  • If a controlled sensory stimulation is given to the specific receptors, a reflex movement and motor engrams is achieved by the principle of neurophysiology. Based on this theoretical background, we choose 80 healthy person(male 40,female 40) and compare chronaxie of before stimulation with after stimulation. Also we measured chronaxie with same method. Stimulation was applied to the muscle belly by tapping. The results are summarized as follows; 1. The mean value of rheobase measured from the proximal part of upper extremity is 3. 56mA for male, 4.04mA for female. 2. The mean value of rheobase measured from the lower extremity is 4.19mA for male, 4. 37mA for female, which is higher than that of upper extremity for both male and female. 3. The mean value of chronaxie from the proximal part of upper extremity is 0.91msec for male, 0.87 msec for female, which means male is higher than female, and the average is 0.82msec. 4. The mean value of chronaxie from the proximal part of lower extremity is 1.04msec for male, 1.14msec for female, which means female is higher than male. 5. The decrease of rheobase after stimulation is prominent at the triceps brachii for male, biceps brachii for female. 6. The decrease of rheobase after stimulation is prominent at the tibialis anterior for both male and female. 7. The decrease of chronaxie after stimulation is prominent for both male and female at the triceps brachii from upper extremity and at the tibialis anterior from lower extremity for both male and female.

  • PURPOSE: The study examined the relationship between the knee function score and knee strength and muscular endurance of an elite female handball athletes according to their position in the team. METHODS: Thirty handball athletes participated on the study: 12 front positions, 12 back positions, and five goalkeepers. The knee function score consisted of symptoms, pain, daily activity, sports and recreation, and quality of life. In addition, CSMI (Cybex, USA) was used to measure the strength and muscular endurance of the knee. The muscular strength and muscular endurance were measured at an angular velocity of 60°/s and 180°/s, respectively. RESULTS: The overall items of the knee function score showed a significant difference (p = .017), and goalkeepers had significantly higher scores than the back positions. In addition, significant differences were observed in all five items depending on the position (p ≤ .05). On the other hand, both the flexor and extensor muscles of the knee strength and muscular endurance were not significant. Moreover, there was no correlation between the knee function score and the knee strength and muscle endurance. CONCLUSION: Elite female handball athletes have different knee functions score depending on their position in the team, but the, strength and muscular endurance of the knee were similar for each position. Furthermore, the knee function score showed no correlateion with the strength and muscular endurance of the knee.

  • BACKGROUND/OBJECTIVES: A large number of studies on anemia have focused mostly on pregnant women or children. The vegetarian population, which is another potential risk group for anemia, remains largely unexplored. Therefore, this cross-sectional study examined the associations of the sociodemographic, lifestyle, nutritional, and psychological factors with the anemia status among female adult vegetarians. SUBJECTS/METHODS: A total of 177 female vegetarians were recruited from a Buddhist and Hindu organization in Selangor, Malaysia. The participants completed a self-administered questionnaire, which analyzed their sociodemographic characteristics, physical activity level, sleep quality, depression, anxiety, and stress. The body weight, height, waist circumference, and body fat percentage of the participants were also measured. A 3-day dietary recall was conducted to assess their dietary intake. Blood samples (3 ml) were withdrawn by a nurse from each participant to determine the hemoglobin (Hb) level. RESULTS: The findings revealed 28.2% of the participants to be anemic. The age group (AOR = 2.46, 95% CI = 1.19-5.05), marital status (AOR = 2.69, 95% CI = 1.27-5.71), and percentage of energy from protein (AOR = 5.52, 95% CI = 1.41-21.65) were the significant predictors of anemia. CONCLUSIONS: Anemia is a public health problem among female vegetarians in this study. Health promotion programs that target female adult vegetarians should be conducted to manage and prevent anemia, particularly among those who are married, aged 50 and below, and with an inadequate protein intake.

  • The purpose of this study is to explore the ways of savoring of physical activities in middle-aged women based on the savoring theory of positive psychology. The first step was to understand the background of exercise participation experience and to provide basic information about savoring method. In the second stage, we used the open questionnaire to collect the savoring methods used during the exercise, and then, in-depth interviews were used to specify the savoring method. Open questionnaires were categorized according to the similarity of content and then nominated based on the savoring method. In-depth interviews were conducted to explore the cases of each method in detail. As a result, middle-aged women were found to use the savoring methods such as sharing with others, celebrating, comparing, feeling fine, blessing, expressing with behavior in physical activity. Through in-depth interviews, each case of savoring was embodied based on the savoring theory of positive psychology. Based on the results of the study, the possibility of applying the savoring method in the field of exercise instruction of middle-aged women and possibility of developing the savoring related program were discussed.

  • This study was aimed to analyze experiences of conflicts that women confront by participating in a conservative sport, baseball, and to figure out how they cope with these conflicts. In this respect, in-depth interviews were performed targeting 18 women who have been participating in a team registered in Women's Baseball Association for more than 1 year. Interview data went through classification of meaning and an analysis process of conceptualization and led to the following conclusion. First, the women's conflicts from their participation in baseball activities were revealed as the conflict between workplace and leisure activity, the conflict between significant others and leisure activity(objection by family and severance of interpersonal relations), and the conflict between sociocultural prejudice and leisure activity. Second, female baseball participants' strategies to cope with conflict situations were classified as making a group of supporters by persuasion and negotiation, active strategies(my own way and priority of life), and evasive measure(telling lies and avoidance of conflicts).

  • The purpose of this study was to explore how SCUBA diving instructors' perception on their divers affects the buddy selection process in SCUBA diving clubs. For the purpose of this study, 6 people who have more than 5 year experiences and have been working as instructor in scuba diving clubs were selected as research participants. The results are as follows. First, they perceived necessity of buddy selection through awareness of importance of buddy through education and through partner perception to overcome perceived danger. Second, when selecting a buddy, they established standards according to level whether they have a rescue diver license and secured standards through new sense of value. Third, buddy selection determinants were interaction between buddies, mutual trust and realization of buddy's role. As such, a SCUBA diver should select other buddy to perform pair diving and buddy is selected based on relationship such as mutual communication, mutual trust and belief. When they perform buddy's role comprehensively based on mutual relationship with buddy, continuous relationship as buddies can be built.
