Muscle contraction is almost constant in volume at any time and only shortens in length. Consequently, the contracted muscles become thicker. The so-called muscle pain is thickened by the contraction of the muscles of the upper arm. Contracting as described above is common to the three types of muscles, but the rate of contraction is fast in skeletal muscle, followed by myocardium, and the plain muscle contracts very slowly. The contraction of skeletal muscle causes joints to move and exercise. The human body has about 400 skeletal muscles, large and small, so you can do fast and complex exercises. Since myocardium or visceral muscles are distributed in the wall of the organ, which is shaped like a bag, regardless of bone, the contents of the bag are pushed out as these muscles contract. For example, the heart pushes blood and the bladder pushes urine. 비앤비 여성전용아로마스웨디시 마사지
