Through a investigation of the physical activity status of 1794 undergraduates who were non-sports majors from freshman to senior in Jiangxi Normal University, to analyze physical fitness status of college students with different physical activity levels. The results showed that in physical activity, high-intensity physical activity of male was higher than female, while medium-intensity and low-intensity (insufficient) physical activity of female was higher than male. College students' high-intensity physical activity group's physical test scores were better than the medium-intensity physical activity group, and the medium-intensity physical activity group was superior to the low physical activity group. In terms of physical fitness, among the test indicators of body shape and physiological function, the vital capacity and body mass index of male and female were ranked at a pass level. In the physical fitness test indicators, the performance of college students' endurance qualities was better while the overall performance of strength qualities was lower. The overall fitness of college students was ranked at a pass level, and the physical test scores of female were better than male.

Purpose: The aim of this study was to investigate whether job satisfaction in clinical nurses was dependent on work intensity and whether physical discomfort mediated the relationships between these variables. Methods: Structural equation modeling was used with a sample of 253 clinical nurses from four general hospitals. In the model, absolute work intensity, relative work intensity, and flexibility were considered as exogenous variables and physical discomfort as a mediating variable. Data were collected using self-report measures such as the Labor Intensity Questionnaire, the Rating of Perceived Exertion, and the Index of Job Satisfaction. Results: The results of the structural equation modeling found that the higher scores on absolute and relative work intensity were positively associated with physical discomfort but only relative work intensity was significantly related to job satisfaction. Physical discomfort mediated the relationships between absolute work intensity and job satisfaction and between relative work intensity and job satisfaction. Among three kinds of work intensity, only relative work intensity had direct and indirect effects on job satisfaction. Conclusion: The findings suggest that increase in relative work intensity might play an important role in decreasing job satisfaction in clinical nurses and a reasonable reward system considering relative work intensity could be necessary.

The purpose of this study was to investigate the correlations between pain intensity, physical impairments, disability, and psychological factors according to the difference in duration of low back pain. This study was a cross-sectional survey of 102 participants with low back pain, divided into two groups equal in number: The first group consisted of patients with acute and subacute low back pain, while the second group consisted of patients suffering from chronic low back pain. The results showed that gender, age, pain intensity, physical impairment, disability and Fear-Avoidance Beliefs (FABs) for work activities were not significantly different between two groups. FABs for physical activities of the first group were significantly more prevalent than in the second group. More than moderate correlations were found between pain intensity, physical impairment, and disability in the first group. Less than moderate correlations were found between pain intensity, physical impairment, disability, FABs, and depression in the second group. These findings suggest that we must consider psychological factors in the treatment of patients with chronic low back pain. Regression analyses revealed that pain intensity and FABs for work activities significantly contributed to the prediction of disability in the first group. Also, pain intensity and FABs for physical activities significantly contributed to the prediction of disability in the second group. Pain intensity was most important predictor of disability in two groups.

Purpose: This study was conducted to determine if physical activity levels relieve the risk of development of metabolic syndrome (Mets) according to smoking intensity among smoking men. Methods: Secondary data from the 2010-2015 Korea National Health and Nutrition Examination Survey were used for this cross sectional study. A total of 3,027 men over the age of 19 were included for data analysis. Complex samples logistic regression was used to analyze the combined effects of smoking and physical activity on Mets. Smoking intensity was categorized as light (${\leq}20cigarettes/day$) or heavy (> 20 cigarettes/day), while physical activity was categorized as light (< 600 metabolic equivalent [MET]-min/week), moderate (600-3,000 MET-min/week), and vigorous (${\geq}3,000MET-min/week$). Results: Mets was less prevalent among light smokers with vigorous physical activity (Adjusted Odds Ratio [AOR]: 0.632, 95% Confidence Interval [CI]: 0.475-0.840) compared to those with light physical activity. Among heavy smokers, physical activity level was not significantly associated with Mets. Conclusion: Only vigorous physical activity exerted protective effects against development of Mets among low intensity smokers. For high intensity smokers, lowering smoking intensity and smoking cessation are also necessary to prevent development of Mets.

The purpose of this study was to investigate the effectiveness of the low-intensity ultrasound (noblelife) treatment on the pain points of upper trapezius muscle. The study recruited 20 patients who had trigger points in one side of the upper trapezius. The effectiveness of the low-intensity ultrasound treatment was assessed with subjective pain intensity using visual analog scale (VAS) and pressure pain threshold (PPT). The PPT was measured by pressure threshold algometer. Before and after the treatment, changes of pain were evaluated. Wilcoxon test for VAS data and paired t-test for PPT data were used for statistical significance. Compared to the pain intensity before the treatment, the pain intensity after treatment was significantly decreased (p<.05). Low-intensity ultrasound could be safely used in clinical application and at home for the treatment of patients with pain in upper trapezius muscle.

Psychsocial factors appear to play an important role in the maintenance and development of chronic disability from low back pain. Fear of pain may be more disabling than the pain itself in patients with nonacute low back pain. The purpose of this study was to identify the contribution of gender, age, depression and pain-related fear to pain intensity and disability in nonacute low back pain patients. This was a cross-sectional survey study of eighty four patients who had low back pain for at least 4 weeks. More than moderate correlations were found between pain intensity, disability, fear-avoidance beliefs and depression. Regression analyses revealed that disability ratings and fear-avoidance beliefs for work activities significantly contributed to the prediction of pain intensity, even when controlling for age, gender and pain duration. Also, fear-avoidance beliefs for physical activity, pain intensity, age and depression, significantly contributed to the prediction of disability, even when controlling for gender and pain duration. These findings suggest that disability scores and fear-avoidance beliefs for work activities are important determinants of pain intensity. They also suggest that fear-avoidance beliefs for physical activity, pain intensity, age and depression are important determinants of disability.

The purpose of this study was to investigate the changes of muscle power by transcutaneous electrical nerve stimulation(TBNS), low frequency-low intensity(20pps, invisible muscle contraction intensity), low frequency-high intensity(20pps, visible muscle contraction), high frequency-low intensity(100pps, invisible muscle contraction intensity) and high frequency-high intensity(100pps, visible muscle contraction). The results were as follows. 1. Increased muscle power after 30 minutes of treatment by low frequency-low intensity TENS, and post-treatment 30 minutes muscle power were increased more than pre-treatment power(p<0.05). 2. Decreased muscle power after a 30 minute treatment by low frequency-high intensity TENS, and after the 30 minute treatment was terminated muscle power didn't recover to pre-treatment levels. 3. Decreased muscle power after 30 minute treatment by high frequency-low intensity TENS, but post-treatment 30 minute, muscle power didn't recover to pre-treatment levels. 4. The muscle power was remarkably decreased by high frequency-high intensity TENS after 30 minute treatment, in addition treatment terminated after 30minutes didn,t recover to pre-treatment power(p<0.05). 5. Lower frequency-low intensity TENS are good methods for preventing muscle fatigue, buty high intensity (TENS) are increased muscle fatigue. 6. Traditional TENS by high frequency-low intensity is a good method for preventing muscle fatigue.

Background: Physical therapy applied to stroke patients is recognized as a treatment that promotes function recovery, and it is a widely known fact that constant exercise should be performed. However, there are insufficient studies on exercise intensity and exercise time that can minimize side effects and maximize function recovery for exercise therapy. Objectives: To determine the effect of exercise variables on CPK generation during aerobic exercise in stroke patients and to discover how to use appropriate exercise intensity and time when conducting an exercise for function recovery in stroke patients. Design: Quasi-experimental research. Methods: This study classified subjects into three groups (low-intensity exercise group: LIE, moderate-intensity exercise group: MIE and high-intensity exercise group: HIE) according to exercise intensity, and was further classified into two groups (10-minute exercise group: 10MG and 20-minute exercise group: 20MG) according to exercise time variables within each exercise intensity group. After, the change in CPK according to exercise intensity and time was confirmed through hematological analysis. Results: In LIE and MIE, the CPK blood concentrations before and after exercise were increased in 10MG and 20MG, which was not statistically significant (P>.05). In HIE, the CPK blood concentrations before and after exercise were increased in 10MG, and it was statistically significant (P<.05). In HIE, the CPK blood concentrations before and after exercise were increased in 20MG, and it was statistically significant (P<.01). In 10MG and 20MG, the CPK blood concentrations before and after exercises were increased in all intensity group, and there was a statistically significant difference only in HIE. Conclusion: From the results of this study, considering CPK, it will be helpful to recover and improve function if the exercise intensity setting is applied in the type of moderate intensity exercise during physical therapy interventions in stroke patients.

PURPOSE: The purpose of this study was to examine the effectiveness of a low-intensity combined exercise program on daily physical fitness parameters such as balance, flexibility, muscle strength, and fear of falling of elderly women in the community. METHODS: This study assigned 30 elderly women randomly into two groups: The control and experimental groups. The control group (n = 15) underwent routine gait. The experimental group (n = 15) underwent the low-intensity combined exercise. The exercise program in this study comprising combined exercise, including balance, flexibility, muscle strength training, and the exercise program using props was conducted twice a week for 8 weeks. RESULTS: The average age of the control and experimental groups was 77.27 years and 78.33 years, respectively. There were significant differences in static balance (t = -4.167, p < .001), dynamic balance (t = 2.463, p < .001), (t = -3.870, p < .001), (t = -2.262, p < .001), (t = -5.732, p < .001), (t = -6.573, p < .001), and fear of falling (t = -5.129, p < .001). CONCLUSION: The results show that low-intensity combined exercise is an effective intervention that improves physical health fear of falling in older women. The combined exercise program was found to be more effective in terms of physical function and fall-related psychological function compared to the control group that only walked.
