Unit 109 Get out of the swim
Unit 109 游泳运动体重并不会减少
Wait a minute-didn't we just tell you about the benefits of swimming?Well,there's something you should know:Swimming isn't the greastest exercise for losing actual pounds,according to at least one study published in the American Journal of Sports Medicine.
Researchers followed the progress of a group of moderately obese but otherwise healthy young women who were trying to lose weight by exercising without changing their diets.The women were divided into three exercise groups.Group one rode stationary bicycles,group two took brisk walks and group three swam laps in a pool.All of them slowly but steadily increased their daily exercise period to 60 minutes.After about six months,the bike-riders had lost 12 percent of their initial weight and the walkers lost 10 percent,but swimmers lost none!
However,keep in mind that swimming has been proven effective in improving muscle tone,and firm muscles contribute significantly to losing inches,if not pounds.
