Studies on the Improvements of the Rucksack (Part II)
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.2 Vol.2】
Old-type packs put most of the load on shoulders and imposed fierce vertical pressure on the easily damaged spine. A waist belt of packbag removes this pressure and strain and transfers the weight to the simple, strong, and well-muscled structure of hip and legs. But the safety of packbag for mountain use are questionable.
Comparative studies on the stabilities between rucksack and packbag changing the weight distribution, in going up and down the stairs or walking on the balance beam were carried out.
From the experimental results, it was suggested that packbag carrying load low are greater stable than rucksack.
