고령여성의 아쿠아로빅 Noodle-Riding 동작 숙련도에 따른 역학변인 비교 분석

Abstract

A stationary bike ride and a water exercise are recommended for elderly people with osteoarthritis or a healthy knee-care regimen, and the best way to do both is noodle-riding. The purpose of this study was to analyze the difference between the experienced and the unskilled in the underwater noodle riding movement and to present the ideal posture and to propose the type of motion that the range of the hip joint use is larger than the existing motion. As a result of an experiment with 10 unskilled and 10 skilled people aged 70-75 with less than one year of experience participating in Aquarobics. First, the elapsed time between the skilled and the unskilled persons was long in the P2(that raise your knees and send your heel forward) and P4(to pull water up and send back heel), and statistically significant. Second, there was a statistically significant difference in hip joint(E1, E3, E6), knee joint(E1, E3, E5, E6) and ankle joints(E1, E4, E5, E6) between skilled and unskilled. Third, hip joint, knee joint , and ankle joint were significantly higher in the skilled. Fourth, the operating time of the Basic(P1, P2) and, Swing(P3, P5) was long, and there was a statistically significant difference. Fifth, the hip joints were statistically significantly higher in the Swing(E1, E5, E6) and Basic(E3). Knee joints were statistically significantly higher in Swing (E1, E2, E5, E6) and Basic (E4). Ankle joints were statistically significantly higher in Basic motion in the E1 event. Sixth, There was a statistically significant difference in the ROM of the swing in the hip joint and basic in the knee joint.

The conclusion based on the above results is as follows.

1. In order to perform accurate and efficient noodle-riding operation, prepare the posture with maintaining the hip, ankle angle of about 100° and knee joint at about 84°, increasing the time required for the P2 phase, pulling water by using the calf and foot sufficiently I repeat the rotation movement as pulling.

2. In the case of the skilled person, the swing motion is actively used in the E3 and E5 events to create a range of motion of approximately 90° using the hip flexor and extensor muscles.
