2.For years,experts have been encouraging people to exercise,using steps as simple as taking the stairs instead of a lift and walking to work,where possible.A recent study bolsters this advice---it shows that frequent active exercise throughout the day can have great health benefits.
The study,published in the magazine Preventive Medicine,found that just 2minutes of stair-climbing several times a day can lower total cholesterol(膽固醇),raise HDL ("good") cholesterol and improve the heartbeat in young women who do not have much activity during the day."such improvements may have important effects on the health of women,since,like cigarette smoking,poor fitness have been shown to be a high risk for heart disease and death in women,"said Dr.Colin Boreham with the University of Ulster in Belfast,Ireland and the fellow researchers of this study group.Furthermore,improvements in total cholesterol levels achieved in the study could cut the rate of heart disease in women by a third,they noted.
The team of researchers from Britain studied 12women between 18-22years old,before and after the exercise program.The women used a public staircase for about 2minutes a day for 5days a week.Compared with a group of 10women who did not take part in the stair-climbing program,the women who climbed stairs showed marked improvements in health and fitness levels after 7weeks.However,they did not show any signs of weight loss."A short-term stair-climbing program can give great health benefits to young women.Stair-climbing may be a particularly suitable way of combining exercise with an individual's daily lifestyle,"they pointed out.
Experts advise visiting your doctor before beginning a new exercise program.
