Whether it’s to help their dogs or themselves,about half of all Americans surveyed in a recent poll(民意测验) say they exercise regularly.According to the poll,most people walk for exercise a few times a week.About a third say they walk every day.
But are they kidding themselves to think a walk is really helping them?Should we all be running or jogging if we want to count that activity as good for us?Dr.Tim Church,who studies the effects of physical activity at Louisiana State University’s Pennington Biomedical Research Center,made a study about that.
Church headed a study with 464 postmenopausal(绝经后的) women who,for six months,came into the lab to walk a treadmill(跑步机) while researchers watched.
The first group walked for 73 minutes a week,the second 136 minutes a week and the third 190 minutes weekly.These women walked slowly,and could easily carry on a conversation.
“Surprisingly,the group that was only walking for 73 minutes a week slowly benefited a lot,”Church says.They say they’ve gotten more physically active from walking.They haven’t necessarily lost weight,but their pants fit differently.It’s because they have less belly fat,he says,which is a very good thing.This document from the American Heart Association lists dozens of studies showing similar benefits from walking.
