Numerous studies have confirmed that weight-bearing hiking is highly beneficial for muscles and bones. On one hand, weight-bearing hiking can strengthen leg muscles, prevent muscle loss in the elderly, which can lead to difficulty in going out and affect quality of life; on the other hand, weight-bearing hiking can apply pressure to the bones in the thighs, promoting the body to deposit calcium in the bones, increasing bone density, and preventing osteoporosis.
However, whether a weighted vest or a weighted backpack is better, this latest article I have compiled will provide the answer!
As early as 1986, scientists from the University of Nairobi and Harvard University studied the extraordinary weight-bearing capabilities of women from the Luo and Kikuyu tribes in East Africa. The results showed that these women could balance up to 20% of their body weight on their heads, and the energy expended while carrying the load was no greater than when walking without a load. This is an impressive physical feat-and also serves as a reminder that, in the midst of the backpack-based fitness craze, backpacks are not the only way to carry heavy loads, nor necessarily the best way.
This is the core observation of a new study published in the journal *Exercise and Sports Sciences* by David Looney and his colleagues at the U.S. Army Environmental Medicine Institute and several other institutions. In this study, their focus was on the energy required to drag heavy objects while wearing weighted vests. For military personnel and emergency responders, tactical vests are typically an indispensable part of their gear; For civilians seeking to exercise through marching (i.e., walking around while carrying heavy loads), weighted vests are a popular alternative to filling backpacks with bricks. But what are the differences between these two weight-bearing techniques?
