The purpose of this experiment was to test whether a mechanical circulatory simulator (MCS), which has been developed in order to evaluate characteristics of artificial organs, could be used to simulate exercise stress tests. The MCS consists of an atrium, an aorta and a ventricle which is driven by a DC motor. It is important to reproduce natural hemodynamic conditions in the MCS. At first, a computational simulation model, which can simulate natural circulatory reactions to exercise stress tests, was developed. Utilizing an algorithm in the model, a blood pressure control system was installed in the MCS. A personal computer used aortic pressure feedback to calculate proper cardiac output, heart rate and total peripheral resistance to control the MCS. Hemodynamic data including aortic pressure, heart rate, cardiac output and total peripheral resistance obtained in the MCS was similar to that from exercise stress tests conducted on a goat using a treadmill (3.2km/h). As a result, the new MCS, with the blood pressure control system, is now considered more effective than previous simulators in exercise stress testing for the aged.

The purpose of this study was to compare the bone turnover between eleven young female rhythmic sports gymnasts(aged 19-21 yr.)and nine sedentary control female subject(aged 21-22 yr.). The gymnasts were training 4-6 hours per day, 7 times per week with dieting. Bone turnover was assesed using speciific biomarkers of formation(serum intact osteocalcin)and resorption(the 24 hours urinary deoxypyridinoline). The gymnasts had significantly lower percent fat and body weights than the control females. The gymnasts showed significantly lower levels of serum calcium but slightly higher urinary calcium concentrations compared with the controls. The gymnasts had significantly higher bone resorption and lower bone formation compared with the control females. The findings suggest that an increased bone resorption in the female rhythmic sports gymnasts may cause loss of bone mass which was probably due to the vigorous exercise training under dieting regimes.

The results of early work completed using bioelectrical impedance for body composition assessment was limited by technological problems. Most of the research has focused on bioelectrical impedance conducted at a frequency of 50 kHz. It has been recently determined that low- and high-frequency bioelectrical impedance measurements can be used to distinguish the volume of extracellular water (ECW) from the volume of total body water (TBW). Therefore, a multi-frequency bioelectrical impedance method allows an independent assessment of ECW, TBW, and intracellular water (ICW). Using dual energy X-ray absorptiometry (DXA; Lunar DPX-L) as a reference method, we examined the validity of bone mineral content and bone-free lean tissue mass (LTM) measured by a multi-frequency bioelectrical impedance instrument (MLT-100, Sekisui) using a number of frequencies ranging from 2.5 kHz to 350 kHz applied to the right side of the body. The subjects were 52 men and 109 women, aged 23 to 86 years (men: 53.2±17.37 yr, women: 52.5±17.07 yr). The average LTM determined by DXA were 49.4± 5.92 kg for men and 35.6±4.35 kg for women. Multiple regression equations developed in the present study for estimating LTM were: LTM=0.306X_1+0.003X_2+0.098X_3+3.44 (R=0.948, SEE=1.93 kg) for men LTM=0.169X_1+0.003X_2+0.186X_3+5.75 (R=0.917, SEE=1.76 kg) for women where X_1=Ht^2/R_<HIGH>, X_2=H^3/1000 and X_3=Ht^2/R_<LOW> an R_<HIGH> and R_<LOW> stand for resistance of TBW and resistance of ECW, respectively. These equations may be used to evaluate body composition for a wide range of Japanese adults with reasonable accuracy.

Human serum albumin (HSA) is a mixture of human mercapt-(HMA, reduced form) and nonmercaptalbumin (HNA, oxidized form), and is known to be one of the major extracellular scavengers for reactive oxygen species. Using a high-performance liquid chromatographic (HPLC) system with an ES-502N column, we studied the redox state of HSA for male Japanese fencing ("kendo") athletes (n=11) before and after an intense kendo training camp for 4 days. In order to clarify the antioxidative effect of propolis supplementation on the HSA redox state during camp, subjects were divided into two groups (placebo group, n=5; propolis group, n=6). A double blind test was utilized. The propolis used in this study was a product of Brazil (daily amount of propolis was 787.5mg). During camp, the observed decrease in the mean values of [HMA/(HMA+HNA)] (f^^-(HMA)) in the placebo group was significant (76.8±1.66% before and 63.0±2.29% after camp; P<0.05). Similarly, those values for the propolis group were also significant (77.0±0.94% before and 70.5±1.51% after camp; P<0.05). For the propolis group, however, the degree of the decrease in the f^^-(HMA) value was significantly small compared with that of the placebo group (P<0.05). In addition, the change in the f^^-(HMA) value of the propolis group during the training camp was roughly within the normal range of that of healthy male subjects previously reported (73.2±2.34%). These findings suggest that propolis may be an effective supplement to improve the redox state of HSA for kendo athletes in repetitive and highly intensive training camps.
