The purpose of this study is to analyze the differences in foot type of female college students according to academic major in both feet. The subjects for this study were 216 female students who took liberal arts classes in Seoul. Dependent variables were students`` field of study -specifically whether or not they majored in physical education. Analysis of students`` foot type and Malalignment Syndrome were measured using Resting Calcaneous Stance Position (RCSP). There were five categories for RCSP angle: Severe Pes Planus (<-5°), Pes Planus (-3°~-4°), Pes Rectus (±2°), Pes Cavus (+3°~+4°), Severe Pes Cavus (>+5°), x2 analysis was χ used for statistical analysis. RCSP for all subjects (432 feet) occurred at the following frequency: Pes Planus(43.9%), Pes Rectus(43.8%), and Pes Cavus(12.3%). These levels were different for physical education majors, with Pes Planus at 42.6%, Pes Rectus at 49.4%, and Pes Cavusat 8.0%. Non-physical education majors exhibited Pes Planus at 45.0%, Pes Rectus at 39.9%, and Pes Cavus at 15.1%, 15.3% (33 subjects) of all students had Malalignment Syndrome, In conclusion, 56.2% of female college students had a foot deformity. There was nearly four times more Pes Planus than Pes Cavus. According to these results, exercise can be prescribed to alleviate foot deformities, especially supination. Severe pronation and supination problems appeared less amongst students not majoring in physical education. Thus, although exercise might be one cause of foot deformity, it can also help resolve problems with over-supination. Further study will be needed to understand and resolve the specific mechanism of over-supination.

수중 넘어짐 예방운동이 여성 노인의 체력 및 보행에 미치는 영향
김유련 이화여자대학교 동작과학연구소 2009 이화체육논집 Vol.12 No.-
본 연구의 목적은 수중 넘어짐 예방운동이 노인의 생활체력 및 안전한 보행향상에 효과가 있는지를 규명하는 것이다. 대상자는 서울 소재 여자대학교 평생교육원에서 운영하고 있는 수중 넘어짐 예방운동반에 자발적으로 등록한 60세 이상 여성 노인 7명을 대상으로 하였다. 수중 넘어짐 예방운동 프로그램은 주 2회, 1회당 90분, 13주 동안 실시하였다. 13주 동안 수중 넘어짐 예방운동을 실시한 결과 체력에서는 상·하지 근지구력, 유산소성 지구력, 민첩성 및 이동균형, 전후 좌우 동적 균형능력 그리고 보행 시 균형능력이 향상되었고, 보행능력을 평가하기 위한 지면반력에서는 보행 시 지면과 닿는 순간의 충격변인은 수직, 좌우 방향 모두에서 감소하여 충격을 완화시키는 능력이 향상되었다. 수중 넘어짐 예방운동은 여성 노인의 생활체력 중 유산소성 지구력, 상·하지 근지구력, 민첩성 및 보행균형, 전후 좌우 동적 균형, 보행에 효과가 있으며, 보행의 충격흡수에도 효과가 있다는 결론을 내릴 수 있다. 이것은 수중에서 하는 넘어짐 예방운동이 물의 부력을 이용하므로 체중부하가 감소되어 관절압박력(Compressive Force)과 생체역학적 스트레스(Biomechanical Stress)가 감소하여, 움직이는 동안에 관절에 미치는 부하는 줄어들고 대신 물의 점성과 저항으로 굴근과 신근의 균형이 향상(Arient, 2002; Hurly & Turner, 1991)되기 때문이다. 또한 부력은 안정성을 감소시켜 균형능력을 향상시키는데 효과적이다. 물 속에서 하는 운동은 무게중심의 위치를 고정시키지 않고, 다방향의 운동 조건을 제공하여 넘어짐을 예방하기 위한 체력, 동적 균형 그리고 전정계기능에 효과적이므로 노인들에게 넘어짐 예방을 위해 추천할만한 운동이라고 말 할 수 있다. The purpose of this study was to investigate the effects of Fallproof exercises on Physical Fitness and Gait in Elderly Women. Seven female attendees of a local adult education center over the age of sixty served as subjects for this study. Subjects exercised in water twice a week for ninety minutes per session over a thirteen week period. After thirteen weeks, there was a significant difference in four physical fitness variables. Muscular endurance in the upper and lower extremities (via the bicep curl) increased for both the right and left arm (t=-2.346, p<0.05) and (t= -3.165, p<0.01) respectively, while in the lower body, there was improvement in the results for the stand-up / sit-down test (t=-2.776, p<0.05). The step test showed improved cardiovascular endurance (t=-2.865, p<0.05). Both agility and dynamic walking balance improved through the tandem walking (t=2.277, p<0.05) and sharpened tandem walking (t=2.299, p<0.05) tests. At the end of the test period, there were significant differences for balance in all directions. Anterior / posterior balanced improved at sector one (t=-3.07, p<0.01) and five (t=3.60, p<0.01) and at the mean (t=3.69, p<0.01). Lateral balance improved in sector two (t=-3.93, p<0.01), three (t=-2.93, p<0.05), four (t=-2.30, p<0.05), five (t=3.46, p<0.01), and at the mean (t=2.96, p<0.05). There was a significant difference in the vertical and anterior / posterior passive impact variables. The vertical number of passive impact peaks (t=6.97, p<0.01), vertical maximum passive impact peak value (t=4.32, p<0.01), the vertical maximum passive impact loading rate (t=4.22, p<0.01), and vertical impact impulse (t=3.78, p<0.01) all decreased. In addition, the lateral number of impact peaks (t=3.75, p<0.01) decreased as well. These results demonstrate that aquatic Fallproof exercises can have a beneficial effect on elderly physical fitness factors including flexibility, muscular endurance, agility / dynamic walking balance, and also absorbing shock. Normally, Fallproof exercises are performed on the ground, but practice in an aquatic environment allows for greater safety and stability. Furthermore, the improvements from tandem walking, and sharpened tandem walking indicate an increase in fine muscle control. This increase can also be visible in the decrease in impact variables. As subjects gained more control over their fine muscles in the lower leg and the foot, it is possible that their footfalls were consistently less harsh. Aquatic Fallproof exercises are multidirectional exercises with a movable center of gravity. The aquatic aspects of these exercises include water resistance, reduced stress, and impact via water pressure and buoyancy. As such, these exercises would be ideal for elderly who are at high risk of falling during regular standing exercise.
