The purpose of this study was to investigate the effects of resting periods between exercise sets during isokinetic contraction on recovery from muscle fatigue, strength, heart rate, blood pressure, and lactate level. Sixteen women performed 10 repetitions of isokinetic exercise for three sets in three different conditions. During the sets, they rested 50, 100, and 150 seconds in each condition. And the results were: 1) In this population, the peak torque of extensor during the isokinetic exercise in 100 second resting condition was significantly higher than that in 50 and 150 second resting conditions (p<.01). The total work of extensor was significant in the second and third sets in 50 and 100 second resting conditions (p<.01). 2) During the isokinetic exercise, the heart rate was progressively increased as the sets were advanced in all resting conditions (p<.01). And the increase was significant during the second and third sets than the first in 50 second resting condition (p<.01), while it was significantly greater after the third set than the first in 100 and 150 second resting conditions (p<.01). 4) No difference was found between the resting periods in blood lactate level and blood pressure during the isokinetic exercise. However, differences were found between the sets in these variables (p<.01).

Purpose of this study was to investigate the health status and life style of middle-aged people in Daejon. The subjects expressed more fear for disease as getting older(p<0.01). Sixty six percent of the subjects have suffered in the past or suffer at present certain kinds of disease. The older they are, the more disease they have. The alimentary disease, neuralgia, and arthritis were the most popular disease. The eye strain and exhaustion of body were indicated more frequently in fifties than in thirties or forties(p<0.01). They considered excercise as the most important factor to maintain health status, and then moderation in diet, relaxation, rest, decrease of alcohol intake, no smoking. Forty three percent of them were non-drinker. The number of drinker was four times more in male than female and increased as getting younger(p<0.01). Only male revealed smoker and 29% of them smoked 10-20 cigarettes per day. The number of smoker decreased as getting older(p<0.01). Male played exercise more regularly than female and subjects have better exercise habit as getting older(p<0.01). This study suggests that practical programs for self-health control should be developed for playing exercise regularly for female and for considering nutrition, no smoking, and no drinking in the daily life for male.

The purpose of this study is to investigate the patterns of Korean traditional food use in the households of middle aged women living in Kyunggido and Incheon area Four hundred eighty seven housewives whose children were in middle school answered the questionnaire about Korean traditional food use patterns in ordinary days, national festive days and in private celebration or memorial days. Most households have used Korean traditional table setting called Bansang as daily meals(96.7%) and have used home-made Kimchi(97.3%). However, the use of home-made Jang such as soy sauce, soybean paste and red pepper soybean paste was not very high(64.3%). Most households have celebrated New Years day(99.6%) with Ddukguk and Manduguk, Chusuk(95.1%) with Songpyun, and fruits, Full-Moon day(95.1%) with Ogokbap, Namul and Brum. Dongji was celebrated with Patjug by 73.3% of households. However, Samjitnal and Danho were celebrated with Whajeon and Ssukjulpyun by only 18.9% and 43.8% of the households respectively. The households using Korean traditional food to celebrate the birthday, the 1st birthday of child, the wedding or to memorize the passing day of ancestors were 96.0%, 80.7%, 81.3% and 86.7% respectively. Compared to households of urban and nuclear family, households of rural and extended family tended to use significantly more Korean traditional foods in many occasions and showed significantly higher rate of using home-made Kimchi and Jang.

This nutritional survey was conducted from February 8 to March 10, 1994, in order to investigate the nutritional knowledge, food habits, nutritional attitude, food preferences and nutrient intakes of urban middle-aged women living in Daegu and Pohang district. The subjects of this survey were 164 urban middle-aged women living in Daegu and Pohang Area. The completely answered questionnaires were analyzed for nutritional knowledge, food habits, nutritional attitude, food preference and nutrient intakes of urban middle-aged women. The results obtained are summarized as follows: The subjects had a high level of perceived knowledge (82.9%), that is the knowledge that each subject believed she had, but the accuracy of the knowledge was only 66.1%. The average nutrition knowledge score was 8.26 out of possible 15 points, and food habit score was 5.50 out of 10 points. Most of the subjects belonged to 'Fair' or 'Good' food habit group, which is considered to be relatively good. With increasing age, the percentage of perceived knowledge, accuracy, and nutrition knowledge score were getting lower. But food habit score and nutritional attitude score were getting higher at 40's women than 30's women. The correlation between nutritional knowledge score and food habit score was low (r=0.0748). The correlation between nutritional attitude score and food habit score was low, too (r=-0.0653). Food preferences for kimchi, potato, cooked rice, beef, noodle, cabbage and milk were high. Average calorie and protein intake of the subjects were 1967.4±27.8 Kcal, 75.8±1.4 g respectively. Carbohydrate, protein and fat ratio on energy composition was 63.3%:15.5%:21.2%.
