Bendy bamboo poles really do help people carry more than their own body weight and reduce the forces exerted on their shoulders by almost a FIFTH, study claims
Bouncing bamboo canes force people to adjust their step while carrying goods
This can save up to a fifth of users' energy compared to rigid poles, finds study
The poles also reduce forces exerted on the shoulders by 18 percent

구부러진 대나무에 숨겨져 있는 무서운 힘 새로운 연구에 따르면, 구부러진 대나무 장대는 정말로 사람들이 자신의 몸무게보다 더 많은 것을 나르는 데 도움을 준다고 한다. 짐을 운반하는 원시적인 기술은 수천 년 동안 아시아 전역에서 사용되어 왔다. 이것은 백팩을 더 쉽게 질 수 있도록 만들 수 있고 군인과 응급구조요원이 더 효과적으로 일할 수 있게 하는 열쇠를 쥐고 있다고 과학자들은 말한다. 캐나다 캘거리 대학의 생명공학자인 라이언 슈뢰더는 이 간단한 방법은 무거운 짐을 가볍게 해주며, 이런 기술을 사람들에게서 배울 수 있다고 말한다. 그 비결은 걷기를 더 적은 에너지 운동으로 바꾸어 덜 힘들이고 걸을 수 있도록 한다는 것이다. 유연한 대나무 통은 무거운 물건이나 재료를 운반하는 보행자들이 단단한 기국에 에너지를 5분의 1까지 절약할 수 있게 해준다. 황기철 콘페이퍼 에디터 큐레이터 Ki Chul Hwang, conpaper editor, curator |

Bendy bamboo poles really do help people carry more than their own body weight, according to new research.
The primitive technique for carrying loads has been used throughout Asia for thousands of years - and the modern world is finally latching onto it.
It may now lead to better backpacks - and hold the key to making soldiers and emergency workers more effective, say scientists.
Ryan Schroeder, a biomedical engineer at Calgary University in Canada, said the simple method lightens heavy loads dramatically - and we can learn from the people.
The secret is it forces them to adjust their stride - turning walking into a less strenuous exercise.
Flexible bamboo canes enable walkers transporting weighty goods or materials to save up to a fifth of their energy compared to rigid poles. Here a woman's gait is tested as she carries the pole
A computer simulation showed people moved with less effort when slightly offsetting their stride from the natural bounce of their bamboo poles
Mr Schroeder, a PhD student, said: 'These remarkable yet simple tools can potentially reduce energetic exertion and lessen sharp forces on the carrier.'
He's already trying to implement some of the lessons in a novel backpack design.
Mr Schroeder added: 'Westerners are only just beginning to catch on to this innovation.'
Flexible bamboo canes enable walkers transporting weighty goods or materials to save up to a fifth of their energy compared to rigid poles.
What's more they reduced the forces exerted on the shoulders by 18 percent when burdened with half their body weight - allowed them to carry incredibly heavy loads for miles.
