근육계를 이용해 체계적으로 근력, 파워 및 근지구력의 향상을 도모할 수 있는 효율적인 운동 방법.
? 근육을 경직시켜 신체의 유연성을 떨어뜨린다.
? 여성들의 신체를 남성화시킨다.
근력, 파워 및 근지구력은 서로 관련성이 매우 깊으나 각각의 다른 의미를 지니고 있음.
근력
① 동심성 수축 (concentric contraction)
근긴장도가 생성되는 동안 저항을 이겨내면서 근육이 짧아지는 근수축
예) 무게를 손에 쥐고 팔을 구부릴 때
이두박근의 운동
② 편심성 수축 (eccentric contration)
근긴장도가 생성되는 동안 저항이 근력보다 커서 근육의 길이가 길어지면서 일어나는 근수축

concentrates this bile, meaning that it reabsorbs some of the fluid from the bile to make it more potent. After a meal, bile is squeezed out of the gallbladder by strong muscular contractions, and passes through a duct into the duodenum. Due to the chemical makeup of bile, the contents of the duodenum are kept at an optimal pH level for digestion. The bile also plays an important part in allowing
