Comparison of Cultural Interaction with Summer Olympic Games and Winter Olympic Games SUN Baoli, SUN Baojie, XU Ziqi 2019, 45 (3):  1-6.  doi: 10.15942/j.jcsu.2019.03.001 Abstract ( 1852 )   PDF (2031KB) ( 831 )   Save Using literature method, this present paper compares cultural interaction with Summer Olympic Games and Winter Olympic Games form the perspective of cultural structure. The results show that: The Olympic movement is a social and cultural phenomenon. Therefore, both Summer Olympic Games and Winter Olympic Games will inevitably interact with culture. The interaction mainly occurs on the three levels of material culture, organizational culture and spiritual culture. On the one hand, Summer Olympic Games and Winter Olympic Games are of the same origin. Therefore, they are similar in their interaction with culture. On the other hand, Summer Olympic Games absorbs the essence of modern sports, presenting a global characteristic in culture. In comparison, Winter Olympic Games has an obvious regional characteristic in culture, and its interaction with culture has its own unique characteristics. This is where the cultural interaction with Summer Olympic Games and Winter Olympic Games differ from each other. Related Articles | Metrics

From Enaction to Emersion: A body perception by awareness of living body Bernard Andrieu 2019, 45 (3):  7-16.  doi: 10.15942/j.jcsu.2019.03.002 Abstract ( 1529 )   PDF (1351KB) ( 689 )   Save Body perception has analysed by motor activity. This is largely the result of Le Boulch's work on psychokinetics and psychomotor education, which made new levels available for the description of body schema activity beyond that of conscious movements. Reflex movements, involuntary gestures, and emotions are all evidence of the pre-attentional activation and preparation for motor actions. Body perception is built from the interaction between the body and the world. With this in mind, we would like to draw attention to the current paradoxical gap in the literature that exists between the living and the perceived body. We then propose a means of overcoming this gap through a description of the activation of the living body and its emersion at the level of perception. Enaction, in Francisco Varela’s groundbreaking work, explains how neurodynamics bring emergences from our living body to our consciousness by awakening and activating our potential capacities. In this sense enaction is a neurodynamics, while emersion ensures the bottom-up transition of implicit information from the living body (Leib) to consciousness and to the attentive perception of the lived body (Korper).

The Essence of Sports from thePerspective of Humaneness GU Shanguang, ZHOU Xuerong 2019, 45 (3):  17-22.  doi: 10.15942/j.jcsu.2019.03.003 Abstract ( 1715 )   PDF (1202KB) ( 874 )   Save Human and body are the core elements of sports existence. The relationship between human and body's sports value is the root of sports value. The nature of sports depends on the human before the body or the nature of human for human nature is the basic reference standard of value and moral judgment. According to Sartre's philosophical view of "existence precedes essence"and Heidegger's humanistic view of "existence ontology", only when human has a nature which is in line with its body and takes such human nature as the normative basis for the existence of sports essence can they ensure the existence of human before the body and the rationality and moral legitimacy of sports in reshaping the body. Under the humanistic perspective of harmony between human and body, the essence of sports is the naturalization of body. Related Articles | Metrics

Effects of Hypoxic Exercise on the Hypoxia of Adipose Tissue in Rats with Insulin Resistance CHEN Shengju, SHANG Huayu, BAI Shengchao, ZHANG He, ZHANG Junfen, QIU Pingxue, ZHOU Yue 2019, 45 (3):  69-74.  doi: 10.15942/j.jcsu.2019.03.011 Abstract ( 1520 )   PDF (3216KB) ( 684 )   Save Objective: To explore the changes of a series of indexes of adipose tissue in hypoxic exercise in a high-fat diet (HFD) induced insulin resistance rats model, and preliminarily investigate the effects of hypoxia on adipose tissue in rats with insulin resistance, so as to provide a new theoretical basis for exercise treatment of obesity and insulin resistance. Methods: The rats were screened by a HFD for 8 weeks and a model of insulin resistance was established. The 24 rats were randomly divided into 4 groups: control group (NC, n=6), normoxic exercise group (NE), hypoxic quiet group (HC, n=6) and hypoxic exercise group (HE, n=6). The rats in NE and HE were trained by the horizontal animal running platform, and the rats in HC and HE were treated with 13.7% oxygen concentration, and the rats were weighted in the next day during the test period. After the experiment, the rats were killed. Their perirenal and epididymal adipose tissue were stripped and weighted. The changes of adipocyte diameter were observed by HE staining. Western blot detected the protein expression of HIF-1α and Glut-1 in adipose tissue. Results: 4-week hypoxic and exercise can significantly reduce the weight and increase of rats (P＜0.05). The total fat content of the rats in exercise groups was significantly lower than that of other groups (P＜0.05), while showed no significant difference between the two exercise groups (P＞0.05). The adipocyte diameter in each group was significantly lower than that in the control group (P＜0.05). Exercise and hypoxia can significantly reduce the expression of HIF-1α in adipose tissue (P＜0.05), which has no significant effect on the protein expression of Glut-1 (P＞0.05). Conclusion: From the perspective of slowing down the body weight gain and fat content, the effect of weight loss in normoxic exercise and hypoxic exercise are better than that of pure hypoxic exposure. Both hypoxia and exercise can significantly improve the status of anoxia in adipose tissue, but have no obvious effect on glucose metabolism. Normoxic exercise is more beneficial to improve the anoxia of adipose tissue in individuals with insulin resistance. Related Articles | Metrics

Methods: Sixty participants were randomly divided into four groups: health control group, health Wuqinxi group, metabolic syndrome control group and metabolic syndrome Wuqinxi group. Health control group and metabolic syndrome control group remained their normal lifestyle and no intervention was applied, whereas health Wuqinxi group and metabolic syndrome Wuqinxi group received Wuqinxi interventional training for 6 months. Intestinal flora, lipopolysaccharide, short-chain fatty acid, glucagon-like peptide-1, glucagon-like peptide-2, fasting blood glucose, fasting insulin, insulin resistance index of participants from four groups were assessed at four time points: one day before, two-, four-, and six-month after Wuqinxi interventional training. Results: The quantities of bifidobacteria, lactobacilli, bifidobacteria/scherichia coli and bacteria producing short-chain fatty acid were significantly decreased, and they were negatively correlated with insulin resistance index. The quantities of escherichia coli, staphylococcus and lipopolysaccharide were significantly increased, and they were positively correlated with insulin resistance index. The intestinal flora and its metabolites of middle-aged men who were healthy or patients with metabolic syndrome could be significantly optimized and the time-dose effect was also evident after Wuqinxi interventional training. Conclusion: It may be an important microbiological mechanism for improving middle-aged men's metabolic syndrome that the intestinal flora, lipopolysaccharide, short-chain fatty acid, glucagon-like peptide-1 and glucagon-like peptide-2 could be optimized after Wuqinxi interventional training.

Research on the FMS and YBT and the incidenceof sports injuries in Chinese elitemilitary pentathlon athletes TANG Qiao, ZHANG Haizhong 2019, 45 (3):  94-99.  doi: 10.15942/j.jcsu.2019.03.015 Abstract ( 1803 )   PDF (1230KB) ( 753 )   Save Objective: To explore the relationship between FMS and YBT test scores and sports injuries of Chinese elite military pentathlon athletes. Methods: Forty-four elite male and female military pentathlon athletes were tested by FMS and YBT, and the injuries during training were analyzed. The relationship between FMS and YBT test scores and injuries were analyzed. The results showed that: (1) The injury rate of elite military pentathlon athletes was high (52.27%) , The main injury sites were shoulder, waist and knee, accounting for about 77% of injury. (2) The FMS score of the injured athlete was 14.22 points, significantly (p <0.01) lower than the 16.67 points of the non-injured athlete. (3) The accuracy of damage prediction was 73.91% when FMS≤15 was used as the threshold to determine the damage, and the accuracy of damage prediction was 82.61 when the thresholds of X, Y, Z> 4 cm on both sides of YBT were used to determine the damage threshold.(4) The accuracy of the damage prediction is 100% when the combination of the two methods takes FMS≤15 points and X, Y, Z> 4 cm as the threshold value on both sides of YBT test. Conclusion: Both FMS and YBT tests can effectively predict the potential injury risk of military pentathlon athletes. If two test methods are combined, the accuracy of predicting the potential injury risk of athletes is better than that of single test method. It is suggested that when predicting the potential injury risk of athletes, the two test methods should be combined, and the weak links shown in the test should be targeted to improve the effect of injury prevention.
