  • The purpose of this study is to examine the impacts of neighborhood sports activity facilities on the exercise time and subjective health level using the National Sport Participation Survey data(2013-2015) in Seoul, Korea. We conducted path analysis including exercise time, subjective health level and various environmental factors. From the survey data, we extracted individual's characteristics including subjective health and exercise time. In addition, we calculated physical environment variables of neighborhood units. The results of this study are as follow. First, most of moderating variables such as gender, age, income and job showed expected relationships with exercise time or subjective health level. Second, the perceived level regarding neighborhood sports facilities such as public sports facilities had a strong positive association with exercise time and subjective health level. Third, the area of public sports facility, neighborhood park and the number of schools had positive effects on the exercise time and subjective health level. Lastly, land use mix and the number of intersections showed a positive effects on exercise time. To sum up, the results indicated that public sports facility, neighborhood park and perceived environment on neighborhood sports facility are critical factors of residents' exercise time and subjective health level.

  • Purpose: The purpose of this study was to investigate the effect of exercise therapy and relaxation therapy on the level of ACTH and cortisol in workers and to determine, from this information, the effectiveness of applied exercise therapy and relaxation therapy as a nursing intervention method for workers experiencing stress. Method: The subjects were divided into an exercise therapy group. a relaxation therapy group, and a control group. The research design was a nonequivalent control group pretest-posttest design (exercise therapy : n=12. relaxation therapy: n=12, control group, the group without exercise or relaxation therapy: n= 12). The subjects in the exercise therapy group were given a particular intensity for each kp over 30 min, bicycle ergometer which uses the LX PE training system before and after four weeks of training. The subjects did 60-70% exercise intensity exercise therapy for eight weeks The relaxation therapy subjects were trained using a modified Jacobson's relaxation technique for eight weeks. The exercise and relaxation therapy groups were trained at the following intensity for eight weeks (3 times/week, 30 min/day). Changes in the levels of ACTH and cortisol were identified. Two-way ANOVA and multiple range test (SNK: Student Newman Keul) were used to examine the effects of exercise therapy and relaxation therapy at four and eight weeks. Result: 1. Changes in the level of ACTH in the relaxation therapy group were statistically significant at .05 level, and were better than that of the exercise therapy group after eight weeks. But there was no significant difference between the exercise therapy group and the control group. 2. Change in the level of cortisol in the relaxation therapy group were statistically significant at .05 level as compared to the exercise therapy group and the control group after four weeks, but not after eight weeks. Also, the relaxation therapy was statistically significant at .05 level after four weeks compared to before treatment, but there was a tendency toward increased cortisol after eight weeks. Conclusion: Relaxation therapy was found to be more effective in stress treatment than exercise therapy and as such is a desirable nursing intervention method for stress hormone reduction in workers.

  • The purposes of this study are to identify the degree of exercise intent and behavior and to determine factors influencing exercise and behavior in middle school students. The subjects for this study were 658 middle school students in Chonbuk area. The data were obtained by questionaire for the period from Nov. 1 to Dec. 20, 1990. The instrument used for the study were included 6 existing scales and 2 scales developed by the researcher for this study. They are: 1) The exercise intent scale to assess the exercise plan even when they had no longer physical education. 2) The current exercise behavior to measure of exercise frequency for 1 week. 3) The scale to measure the level of self -esteem. 4) The scale to measure the level of knowledge about exercise. 5) The scale to measure the level of the perceived ability to make commitment. 6) The scale to measure the level of the perceived benifit of exercise. 7) The scale to measure the level of the perceived athletic ability. 8) The scale to measure the level of the attitude toward physical education. The data were analyzed using frequency, percentage, one way ANOVA, Pearson Coeffecients Correlation and stepwise multiple regression. The following; results were obtained. 1. Exercise intent level was in the intermediate range(mean on five point scale of 3.66, with 1 = definitely no). 2. The current exercise behavior level was relatively low(mean=1.77, with l=less than once per week and 4 = 4 or more times per week). 3. Self -esteem levels were in the intermediate range(mean on five point scale of 2.96, a mean of 5.0 indicate highest level of self-esteem.) 4. The levels of perceived ability to make commitments were in the intermediate range(mean=3.05, with 5.0 as most able). 5. The levels of perceived exercise as benificial were relatively high(mean=3.72, with 5.0 as most benificial). 6. Knowledge levels about exercise were realatively high(mean=3.97, with 5.0 as most knowledgeable). 7. The levels of perceived athletic ability were in intermediate range(mean=3.01, with 5.0 as highest score). 8. The levels of attitudes toward physical education were in the intermediate range(mean=3.29, with 5.0 as most favorable). 9. Among the general characteristic variables, sex, interest sports activities were related to the difference of exercise intent levels. 10. Of the predictor variables analyzed, self - esteem, perceived benifit of exercise, perceived athletic ability, knowledge about exercise and attitude about physical education correlated significantly and positively with exercise intent. Correlations of predictors with current exercise behavior were similiar to exercise intent, exept knowledge about exercise. 11. The stepwise multiple regression analysis shows findings as follows: 1) The most important factor to explain the difference of exercise intent was current exercise behavior. 2) The most improtant factor to explain the difference of current exercise behavior was perceived athletic ability.

  • PURPOSE: This study examined the changes in the blood fatigue variables caused by isokinetic and isotonic exercise training. METHODS: Ten healthy adult males with at least one year of athletic experience participated. The participants performed the isokinetic circuit exercise program first, followed by an isotonic circuit exercise program. A two-hour break was allowed between the isokinetic circuit exercise program and the isotonic circuit exercise program. The circuit exercise program consisted of four items (Squat, Deadlift, Shoulder press, and Bench press). The blood samples were analyzed for the LDH, CPK, and Cortisol levels. RESULTS: The LDH level in the isokinetic group was significantly different from the isotonic group. In particular, the change in LDH level in the isokinetic group was 33.30% lower than that of the isotonic group. The serum CPK level of the isokinetic group showed a 10.03% lower decrease than the isotonic group, but the difference was not significant. The Cortisol level was relatively unchanged in the isotonic group, but it decreased in the isokinetic group. On the other hand, the Cortisol level did not show a significant difference between the two groups. CONCLUSION: The isokinetic group showed alleviation of the three indices, unlike the isotonic group. Further studies associated with the changes in blood fatigue variables through various exercise programs and exercise intensity will be needed.

  • Purpose: This study aimed to construct and test a hypothetical model to explain the predictive factors and causal pathways for exercise levels in patients with ankylosing spondylitis based on the self-determination theory. A conceptual framework was constructed assuming that autonomy support by health care providers would satisfy the three basic psychological needs of patients, which would increase their autonomous motivation for exercise, resulting in its initiation and continuation. Methods: This cross-sectional study included 221 patients with ankylosing spondylitis who were visiting rheumatology clinics in two tertiary hospitals. Health Care Climate Questionnaire-exercise regularly, Basic Psychological Needs Satisfaction scale, Behavior Regulation in Exercise Questionnaire-2, and exercise level were used to collect data. Results: The fitness of the hypothetical model met the recommended level (𝛘2/df ≤ 3, SRMR ≤ .08, RMSEA ≤ .08, GFI ≥ .90, AGFI ≥ .85, NFI ≥ .90, TLI ≥ .90, CFI ≥ .90). The model effect analysis revealed that autonomy support by health care providers had a positive effect on patients' autonomy, competence, relatedness, autonomous motivation, and exercise level. Competence and relatedness had positive effects on autonomous motivation and exercise level, respectively. Autonomous motivation had a positive effect on exercise level. Conclusion: The predictive factors of exercise level in patients with ankylosing spondylitis were autonomous motivation, health care providers' autonomy support, competence, and relatedness. Considering these factors, we recommend the development of an effective program for improving exercise levels in these patients.

  • This study investigates the exercise-physiological changes in stages through the movement of the automatic stepper and to analyze the usefulness of the automatic stepper. For 18 male university students, out of 10 levels, 5 level and 10 level of automatic stepper exercise were performed. At each 10, 20, 30 minutes during exercise, 5 and 10 minutes after exercise stop the subjects were examined to analyze the changes in energy consumption after minutes, respiratory exchange rate, heart rate, oxygen consumption per body weight, METs, cumulative energy consumption, and lactic acid to verify the usefulness of the automatic stepper. The mean and standard deviation were calculated using the SPSS, and one-way ANOVA with repeated measure was performed to verify the difference in the mean between time periods. The LSD method was used for the post-hoc test, and the significance level was set to α = .05. There were no significant changes in both 5 and 10 level, but the cumulative energy consumption over time increased significantly. In addition, as a low-intensity exercise intensity is shown, a low increase in lactic acid indicated a safe exercise level. In future studies, in-depth studies of various variables through regular exercise programs are needed for those who need safe exercise.

  • We investigated the exercise-induced changes in the serum concentration of several minerals in horses. Four welltrained Thoroughbred horses performed exercise for 5 d. The blood hemoglobin (Hb) concentration increased during exercise, recovered to the pre-exercise level immediately after cooling down and did not change again up till the end of experiment. The changes in serum zinc (Zn) and copper (Cu) concentrations were similar to those of blood Hb during the experiment. The serum magnesium (Mg), inorganic phosphorus (Pi) and iron (Fe) concentrations also increased during exercise. Though the serum Pi concentration recovered to the pre-exercise level immediately after the cooling down, it decreased further before the end of the experiment. The serum Mg concentration was lower immediately after cooling down than its pre-exercise level but gradually recovered from the temporal reduction. The recovery of the serum Fe concentration was delayed compared to that of other minerals and recovered 2 h after cooling down. The serum calcium (Ca) concentration did not change during exercise but rapidly decreased after cooling down. As a result, it was lower immediately after cooling down than its pre-exercise level. It recovered, however, to the pre-exercise level 2 h after cooling down. The temporal increase in the serum concentrations of all minerals except Ca is considered to result from hemoconcentration induced by exercise and the stable concentration of the serum Ca during exercise is possibly due to its strict regulation of homeostasis. These results indicate that the serum concentration of each mineral responds differently to exercise in horses, which may be due to the difference in metabolism among these minerals.

  • BACKGROUND/OBJECTIVES: Successful recovery of an animal from exercise is essential, especially prior to the next exercise session. This study was conducted to find an effective exercise-to-rest period ratio for the restoration of energy sources and replenishment of anti-oxidative status in tissue after exercise. MATERIALS/METHODS: Thirty-two rats were assigned to either non-training or training exercise groups for 5 weeks. After that period, the two groups were subdivided into four smaller groups: non-exercise (NE), exercise 0.5 hour and rest 1 hour (ER0.5:1), exercise 1 hour and rest 1 hour (ER1:1), exercise 2 hours and rest 1 hour (ER2:1). RESULTS: In the training group animals and compared to the NE group, the levels of plasma glucose after the rest period were significantly high in all ER groups but highest in the ER2:1 group. Similarly, the liver glycogen level was highest in the ER2:1 group. The plasma FFA level reached the highest level in the ER2:1 group but was similarly high in the ER0.5:1 group. Liver TG level was unchanged in the ER2:1 and ER1:1 groups but was significantly high in the ER0.5:1 group. Muscle TG levels were decreased in all three ER groups. Plasma protein levels were significantly high in the ER2:1 and ER0.5:1 groups. In both training animal and non-training animals, the liver protein levels did not change significantly between the NE and ER groups, irrespective of the exercise-to-rest ratio. In the training animal group, muscle protein level was significantly low in the ER2:1 and ER0.5:1 groups. The activity levels of superoxide dismutase and catalase, as well as the malondialdehyde concentration, were not significantly different between NE and ER groups, irrespective of the exercise-to-rest period ratio. CONCLUSIONS: These results indicate that animals provided with a 0.5:1 to 1:1 exercise-to-rest period ratio can restore their muscle energy sources and recover their anti-oxidative defense system.

  • The purpose of this study is to analyze the effects of exercise therapy on serum lipid levels and antioxidants of obese and normal college female students. The subject group composed of ten normal-weight students(below 30% body fat ratio) and ten obese students(above 30% body fat ratio). After a pilot test, the subjects were given an eight-weeks exercise program. Before and after the exercise program, the subjects were given test for serum lipid and antioxidants were analyzed. The SAS program was used in the data analysis. The statistical measurements employed here were T-test, Wilcoxon signed rank test, and Wilcoxon rank sum test. The results of this research are as follows. 1) The effects of exercise therapy on serum lipid levels : Before the exercise therapy, the levels of Total-cholesterol, Triglyceride and LDL-cholesterol of the obese group were highier than those of the normal-weight group. However, the HDL-cholesterol levels were highier in the normal-weight group than in the obese group, but these differences were not significant. With the exercise therapy, the levels of Total-cholesterol increased gradually. The HDL-cholesterol increased gradually, the LDL-cholesterol level decreased in both groups, However, the Triglyceride level decreased in the obese group and increased in normal group, but the difference was not significant. 2) The effects of the exercise therapy on serum antioxidants ; Before exercise therapy, the serum FR and GSSG levels of the obese group were significantly highier than those of the normal-weight group(p=0.00, p=0.04). The serum GSH level of the normal-weight group was highier than that of the obese group, and the serum MDA level of the obese group was highier than that of the normal-weight group. Again these differences were not significant. With exercise therapy, serum FR level was reduced and serum GSSG level significantly increased in both group(obese group p=0.01, normal-weight group p=0.01), The serum GSH level of the obese group significantly increased (p=0.01), and serum MDA level significantly increased in the obese group(p=0.01), but the difference in the normal-weight group was not significant. These results show that regular exercise therapy reduces serum FR levels and activation of antioxidant systems, and suppress oxidative stress. These effects were slightly highier in the obese group than in the normal-weight group. The regular exercise therapy decreased the serum Triglyceride levels more in the obese group than in the normal-weight group. However the improvement of the serum lipid profile may require a longer exercise period than eight weeks. The results show that the exercise therapy was overall more effective in the obese group than the normal-weight group.
