This study was conducted to examine the possibility of Salicornia herbacea L. powder as a functional food beneficially affecting carbohydrate metabolism and antioxidant capacity. Twenty-four, 6-week old, maleSprague-Dawleyrats were classified into three groups: normal diet control (CON), high-fat diet control (HFC) and high fat diet + Salicornia herbacea L. (SHF). Related feed was provided to each group for 4 weeks. Weight gain rate increased most in the HFC rats, and the concentration of glucose was significantly high in both the HFC and SHF groups, compared to the CON group. The SHF group showed a significantly high expression rate of Glut 4 (21.36%), compared to the CON and HFC groups. The glycogen content in muscle was significantly high in both the HFC and SHF groups, compared to the CON group. There were significant differences in the malondialdehydecontent in muscles between the groups, with the content in the CON and HFC groups being significantly higher than the SHF group. All the groups showed a similar tendency to each other in the liver tissue as well. Concerning the expression of Cu,Zn-super oxide dismutase andglutathione peroxidaseproteins, the SHF group was significantly higher than the CON and HFC groups. Overall, the experiment result above implies a possibility that an intake of Salicornia herbacea L. powder can regulate weight by decreasing the weight gain rate, further suggesting its effectiveness as a functional food before exercise by increasing the energy storage capacity and antioxidant capacity.

Purpose: The cardiopulmonary exercise test (CPET) is an important clinical tool for evaluating exercise capacity and is frequently used to evaluate chronic conditions including congenital heart disease. However, data on the normal CPET values for Korean children and adolescents are lacking. The aim of this study was to provide reference data for CPET variables in children and adolescents. Methods: From August 2006 to April 2009, 76 healthy children and adolescents underwent the CPET performed using the modified Bruce protocol. Here, we performed a medical record review to obtain data regarding patient' demographics, medical history, and clinical status. Results: The peak oxygen uptake ($VO_{2Peak}$) and metabolic equivalent ($MET_{Max}$) were higher in boys than girls. The respiratory minute volume $(V_E)/CO_2$ production ($VCO_2$) slope did not significantly differ between boys and girls. The cardiopulmonary exercise test data did not significantly differ between the boys and girls in younger age group (age, 10 to 14 years). However, in older age group (age, 15 to 19 years), the boys had higher $VO_{2Peak}$ and $MET_{Max}$ values and lower $V_E/VCO_2$ values than the girls. Conclusion: This study provides reference data for CPET variables in case of children and adolescents and will make it easier to use the CPET for clinical decision-making.

Purpose: This study sought to investigate the effects of the McKenzie exercise program on forward head posture and respiratory function. Methods: Thirty adult men and women with forward head posture, aged 20-29 years, were randomly assigned to the experimental group (N=15) or the control group (N=15). Subjects in the experimental group performed the McKenzie exercises three times a week for four weeks, while subjects in the control group did not receive any intervention. Craniovertebral angle (CVA) was measured to quantify forward head posture, and forced vital capacity (FVC), FVC % predicted, forced expiratory volume at one second (FEV₁), and FEV₁ % predicted were measured to determine changes in respiratory function. The Mann-Whitney U-test was used to analyze pre-test differences in forward head posture and respiratory function between the two groups, and the Wilcoxon signed-rank test was used to analyze differences in forward head posture and respiratory function within the groups before and after intervention. The significance level (α) was set to 0.05. Results: A comparison of pre- and post-test measures showed that CVA significantly increased in the experimental group (p=0.001) denoting postural improvement, whereas no significant difference was found in the control group (p=0.053). All respiratory measures, i.e.,FVC, FVC %pred, FEV₁, and FEV₁ %pred, were significantly improved in the experimental group, whereas there were no significant differences in the control group. Conclusions: McKenzie exercise can be effective in improving forward head posture and respiratory function.
