The purpose of this study was to investigate the effect of somatotype on the VO2max and hormone (adrenaline and noradrenaline) during treadmill walking. Forty healthy men participated and were randomized to four groups: Male 1 (M1) group, Male 2 (M2) group, Male 3 (M3) group, and Male 4 (M4) group. M4 group is the largest body type, and M1 group is the smaller the body type. Participants walked at a speed of 3.5 km/h for five minutes at an incline angle of 0°, 5°, and 10° in the treadmill. Maximum oxygen consumption and hormone (adrenaline and noradrenaline) were measured. In the results, VO2max has significantly increased according to the degree of the treadmill inclination, and M4 group (larger body type) consumed more oxygen than the M1 group (smaller body type). In the hormone, there was a significant increase in adrenaline concentration after walking in all groups, and there was a significant difference in M1-M4, M2-M4 and M3-M4. The noradrenaline concentration significantly increased after treadmill gait in all groups, and there was no significant difference in noradrenaline between groups. This study suggests that the larger body type consumes more oxygen during walking, and treadmill walking contributes to an increase in the concentration of adrenaline and noradrenaline.
The objectives of this study were to find out the plant to enhance immune activity among 42 kinds of foods frequently consumed by the Korean elderly consisting of 5 food groups and 5 wild plants. Each sample was assessed the immunoactive effect by measuring NFkB/ AP1 gene expression, nitric oxide and cytokine production in RAW-Blue™ cell. Soybean sprouts of 47 plants showed the highest NF-κB/AP1 gene expression at the level of 1.13 ± 0.03 (O.D. 650 nm) and Soritae, sweet potato, banana, apple, garlic, crown daisy, cabbage and Ailanthus altissima also had high activity of NF-kB/AP1 gene in RAW-Blue™ cell stimulated by LPS. NO production of Ailanthus altissima was significantly higher than that of other plants and 16 plants of glutinous sorghum, black rice, Seoritae, Heuktae, sweet potato, banana, apple, garlic, mungbean sprouts, spinach, crown daisy, young pumpkin, cabbage, soybean sprouts, Actinidia arguta and Aster scaber were the next best activity. The above results selected 17 out of 47 plant samples. Moreover, soybean sprouts was significantly shown to increase TNF-α (1,509.55 ± 1.38 pg/mL) and IL-1β (54.56 ± 1.08 pg/mL) cytokines in comparison with RAW-Blue cell stimulated by LPS. According to the results of in vitro evaluation, the ethanol extract of soybean sprout increased the production of immune-enhancing cytokines by proliferation of macrophages. In addition, NF-kB transcription factor activity and NO production ability were excellent, and it was selected as a material having excellent immunological activity.
