The purpose of this study was to investigate the difference of cardiovascular risk factors according to gender and whether there is a correlation between gender of each variables. A total of 24 college students participated in this study and consisted of male (n=13) and female (n =11). To identify the present study, baPWV, ABI, and blood pressure were measured. In the case of baPWV, there was no significant difference according to sex both in right upper arm - right ankle and in left arm-left ankle. In ABI, there was no significant difference according to gender both right and left. In comparison of the blood pressure of the limbs, the systolic blood pressure of the right arm, the systolic blood pressure of the left arm, and the systolic blood pressure of the right arm in males were higher than that of the female, but the diastolic blood pressure did not show any significant difference according to sex. In the case of correlation, gender - specific difference was found in baPWV of the right arm. In the case of baPWV of the right arm, there was a significant correlation in 8 items in males, but only in 1 item in females. In conclusion, male baPWV can be used as an effective index, and right systolic blood pressure was a cardiovascular disease index that could be used appropriately for both men and women.

Exercise Science. 20(4): 367-378, 2011. The purpose of this study was to investigate the effect of different exercise intensity on blood CRP, WBC, WBC subsets and CK concentration. Eleven females (age 27.3±4.38, weight 58.2±4.92) participated in this study and performed 65% HRmax and 80% HRmax by treadmill. Subjects performed an isoenergetic bout of exercise equal to 250~300 kcal. Blood samples extracted from pre, immediately after exercise and recovery period (24 hour later). No significant increase was founded in serum CRP concentration after immediately exercise in both treatment. There are significant increase in CRP from baseline to 24 h post-exercise for 80% HRmax but there are no significant interaction with 65% HRmax. Blood WBC concentration significantly increased immediately after exercise and such exercise induced increase was significantly higher for 80% HRmax exercise than 65% HRmax. Blood neutrophil, lymphocyte and monocyte concentration significantly increased immediately after exercise and returned baseline value at recovery period but there was no significant interaction with different exercise intensity. Blood CK concentration was significantly increased immediately after exercise in contrast to pre exercise value in both treatment and continued to the recovery period. But there was no significant interaction with different exercise intensity.

In order to study the effects of bicycle exercise on blood composition, cardiorespiratory function and leg muscle power of youth, 42 males who aged 13-15 yrs were selected. Subjects were divided into 2 groups, bicycle exercise group and non exercise control group. Statistical method adopted for data analysis were t test. In the test of blood composition, Hct of bicycle exercise group higher than that of control group, and TCH and LDL-C of bicycle exercise group were significant lower than that of control group. Forced vital capacity, %FEV1.0 and MVV of bicycle exercise group higher than that of control group. Results of HR and O2 uptake at pre and during maximal exercise indicate that bicycle exercise increase of the reserve power during activity in youth. For the evaluation of muscle power, lower leg torque power were checked. The leg muscle power of bicycle exercise group were superior than that of control group. Results of this study indicate that the oxygen transportational ability and the muscle healthfulness were improved by bicycle exercise during adolescence.

The purpose of this study was to investigate the effects of acute aerobic exercise on HPAaxis(ACTH, cortisol) and lipid(TC, LDL, HDL) of adult men. Twelve men underwent three experimental trials; only night food ingestion(23:00hour) trials, a single bout of walking exercise trial immediately after night food ingestion at low intensity walking(90-100beat/min) for 30 min on a motorized treadmill and control trial(no food and no exercise). Each subject performed each trials in a randomized, cross-over design at intervals of 7days. Venous blood samples were drawn at next day after night eating(07:00, 20:00hours). HPAaxis did not show any significant change with only night eating and exercise after night eating. But blood LDL concentration of exercise trials after night eating lowered significantly at 07:00hours compared with only night eating trials. The present findings suggest that postprandial exercise after night eating may effective way to reduce LDL concentration rather than by only night eating with non-exercise.

This study compared body composition by dance type in collegiate female dancers. The study subjects included dance sports(n=17) ballet dancers(n=20), Jazzs(n=16), hip hop(n=15), and control(n=25). All subjects measured their body fat, BMI, WHR, and lean body mass(skeletal muscle mass and body fluid amount) and figured out the ratio of abnormally high(or low) fat%, high(or low) BMI, high(or low) WHR, and high(or low) lean body mass by bioimpedance electrical analysis. In the case of body fat percentage, the percent body fat of modern dance, ballet and jazz was lower than that of the control group, but hip hop was higher than other dance forms. In the case of skeletal muscle, modern dance, ballet, and dance sports group were lower than jazz and hip-hop. Over body fat ratio and over BMI were lower in the ballet group than in the control group and other dance forms, while the low body weight and low body fat ratio were higher in the ballet group than in the other dance group. The hip hop group showed higher over BMI than the other dance groups, but low skeletal muscle and lower body water were low. For low skeletal muscle and low body water, dance sports and ballet showed higher ratio than jazz and hip-hop. In conclusion, there was a partial difference in body composition according to other dance forms, and the difference in body composition is due to the difference in the characteristics of the dance form in which they participate or the level of individual activity, and further research related to this is desired.

The purpose of this study was to investigate the effect of different resistance exercise intensity on blood inflammatory factors(TNF-α, IL-6, CRP) and CK concentrations on women. Thirty female subjects(age 28.1±5.77years, weight 61.3±5.41㎏) were randomly assigned to high(3-5RM) and low resistance exercise(9-11RM). The high resistance exercise group performed four sets at 3-5RM with 3min rest between sets and the low resistance exercise group performed three sets at 9-11RM with 2min rest. Resistance exercise composed of seated bench press, pull down, back extension, sit up, leg curl, leg press, calf raise. Venous blood samples were taken from an antecubital vein by venepuncture and were collected at pre-exercise, immediate post-exercise and recovery period(24hours later). Blood TNF-α, CK concentration increased significantly immediately after exercise and such increase continued during recovery period in both treatment. Blood CRP concentration increased significantly after immediate exercise and recovery period. Especially such exercise induced increase of CRP is more higher in high intensity group than in low intensity exercise group. In conclusion acute resistance exercise increased blood inflammatory indices and muscle damage. Especially high intensity exercise resulted increased inflammatory response. Further study needed to elucidate the exact mechanism related to reactive oxygen response and regular resistance exercise.
