Pole climbing is ascending a pole which one can grip with his or her hands. The related activity of mast climbing describes ascending an object similar to a pole, but having a larger diameter which excludes gripping with the hands. In either case, it is normally assumed that climbers who view the activity as a ''gymnastic sport'' use only their bodies and limbs, without artificial aids. ==History== As ''sporting pursuits'' both pole and mast climbing may have begun as either martial exercises or physical training related to the invention and development of sailing ships, with the attendant requirements of scaling high masts. Pole climbing appears in some historical documents describing various ''cultural practices''. For example, Fray Diego Durán describes watching an Aztec climbing feat: ". . . to see an Indian standing on top of the 'flying pole' (for so they call it) anywhere between one hundred eighty and two hundred feet in height! He stands there with a trumpet in his hand, and, just watching him, those who observe become giddy . . . after having performed a thousand turns and tricks, he descends with an expression as serene as if he had done nothing!" 〔"The Book of the Gods and Rites and the Ancient Calendar", ca. 1577, trans. & ed. by F. Horcasitas and D. Heyden, 1971〕 Johann Friedrich GutsMuths (1759–1839) wrote the following in the late 18th century, in one of the first textbooks of "modern" gymnastics : "The climbing of the mast is far more challenging (pole climbing ), for the surface is smooth and the hands cannot go around it. Here, it is most necessary to have performed well on elementary exercises (with legs and thighs ). This activity is known, by the way, in several areas of Germany and Europe as an amusement for the general public. A few weeks ago one of my pupils climbed a tree trunk high. With nonchalance, he held on to the tree with one hand, tore off some leaves and flowers with the other, and fearlessly scattered them, looking down on his ascent. On such tree trunks one must not climb too high because of vertigo; if one loses his composure, he can slide down the tree, rather than fall." 〔"Gymnastik für die Jugend" by Johann Friedrich GutsMuths 1793, Berlin〕 Friedrich Ludwig Jahn (1778–1852) describes both pole and mast climbing in his seminal work of 1816 on gymnastic apparatus and exercises.〔"Die Deutsche Turnkunst" by Friedrich Ludwig Jahn 1816, Berlin〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pole climbing」の詳細全文を読む スポンサード リンク
