무용전공에 따른 남자무용수의 하지 가동범위, 기능적 움직임 및 근력 비교

Abstract

The objective of this study was to assess and compare among the range of motion, functional movements, and muscular strength of knee joint of male dancers, depending on dance type(ballet, modern dance, and Korean dance). Twenty one male dancers(each of seven from the three dance types) were recruited from those who have had no surgery or medical history in the lower limbs within the last six months. Measurements were taken of their range of motion(ROM) of hip internal and external rotations. Additionally, goniometric measurement of plantar-flexion and dorsiflexion of the ankle were done using a goniometer. To assess functional movement, all subjects completed the seven Functional Movement Screen(FMS) tests. Isokinetic dynamometry was (Humac NORM CSMi U.S.A) use for isokinetic strengthe measures. The ballet dancers showed larger ROM(right side; 34.29±6.07, left side; 35.00±5.77) than those(right side; 25.71±6.27, left side; 24.29±3.45) of modern dancers(right side; p=.046, left side; p=.003). The Korean dancers also presented larger ROM(right side; 37.14±5.66, left side; 35.00±6.45) than those(right side; 25.71±6.27, left side; 24.29±3.45) of the modern dancers(right side; p=.007, left side; p=.003). In relation to functional movement among the dance types, the ballet dancers were found to have scored higher(18.43±1.27) than those(16.57±0.78) of the modern dancers in the FMS tests (p=.020). No significant differences were found in isokinetic knee flexion/extension strength. In summary, It appeared that hip external rotation of ballet dancers and korean dancers were greater than those of the modern dancers. Additionally, ballet dancers seemed to have higher functional levels among the three dance types.
