Acute high altitude disease(AHAD), which can be divided into acute mountain disease (AMS), high altitude pulmonary edema (HAPE) and high altitude cerebral edema (HACE), is one of the special illnesses occurred at high altitude, commonly encountered by travelers to high altitudes (>2 500 m), which affects people's work capacity and health and could be even a life-threatening disease. Despite extensive investigations over the last century, the pathophysiology of AHAD remains elusive. Nevertheless, numerous researches have confirmed the existence of AHAD susceptibility differences. The aim of this paper was to review the epidemiological evidence for a genetic component to the various forms of AHAD so far, as well as to supply helpful reference to its epidemiological studies.

Biological chip technology has penetrated into all aspects of life, and its application in the field of sports is relatively small. Through the theory analysis of the characteristics of biological chip, the basic principle of technology, and combined with the field of sports, which can predict the biological chip for gene selection of athletes and athletes with different racial comparison of gene sequences, and explore the rules and mechanism of exercise-induced fatigue, and accelerate eliminate fatigue, and improve exercise capacity to provide scientific research and application means. At the same time, the physiological mechanism of human's movement ability could be explored at the molecular level, and enriches the contents of sports physiology and sports genetics. Bio chip in the field of sports will have a broad prospect and greatly promote the development of sports biology and the pace of development. Source

Purpose: The purpose of the present study was to examine the effects of a 24-week Tai Chi exercise intervention on balance and other physical changes such as flexibility and reaction time (RT) among healthy older males. Methods: Thirty-eight male subjects aged 55-65 years without prior Tai Chi experience were recruited from a local community in Shanghai, China. A 60-min Tai Chi exercise session was performed three times a week for 24 weeks. Changes in RT, sit-and-reach flexibility and balance (static balance with eyes open and closed respectively) were measured before and after the Tai Chi intervention. Results: After the 24-week Tai Chi intervention, the choice RT (p< 0.05) decreased, and sit-and-reach flexibility improved (p< 0.01) over the pre-test (7.8 ± 6.2 vs. 7.1 ± 3.0. cm). Sway length, area, X-axis deviation amplitude and Y-axis deviation amplitude performance decreased significantly after the intervention with a double-foot stance with eyes open (p< 0.05). Sway length, area and average sway speed showed a statistically significant decrease after the intervention with the double-foot stance with eyes closed. In the single-foot stance with eyes open condition, sway length and average sway speed showed a statistically significant decrease (p< 0.05). Conclusion: The 24-week Tai Chi exercise intervention had a positive influence on balance control in older males. © 2012. Source

Context. Cordyceps sinensis (Berk.) Sacc. (Clavicipitaceae) is a famous medicinal fungus (mushroom) in Chinese herbal medicine. Polysaccharides from Cordyceps sinensis (CSP) have been identified as active ingredients responsible for its biological activities. Although many pharmacological actions of CSP have received a great deal of attention, research in this area continues. Objective: The current study was designed to investigate the effects of CSP on exhaustive exercise-induced oxidative stress. Materials and methods: The mice were divided into four groups: control (C), low-dose CSP treated (LC), intermediate-dose CSP treated (IC) and high-dose CSP treated (HC). The treated groups received CSP (100, 200 and 400mg/kg, ig), while the control group received drinking water for 28days, followed by being forced to undergo exhaustive swimming exercise, and some biochemical parameters including superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT), malondialdehyde (MDA) and 8-hydroxy-2′- deoxyguanosine (8-OHdG) were measured using detection kits according to the manufacturers' instructions. Results: Compared with the C group, exhaustive swimming time was significantly prolonged in the LC, IC and HC groups (p<0.05); SOD activities in serum, liver and muscle were significantly higher in the IC and HC groups (p<0.05); GPx activities in serum, liver and muscle were significantly higher in the LC, IC and HC groups (p<0.05); CAT activities in serum, liver and muscle were significantly higher in the HC groups (p<0.05); MDA and 8-OHdG levels in serum, liver and muscle were significantly lower in the LC, IC and HC groups (p<0.05). Discussion and conclusion: The results obtained herein indicate that CSP could ameliorate exhaustive exercise-induced oxidative stress. © 2014 Informa Healthcare USA, Inc. All rights reserved.
