Management of nutrient intakes through behavior-mordification can be important for improving exercise performance in athletes. The purpose of this study was to determine the effectiveness of nutritional counseling for improving exercise performance capability in athletes. The subjects were seven golfers and fourteen ju-do athletes from Hoseo university, and they have nor received professional hel[ from dieticians. Prior to nutritional counseling, their dietary intakes, lifestyles and dietary habits were evaluated. Nutritional counseling sessions were conducted by a trained dietician every 2-3 weeks for 3-4 month. After 5 counseling sessions, nutrient intakes, lifestyle and dietary habits were re-evaluated. Exercise performance capability was measured by maximal exercise stress test using treadmills. Individual data were assessed as quality index represents the better nutritional status. The common dietary and lifestyle problems were overeating binging, overeating, snacking and drinking alcohol prior to the nutritional counseling. After counseling sessions, the quality index of dietary habits seemed to decrease, especially in ju-do athletes, representing nutritional problems were resolved. Body fat and body mass index decreased in ju-do athletes, but not in golfers. Both athletes have shown to increase oxygen uptake at anaerobic threshold and maximal oxygen uptake status, which represents that the athletic performance capacity was improved after counseling sessions. Their respiratory quotients were decreased. In conclusion, nutritional counseling sessions over five times are an effective and efficient approach to change dietary habits to improve exercise performance capacity. Furthermore, clients can have good dietary habits and learn how to manago muscle strength by behavior modification through multiple nutritional counseling sessions.

Objectives: This study sought to assess the effectiveness of community-based nutrition counseling on improving nutritional status, managing complex chronic diseases, and enhancing the quality of life for elderly individuals with chronic conditions, particularly in older adults with high levels of food insecurity and multiple chronic illnesses. Methods: Thirty elderly subjects with diabetes and hypertension who were registered at local Senior Welfare Center received individualized nutrition counseling, based on their Nutrition Quotient for the Elderly (NQ-E) index. Over a 16-week period, they received tailored counseling and underwent various health and nutritional assessments. The final analysis included 28 participants after two dropped out. Data analysis was conducted using the SPSS v28.0. Results: The subjects were over 70, with multiple chronic diseases including diabetes and hypertension and predominantly female. After 16 weeks, significant improvements were observed in the subjects' grip strength, and HbA1c levels, as well as in their NQ-E scores, indicating improved dietary balance and diversity. There were no significant improvements in the 'Moderation' subdomain of the NQ-E index, suggesting that this aspect requires further attention in nutritional counseling. The subjects' nutritional risk scores (NSI) were also significantly decreased, indicating less nutritional risk. Lastly, as measured by the SF-36K, the subjects' quality of life showed significant improvement in several domains including physical role performance and social function. Conclusions: This study demonstrates that tailored nutrition counseling, based on the NQ-E index, can improve elderly health, manage chronic diseases, and enhance quality of life. This approach potentially broadens the scope of community nutritionists' roles within an aging society. However, additional research is necessary to evaluate these interventions' long-term effects and sustainability.

The purpose of the study was to develop an internet nutritional counseling program using an expert system to assist obese people to lose weight through behavior modification. The internet counseling program for weight loss was developed by the accumulation of knowledge dealing with eating habits and exercising behaviors in expert system tool, Knowledge Engineering Agent (KEA) by a dietitian without any help of computer expert. To accumulate knowledge into KEA, survey was performed in 150 obese people, dietitians reviewed and consulted each survey case, and the consulted contents were learned and accumulated into KEA. Survey questionnaire was the same as that of the internet consulting program, and it included general characteristics, dietary habits, lifestyle, and exercise patterns related to obesity. Also, the dietitian selected proper factors inferred from the survey questionnaire of each case, and added the conclusions for them. Conclusions were made for helping clients to correct bad eating behaviors and accumulate good behaviors to lose weight. Counseling was divided into two parts; a two-week part and a daily part. Two-week counseling was performed based on 4 step questionnaires, and daily counseling was done for daily food consumption and physical activity. When clients answered survey questionnaires in a counseling internet program, the recommendations on how to eat, to exercise and to deal with stress in a real time for each case, was given. In conclusion, a counseling internet program for weight reduction can be used to give advices how to deal with obesity in a man-to-man way in a real time using KEA where nutritional knowledge based on behavior modification for weight loss was accumulated.

본 연구에서는 인터넷상에서 일반 대중들이 행동 수정 방법을 통해 올바른 식습관을 비롯한 생활 습관을 가짐으로 체중 감량을 통해 정상적인 체중을 장기간 유지할 수 있도록 하기 위하여 전문가 시스템 툴인 KEA를 사용하여 실시간 상담을 해줄 수 있는 프로그램을 개발하였다. 전문가 시스템인 KEA는 MCRDR 이론을 사용하여 특정 분야의 전문가가 전문가 시스템에 관한 전문지식 없이도 시스템을 직접 구축 운용할 수 있는 환경을 구축하여 지식의 전문가가 직접 지식데이터 베이스를 구축하고 유지.보수하여 저렴한 비용으로 장기간 운영이 가능하다는 장점이 있다. 처음에 KEA로 상담할 수 있도록 지식을 학습시키기 위하여 체중 감량에 관련된 설문지를 작성하여 과체중 또는 비만한 사람 150명을 대상으로 설문을 받아 전문 영양사가 이에 대한 상담을 하고 이것을 KEA에 학습시켰다. 설문지는 인터넷 상담 프로그램과 같은 설문지를 사용하여 각 대상으 비만의 원인, 식습관, 생활습관, 운동 습관을 조사하였다. 체중 감량 상담은 행동 수정 이론을 적용하여 내담자가 스스로 잘못된 식습관 및 생활습관을 수정함으로써 점차 체중을 감량하여 평생 적절한 체중을 유지할 수 있는 방법을 터득할 수 있도록 상담하는 것을 원칙으로 하였다. 지식을 KEA에 학습시키는 방법은 조사한 설문을 바탕으로 case에서 적절한 항목값으로 추출하고 KEA에 지식을 만들기 위한 조건으로 추가한 후 이러한 조건에 맞는 상담 결론을 선택하고 추가하는 방식으로 KEA에 학습시켰다. 이 프로그램은 인터넷을 통해 일반인이 사용할 수 있도록 인터페이스를 만들었고 사용자가 프로그램에 들어가서 실시간으로 전문가의 상담을 받을 수 있다. 사용자가 인터넷 체중감량 상담 프로그램을 사용하기 위하여 화면에 있는 설문에 답을 기입하면 이미 축적된 KEA의 지식으로 실시간으로 상담의 결론을 내려주었다. 만약 사용자의 상황이 KEA에 축적되어 있는 지식으로 결론을 내릴 수 없으면 '결론없음'이라는 말이 뜨게 되고 이때는 전문가각 직접 이 상담 case를 분석하여 KEA에 지식을 축적시켜 점차 KEA의 지식을 확충시켰다. 결론적으로 전문가 시스템인 KEA를 이용하여 체중 감량의 원칙을 행동 수정 방법에 따라서 사용자의 개인에 맞는 방법을 체중 감량을 할 수 있도록 전문가가 일대일로 실시간으로 상담할 수 있도록 하여 건강하게 체중 감량을 할 수 있도록 하였다.
