N/A This study employed 11 university soccer players for assessing anaerobic capacities related to ATP-PC and/or lactate system. It was investigated correlation among anaerobic capacities from Critical Power test, from Wingate test, and from Isokinetic test. Also, the study investigated regression formula which could expect anaerobic reserve(AR) from variables measured in Wingate and Isokinetic test. There were significant but intermediate correlation between AR and WIN5, (r= .62, P< .05) and WIN30(r= .64, P< .05). There was no statistically significant but intermediate correlation between AR and WIN10 (r= .52, P> .05). The study used stepwise method for multiple regression by Wingate variables to produce AR. The result showed that WIN30 had significant effect and indicated regression formula (Y= 1.3323(WIN30)-14737.758) to explain 41.2% variation of AR. Stepwise method was done for multiple regression on Isokinetic variables to produce AR`s inferred possibility by extensors TW of 60˚ /sec as regression (Y= 10.6737 (TW)+2083.9403) explained 42.9% variation of AR. In the correlation between measured variables of Wingate and Isokinetic extensors there was no significance of intermediate correlation in 60˚ /sec PT and WIN5(r= .53, P> .05) and in TW and WIN5(r= .56 P< .05) statistically. Also, There was significance of intermediate correlation in PT and WIN10 (r= .65, P< .05), no significance in TW and WIN10 (r= .57, P> .05), in PT and WIN30(r= .58), and no significance in TW and WIN30(r= .46, P> .05). In the correlation between measured variables of Wingate and Isokinetic extensors, there was significance of intermediate correlation in 180˚ /sec PT and WIN10 (r= .69, P< .05) and significant correlation in Isokintic 180˚ /sec PT and WIN30(r= .65, P< .05). The data suggested that anaerobic reserve assess true anaerobic ability not including the energy component of anaerobic glycolyses. Also, the study provides preliminary data on the anaerobic abilities in university soccer players as assessed by the Critical Power test, Wingate test, and Isokinetic test.

정진원 ( Jin Won Jeong ) 한국운동영양학회 2002 Physical Activity and Nutrition (Phys Act Nutr) Vol.6 No.2

The purpose of the study was to investigate relationship between anaerobic reserve (AR) from critical power test and anaerobic capabilities from Wingate and isokinetic test. Three different tests were administered to 12 high school sprinters on a Monark cycle ergometer and Kin-com isokinetic equipment. Means, standard deviations, Pearsons product-moment correlations, and simple linear regressions were obtained by using SPSS-Window program. To examine the important factors contributing to AR, stepwise regression analysis were performed using anaerobic capabilities from Wingnte and isokinetic tests as independant variables. Based on the findings of the study, the following conclusion has been derived: 1. There were significant moderate correlations of anaerobic reserve with WIN10, WIN20, and WIN30 respectively. 2. There were not significant correlations of anaerobic reserve with any isokinetic extensor and flexor variables. 3. The stepwise regression analyses revealed that only WIN30 contributed to predicting anaerobic reserve (72.9%) significantly. In conclusion, the results of the study demonstrated that the critical power test is a reliable and valid method for the measurement of anaerobic ability in the high school sprinters. The data suggested that anaerobic reserve assess true anaerobic ability not including the energy component of anaerobic glycolysis. Also, the study provides preliminary data on the anaerobic abilities in the sport of sprint as assessed by the critical power test, Wingate test, and isokinetic test.

Jong-Soo Kim, Ki Nam Lee, Jin-Joo Hue, Jun-Hyeong Kim, Bong Soo Kang, Sang Yoon Nam, Young Won Yun, Jae-Hwang Jeong2, Beom Jun Lee 충북대학교 동물의학연구소 2011 Journal of Biomedical and Translational Research Vol.12 No.1

To investigate the effect of carnosine on exhaustive exercise, swimming tests were conducted weekly with loads corresponding to 5% of body weight attached to the tails of mice, and the swimming time to exhaustion was measured. Eighty male ICR mice were divided into four groups, to which carnosine was administered at doses of 0 (control), 10, 50, and 250 mg/kg/day, respectively, for a period of four weeks. At the end of swimming exercise challenges, serum biochemistry, oxidative stress enzyme activity, and antioxidant enzyme activity in tissues were determined. Treatment with 250 mg/kg carnosine resulted in a significant increase in swimming times to exhaustion, compared to the control group in the first (P<0.01) and third week (P<0.05). Significantly lower serum lactate levels were observed after the swimming exercise in the carnosine-treated groups (10 and 250 mg/kg), compared with the control (P<0.01). Malondialdehyde levels in the liver (10 and 50 mg/kg carnosine treated groups) and skeletal muscle (250 mg/kg carnosine treated group) were significantly lower, compared with the control (P<0.05). Significantly lower protein carbonyl levels in skeletal muscle were observed in the 50 and 250 mg/kg carnosine treated groups, compared with the control (P<0.01). Superoxide dismutase and glutathione peroxidase activities in skeletal muscle did not differ significantly among the groups. These results indicate that carnosine may improve swimming exercise capacity by attenuating production of lactate and reducing oxidative stress in mice.

Won-Jeong Jeong(Won-Jeong Jeong),Byeong-Jin Kim(Byeong-Jin Kim),Sun-Shil Shin(Sun-Shil Shin),In-Joon Uh(In-Joon Uh) 한국임상움직임치료학회 2022 한국임상움직임치료학회지 Vol.2 No.2

Background In general, external rotation (ER) exercises are commonly used in rotator cuff retraining programs to improve stabilization ability. ER exercises at 90° of shoulder abduction are common and effective in strengthening the infraspinatus (ISP). However, if the ISP is weak during ER at 90° shoulder abduction, the posterior deltoid muscle (PD) is overactivated, which can lead to anterior translation of the humeral head. Therefore, the selective activation of ISP muscles is an important factor in rehabilitation. Objectives We investigated the muscle activities of the ISP, PD, and middle trapezius (MT), the ratio of the ISP to PD muscle activities, and the anterior translation of the humeral head in response to three resistance intensities during sitting external rotation (SITER) exercises. Methods A total of 12 healthy women recorded changes in the anterior translation of the humeral head using a load cell, the muscle activities of the ISP, PD, and MT, the ratio of the ISP to PD muscle activities using surface electromyography (EMG) during SITER under three different intensities [low (10-20%) medium (45-55%) high (60-70%)]. Results The ISP, PD, and MT amplitudes were highest at high intensity, followed by medium and low intensities during SITER (p < 0.001). The muscle activity ratio was significantly highest at medium intensity compared with low and high intensities (p = 0.031). The anterior translation of the humeral head was highest at high intensity, followed by medium and low intensities during SITER (p < 0.001). Conclusions Medium intensity (45-55%) was the most appropriate intensity during the SITER exercise. However, anterior gliding of the humeral head was the lowest at low intensity. Therefore, during ER exercises, we should think about how to control the anterior gliding of the humeral head.

Prurigo nodularis with HIV-infected patient

( Jeong Won Jo ),( Hae Bong Jeong ),( Yun Sun Moon ),( Do Seon Jeong ),( Eui Chang Jung ),( Chi Yeon Kim ),( Tae Jin Yoon ) 대한피부과학회 2016 대한피부과학회 학술발표대회집 Vol.68 No.1

Prurigo nodularis (PN) is a chronic dermatosis of unknown etiology characterized by discrete, intensely pruritic, symmetric, papulonodular lesions primarily on the extensor surfaces of the extremities. It is commonly seen in persons infected with human immunodeficiency virus (HIV) and with low CD4 counts. The pathophysiology of prurigo nodularis in the HIV infected population is particularly interesting and has not been investigated thoroughly. Prurigo nodularis is usually associated with HIV because it is easy to diagnose prurigo nodularis in HIV patients. However, it is difficult to diagnose HIV infection in a patient prurigo nodularis. We herein, report a case in confirming the HIV infection diagnosed with prurigo nodularis.
