One of the studies divided a group of seniors into two different six-month exercise courses one course consisting of aerobic exercise, the other consisting of stretching and toning.
其中一项研究将老人们分为两组：一组做有氧运动;另一组做伸展和无氧拉伸，为期6个月。
Again, we'renot talking about marathon-training here.
重申一次，运动量均为适度而非马拉松式。
The aerobic-training course gradually built its participants up to walking 45 minutes at a moderate pace three times a week.
有氧运动组逐渐让老人们养成了每周三次，每次正常走路45分钟。
At the end of the course, the people who completed the aerobic training showed significant improvements in attention-related mental tasks.
有氧运动训练结束后，参与者在注意力相关的智能测试表现明显有了提升。
The stretching and toning group showed little improvement.
而伸展和拉伸小组受训前后无明显差异。
