기존의 스포츠 시뮬레이터 제품들은 모션 플랫폼의 운동과 간단한 시각적 콘텐츠를 이용한 실감 표현에 집중되어 있고 놀이위주의 적용에 국한되어 있어, 사용자가 체감할 수 있는 오감 자극효과가 낮아 고실감 적용에는 부족하며, 전문 콘텐츠 부재로 인해 교육용 스포츠 시뮬레이터로서의 적용은 아직 어렵다. 본 연구에서는 다종목 교환이 가능한 다축 공통 플랫폼과 교환식 스포츠 모듈로 분리하여 공통 플랫폼의 운동 자유도를 4자유도(Surge, Sway, Heave, Yaw) 운동을 할 수 있도록 스포츠 플랫폼을 설계하였다. 이 플랫폼은 안정성을 보장하고 간섭을 최소화하는 데 목적이 있다. 이 플랫폼에 탑재되는 교환식 스포츠 모듈의 운동 자유도는 2자유도(Roll, Pitch)로 승마, 요트와 같은 다양한 운동이 적용이 가능하고, 독립적인 회전 2자유도의 체감형 시뮬레이터의 구현이 가능하도록 하였다.

Purpose : We investigated the effects of horseback riding and horseback riding machine exercise on the serum lipid profile in elderly individuals. Methods : Our study included 30 healthy elderly individuals who were randomly assigned to 2 groups: the horseback riding and the horseback riding machine exercise group, with each group comprising 15 individuals. The riding exercise program was performed 25 times a week over 12 weeks. The repeated measures analysis of variance was used to determine changes in serum lipid profiles before and after exercise 6 and 12 weeks after exercise. Results : An intergroup comparison of blood tests showed that triglyceride, total cholesterol and low-density lipoprotein-C levels were decreased in both groups after 12 weeks of the riding exercise program. However, both groups showed an increase in high-density lipoprotein-C levels, although this difference was not statistically significant. Conclusion : Horseback riding and horseback riding machine exercise showed a positive effect on the serum lipid profile in elderly individuals.

Purpose: The purpose of this study is to examine the effects of using a horseback riding simulation on static balance in children with cerebral palsy. Methods: This study was conducted with 30 children with cerebral palsy at levels I~IV in the Gross Motor Function Classification System (GMFCS), who were randomly divided into a control group and a hippotherapy group. Both the control group and the experimental group received NDT for 30 minutes per session, four times per week, for ten weeks, while the experimental group also received hippotherapy, 15 minutes per session, four times per week, for ten weeks, after the neurodevelopmental treatment (NDT). The horseback riding simulators JOBA (JEU7805, Panasonic, 일본) used in this study simulated actual horse movements; static balance was measured in each group before the exercise and five weeks and ten weeks after the beginning of the exercise using a pedoscan system (Diers Pedo, Germany). Results: The intergroup effects on static balance were tested, and the results showed no significant differences (p<0.05). Conclusion: The horseback riding simulation exercise was shown to be effective for the static balance of children with cerebral palsy. Therefore, additional studies should be conducted with more children with CP divided according to type.

승마, 사격, 골프 등 운동경기에서 현장 화면을 구성하는 배경 그래픽은 경기의 승패를 좌우하는 중요한 요소이다. 하지만 이들 경기는 현장에서 직접 해야 하는 한계성이 있으며, 운동경기의 게임이나 simulation에서는 실시간 운용인 이유로 배경의 사실감 표현이 떨어진다. 본 논문에서는 이 한계성 극복을 위해서 경기 현장에서의 사진을 3d graphic으로 변환하여 모델링 한다. z-depth를 이용한 원근감을 표현하기 위한 특수 기법을 분석 연구하여 운동경기의 VR(virtual reality) simulation 배경 개발에 관한 연구를 한다. 본 연구를 통하여 현장감 있는 운동 경기 VR 배경을 구현 하여 스포츠 과학과 디자인학 발전에 기여하게 될 것이다.

말의 관절(articulatio)이나 인대(ligament), 건(tendon), 건막(lacertus) 및 윤상인대(ligamenta annularia)에 생기는 부종(edema)은 말과 관계되는 모든 사람에게는, 즉 말을 기르는 사람, 말을 관리하는 사람, 그리고 또한 말과 관계되는 모든 수의사에게 늘 접하지 않으면 안되는 병 증상 중의 하나이다. 말이 자신의 능력을 최대한 나타내기 위해서는 부종이 없는, 소위 말하는 ‘깨끗한(clear)사지’를 가진 말의 상태(condition)가 되지 않으면 안된다. 부종은 말에게서 눈에 보이지 않는 만성적인 능력 감퇴를 일으킬 수 있고 때로는 심한 통증을 유발 시키므로써 심한 파행(laemness)을 유발하기도 한다. 그럼으로써 오랫동안 운동경기나 일반 승마에 이용을 하지 못하고 강제적인 휴식 상태로 가지 않으면 안될 때가 종종 있다. 수의 분야에서 지금까지 응용되고 있는 치료방법에는 말에게 휴식을 처방하는 것 외에 압박붕대를 착용 후 운동요법(평보, 수영 등)으로 치료를 하거나 찬물을 이용하는 방법, 열을 방생하는 연고(warm ointment)를 그 위에 바른다든지, 항염증 치료제(antiphlogistica), 이뇨제(diuretica)혹은 부종이 생긴 부위를 주사바늘 등을 이용하여 그 속에 들어 있는 액체를 빼어 내는 방법(punction)등이 이용되어왔다.

The purpose of this study was to verify exercise effect of horse riding exercise according to estimate basal physical fitness and activities of daily living(ADL) function in the aged. Participants were nineteen peoples who have no impediment of activity. They performed horse riding exercise using SRider(Neipplus, Co., Korea) at sixty minutes a day. Exercise has progressed three days a week for eight weeks. We measured trunk flexion, sit up, whole body reaction, leg strength and maximal oxygen uptake as basal physical fitness. Also three meter gait, single stance with eyes opened and single stance with eyes closed as ADL function were estimated once a month. The result of legs strength and whole body reaction showed the higher significantly than before the exercise. Moreover, the result of three meter walking ability only increased significantly among the ADL function. This means that horse riding exercise might be activated continuous muscular contraction with maintained tonus of muscle. We thought that continuous movement of horse riding could be lead to isometric muscle contraction in lower limbs. Our study found that horse riding exercise could improve lower strengths and muscle reaction for exercise effect. Also we suggested that horse riding exercise could be adapted to exercise methods that could provide rehabilitation and treatment enough for the aged or disabled person.

The purpose of this study was to analyze the 12-week horse riding exercise effect on the locomotion of a body and bilateral balance and flexion/extension of trunk during the sit-to-stand(STS) in elementary and middle school students. One-hundred eleven participants were divided into three groups. Each group was subject to a different horse riding exercise: control group(n = 36), 1 time/week group(n=37), and 3 times/week group(n=38). Two-way repeated ANOVA was used to compare weight transfer time(WTT), trunk flexion velocity(TFV), trunk extension velocity(TEV), mean rising index(MRI), mean weight asymmetry( MWA) among the groups, and STS changes in before and after 12 weeks. There was a group interaction in WTT, TFV, TEV, MRI, and MWA with different responses to horse riding exercise participation. There was a significant increase in 1 time/week group and 3 times/week group of WTT, TFV, TEV, and MRI. Additionally, MWA(an index of a capacity for bilateral balance) in lower extremity was decreased in 3 times/week group. It seems that horse riding exercise positively affected musculoskeletal function of the trunk and lower extremity by accelerating locomotion and bilateral balance.

The purpose of this study was to analyse the effect of posture correction & stabilization according to horse rider's(n=10) skill levels of novice(0wk), mid-skill(12wk) & skill(24wk) in walk & trot. First, Mean posture of 3 times experiments; Anterior & posterior leaning posture of trunk showed rather unstable according to progress of the stages of TD1, TO, TD2 phase, and also shoulder & elbow angle, which effects to the distance from bit to rein, showed unstable riding posture. There was close relationship between shoulder and elbow Angle in walk and hip, knee & ankle angle in trot. Second, Posture correction & stabilization according to riding skill levels; Anterior & posterior leaning posture of trunk did not show significant difference statistically but showed approaching tendency to trunk's vertical line and showed significant difference(p<.05) according to improvement of skill levels in walk & trot horse riding. Hip angle showed significant difference according to progress of the stages of TD1, TO, TD2 phase(p<.05) and showed tendency maintaining the larger thigh flexion according to improvement of skill levels in walk & trot. Knee angle showed more stable posture by maintaining the larger flexion between thigh and shank according to improvement of skill levels in walk & trot(p<.05). Ankle angle also showed tendency maintaining the larger plantar flexion of foot according to improvement of skill levels in walk & trot. When considering the above, regular horse riding program could be useful in posture correction & stabilization according to improvement of skill levels of novice(0wk), mid-skill(12wk) & skill(24wk) in walk & trot.
