The purpose of this study was to determine the effect of Korean traditional dance movement training on balance, gait and leg strength in elderly women who are forced to remain at home. Fifteen elderly women of an experimental group between the ages 65 and 75 years who have normal vision and passed the hearing and Romberg test, participated in the 12 weeks' dance movement training. Fourteen subjects of a control group were selected. Korean traditional dance movement training was developed on the basis of Korean traditional dance and music by the authors. It took approximately 50 minutes to perform the dance movement program. The subjects of the experimental group practiced dance training for 3 times a week during 12 weeks. During the 50 minutes workout, the subjects practiced 15 minutes of a warm-up dance, 25 minutes of a conditioning dance, and 10 minutes of a cool-down dance. The intensity for the conditioning phase was between 60% and 65% of age-adjusted maximum heart rates. The balance, gait and leg strength were measured prior to and after the experimental treatment. Total balance scores of the experimental group were significantly higher than those of the control group. Scores of sternal nudge, one leg standing balance and reaching up among 13 items have significantly increased after the dance movement training. Total scores of gait of the experimental group were significantly higher than those of the control group following the korean traditional dance movement training. Scores of experimental group in step height, path deviation and turning while walking among 9 items have increased significantly following 12 weeks of dance movement training. The leg strength of experimental group was significantly higher than those of the control group following the Korean traditional dance movement training. The balance, gait and leg strength have significantly correlated in the experimental group following the Korean traditional dance movement training. The results suggest that Korean traditional dance movement training can improve balance, gait and leg strength in home bound elderly women.

The purpose of this study was to investigate possibility of a forward gait with backward mechanism(dance gait) as rehabilitation and/or walking exercise by means of biomechanical variables. Thirteen professional women dancers(age, $21.1{\pm}1.3yrs$; height, $159.3{\pm}7.2cm$; body mass, $45.1{\pm}8.4kg$)participated in this study. We found that speed, stride length and double limb support time of a dance gait were more greater than backward gait, but stride width of dance gait less than a backward gait. Maximum RoMs, moments and powers of the lower limb joints on a dance gait were more frequent than a backward dance. These results were judged to be sufficient by the possibility of dance gait as rehabilitation and walking exercise.

Purpose : The purpose of this study was to evaluate the effects of the Hahoe mask dance on the gait and muscle activity in the elderly who lived at a elderly welfare facility. Methods : Dancing group was consisted of 20 subjects(over 70 years). The time of measurement was assigned in pre measurement, after 1 month, after 2 months. Subjects was received the Hahoe mask dance for three times a week during 8 weeks. The control group was consisted of 20 the elderly (similar age) who didn't received dancing. Assessment of gait function included the gait velocity, step time, stride, step length, it was analyzed in activity for 4 muscles (rectus femoris, biceps femoris, tibialis anterior, and lateral gastrocnemius). Results : Activities for muscles of control group was decreased in rectus femoris, bieps femoris, however, those of experimental group was increased significantly(p<.05). While control group showed decrease in the gait velocity per second (p<.05), experimental group showed statistically significant increase(p<.05). Control group had a significant long time than that of control group in gait time of right and left foot(p<.05). Control group was a little longer than control group in stride time of right and left foot(p<.05). Step length for control group was shorter than that for experimental group both foots(p<.05). Conclusion : In conclusion, this study confirmed that activities for 4 muscles by EMG have showed significant increases, so we will use a programme of muscle improvement in elderly community welfare faculty. We recommend that further research should explore the degree of muscle activity by larger sample sizes and longer follow-up periods.

The purpose of this study was to examine the effects of treadmill exercise on the aerobic function of dance majors in their 20s. The subjects consisted of 10 female Korean dance majors in their 20s as an experimental group and 10 normal female college students as a control group, and both groups conducted treadmill gait training. Their heart rate recovery (HRR), maximal oxygen uptake (MOU), maximal voluntary ventilation (MVV), and lactate recovery rate (LRR) were measured before and after the experiment. The comparison of changes in the subjects' aerobic function before and after the experiment showed that the experimental group gained more significant effects on HRR and LRR than the control group. Therefore, treadmill gait training may help Korean dance majors to improve their basic physical strength by enhancing their aerobic function, and the findings of this study are likely to provide basic data to support scientific exercise prescriptions.

Objective: The purpose of this study was to provide data on gait characteristics of K-pop professional dancers. Method: Participants were divided into four groups: male dancers (n=10, age: $28.2{\pm}3.4years$, height: $175{\pm}6cm$, weight: $68.9{\pm}5.6kg$), female dancers (n=10, age: $26.7{\pm}3.1years$, height: $162{\pm}4cm$, weight: $52.1{\pm}3.7kg$), non-dancer males (n=10, age: $25.2{\pm}2.6years$, height: $171{\pm}6cm$, weight: $66.4{\pm}5.3kg$), or non-dancer females (n=10, age: $26.2{\pm}3.0years$, height: $161{\pm}5cm$, weight: $56.4{\pm}6.7kg$). Twelve infrared cameras (Qualisys, Oqus 500, Sweden, 150 Hz.) were used to capture three-dimensional motion data. Gait motion data of professional dancers and ordinary persons were obtained. Results: K-pop dancers' dynamic stability during the female toe off event and the male heel contact event was better compared with that of ordinary persons in the front-rear direction. In addition, the results showed a significant difference in the margin of stability (MoS). However, the medial-lateral direction of both female and male dancers during heel contact and the toe off event was more stable compared with ordinary person, who exhibited an increased MoS than did the dancers. Conclusion: This study aimed to investigate the gait characteristics of K-pop professional dancers in comparison with ordinary persons using gait parameters and MoS. The stability of K-pop professional dancers' dynamic gait in the front-rear direction was better than that in the medial-lateral direction. Therefore, further studies in which the dance movements of K-pop dancers are sub-divided and analyzed will be necessary to reduce related injury.

PURPOSE: This study was conducted to investigate the effect of the virtual reality training (VRT) using 3-dimensional video gaming technology on spatiotemporal gait parameters in older adults. METHODS: The study participants were divided into two groups: the VRT group and the control group. Those in the VRT group were enrolled in a VRT, which was conducted for 60 min per day, two times a week, during the 6-week research. The Wii-Fit balance board game was used for the VRT intervention. The VRT consisted of 6 different types of games, namely, jogging, swordplay, ski jump, hula hoop, tennis, and step dance. A 3-dimensional TV was used for 3-dimensional display. Participants in both the groups received 3 sessions of fall prevention education, at the first, third, and fifth weeks. Their gait parameters were measured by using OptoGait. RESULTS: After 6 weeks of the VRT, the spatial gait parameters of the participants, that is stride length and step length, were significantly improved compared with those of the control group participants (p<0.05). The temporal gait parameters, such as velocity, cadence, stride time, and step time, also showed improvement after the completion of the VRT training (p<0.05). Both the temporal and spatial gait parameters of the VRT group participants showed improvement after 6 weeks of the program compared with those of the control group participants (p<0.05). CONCLUSION: The VRT using 3-dimensional video gaming technology might be beneficial for improving gait parameters to prevent falls among older adults.
