N/A Forty-six patients receiving maintenance $quot;conventional$quot; hemodialysis were studied before and after a 12-week conditioning program to determine the effects of physiologic and psychosocial functions. The subjects were assigned at random to either a exercise(n=25) or a control group(n=21). The subjects in the exercise group performed a combination of bicycle ergometry and treadmill walking two or four times a week for a total exercise time of 10-40 min per session. A low-level graded exercise treadmill stress test(GXT) were administered before and after training. Hematological and serum lipid profiles were also determined before and after training. Following training, there were improvements in physical work capacity(PWC) for the GXT(p$lt;0.05). Also there was increase in physical fitness(p$lt;0.05) compared with control. Although no significant differences in lowdensity-lipoprotein cholesterol, high-density-lipoprotein cholesterol and triglyceride, significant difference was observed for total cholesterol. Additionally, no significant changes were seen in hematological parameters, but psychosocial functions improved significantly after training. This study demonstrated that exercise training before hemodialysis can improve exercise capacities, physiologic and psychosocial functioning in endstage renal disease patients. Thus, exercise training seems to have beneficial effects on physiologic and psychosocial functioning in hemodialysis patients, and should be considered as a therapeutic modality for their medical management and rehabilitation.

In the past, weight-classed athletes in Korea had been known to engage in unbealthy practices with rapid weight loss. Thus, we participated in the survey of recent trends in their weight loss patterns, and then found their real problems in weight loss. The purpose of this investigation was to offer baseline data for foundation of policy, education program, and guideline of safety weigh loss. 500 weight-classed athletes in urban and some rural provinces were asked to complete a self-administerd questionnaire which was developed for this investigation. Before certification, the average weight loss was 6.5% of the initial body weight, and even more the athletes with a 7 day rapid weight loss over 5% was 16.3% out of weight-making" athletes. Their rapid weight loss was achieved by overtraining malnutrition, and dehydration. The beginning age of the recent weight loss practice is earlier than that of past. Questionnaire results indicated that coaches and the "other athletes" were the most frequently consulted on how to "make weight" whereas the professional was seldom consulted on this matter. In our opinion, weight-classed events are in urgent need of policy, education program, and guideline for safety weight loss.
