Effects of Dragon Boating Intervention on Physical Function and Psychological Health of Breast Cancer Survivors

Exercise is important to counteract negative physical and emotional effects of breast cancer treatments. Dragon boating, a traditional sports event in China, has become a popular rehabilitation methods of breast cancer. This study examines effects of a dragon boating intervention on physical functioning and psychological health in breast cancer survivors. Breast cancer survivors (N = 40) were randomly assigned to an intervention (n = 20) or control group (n = 20). The intervention group participated in a dragon boating intervention twice a week over a period of 14 weeks, with each lasted for 75 minutes and at a rate of stroke \u3c 60t/min. The control group received no intervention. Patients from both groups were measured at during 1 and 14 weeks on levels of physical functioning (30s arm curls for upper limb strength, shoulder range of motion for upper limb flexibility, 30s sit to stand for lower limb strength, sit and reach for lower limb flexibility, 4m leg lifting for aerobic endurance, and arm circumference for body circumference) and psychological health including self-efficacy (measured by German General-Self-Efficacy Scale), stress (by Perceived Stress Questionnaire; PSQ20), and fear and depression (by Hospital Depression Scale). Comparing pre- to post- intervention data, significant improvements were found for the upper limb strength test (+7.15%; p = 0.023), upper limb flexibility (+ 11.6%; p = 0.008) and aerobic endurance (+9.25; p = 0.009) in the dragon boating group. No changes in patient-reported outcomes, lower limb function and body circumference were observed following the 14 weeks study period in both groups (p \u3e 0.05). Data analyses also showed a significant difference between both groups regarding the subscale joy (p = .018). Several significant results within the intervention group were seen in self-efficacy (p = .014), fear (p = .009) and the overall score for fear and depression (p = .043). Both groups improved significantly within worries (pintervention = .006, pcontrol = .019) and the PSQ20 overall score (both ps = .005). The control group also significantly improved in the subscale for demands (p = .019). Our study showed that dragon boating intervention yielded significant improvements in upper limb strength, flexibility, aerobic endurance, and mental health level but not lower limb physical fitness, body circumference, or quality of life. The dragon boating alone may not be considered as being comprehensively effective enough to help breast cancer survivors regarding relevant physical and psychological issues, but it might be an important supplement within follow-up care. Future efforts may explore the effect of dragon boating intervention with different intensities on rehabilitation effect

The purpose of this study was to explore the quality of community sports distribution service through the evaluation and satisfaction of the elderly in Yangpu District of Shanghai on the quality of community sports service and explore the relationship between the quality of community sports distribution service, satisfaction, and behavioral intention. Data were collected by using surveys and analyzed using mathematical statistics. The survey refers to SERVPERF model to design a six-dimension, intermediary variable satisfaction and behavioral intention five-point scale for the service quality of community sports distribution. The sample size was 261. SPSS25.0 was used to conduct data analysis. Reliability and validity test and correlation analysis of service quality and satisfaction and behavior intention of the elderly were conducted. The Cronbach\u27s Alpha value of the scale was 0.932. The KMO value was above 0.8, and Bartlett sphericity test was significant, indicating high reliability and validity of the scale. The analysis results showed that the mean values of the six dimensions of service quality and satisfaction were higher than 4.2, indicating that the elderly had a high evaluation of community sports distribution service quality. Community sports service delivery service quality dimensions and satisfaction and behavior intention between different degree of correlation, in addition to the tangibility of community sports service reliability of distribution service quality, responsiveness, assurance, empathy, and practicality for older people to participate in community sports service satisfaction and behavior intention of distribution had significant positive correlations. More women than men participated in community sports service delivery among the elderly since most of the delivery items are dance and martial arts. The elderly had a good participation in community sports service distribution, with the frequency and duration of weekly participation basically meeting the requirements of China\u27s sports population within 4-5 years. They had more than 30 minutes of moderate intensity training at least three times a week. According to the evaluation and satisfaction of the elderly on the service quality of community sports service delivery, community sports service delivery was of high service quality. The service quality of community sports service delivery had a positive impact on the sustainability of elderly people\u27s participation in community sports service delivery, and they were willing to recommend it to people around them to participate. Community sports service distribution activities should be publicized and promoted on the Internet so that more people can participate in the willingness

Effects of Soft Golf on Physical Fitness of Children Aged 4 to 5 Years

Playing golf is good for health. Previous studies found that golf training can improve performance such as muscle strength, endurance, balance, and agility. Constitution is the important foundation of national and social development, and children are the key period of constitution development. At present, there are few studies on the influence of golf on children\u27s physical fitness. This study explored the influence of 16-week soft golf exercise intervention on the physical health of 4–5-year-old children. Sixty children aged 4-5 years old were recruited from a kindergarten school in Shanghai, China with means of age at 4.56±0.54 and height at 112.72±3.96. Participants were randomly assigned into experimental group and control group. The physical fitness data were collected before and after the intervention. The intervention lasted 16 weeks of soft golf training with twice a week and 45 minutes each time. The control group did not do any training. The results showed that: (1) there were no significant differences between the experimental group and the control group in terms of lower limb strength and coordination ability. After intervention, Participants in the experimental group performed significantly better than those in the control group. (2) There were no significant differences in upper limb strength, endurance, and balance among participants between the experimental group and the control group. After intervention, Participants in the experimental group and the control group improved in physical fitness at varying degrees when compared with the pre-test, however the improvements were not statistically significant. This study showed that after 16 weeks of soft golf intervention, participants in the experimental group and the control group had different degrees of improvement in physical fitness test indicators. Especially in lower limb strength and coordination ability test indicators, participants in the experimental group performed significantly higher than those in the control group. It is suggested that the impact of soft golf on children\u27s physical fitness was positive. In China, research on golf and children\u27s physical fitness is still in its infancy. Soft golf retains the characteristics of traditional golf, and the development conditions are more convenient, which provide objective conditions for campus golf. The exercise effect of soft golf on physical fitness among different participants should be further explored in the future

In collaboration with researchers in Auto-ID Labs China, we have developed a service-oriented framework based on CA and Web Services, which supports inexpensive mediation of product information among rapidly evolving, heterogeneous information sources. Our architecture defines a user-driven security model that allows users to create entities and policy domains within virtual organizations. We emphasize that standard Web Services tools and software provide both stateless and stateful forms of secured communication

FINITE ELEMENT ANALYSIS OF THE SEISMIC BEHAVIOR OF THE ASSEMBLED LIGHT STEEL FRAME- LIGHT WALL STRUCTURES

In order to meet the needs of the development of low-rise assembly structure in rural areas, a fabricated light-weight steel frame-composite light wall structure is proposed in this paper. The light-weight steel frames are used to bear the vertical loads. The single-row-reinforced recycled concrete wall-boards are used as lateral members to resist most of the horizontal earthquake loads. The wall-board, EPS (Expanded Polystyrene) insulation modules, and fly ash blocks form the thermally insulated wall. Four fabricated lightweight steel frame-composite light wall structures and one light-weight steel frame (FRA) structure were tested under the low cyclic loads. The influence of wall reinforcement spacing and structural form (be it fly ash block or not) on the seismic performance of this new structure was analysed and the damage process of the specimen was simulated using the ABAQUS® software. The results show that the light steel frames and the single-row-reinforced recycled concrete wall-board can work well together. Furthermore, the structure has two clear seismic lines. Due to the use of EPS insulation modules and fly ash blocks, the structure has good anti-seismic and thermal insulation abilities. Reducing the spacing of bars or compositing fly ash blocks can significantly improve the seismic performance of the structure. The finite element method (FEM) calculations agreed well with the experimental results, which validates the proposed model
