Purpose: This study analyzed the muscle activity changes induced by motions of reaching forward and chest expansion that were examined from the bilateral muscles with rectus abdominis, external oblique, multifidus, and longissimus thoracic using Pilates cadillac instrument. Methods: Nine young adult women, who have no musculoskeletal disorder and any of chronic diseases, were participated. Surface electromyography system was used for recording of all signals produced by muscles, and then normalized as percentage of maximum voluntary isometric contraction (%MVIC). The paired t-test and repeated measures of analysis of variance was performed. Results: Reaching-forward motion showed a higher muscle activity from non-dominant external oblique muscle than that of the chest-expansion motion. During both reaching-forward motion and chest-expansion motion, MVIC values collected from dominant side of external oblique muscle were shown a significantly lower than the values obtained from non-dominant side (p<0.05). Conversely, %MVIC values in external oblique muscle collected from dominant side showed a significantly higher than the values obtained from non-dominant side of the same oblique muscle (p<0.05). Reaching-forward motion was caused a higher %MVIC on non-dominant external oblique muscle than that of the chest-expansion motion (p<0.05). Regardless of dominant or non-dominant sides, external oblique muscle was shown the highest activation rate of all the other muscles during reaching forward action, and longissimus thoracic muscle was shown the highest activation rate of all the other muscles during chest expansion action. Conclusion: Reaching-forward motion is suitable for activating an external oblique muscle, and chest-expansion motion is an effective enough in activating of longissimus thoracic muscle.

The aim of this study was to examine the effect of regular aquatic exercise on physical fitness, static and dynamic balance capability, muscular activity in elderly women arthritis patients. Subjects (N=22) were allocated one of two experimental groups: arthritis (ART, n=11), control (CON, n=11). All subjects from both experimental groups were participated in an exercise program that was designed for same exercise intensity and work volume, and exercise was performed three times a week (60 min-session-1) for 12weeks. %body fat and body mass index (BMI) was significantly decreased while lean body mass and muscle mass was significantly increased in both experimental groups. Overall physical fitness level was improved in both groups but revealing different patterns between groups. In addition, static and dynamic balance capability was also significantly improved in both experimental groups. In conclusion, the aquatic exercise applied to the elderly women was effective for improving not only their overall health status but also their static and dynamic balance capacity.

The purpose of this study was to investigate the changes of electromyogram activity of trunk and lower leg muscles during dynamic balance control in 20 healthy adult subjects when various experimental visual conditions were applied. Surface electromyography system was used for recording of any signals produced by muscles. Muscle activity was recorded from muscles, of which left and right sides of rectus abdominis, external obliques, longissimus thoracis, multifidus, vastus medialis, biceps femoris, gastrocnemius medialis, and tibialis anterior, and then normalized as percentage of maximum voluntary isometric contraction. All data obtained from experiment were analyzed using SPSS ver. 20.0, and two-way analysis of variance were used to determine statistical significance between two factors (3×2 factorial analysis, visual conditions vs. leg conditions). Statistical significance levels were set at α=0.05. There were significant different in biceps femoris and external obliques muscle`s activities between right and left leg, showing more prominent reduction in left leg when blind vision condition was given. Significantly higher muscle activities were shown in both sides of multifidus (p<0.05), vastus medialis (p<0.001), tibialis anterior (p<0.001) and gastrocnemius medialis (p<0.001) with sighted vision and blanking vision compared to the condition of blind vision. These results confirmed that muscle activity is prominently stimulated by visual information provision, and this implies that visual input may be a major factor for maintaining of the body`s balance control.

The purpose of this study was to investigate the effect of water and energy substrate intake on the volume of body fluid and percent body fat. Two experiments were carried out using young and healthy subjects. In the first experiment, 48 subjects consumed total volume of 1.2 L of water and body composition measurement was taken. In the second study, total 37 subjects were used, and randomly allocated to four experimental groups: control (CON, n=9), carbohydrate supplement (CHO, n=10), creatine supplement (Cre, n=9), and carbohydrate and creatine supplement (CHO+Cre, n=9). Carbohydrate was provided to intake 40 g for each time, 3 timesㆍd?¹ for 3 days, and creatine was given to consume 5 g for each time, 6 timesㆍd?¹ for 5 days. For subjects who were in CHO+Cre, carbohydrate was given for 3 days and creatine was given for 5 days. After consume 1.2 L of water, % body fat (%BF) and skeletal muscle mass increased by 3.3% (17.9±4.9% [pre] vs. 18.5±4.7% [post]) and 2.2% (26.7±6.6 ㎏ [pre] vs. 27.3±6.6 ㎏ [post]). With Consuming of energy substrate (either CHO or Cre), there was only significant increase in body mass (BM) in CHO + Cre. Interestingly this was induced by increased skeletal muscle mass rather than increased body fat mass. As far as body fat measurement is concerned, skin fold thickness was not affected by consuming energy substrate whereas %BF was shown significant increase when near infrared interactance measurement was adopted. Base on these results, following conclusions were drawn. Using bioimpedance analysis, water or fluid consumption would significantly ncrease in % body fat. Short term carbohydrate or creatine intake would not cause to increase in body mass and/or %BF. Short term creatine intake would not cause to increase in body mass and/or %BF. Intaking both carbohydrate and creatine simultaneously for short period of time may possibly cause to increase in total body mass, as well as skeletal muscle mass or %BF. Percent BF or total BF mass may differently evaluated by using different techniques, that needs to be examined far more researches.

본 논문은 관절염을 앓고 있는 노인여성(환자군; 65.25±5.9세, 11명)과 일반 노인여성(통제군; 64.50±7세, 11명)을 대상으로 12주간의 수중운동(주 3회)을 실시 한 후 동적평형성과 통증(통증자각도)의 변화를 알아보고자 실시되었다. 동적평 형성은 시각정보의 유무에 따라 개안 시와 폐안 시로 나누어 측정하였다. 12주간의 수중운동에 따른 개안 시 동적평형성은 관절염 환자군(p<.001)과 통제군(p<.05)에서 유의하게 향상되었고, 폐안 시 관절염 환자군에서도 유의하게 향상된 결과를 보였다(p<.05). 또한, 통증자각도(VAS) 평가에 의한 통증 변화는 관절염 환자 군의 10요인(푹신한 의자에 똑바로 앉아있기 힘든가, p<.01), 11요인(누워있을 때 통증이 덜해지는가, p<.05), 12요인(통증 때문에 일상생활에 지장이 있는가, p<.05), 13요인(통증 때문에 직장일 또는 집안일에 지장이 있는가, p<.01)에서 유의한 통증 감소가 나타났다. 본 연구 결과를 통해 12주간의 수중 운동은 골관절염 노인 환자에게 개안 시와 폐안 시 모두 동적평형 능력을 향상 시키고, 일부 통증요인 감소에 효과적인 운동임을 알 수 있었다 This study evaluated the dynamic balance and pain after 12 weeks aquatic exercise in old osteoarthritis patients. The dynamic balances were assessed using 2 different experimental conditions (Open Eye Condition; OEC, Closed Eye Condition; CEC). Twenty-two subjects were assigned one of the two experimental groups: arthritis group (ART, age=65.25±5.9, n=11), control group(CON, age=64.50±7, n=11). All subjects participated in the aquatic exercise program three times a week for 12 weeks. The dynamic balances (OEC (p<.001), CEC (p<.05)) capability were improved significantly in the ART group after 12 week aquatic exercise. Visual Analogue Scale (VAS) was decreased significantly [Factor 10(Soft chair, p< 0.01), 11 (Lying down, p< 0.05), 12(Handicap, p< 0.05), 13 (Work interference, p< 0.01)] in the ART group. In conclusion, aquatic exercise was effective in improving the overall health status and the capacity of dynamic balances and reducing the degree of pain in osteoarthritis patients.
