GC투여는 매일 아침 2mg/kg/q를 복강투여하였으며, 자발적인 저항성운동으로는 철망타워(Ø20cm×200cm)내를 자발적으로 오르내리는 승강운동을 실시하였다. 실험기간 중 체중증가량은 GC투여군(GS, GE)이 대조군(SS)에 비하여 통계적으로 유의하게(p<.05) 낮게 나타났다. 조직중량은 GC투여군(GS, GE)이 대조군(SS)에 비하여 낮게 나타났으나 체중 kg당 조직중량에서는 심장, 간, 신장에서 GC투여군(GS, GE)이 유의하게(p<.05) 높은 것으로 나타났다. 골 칼슘 농도는 대퇴골과 경골에서 GC투여·안정군(GS)이 다른 군에 비해 유의하게 낮게 나타났으며(p<.01, p<.001), 척골에서도 대조군(SS)에 비해 유의하게 낮은 것으로 나타났다(p<.001). Kang, H.S. Effect of voluntary resistance exercise on body composition, bone calcium concentration in glucocorticoid-injected rats. Exercise Science, 12(2): 307-318, 2003. The purpose of the study is to investigates effect of voluntary resistance exercise on body composition, bone calcium concentration in glucocorticoid-injected rats. To determine the effects of tower climbing exercise on hematological status in glucocorticoid injected rats as an aging model, 29 male Sprague-Dawley rats, 10 weeks of age, were assigned to three groups : a saline control group(SS, n=9), a glucocorticoid-sedentary group(GS, n=10) and a glucocorticoid-exercise group(GE, n=10). The GS and GE groups were given 2 mg/kg/day of prednisolone. The GE group voluntarily climbed the 200-cm tower to drink water from the bottle set at the top of it. Weight gain during the 8-week experimental period was greater in the SS group than in the GS and GE groups. And bone calcium concentration was greater in the GS and GE groups than in the SS group. The hematological parameters were not influenced by glucocorticoid administration with or without climbing exercise.

Effects of Tower Climbing Exercise on Arterial Blood Pressure and Endothelial Function in Streptozotocin-Induced Diabetic Rats

강형숙,윤진환 한국생활환경학회 2017 한국생활환경학회지 Vol.24 No.4

The aim of this study was to examine the effects of tower climbing exercise on arterial blood pressure andendothelial function in streptozotocin-diabetic rats. Male Wistar rats were divided into three groups: control group (CG;n = 10); diabetic control group (DG; n =10); diabetic exercise group (DEG; n = 10). Exercise training consisted of 8 weeksof tower climbing exercise. Endothelial NO synthase (eNOS) mRNA by RT-PCR were assessed. After a period of 8 weeksof tower climbing exercise, systolic blood pressure and plasma glucose were significant lower (P<0.05) in the diabeticexercise group than the diabetic control group. eNOS mRNA and plasma NO were significantly increased (P<0.05) in thediabetic exercise group compared with the diabetic control group. Present findings indicate beneficial effects of towerclimbing exercise in diabetic rats since it increased plasma NO and eNOS content in the aortic wall. In conclusion, longtermresistance training, under the tested conditions in this study, is able to prevent an increase in systolic blood pressure.

Inadequate nutritional status of iron could interfere with normal growth and might impair physical performance among the physically active athletes. We examined the relationship between dietary intake and hematologic profiles in female high school gymnasts. Data for dietary intake, anthropometric measurements and hematologic profiles were collected and relationships of the variables were analyzed. Main outcome measures 24h dietary recall method, food behavior variables, anthropometric indices and health variables. Age of the subjects ranged from 15 to 18y at the time of the experiment. Their mean value of body fat and BMI were 21.2±3.0 % and 19.5±1.3, respectively. Most of subjects consumed nutrients at levels less than 2/3 of the RDA for the Korean adolescent, except for vitamin C. The mean value of energy and iron intake were 1,367.2±360.9 ㎉ (74.9±38.0% of the Recommended Dietary Allowance) and 7.1±2.7 ㎎(38.6±15.8% of the RDA), respectively. Female high school gymnasts with low Hemoglobin (< 12㎎/dL) level generally had lower iron, vitamin C and energy intakes than high Hb(≥12㎎/dL) group, indicating poorer dietary patterns. Lower intake of iron has been associated with poorer exercise performance. Thus, it seems clear that maintaining good iron nutritional status could protect iron-deficiency anemia and improve the exercise performance ability and athletic power. We suggest that adequate food and nutrient intakes, especially iron, might help to maintain exercise ability in female gymnasts.

운동선수의 철분섭취에 관한 문헌고찰

Iron is an element to build hemoglobin (Hb) in the blood, and the functional element of enzymes such as Mb, cytochrome, catalase, and perixodase in muscles. Iron is an important material in sustaining oxygen transport system and supporting cell function. Mb transfers oxygen to a place where ATP produced. Aerobic metabolism requires oxygen and the oxygen is transferred by Hb. A majority of the iron combines with various elements in the body. Iron exists as heme and nonheme. Non-heme iron includes ferritin, hemosiderin, lactoferrin, transferring, phosphate compounds, carbohydrate, and heme iron includes hemoglobin, myoglobin, and cytochtome C. The majority of heme iron can be absorb as Hb and Mb, and its absorption rate is very high without disturbances. But the absorption of non-heme can be affected by other factors. Exercise induced anemia can occur by the depletion of serum iron and iron in the body. The causes of iron depletion in the body are reduction of food consumption, menstruation, abrupt growth, and reduction of meat consumption. However, the rate of anemia episodes in male are low, and iron requirements are low. The average man can have anemia and Hb urine. Iron depletion in the body can lead reduction of oxidation in the body. It is reported that the iron depletion can impair the physical performance and deliver tiredness and was by reducing th ability of oxygen transport. Also, it can happen when the iron absorption is lower than iron loss brealdng the iron balance. Iron loss can occur by mucos membranate, blood loss, and feces, about 0.6㎎, by skin cell and sweat about 0.2-0.3㎎, and urine about 0.1 ㎎ in a day. The iron absorption can affect by iron content in food, biochemical availability, iron storage, and red cell production rate. Non-heme by food consumption consists of basic iron, and vegetable and dairy products contains this. Heme iron is contained in meat, poultry, and fish. Iron absorption rate by food consumption is about 10% and ten folds of this is needed to meat the requirement. Hb intercepts oxygen in the lung, and transfer oxygen through the blood stream to muscle cell where it can be stored by Mb. Cytochrome can use oxygen to break down energy substrate for muscle contraction. It is reported that iron depletion can impair endurance performance and cause elevated lactic acid production in an average man. On the other hand, some others report its influence on V^·O_2max and endurance performance is not obvious. However, reports suggest that iron supplements are beneficial in iron depleted athletes.
