Abstract:
The purpose of this study is to investigate the difference in aerodynamic properties between the feather shuttlecock and the synthetic shuttlecock. In particular, we focus on the aerodynamic stability of the two types of shuttlecock during impulsive change of an angle of attack (flip movement). Wind tunnel experiments are performed by using two types of the badminton shuttlecock (feather and synthetic shuttlecocks) to measure the fluid forces, and to visualize the flow fields around the shuttlecock. It is confirmed that the pitching moment coefficient at a near-zero angle-of-attack for feather shuttlecock is larger than that for synthetic shuttlecock. The results indicate that the feather shuttlecock demonstrates high stability in response to the flip phenomenon.

Abstract:
Shuttlecocks serve as one of the necessary sporting equipment to play badminton. The standard Shuttlecock buckets sold on the market are equipped with a total of 12 Shuttlecocks and the bucket body is long, which makes it time-consuming to pick up and causes palmar flexion and other usage problems. In view of this, the two brand-new designed shuttlecock buckets are introduced. This research aims to compare traditional shuttlecock buckets with two kinds of new buckets in order to find out whether they can provide users with a better experience. The experiment was evaluated by measuring wrist flexion angle and user pickup time and adopting a subjective questionnaire. The result indicated that the two new designed buckets are superior to the traditional buckets due to that they can help reduce wrist flexion angle and improve ball pick up efficiency. All in all, this study helps manufacturers to design and produce more reasonable shuttlecock buckets as it provides a new perspective on shuttlecock buckets design.

Abstract:
This paper presents the first scale resolving computational fluid dynamic (CFD) investigation of a geometrically realistic feather shuttlecock with rotation at a high Reynolds number. Rotation was found to reduce the drag coefficient of the shuttlecock. However, the drag coefficient is shown to be independent of the Reynolds number for both rotating and statically fixed shuttlecocks. Particular attention is given to the influence of rotation on the development of flow structures. Rotation is shown to have a clear influence on the formation of flow structures particularly from the feather vanes, and aft of the shuttlecock base. This further raises concerns regarding wind tunnel studies that use traditional experimental sting mounts; typically inserted into this aft region, they have potential to compromise both flow structure and resultant drag forces. As CFD does not necessitate use of a sting with proper application, it has great potential for a detailed study and analysis of shuttlecocks.

Abstract:
Aiming at the problem that the inheritance effect of shuttlecock is not ideal and the inheritance strategy is lack of pertinence, this paper puts forward a decision-making model based on game theory. Firstly, based on the inheritance data of shuttlecock movement, the shuttlecock movement set is established, and the normality, integrity, and standardization of the data set are tested. Then, using weighted theory and game theory, the shuttlecock motion set is divided, and according to the situation of each subset, the game decision-making method is selected. Finally, under the guidance of game decision-making method, the inheritance strategy of shuttlecock is obtained. The results show that the concept of shuttlecock inheritance ( OR = 1.232 , P < 0.000 ), public participation ( OR = 10.865 , P < 0.000 ), government support ( OR = 2.561 , P < 0.000 ), and multiangle inheritance measures ( OR = 0.965 , P < 0.000 ) all have an impact on the inheritance of shuttlecock. However, the propaganda is not in place ( OR = − 5.234 , P < 0.000 ), which inhibits the inheritance of sports shuttlecock. Therefore, sports institutions, relevant departments and colleges, and universities should formulate inheritance strategies and measures that meet the requirements from the above factors.

Abstract:
Shuttlecock is an excellent traditional national sport in China. Because of its simplicity, convenience, and fun, it is loved by the broad masses of people, especially teenagers and children. The development of shuttlecock sports into a confrontational event is not long, and it takes a period of research to master the tactics and strategies of shuttlecock sports. Based on this, this article proposes the use of machine learning algorithms to recognize the movement of shuttlecock movements, aiming to provide more theoretical and technical support for shuttlecock competitions by identifying features through actions with the assistance of technical algorithms. This paper uses literature research methods, model methods, comparative analysis methods, and other methods to deeply study the motion characteristics of shuttlecock motion, the key algorithms of machine learning algorithms, and other theories and construct the shuttlecock motion recognition based on multiview clustering algorithm. The model analyzes the robustness and accuracy of the machine learning algorithm and other algorithms, such as a variety of performance comparisons, and the results of the shuttlecock motion recognition image. For the key movements of shuttlecock movement, disk, stretch, hook, wipe, knock, and abduction, the algorithm proposed in this paper has a good movement recognition rate, which can reach 91.2%. Although several similar actions can be recognized well, the average recognition accuracy rate can exceed 75%, and even through continuous image capture, the number of occurrences of the action can be automatically analyzed, which is beneficial to athletes. And the coach can better analyze tactics and research strategies.

Abstract:
The forehand jump smash is an essential attacking stroke within a badminton player’s repertoire. A key determinate of the stroke’s effectiveness is post-impact shuttlecock speed, and therefore awareness of critical technique factors that impact upon speed is important to players/coaches. Three-dimensional kinematic data of player, racket and shuttlecock were recorded for 18 experienced players performing maximal effort forehand jump smashes. Joint angles and X-factor (transverse plane pelvis-thorax separation) were calculated at key instants: preparation, end of retraction, racket lowest point, turning point and shuttlecock contact. Peak shoulder, elbow, and wrist joint centre linear velocities, phase durations and jump height were also calculated. Correlational analyses were performed with post-impact shuttlecock speed, revealing significant correlations to peak wrist joint centre linear velocity (r = 0.767), acceleration phase duration (r = −0.543), shoulder internal/external rotation angle at shuttlecock contact (r = 0.508) and X-factor at the end of retraction (r = −0.484). Multiple linear regression analysis revealed 43.7% of the variance in shuttlecock speed could be explained by acceleration phase duration and X-factor at the end of retraction, where shorter acceleration phase durations and more negative X-factor at end of retraction caused greater shuttlecock speeds. These results suggest that motions of the proximal segments (shoulder and pelvis–thorax separation) are critical to developing greater distal linear velocities, which subsequently lead to greater post-impact shuttlecock speed.

Abstracts Badminton is one of the popular sports and suit for the wide range of ages, no matter young or old. However, compared to other sports, people also consider it’s not so environmentally friendly because of the high consumption rate of the shuttlecocks. In order to solve this problem and improve the resistance of shuttlecock damage, many manufacturers have studied to develop the synthetic shuttlecocks. Different from most of the shuttlecocks which are using plastic as the skirts, one manufacturer uses carbon fiber and foam material as the artificial feather to produce a Carbon Fiber Shuttlecock. Thus, the object of this study is Carbon Fiber Shuttlecock. Due to the flying speed of the shuttlecock is the fastest among all kinds of ball-type sports, the aerodynamic performance has mainly been taken into account as the subject while studying the characteristics of a shuttlecock. Thus the results of related researches often show in papers or academic journals. To present the aerodynamic characteristics of a shuttlecock, wind tunnel test is one of the best ways among various research methods. For this reason, besides to invite players for actual badminton games for test and comparison purposes, this study also uses a homemade small-size wind tunnel to collect data from both natural feather shuttlecock and Carbon Fiber Shuttlecock for comparison. The results of the comparison show that the shape of the shuttlecock looks more real alike with the feather shuttlecock, especially in the feather skirt which is completely different from that of the plastic badminton. In addition, after the actual badminton games, it’s also found that the durability of the carbon fiber shuttlecock has been improved. However, after some fast and long driven shots or smashes, the feather shaft and the fixing cotton thread were found becoming softened and it caused the speed of the shuttlecock faster and faster. Besides, the shaft was easily broken if it’s hit accidentally by the player’s racket. And, the results of wind tunnel tests show that at high wind speed, the resistance performance of carbon fiber shuttlecock is lower than that of natural shuttlecock. These phenomenons tell that to produce a carbon fiber shuttlecock still has room for improvement. Keywords: Carbon fiber, Wind tunnel, Drag

Shuttlecock is a sport developed from traditional Taiwanese folk custom sport, shuttlecock kicking. People started to investigate the equipment and rules since 1977, starting to performance in public place and school until 1980s. There has a considerable scale of populations participate in playing shuttlecock in Taiwan since the sport be developed. The motivation to write this dissertation is because the author had participated in the training of shuttlecock in 1999 and 2000, and had a great enthusiasm in playing shuttlecock. This research would discuss shuttlecock by historical analysis, literature review and interview, collecting, arranging, concluding and analyzing the historical data, aiming to discuss about how shuttlecock be developed in Taiwan. The scope of this research would be the history of shuttlecock, the change of shuttlecock equipment, the development of the organization, the competition of shuttlecock and the interview of shuttlecock founder, discuss about the growth of shuttlecock in different periods during 1977 - 2012. The result of this research: A. The mother of shuttlecock in Taiwan – Ming-Xiu Lee, she spent lots of time look into shuttlecock. B. Taipei shuttlecock association made active efforts in training the person who have the ability and set up the promotion policy only in the first ten years, however, the early retirement of the seeded teacher and the gap between senior and the younger generation is the main reason that the development stocked. C. It can be indicated that shuttlecock is stop and did not move forward because of in the long-term of shuttlecock competition in Taiwan is focusing only in the elementary school which located in Taipei.

Nonetheless, due to the recent increased popularity and higher standards towards this sport in many countries, considerable business opportunities in the related industries are impacted either directly or indirectly, and the most noticeable is the most expendable item of the sport—shuttlecock—and its manufacturing. For centuries, the shuttlecocks used in the sport of badminton are made of goose or duck feathers and have been used for both competitions or leisure events. However, the reduced supply of natural feathers over the years, and on top of it, the spread of the Avian Flu along with other epidemics, have made the supply sparse which resulted in the sharp increase in the cost of natural feathers, and hence the selling price of shuttlecocks affected. So far, there is no relief of this situation in sight. Seeking synthetic substitute products feasible and acceptable to manufacturers and consumers as a solution to solve the low-supply situation therefore has become a hot topic in the badminton community. This paper is a case study of synthetic shuttlecocks made from nylon material. The aspects to be looked into include the following: manufacturing process, the flight path, recovery time, the suitability for use in the actual games, durability of the products, and the level of emulation compared to the traditional feathered shuttlecocks. All these aspects are examined and analyzed to determine whether it is feasible or necessary to replace the shuttlecocks made from natural materials with the ones from the synthetic material. The use of synthetic shuttlecocks in the future, in our opinion, is expected to be bright.

The academic researches of shuttlecock skill on hand, for the most part, expound based on reviewing the history, teaching, and quantification. At the same time, this research differed from traditional research aspect. It focused on self-experiences, exchanged past me and future me, built a framework of experiencing stories about shuttlecock practice and performance, made a introspection and interpret the unique characteristics when doing shuttlecock performance; finally, excavated different gradations of beauty. There were three different beauties of shuttlecock skill: 1.Beauties from audiences’ viewpoints – “innovated, peculiar, amazing, beautiful, and difficult”. Inside shuttlecock performance, the audiences would be affected by innovated beauty, peculiar beauty, amazing beauty, entire beauty, and fluent beauty. 2.Beauty of enrichment of self-experience – there were four gradations of beauties which had been dig out what is buried inside kicking shuttlecock motions and variation of formations – stable beauty, blends beauty, synchronous beauty, and delicate beauty. Inside this beauty, it pursued the stabilities of “be rolled into one”, “throw – pause”, and “make a stand.” The stage property and body performance of synchronous beauty, gradations of various formation, and diverse body motions are all spotlights of beauties. 3.Vacant beauty of self-experience – the interaction between me and team members (or teachers) come into existence beauty of unspoken consensus, and beauty of disposition; besides, the team chemistry and love between men and women are all surmount the boundary of richness; and then, become aware of beauty from audiences’ viewpoints, the enrichment and vacant beauty of self-experience. It’s just like experiencing a beauty feast which three different kinds of beauties shuttle in shuttlecock kicking performance and let audiences broaden the outlook.

The shuttlecock game, one of the traditional Chinese folk sports, used to be a popular children’s game in ancient Chinese society, practiced to develop or maintain physical fitness. In today’s society that encourages all of its citizens to engage in physical exercises, the shuttlecock game is an activity that deserves furtherance because the shuttlecock, or jianzih, is small in size, easy to carry, and inexpensive, and the game itself does not require much space.Recently, we have a great concern about that the shuttlecock has been downfallen in our campus, through the case study in hua-yuan elementary school, we can keep track of its progress of shuttlecock development. Teacher Lu plays an important role at representative team in this school, taking all the pressure from both parents and school, attending all kinds of competitive contests not only domestic but also overseas, eventually, he become a legend. The shuttlecock representative team needs a long term training and efforts but shows as ephemeron on stage. I sincerely hope that this research regains the importance of shuttlecock games. Therefore, we could make more efforts to pass down the traditions and regard it as a cultural task.

Effect of the shuttlecock, a traditional Chinese physical activity, on health-related physical fitness is still unknown. Therefore, the present study was conducted to investigate the health-promoting effect of a shuttlecock intervention in young adults. Sixteen males and 14 females aged 21.9±2.3 (mean ± SD) and 22.6±0.8 years, respectively, participated the study voluntarily. All participators did not have shuttlecock experience before and were divided into exercise (EG) and sedentary control (CG) groups according to their wishes. The EG did SCK in any 3 days on a week for 12 weeks. The shuttlecock training program in the exercise day was set as following: 10-min shuttlecock, 5-min break, 10-min shuttlecock, 5-min break, and 10-min shuttlecock. Body composition, cardiopulmonary endurance, muscular power and endurance of lower limbs, and the range of motion (ROM) of hip joint of all participators were measured before and after the intervention and data were analyzed by paired Student t-test. On the first week, exercising pulse rate (EPR) of male and female EG was 60 % of their maximal pulse rate (MPR), respectively. On the 12th week, EPR of male and female EG elevated to 72 % and 73 % of the MPR. The results demonstrated that the abdominal skin fold of male EG (n=8) and the triceps skin fold, body weight, and % body fat of female EG (n=8) decreased significantly (p < 0.05). On the other hand, the abdominal skin fold of male CG (n=8) increased significantly. The resting systolic pressure of male EG decreased (121±15 vs. 110±14 mmHg) significantly. Besides, the exercise time on a cycle ergometer significantly increased in EG (female, 403±63 vs. 446±64 sec; male, 574±15 vs. 616±122 sec) after the intervention. However, the max and muscular power and endurance did not change in male CG and EG. Blood pressure of female EG showed an improve tendency neither with significance. According to the results, single leg standing shuttlecock is a low-middle intensity aerobic exercise. A 12-week shuttlecock program not only provides as an exercise with progressively moderate intensity but also promotes health-related physical fitness in young adults of both genders.

THE STUDY Of SHUTTLECOCK AND ACCURACY Of FOREHAND SMASH Of EXCELLENT BADMINTON PLAYERS Of ELEMENTARY SCHOOL AND SENIOR HIGH SCHOOL Graduate student: Wang Sin Siung Adviser: Hsu Tai Yen Abstract The Purposes of this study was to explore : a) whether there are differences between the ball speeds of the players (of elementary school and senior high school) aiming or not aiming at the target area. b) whether there are correlations between the initial ball speed and accuracy of the forehand smash of the players in elementary school and senior high school aiming at the target area. Methods: The participants of experiment were the elementary school team that won the national badminton championship boys’ group in 2014, 16 players of senior grades of AA Elementary School, Taichung City, average height: 150.81±8.63 cm, average weight: 38.31±6.82 Kg, and the senior high school team that won the silver medal in National High School Games, men's overall team, in 2013, 19 players of BB Senior High School, Taichung City, average height: 167.63±6.11 cm, average weight: 61.16±6.71 Kg. They played forehand smashes on the hitting area at 5.50 meters in front of the net. The researcher set one high speed camera, Casio EX-FX1 300Hz item model on the hitting area and the other one on the target area. Not aiming at any target area in the first round and served from the coach , the 35 players in the same hit zone made every effort on the 5 times of forehand smash, and the measured result was the initial ball speeds of forehand smash without target area; in the second round, the coach served the ball, and the participants played a forehand smash on the same hitting area with aiming at the 150cm * 150cm target area on the bottom line after the net. Each player had to hit the ball into the target area successfully for five times, thus the data of the initial velocity of forehand smash with aiming at the target area could be measured, and simultaneously, the error distance between the ball placement and the center of target area was also obtained. The experimental data of the initial velocity of forehand smash with or without aiming at the target area were analyzed by dependent sample t test (α = .05) to know whether the difference is significant. The experimental data of the initial velocity of forehand smash With aiming at the target area and the centroid error were analyzed by Pearson's Product-Moment Correlation Coefficient (PPMCC) and descriptive statistics (α = .05). Results: This study found the average velocity of elementary school group's forehand smash without and with aiming at the target area was separately 49.98±8.67 m/s. and 43.98±8.44 m/s. Besides, the average velocity of senior high school group was separately 74.23±9.04 m/s. and 60.06±11.55 m/s. The two groups' velocities between with and without aiming at the target area had both significant differences. As to the accuracy test of the forehand smash velocities of the elementary school group and senior high school group, the error distances of the placements were 48.94 ± 18.86 and 40.19 ± 18.06 cm, and the Pearson's correlation coefficients were separately 0.01, p=0.95 and -0.21, p=0.04. Conclusion: the velocity difference of forehand smash between with and without aiming at the target area in the two groups were both significant. This means there is a trade-off between velocity and accuracy. The senior high school group had high initial velocity and high accuracy in smash, and the velocity and centroid error were significantly negative correlated; this means the higher the velocity, the higher the accuracy, however, the velocity and error distance were not statistically correlated in the elementary school group.

ABSTRACT This study took grade school teachers who like shuttlecock as the example to explore participation motive, lasting factor, leisure benefit, and cost in 「the hobby type」 serious leisure participant. In addition, the author also compared the difference between serious leisure and casual leisure. This research adopted the qualitative research method. The author noted down the interview outline, and took the structural and open in-depth interview based on the Stebbins’ serious leisure theory. Those participant with more than two years badminton experience and must played badminton 3 times per week in the latest 3 months including 5 males and 5 femaless. The result of this study indicates: First, the participation motive has 8 items included self-interest, release of pressure, body building, fostering exercise habit, pursued the skill, the peer’s invitation, making friends and recreation. To analyze the attitude of these interviewees and content proportion, the author found body building, the peer’s invitation and making friends are the stronger participation motive. Second, the most important reason of these interviewees participation motive included enjoying the interaction atmosphere, promotion of the interpersonal relationships, physical and mental healthy promotion, experiencing the good recreation feelings, the establishment of routine habit, gaining the achievement, pursuing the better performance, deeply impression, others' support and recognition of the group. Third, regarding to the analysis of leisure benefit, there are 4 respects which include (1) The psychological benefit had self-fulfillment, self-actualization, self-performance, the elevation of self-image and self-satisfaction. (2) The physiological benefit had keeping healthy, energy buildup, keeping good shape, body and mind rebuild, resuming spirit, abreacting emotion, adjusting mood, forgetting anxiety and releasing pressure. (3) Social benefit part included all was helpful to the family and interpersonal relationships. (4) Benefit of other respects included helpful to the individual’s job and life. Fourth, in the analysis of the leisure cost, the author found that the cost interviewees had to pay in the badminton activity includes (1) Negative mood, for instance: tense, frustration, anxiety, pressure, hate, boredom, disappointment, etc. (2) Body injury. (3) Conflict of the interpersonal relationships. (4) Negative effects to the work, etc. All interviewees took the positive attitude to face the leisure cost that they have to stand. They also recognized that the benefit when they participated the activity was far more than these costs. Therefore, they were willing to continue to participate seriously. Fifth, the differences between serious leisure and casual leisure found by this research include (1) Relatively having the sense of achievement. (2) Having more interpersonal relationship. (3) Relatively being helpful to physically and mentally health. (4) Relatively having more demand in skill. (5) Relatively having more fun. (6) Relatively having the regularity. (7) Relatively having the security. (8) Relatively having convenience, etc. Some interviewees expressd that especially interpersonal relationship can be regarded as the unique part comparing badminton activity with other recreation activity. In addition, it was helpful in physically and mentally health.

THE EFFECTS OF SHUTTLECOKE SPEED AND ACCURACY OF FOREHAND SMASH WITH OR WITHOUT TARGET AREABY EXCELLENT BADMINTON PLAYERS IN JUNIOR HIGH SCHOOL Advisor: Hsu Tai-Yen Student: Lin Wan Cheng Abstract Purpose:To measure whether there is a correlation between the shuttlecoke speed and accuracy of a forehand smash with or without aiming at the target area by the excellent players in junior high school.Methods: The subjects of this study were the 15 badminton player,average height:161.46±7.98 cm, average weight: 49.73±9.75 Kg,belonging to the badminton team of the Department of Junior High School, OO Senior High School, Taichung City which won the National Badminton Championship for Junior High School Studentsboys’ group in 2015. They played forehand smashes on the hitting area at 5.50 meters in front of the net. The researcher set one high speed camera,Type:Casio EX-FX1,300Hz, on the hitting area and the other one on the target area. The experiment was divided into two runs. Not aiming at any target area in the first round, each player made every effort on the forehand smash, and each player had to hit the ball into the target area successfully for five times. When the 15 players all finished their actions, the first round ended.In the second round,each player made every effort on the forehand smashwith aiming at the target area and had to hit the ball into the target area successfully for five times; When the 15 players all finished their actions, the second round ended. In the whole experimental process, the balls were all served by hand. The experimental data were analyzed by Dependent Sample T Test (α = .05) to know whether the difference of the shuttlecoke speed of forehand smash with or without aiming at the target area is significant. Then the data was also analyzed byPearson's Product-Moment Correlation Coefficient (PPMCC) to know whether each player’saverage shuttlecoke speedand accuracyof forehand smash is correlated. Results:This study found the average shuttlecoke speed of forehand smash without aiming at the target area was 55.64 m/s and the average shuttlecoke speed of forehand smash with aiming at the target area was 47.3 m/s; the test result was significant. The accuracyof forehand smash with aiming at the target area was 42.72 cm, and the standard deviation was 20.62 cm. After analyzing the correlation between the shuttlecoke speed and accuracy of forehand smash with aiming at the target area, the researcher obtained a non-significant result, r=-0.08 and p=0.51.Conclusion: It shows whether aiming at a specific target area significantly influences the shuttlecoke speed of forehand smash of the excellent players in junior high school. After analyzing the correlation between the shuttlecoke speed and accuracy of forehand smash with aiming at the target area, the researcher obtained a non-significant result. This means there is no correlation between the average shuttlecoke speed and accuracy of forehand smash with aiming at the target area of the excellent players in junior high school.

Abstract:
This paper presents a class project that can be performed in a junior-level fluid mechanics course. Students gain experience in design and conducting experiments, and in reviewing the relevant technical literature. Experiments were conducted to determine the drag coefficient of a badminton shuttlecock. Two types of testing were conducted: wind tunnel tests of a full-scale model, and drop tests using a high-accuracy radar gun. The drag coefficients calculated from these measurements were then compared to the limited data available in the literature. The range of drag coefficients measured was from 0.55 to 0.65.

Abstract:
Mixing performance of an active mixer which mixes two fluids by three-dimensional flow surrounding a rotating shuttlecock rotor in continuous flow is numerically investigated. The mixer consists of a step contraction-expansion microchannel and a shuttlecock micro-rotor placed in the step. The obtained results show that mixing quality of solution does not depend on neither rotation speed nor mean velocity in the mixer, but rather on the ratio of tip paddle velocity of the rotor to the mean velocity (i.e. Strouhal number). Streaklines demonstrate that two fluids from the inlet can penetrate into the space between the paddles of the rotor, and then are mixed here before flowing to the exit channel. In small Strouhal number (∼10) cases, two fluids are twisted 90 degrees after passing the rotor region. In the other words, mixing in downstream flow behind the rotor takes place in the height instead of the width of the exit channel, which makes the mixer applicable for channels with high aspect ratio of the cross section. It is observed that mixing is dominantly enhanced in the rotor region and increasing Strouhal number results in faster mixing in the mixer.
