The results showed that after intensive training for one week, serum CK levels were significantly increased by 57.53 mmol/L （P〈0.05）. After regulation of the training intensity, average serum CK levels were increased by 21.79 mmol/L （P〈0.05）. BUN contents were increased by 0.83 mmol/L on average with the difference being not significant （P〉0.05）. After intermittent training, there was significant difference in the average increased levels of serum CK in athletes （P〈0.05）. There was significant difference before and after regulation of training （P〈0.05）. The increased levels of BUN were 0.78 mmol/L without significant difference （P〉0.05）. It was concluded that serum CK was one of the biochemical indicators monitoring the training load sensitivity of badminton athletes, but BUN was of little value in monitoring the training load. Both serum CK and BUN recovered slowly after one-week intensive training and intermittent training, suggesting the metabolic mechanism of human body in training needs further study.展开更多

Based on a self-report questionnaire survey, we included 461 individuals （102 middle school students, 134 high school students, and 225 university students） with a history of shoulder pain in the previous year and 541 individuals with no shoulder pain in the previous year. Then, we performed logistic regression analysis of individual characteristics and history of shoulder pain to analyze the factors associated with shoulder pain onset. Analysis of patients excluding those currently experiencing shoulder pain indicated that a history of shoulder pain （〉 1 year previously） predicted shoulder pain onset. Analysis of patients excluding those with a history of shoulder pain indicated that undergoing care, being of university age, having a long history of competing, and short cool-down times were associated with recurrent pain. However, results were different for each age group. The fact that half the Japanese middle school, high school, and university badminton players had a history of shoulder pain suggests that they will experience recurrent shoulder pain. The results also suggest that different factors are important in each age group. Thus, it is critical to establish evidence-based countermeasures to prevent shoulder pain that interferes with play.展开更多

Thinking teaching method is not only a kind of the change of teaching methods, as well as change of teaching ideas, it focuses on teaching, teaching objectives, teaching idea has profound changes, better reflect the ideology of the quality education. Practice the thinking teaching method for physical education teachers have a new teaching concept, the value of the face up to the cultivation of the ability and intelligence. At the same time also require physical education teachers have a relatively wide range of knowledge, especially about scientific discovery and scientific knowledge of thinking. With the combination of the general interactive teaching and practice teaching approaches, we propose the novel paradigm for badminton education which holds the vital significance.展开更多

The highest launching velocity of the shuttlecock by professional badminton players exceeds speeds of over 83.3 m/s （300 km/hr）. In this study, a new badminton server machine was developed. The badminton machine can launch the shuttlecocks at wide range of speeds up to 52.8 m/s （190 km/hr） and with many shot types such as smash, clear and so on, which are easily achieved. The finite element models of a shuttlecock with feathers and the badminton machine were made, and the launching simulations of the shuttlecock were tried. The roller with a large diameter attained a higher speed of the shuttlecock than the small rollers for all kinds of launching conditions. The taper angles of the roller edge and the insert height of the shuttlecock relative to the roller surface were optimized for attaining the maximum shuttle speed by the response surface approach. After the optimization, the performance of the badminton machine had been improved about 7% as the shuttle speeds increase and the stress causing the shuttle deterioration decreased.展开更多
