| Objective: In this study, "outdoor manual worker," the special population study. Their incidence of sub-health, characteristics and influencing factors were investigated. And aerobic exercise training on them, Discussion on the positive role of aerobic exercise of its sub-health state. Improve social awareness of outdoor manual workers. Methods: Use Random sampling method to survey drivers, construction workers, security guards, couriers four occupations outdoor manual workers, a total of 1032. Questionnaire, statistics and test method for outdoor physical sub-health status of the investigation and Exercise. Before and after exercise body shape detection subjects(BMI, waist and hip circumferences), athletic qualities(reaction speed, balance capacity, Flexibility, explosive force, muscle power), physical function(spirometry, blood pressure, heart rate) and blood lipid levels(TC、TG、HDL、LDL), changes in these indicators before and after comparison exercise. Using SPSS19.0 statistical software for statistical processing of all data. Result:(1) survey results: 1032 survey, the number of sub-health occurred as 631 people, the occurrence ratio of 61.1%, a higher proportion occurred. Men who have a ratio of 60.8%, women 63.4%, higher in women than men; All ages sub-health different proportions, in which men had the highest proportion in the 56-60 years old 75%; The highest proportion of women occurred in the 36-45 years of age, was 68.6%; Four occupations, driver sub-health ratio of 71.4%, 57.3% of construction workers, couriers 53.8%, 60.5% of security guards; Binary logistic regression statistics showed that gender, length of service, age, drinking, "the health benefits of exercise degree of recognition" is an important factor in the occurrence of sub-health.(2) the results of aerobic exercise: Compared with the previous motion, power, lung capacity and blood pressure has a very significant difference(P <0.01), LDL significant difference(P <0.05), the other indexes are improved compared with that before the movement, but not statistically significant. Conclusion:(1) Outdoor manual worker’s health is not optimistic, belong to a high incidence of sub-health population, with women more than men, women, youth stage is higher than other age groups, the characteristics of male senile phase is higher than other phases.(2) the proportion of sub-health in different occupations are not the same, in descending order for drivers, security guards, construction workers, couriers.(3) Sex, length of service, marriage, education, Drink, monthly income, frequency of drinking, exercise frequency is an important factor for outdoor manual worker occurred sub-health.(4) Aerobic exercise a certain intensity of manual worker outdoors sub-health body shape, quality, function and blood lipid levels can have a positive impact. Especially in lower extremity muscle strength, improve heart and lung function and blood lipid levels of the most significant.(5) Outdoor manual worker, although mainly in manual labor, but the manual is not the same sport. Having passive physical limitations, high strength, long cycle and so on, could easily lead to fatigue, injury, and even disease. Therefore, these groups should also actively participate in physical exercise. And it recommended that the relevant units and the community should strengthen the focus on this group, to take active measures to improve their health, so they can better play the effectiveness of labor in urban construction and social service work. |
