----- Nội dung dịch tự động từ ảnh ----- This bar chart shows the results of a survey carried out on 50 people aged between 13 and 55. The aim of the survey was to find out levels of participation in exercise in the four weeks before the interview. During this time, 68 percent of those interviewed walked for health and recreation, about one in six biked, and over half did some kind of sport. As can be seen from the chart, the most popular sports during this month were swimmiìng and diving, with almost 15 percent of those asked trying it at least once. This was followed closely by various health and fitness activities. Obviously, these results were determined to at least some degree by the weather. If the survey were to be repeated in the summer rather than the winter, we might, for instance, expect the popularity of soccer and golf to increase. Among the people who did not take part in any exercise during the month in question, the main reasons given for not participating were lack of time, cost, and general poor health.
