1 . Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.
Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses (球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.
There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.
Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.

3 . The dangers of sitting all day are obvious. Researchers have shown that remaining sitting for extended periods of time (like at your 9-to-5 desk job) can do harm to your health. While exercise is a big part of reducing the harmful effects of sitting, it was unclear how many gym periods were needed to help – until now.
A new study, published in The Lancet, shows the ideal formula for reducing the negative effects of a sedentary(久坐的)job. Instead of a fixed number of hours spent exercising, the ratio(比率)depends on how much you sit: people who work a typical eight-hour day should spend at least one hour each day moving. If you sit six hours a day, you should spend half an hour exercising. The research also indicates that the exercise doesn’t have to be all once – or rigorous(严格的). It can be spread throughout the day and be as simple as walking.
The team behind the study analyzed data from a pool of a million adults over the age of 45 in Western Europe, the United States, and Australia. Using previous data, the researches examined data from 16 published studies and used it to determine how much exercise is required to compensate for sitting. Their recommended daily exercise goal is higher than previous advice but not necessarily less achievable, given it can be completed throughout the day.
Fitting in an hour of exercise a day sounds especially discouraging if you have a desk job, but there are plenty of workouts you can complete before and after work. Even if it means taking a 10-minute walk during lunch, your body will thank you in the long run.
