Influencing Factors Related to Female Sports Participation Under the Implementation of Chinese Government Interventions: An Analysis Based on the China Family Panel Studies.

Objectives: Regular sports participation is a gendered phenomenon in China. Women have reported much higher constraints than men on time, partner, psychology, knowledge, and interest. This study explores personal, family, lifestyle, and health factors associated with sports participation. Study Design: This study is a cross-sectional study. Methods: Data were collected from the national reprehensive China Family Panel Studies (CFPS) database (2018) to analyze personal information, family background, lifestyle, and health in relation to women's sports participation. Multiple classification logistic regression was used to quantify the association between independent variables and sports time. Results: Women with high personal income and education, who were unmarried, in faster economic development areas have more awareness and more time for sports participation. Women who were overweight and self-rated as unattractive spent less time on sports participation. Women with a small family population and no children have more time for sports participation. Less time on the internet and moderate sleep contribute to active sports participation. Women with chronic diseases and high medical costs are less likely to participate in sports. Conclusions: Negative body aesthetic perception, the burden of family environment, modernization of lifestyle, and the normalization of sub-health are essential factors affecting women's sports participation. The government should understand the inner and outer barriers to women's participation in sports, develop policies and regulations to protect and support women's sports participation, and guide and monitor the effective implementation of women's sports activities.

[Influence of acupuncture on the motor ability in training-induced fatigue mice].

OBJECTIVE: To observe the influence of acupuncture on the motor ability of training-induced fatigue mice so as to explore its mechanism underlying acupuncture-induced improvement of physical training fatigue. METHODS: Sixty Kunming mice were divided into normal control, training model and acupuncture groups, with 20 mice in each. The training-fatigue model was established by forcing the mouse to swim in a water tank for 30 min/d in the 1st week, 60 min/d in the 2nd week, 90 min/d in the 3rd week and 120 min/d in the 4th and 5th weeks. "Guanyuan" (CV 4), and bilateral "Zusanli" (ST 36) and "Shenshu" (BL 23) were punctured with filiform needles, and with the needle twirled for about 30 s and retained for 5 min. Thetreatment was conducted once daily for 2 weeks. The duration of exhaustion training was recorded. Serum lactic acid (LA), lactate dehydrogenase (LDH) and creatine kinase (CK) contents were detected by LA oxidase method, immune-suppressive assay and enzyme-linked immunoassay, respectively. RESULTS: Compared with the training-fatigue (model) group, the duration of the exhausted swimming of the acupuncture group was obviously longer (P < 0.05). In comparison with the control group, serum LA, LDH and CK contents were increased considerably in the model and acupuncture groups (P < 0.05, P < 0.01), while compared with the model group, serum LDH level of acupuncture group was increased significantly (P < 0.05), and serum CK level of acupuncture group decreased obviously (P < 0.05). No significant difference was found between the model and acupuncture groups in serum LA content (P > 0.05). CONCLUSION: Acupuncture can effectively improve the motor ability of the training-fatigue mice, which may be closely relevant to its effects in upregulating LDH activity and reducing serum CK.
