PURPOSE: The purpose of this study is to compare the effects of aerobic exercise and combination exercise on physical fitness, body composition, and depression and to observe the relationship between obesity and depression. METHODS: A total of 40 obese people were divided into an aerobic exercise group ($n_1$=20) and a combination exercise group ($n_2$=20) that was performed swiss ball exercise and aerobic exercise. Each group exercised three times per week for eight weeks. Outcome measures were basic physical fitness, body composition, and depression. RESULTS: After completion of the exercise, there was a significant difference in overall physical fitness factors of percentage body fat (%body fat), strength, muscle endurance, flexibility, cardiovascular endurance in the combination exercise group (p<.05). Strength, muscle endurance, flexibility, and cardiovascular endurance were more improved in the combination exercise group than aerobic exercise group (p<.05). However, changes of %body fat and psychological factor between the two groups were not significant. CONCLUSION: Combination exercise program has an effect on the solution of obesity in physical development and strength. Therefore, it seems to that use with better perform both aerobic exercise and Swiss ball exercise. In addition, the Swiss ball exercise, which is an easy, convenient and economical self-exercise that can be done at home, is recommended due to its positive effects on physical establishment and fitness.

Background: Recommendations have been proposed for minimum aerobic fitness among firefighters but it is unclear if those criteria relate to performance on the fireground. Less fit individuals fatigue more quickly than fit individuals when working at comparable intensity and may have gait changes, increasing risk of falls. We evaluated the effect of fatigue during a live burn evolution on gait parameters and functional balance comparing them to aerobic fitness levels. Methods: A total of 24 firefighters had gait and balance tested before and after a live burn evolution. Data were stratified by aerobic fitness of greater/less than 14 metabolic equivalents (METs). Results: Analysis of gait cycles measurements before and after the live burn evolution revealed that single leg stance, cycle, and swing time decreased (p < 0.05) but there were no differences in the other measures. There were no differences in time to complete the functional balance test, or errors committed before or after a live burn evolution. When firefighters were sorted by fitness level of 14 METs, there were no differences for errors or time before or after the live burn evolution. Balance data were analyzed using a linear regression. Individuals with lower fitness levels required more time to complete the test. Conclusion: A 14-MET criterion failed to distinguish gait or balance characteristics in this group. However, less fit firefighters did require more time to complete the balance test (p = 0.003). Aerobic fitness alone does not predict gait changes among firefighters following a live burn evolution but does appear to influence functional balance.

This study was performed to investigate the correlations among physical anthropometric measurement, diet intakes, physical fitness test, and serum lipids in eight sedentary women(control group), and twenty seven exercising women(aerobic groups), aged 35~45 years. The results of the study are as follows : 1) systolic blood pressure(SBP) and diastolic blood pressure(DBP) of aerobic groups were lower than serf entary. Pulse rate was decreased according to the length of aerobic periods. Muscular endurance and jump power of all subjects were stronger than standard range, and those of aerobic exercising groups were stronger than control group. Muscular power of the upper half of the body In all subjects were lower than standard range. 2) Daily calorie intakes of all subjects were in the ring: of recommended dietary allowances (RDA) for Koreans. But daily protein Intakes were higher than RDA. daily cholestrol intakes of all subjects were slightly less than 200~300 mg: which is normal consumption of Koreans. 3) There was a significant positive correlation between serum 7G and daily protein intakes. It was considered that excessive protein intake converted to serum 7G. There was not a significant correlation between serum TC and dietary TC. Therefore, dietary TC seemed to have not much effect on serum TC. Physical fitness was negatively related to serum TG, TC, LDL-C, but positively related to HDL-C, HDL-C /TC. It was found that the serum lipids could be changed better according to improving the physical fitness. There were significant positive correlations between SBP and serum TC, LDL-C. (According to this results), the higher SBP, the higher serum TC, LDL-C tended to be. There was a significant positive correlations between sit up and weightloss nth exercise r=0.7(p<0.001), push ups and weightless with exercise r=0.5(p<0.001). It was considered that muscle strength could be improved according to the weightloss. 4) The purpose of exercise in aerobic groups was rather promoting health than reducing body fatness. Most of al1 subjects (83.2%) drank caffeine-contained beverage therefore, we should concern about that absorption of Fe could be Interrupted and blood pressure could be elevated by caffeine.

This study was performed to evaluate the effect of placebo(emotional stimulus) on physical fitness and psychological wellbeing. The subjects for the study were devided into two groups. One experimental group received placebo and the other control group did not receive. Each group was composed of 15 women. The subjects continued aerobic exercise for an hour each time, three times a week, for eight weeks. The enhancement of physical fitness has been evaluated by body weight, BP, pulse rate, skinfold thickness, circumference of waist and hip, body fat, % body fat, lean body mass, % lean body mass they were measured three times every 4 weeks. Also to evaluate the enhancement of psychological wellbeing, the self-esteem and self-perception were measured. The results can be summarized as follows : 1. The % body fat of experimental group decreased significantly than that of control group(p<0.1). 2. The % lean body mass of experimental group decreased significantly than that of control group(p<0.1). 3. There was no significant difference of other physical fitness factors between experimental group and control group. 4. There was no significant difference of self-esteem between experimental group and control group. 5. There was no significant difference of self-perception between experimental group and control group. From these results, it may be concluded that placebo(emotional stimulus) which received during aerobic exercise period is partially effective in the enhancement of the physical fitness.

Objectives: The purpose of this study was to examine the effect of smoking on aerobic physical fitness among physical education major male university students participating in regular exercise. Methods: A group of 42 healthy male students majoring physical education were divided into two groups: non-smokers (n=$26, 20.61{\pm}2.78 $yrs) and smokers (n=16, $21.25{\pm}2.29 $ yrs). Graded exercise testing for maximal oxygen consumption ($VO_2max$) was measured by Bruce protocol. Results: $VO_2max$ was not different between non-smokers and smokers, however, exercise duration time in non-smokers was more longer than smokers'. In non-smokers, ventilatory threshold (VT) time was delayed longer than smokers (p<0.01). %VT/VEmax was significantly different between non-smokers and smokers (p<0.01). Resting heart rate (p<0.01) and recovery heart rate at 80 seconds (p<0.01) in non-smokers were significantly lower than those of smokers. The decrease in heart rate recovery in non smokers was greater than in smokers at 40(p<0.05), 60(p<0.05) and 80(p<0.01) seconds. Conclusions: These results suggest that smoking has negative effects on aerobic fitness of male university students in physical education major.

The purpose of this study was to compare the anaerobic threshold (AT) between subjects with and without non-specific chronic low back pain (NCLBP). The patient group included 15 women with NCLBP. The normal group included 15 women without NCLBP who were age-, height-, weight-, and activity level-matched. The subjects performed a Balke treadmill protocol which was symptom-limited progressive loading test. Their heart rate (HR), ventilatory gas and metabolic equivalents (METs) were measured using the automatic breath gas analyzing system. After the test, each subjects' ratings of perceived exertion (RPE) were evaluated. The visual analog scale (VAS) was assessed pre- and post-test. The independent t-test and Wilcoxon's signed-rank test were used for analysis of the data. Time, HR, the volume of oxygen consumption ($VO_2$), relative $VO_2$, and METs at the AT level of the patient group were significantly lower than those of the healthy group (p<.05). However, there were no significant differences in RPE, VAS, and breathing frequency at the AT level (p>.05). The findings of this study indicate that patients with NCLBP had a lower aerobic fitness than healthy subjects. Thus, implementation of rehabilitation program to increase aerobic fitness may be considered in patietns with NCLBP, and further studies are required to determine the etiological factors of decreased aerobic fitness.
