

　　The study found that activities like running and jumping reduced participants’ risk of developing metabolic syndrome(代谢综合征)by two-thirds, compared with moderate activities like walking and leisurely bike rides that burned an equal number of calories.

　　Metabolic syndrome is a set of health conditions that significantly increase your risk of heart disease and type 2 diabetes(糖尿病).Insulin(胰岛素)resistance and extra weight around the middle-that dreaded “ belly fat” are two major health conditions associated with the syndrome.

　　The researchers used data collected from l,841 American adults. It is suggested that vigorous physical activity should be emphasized in public health guidelines for exercise.

　　Currently, the non-profit organization Society for Exercise Physiology recommends 150 minutes of moderate to vigorous physical activity per week for adults aged 18-64.

　　Avoiding metabolic syndrome isn’t the only reason to change your exercise routine. One study found that gym goers who totaled 150 minutes of vigorous activity a week looked about 10 years younger than those who skip the gym altogether, while another study found that physical activity can cut the risk of breast cancer by up t0 30 percent in older women at a healthy body weight.

　　Also in recent years, studies have determined that three minutes of intense exercise, three times a week, could be the equivalent to five one-hour sessions, reducing the risk of heart disease and diabetes.

　　Comment 1:

　　Exercising is very personal. Nobody can say which one suits you except yourself. I have been walking for 45-50 minute everyday for the past 10 years, and it’s fine with me now. I think walking is the best way to keep me healthy.

　　Comment 2：

　　Exercise is just like anything. Don’t overdo it but also don’t just use it as an excuse to say you are working out. It needs to be in a good range to give you a good sweat but don’t destroy yourself as well. The bottom line is to get out and exercise. It might not make you live longer but it definitely will make you healthier.

　　Comment 3：

　　Any exercise is good, short or long, fast or slow, especially the exercise in fresh air.

　　Comment 4:

　　I’ve always done 15-20mins but I don’t take breaks. I move from one machine to the next, after my first round, I grab some water and then do a second round and then I’m finished. 20mins solid, only one water break.
