Is there a way to quickly recall(回忆) information just before taking an exam? Walking backward might be a solution. Scientists from the University of Roehampton in the UK said this activity can help people improve their short-term memory.
Scientists asked 114 volunteers to watch a video. After watching the video, they divided the volunteers into three groups. One group walked 10 meters forward. The second group walked 10 meters backward. The third group stood in one place. Then the scientists asked all the three groups 20 questions about what they saw in the video.
The scientists found that the backward-walking group got two more correct answers than the other two groups. When you walk backward, you see things from a different angle(角度) compared to walking forward. This difference helps people recall things that happened in the past.
And walking backward is not just good for the brain. It is also good for the rest of the body. Compared to walking forward, walking backward is more challenging. This can help us improve our fitness, says New Scientist. Walking backward uses more energy in a short time and burns more calories(卡路里).
In addition, walking backward is less stressful for our knees. It also keeps our spines(脊柱) strong, which can help to ease(缓解) stress in the lower back. This might be why many old people like walking backward.
