Background: Overweight, obesity, and cardiovascular disease risk factors are prevalent among firefighters in some developed countries. It is unclear whether physical activity and cardiopulmonary fitness reduce cardiovascular disease risk and the cardiovascular workload at work in firefighters. The present study investigated the relationship between leisure-time physical activity, cardiopulmonary fitness, cardiovascular disease risk factors, and cardiovascular workload at work in firefighters in Hong Kong. Methods: Male firefighters (n = 387) were randomly selected from serving firefighters in Hong Kong (n = 5,370) for the assessment of cardiovascular disease risk factors (obesity, hypertension, diabetes mellitus, dyslipidemia, smoking, known cardiovascular diseases). One-third (Target Group) were randomly selected for the assessment of off-duty leisure-time physical activity using the short version of the International Physical Activity Questionnaire. Maximal oxygen uptake was assessed, as well as cardiovascular workload using heart rate monitoring for each firefighter for four "normal" 24-hour working shifts and during real-situation simulated scenarios. Results: Overall, 33.9% of the firefighters had at least two cardiovascular disease risk factors. In the Target Group, firefighters who had higher leisure-time physical activity had a lower resting heart rate and a lower average working heart rate, and spent a smaller proportion of time working at a moderate-intensity cardiovascular workload. Firefighters who had moderate aerobic fitness and high leisure-time physical activity had a lower peak working heart rate during the mountain rescue scenario compared with firefighters who had low leisure-time physical activities. Conclusion: Leisure-time physical activity conferred significant benefits during job tasks of moderate cardiovascular workload in firefighters in Hong Kong.

Background: Physical inactivity has been identified as the fourth leading risk factor for global mortality and is associated with increased breast cancer diagnosis and recurrence. Purpose: To examine the association between adult lifetime physical activity and breast cancer risk in a case-control analysis. Materials and Methods: This study involved 122 cases of breast cancer and 121 controls in the state of Kelantan in Malaysia. A comprehensive measure of lifetime physical activity was used to assess occupational, household, and recreational/sports activity. For every type of activity, a metabolic equivalent (MET) score was assigned using the compendium of physical activities. MET-hours/week per year for all types of activities at different levels of intensities for different age groups were calculated. Logistic regression analysis was used to estimate odds ratios between various measures of physical activity and breast cancer risk. Conclusions: The mean MET-hours/week per year for all activities were 120.0 and 132.9 of MET-hours/week per year for cases and controls respectively. Household activities accounted for about 70% of the total lifetime physical activities. Only about 2.5% of the total lifetime physical activities were in the form of recreational/sports. This study found no association between lifetime occupational and recreational/sports physical activities with breast cancer risk among Kelantanese women. However, higher intensity lifetime household activities seemed to significantly reduce risk of breast cancer.

The purpose of the study was to identify available evidence related to physical activity interventions that were effective to improve health-related physical fitness levels of children and youth with disabilities. Studies were accumulated from multiple databases (i.e., ERIC, Child Development & Adolescent Studies, MEDLINE, SPORTDiscus with Full Text, and CINAHL Plus with Full Text). From the initial process, 1195 articles were identified and of those, 13 studies (n = 13) were analyzed. Based on the results, community-based physical activities were the most common environment of interventions followed by school-based and home-based. Further, the most improved health-related physical fitness outcomes were muscular strength, muscular endurance, and cardiorespiratory endurance while limited evidence on weight reduction was available. There is a need for more research on physical activity intervention which particularly improves health related physical fitness of children and youth with disabilities.

Background: Although physical activity is known to be beneficial to lung function, few studies have been conducted to investigate the correlation between physical activity and lung function in dusty areas. Therefore, the purpose of this study is to investigate the correlation between physical activity and lung function in a Korean cohort including normal and COPD-diagnosed participants. Methods: Data obtained from the COPD in dusty areas (CODA) cohort was analyzed for the following factors: lung function, symptoms, and information about physical activity. Information on physical activity was valuated using questionnaires, and participants were categorized into two groups: active and inactive. The evaluation of the mean lung function, modified Medical Research Council dyspnea grade scores, and COPD assessment test scores was done based on the participant physical activity using a general linear model after adjusting for age, sex, smoking status, pack-years, height, and weight. In addition, a stratification analysis was performed based on the smoking status and COPD. Results: Physical activity had a correlation with high forced expiratory volume in 1 second ($FEV_1$) among CODA cohort (p=0.03). While the active group exhibited significantly higher $FEV_1$ compared to one exhibited by the inactive group among past smokers (p=0.02), no such correlation existed among current smokers. There was no significant difference observed in lung function after it was stratified by COPD. Conclusion: This study established a positive correlation between regular physical activity in dusty areas and lung function in participants.

Objective : This study aim to identify the relationships among the types of physical activities included related included related work, sports, leisure, transport and sedentary behaviors and mental health in elderly person. Methods : We analyzed using the data of the 7th Korea National Health and Nutrition Examination Survey(KNHANES VII-1) of 978 subjects who underwent the types of physical activities, quality of life, depression, level of stress, and sleeping hours survey. For statistical analysis, the Complex samples linear regression was used for relationships among the variables. Results : High level of physical activity and house-keeping activity associated negatively on health related quality of life. Mid-High level of leisure activities associated positively on health related quality of life. Contrasting from other studies, which show sedentary activities associated negatively on the health related quality of life, and sedentary activities associated positively on the health related quality of life and mental health. Conclusion : This study shows that physical and leisure activity of an elderly person whilst sedentary activities related positively on health related quality of life, and physical activities related to labor associated negatively on health related quality of life. Future studies should be referred when planning an occupation-focused and meaningful activity program for the elderly people.

The purpose of this study was to examine the effects of physical activity on women's health. I conducted literature reviews for meta-analyses and randomized controlled trials with the target diseases including cardiovascular diseases, diabetes, cancers osteoporosis, and pregnancy outcomes. Women who were active had less total mortality and smaller incidence of hypertension, coronary heart diseases, and stroke. Exercise was better than drug therapies in preventing diabetes and effective in preventing colon and breast cancers. Exercise can reduce the risks of falling injury in elderly women. Walking during pregnancy was not harmful to the mothers and their infants, and desirable to prevent the complications of pregnancy or weight gain after pregnancy. Physical activity at work and leisure-time showed similar effects on women's health. Based on these results, moderate-intensity physical activity should be recommended to all women, Resistive, muscle strength, and balance-training exercise also can be recommended. Doctors' advices are effective to make women exercise, especially using handouts or motivational interviewing techniques. It is desirable to recommend to peform other health promotion measures together such as smoking cessation, weight control and diet control.

Purpose: This study was done to assess the level of physical activity among Chinese immigrant women and to determine the relationships of physical activity with individual characteristics and behavior-specific cognition. Methods: A cross-sectional descriptive study was conducted with 161 Chinese immigrant women living in Busan. A health promotion model of physical activity adapted from Pender's Health Promotion Model was used. Self-administered questionnaires were used to collect data during the period from September 25 to November 20, 2012. Using SPSS 18.0 program, descriptive statistics, t-test, analysis of variance, correlation analysis, and multiple regression analysis were done. Results: The average level of physical activity of the Chinese immigrant women was $1,050.06{\pm}686.47$ MET-min/week and the minimum activity among types of physical activity was most dominant (59.6%). As a result of multiple regression analysis, it was confirmed that self-efficacy and acculturation were statistically significant variables in the model (p<.001), with an explanatory power of 23.7%. Conclusion: The results indicate that the development and application of intervention strategies to increase acculturation and self-efficacy for immigrant women will aid in increasing the physical activity in Chinese immigrant women.
