A Comparison of Student and Student-Athlete Drug Use and Attitudes Toward Drug Testing of Athletes

Munson, J.H. (Jerome Harlan) 08 1900 (has links)
In response to a NCAA ruling, North Texas State University (NTSU) launched a comprehensive drug testing, drug education and counseling program for its athletes effective August 1, 1986. This study assessed and compared NTSU student-athlete and student alcohol and drug use. In addition, attitudes toward a variety of sports-related drug topics, including mandatory athletic drug testing, were assessed and compared. The study revealed significant differences between student-athletes and students in drug use of the following: steroids, marijuana, cocaine, psychedelics, and amphetamines. Both groups favored mandatory drug testing of athletes.

Avaliação de equilíbrio em esportistas após a reconstrução anatômica do ligamento cruzado anterior nas posições anteromedial e central: estudo clínico randomizado / Postural balance evaluation in sport practitioners after anatomical anterior cruciate ligament reconstruction on the anteromedial and central footprint area: randomized clinical trial

Oliveira, Danilo Ricardo Okiishi de 17 May 2018 (has links)
Introdução: Na reconstrução anatômica do ligamento cruzado anterior (LCA) com banda simples, o diâmetro dos túneis não preenche totalmente sua área de origem e inserção. Estudos recentes sugerem que a banda anteromedial teria um papel dominante na função estabilizadora do LCA em qualquer grau de flexão, o que favoreceria o posicionamento dos túneis nessa região. No entanto, ao se buscar reproduzir a função das duas bandas com um enxerto simples, a escolha mais intuitiva é posicioná-lo na região central. O posicionamento inadequado do enxerto poderá resultar em uma instabilidade residual, mais evidente em indivíduos com alta demanda funcional, como é o caso de esportistas. Retomar a prática esportiva no mesmo nível não depende somente da estabilidade isolada do joelho, é preciso que o equilíbrio postural seja reestabelecido. O objetivo deste estudo foi comparar o posicionamento do enxerto na região anteromedial ou central na origem e inserção do LCA. Métodos: Trata-se de um estudo clínico prospectivo e randomizado, incluindo 42 esportistas (Tegner > 5) com lesão do LCA alocados para serem submetidos àreconstrução anatômica na posição anteromedial (22 pacientes - Grupo AM) ou central (20 pacientes - Grupo C). O desfecho primário foi obtido pelo valor médio da oscilação do centro de pressão (CP) de cada indivíudo no plano mediolateral (Xavg) avaliado na plataforma de força com apoio monopodálico simulando a posição de chute aos 6 meses de pós-operatório, enquanto os demais parâmetros de posturografia, escalas de Tegner, Lysholm, IKDC subjetivo, hop test e avaliação isocinética foram considerados desfechos secundários. Todos os resultados foram avaliados aos 6 e 12 meses, com exceção da escala de Tegner, avaliada somente aos 12 meses. Resultados: Na avaliação dos dados de posturografia fornecidos pela plataforma de força, o grupo C apresentou melhores resultados quando comparados ao grupo AM em três parâmetros de oscilação mediolateral do CP: valor médio (Xavg) na posição de chute aos 6 meses (-0,43 ± 0,15cm vs. -0,87 ± 0,18cm respectivamente, p < 0,05), deslocamento máximo (Xmax) na posição de apoio monopodálico simples aos 12 meses (1,05 ± 0,18cm vs. 1,28 ± 0,31 cm respectivamente, p < 0,05) e valor médio na posição de flexão do joelho aos 6 meses (0,31 + 1,35cm vs. -1,03 + 1,18cm respectivamente, p < 0,05). O grupo C também apresentou melhores resultados quando comparado ao grupo AM nas seguintes avaliações: índice de simetria do hop test aos 6 meses (93 ± 7% vs. 84 ± 17% respectivamente, p < 0,05) e aos 12 meses (100 ± 7% vs. 92 ± 7% respectivamente, p < 0,05) e deficit do pico de torque na velocidade angular de 60o/s aos 6 meses (12,55 ± 9,77 Nm vs. 22,9 ± 17,89 Nm respectivamente, p < 0,05). Conclusões: A reconstrução anatômica do LCA na posição central apresentou melhores resultados em três parâmetro de posturografia relacionados a oscilação no plano mediolateral (incluindo o desfecho primário), melhor índice de simetria no hop test e menor deficit do pico de torque na velocidade angular de 60o/s aos 6 meses, quando comparados à reconstrução na posição anteromedial. Não houve diferença significante quanto ao número de complicações / Introduction: Bone tunnel diameters in anatomical single-bundle anterior cruciate reconstruction cannot fulfill the footprint area. The latest studies have suggested that the anteromedial bundle might play a dominant role in ACL function at any flexion degree. This fact could support placing the bone tunnel on the anteromedial bundle footprint. However, positioning the graft at the center of the footprint could be a more efficient way to mimic part of the two-bundle function. Improper graft positioning may result in residual instability, particularly in individuals with higher functional demand, such as sport practitioners. Returning to their sport at the same level as before their injury could not be defined by knee stability alone; a global evaluation provided by more comprehensive parameters, such as postural balance, should also be included. The main purpose of this study is to compare grafts on anteromedial or central area positions in an ACL footprint. Methods: A prospective, randomized clinical study included 42 sports practitioners (Tegner > 5) with ACL injury undergoing anatomic ACL reconstruction on the anteromedial footprint (22 patients - AM group) or at the central footprint area (20 patients - Group C). The primary outcome was based on a mean center pressure (CP) mediolateral oscillation parameter analysis of each individual simulating a kicking motion on a force plate. Other posturography parameters, Tegner, Lysholm and IKDC subjective scales, a hop test and an isokinetic evaluation were considered as secondary outcomes. All results were evaluated at 6 and 12 months, with the exception of the Tegner scale, which was evaluated only at 12 months. Results; Group C presented better results in three posturography parameters when compared with Group AM: mean mediolateral plane oscillation with kicking position at 6 months (-0,43 ± 0,15cm vs. -0,87 ± 0,18cm respectively, p < 0.05), maximum CP lateral displacement with the one leg standing position at 12 months (1,05 ± 0,18cm vs. 1,28 ± 0,31 cm respectively, p < 0.05) and mean mediolateral plane oscillation with knee flexed position (0.31 ± 1.35 cm vs. -1.03 ± 1.18 cm respectively, p < 0.05) and). Group C also presented better results in the following evaluations: symmetry index in the hop test at 6 months (93 ± 7% vs. 84 ± 17% respectively, p < 0.05) and at 12 months (100 ± 7% vs. 92 ± 7%, respectively, p < 0.05) and torque peak deficit on angular velocity of 60 o/s at 6 months (12.55 ± 9.77 Nm vs. 22.9 ± 17, 89 Nm respectively, p < 0.05). CONCLUSION: Anatomic single bundle ACL reconstruction in the center of the ACL footprint shows better results compared with the anteromedial ACL footprint area in three posturography parameters related to coronal plane balance, index of symmetry in the hop test and the peak of torque deficit on an angular velocity of 60 o/s at 6 months. Surgical complications were similar in both groups

O Atletismo é uma modalidade esportiva que possui provas com demandas energéticas diferentes: potência (P) para saltadores, velocistas e lançadores e resistência (R) para corredores de longas distâncias e marcha atlética. É possível observar diferenças destas características com as possíveis variações da frequência do genótipo DD (deleção), II (inserção) e heterozigoto ID na ACE, bem como da frequência genotípica RR, RX e XX na ACTN3. O presente artigo tem por objetivo correlacionar à recorrência do polimorfismo ACE (Enzima Conversora da Angiotensina) da ACTN3 nos atletas de Atletismo. Estudos anteriores relacionaram estes polimorfismos à capacidade física demandada em outras modalidades. A amostra foi composta por 50 atletas (39 homens e 11 mulheres), com idade de 13 a 38 anos, participantes de equipes de atletismo, que foram então agrupados em função da característica de suas provas (Potência ou Resistência). O estudo apresentou diferenças significativas entre as amostras e o esperado para esta frequência pelo equilíbrio de HardyWeinberg (p=0,0067, para o Polimorfismo da ACE e p=0,0143, para o polimorfismo da ACTN3), no que tange a capacidade dominante da prova e também relacionada ao perfil da população brasileira, grupo controle comparado da literatura (p=0,0223, para o Polimorfismo da ACE e p=0,024, para o polimorfismo da ACTN3). O estudo apresentou uma recorrência de 71,7% somados os genótipos DD e ID, corroborando assim com estudos prévios e 33,3% do genótipo II, conflitando assim com pesquisas anteriores. / The Track and Field’s is a sport that has tests with different energy demands: power (P) for jumpers, sprinters and throwers and resistance (R) for runners and race walking long distances. It is possible to observe differences in these characteristics with possible variations of the D allele (deletion) and I (insert). This article recurrence of ACE (Angiotensin Converting Enzyme) in Track and Field’s athletes.Previous studies have linked this polymorphism to the defendant physical capacity in other modes. The sample was composed of 25 athletes (16 men and 10 women) from 13 to 38 years old with participants in a track team, which were then grouped according to the characteristic of this evidence (power or strength). The study showed significant differences between the samples and the expected for this frequency by the Hardy-Weinberg equilibrium (p = 0.0067, for the ACE polymorphism and p = 0.0143 for the ACTN3 polymorphism), regarding the capacity (P = 0.0223, for the ACE Polymorphism and p = 0.024 for the ACTN3 polymorphism). The study presented a recurrence of 71.7% in addition to the DD and ID genotypes, thus corroborating previous studies and 33.3% of genotype II, thus conflicting with previous research.

Uticaj faktora rizika na povređivanje prednje ukštene veze kolena u toku sportskih aktivnosti / Influence of risk factors on anterior cruciate ligament injuries during sports activities

Krstić Vladimir 13 November 2020 (has links)
<p>Ispitivanu grupu činilo je 1247 ispitanika sa povredama prednje ukr&scaron;tene veze kolena koji su operativno lečeni u periodu 2012.-2017. godina na Klinici za ortopedsku hirurgiju i traumatologiju Kliničkog centra Vojvodine. Ciljevi istraživanja bili su utvrđivanje uticaja nivoa sportske aktivnosti i mehanizama povređivanja na nastanak povreda prednje ukr&scaron;tene veze kolena, zatim uticaj spolja&scaron;njih faktora rizika (vrsta sporta, rang takmičenja, vrsta podloge, trening ili utakmica, period treninga) na nastanak povreda prednje ukr&scaron;tene veze kolena, odnosno uticaj unutra&scaron;njih faktora rizika (pol, starost, BMI) na nastanak povreda ove strukture kolena. Od ukupnog broja ispitanika njih 517 (41,5%) su činili aktivni sportisti, a 730 (58,5%) rekreativci. Značajnu većinu u posmatranom uzorku su činili mu&scaron;karci (82,6%), osobe starosti od 16 do 25 godina (62,6%) i normalno uhranjenje osobe (62%). Do povrede prednje ukr&scaron;tene veze do&scaron;lo je kod njih 504 (40,5%) prilikom aktivnog bavljenja sportom, dok su se povrede prilikom rekreativnog bavljenja sportom dogodile kod 741 ispitanika (59,5%). Među aktivnim sportistima, vi&scaron;e od dve trećine se takmičilo na internacionalnom ili republičkom nivou, odnosno u najvi&scaron;im rangovima takmičenja. Kontaktnim kolektivnim sportovima (fudbal, ko&scaron;arka i rukomet) bavilo se 77,9% ispitanika. Nekontaktnim sportovima kao &scaron;to su odbojka, borilački sportovi i skijanje bavilo se 22,1% ispitanika, pri čemu je najveći broj povreda nastao prilikom igranja fudbala (51,3%). Statistički značajno vi&scaron;e povreda (i prilikom aktivnog i prilikom rekreativnog bavljenja sportom) je nastalo bez direktnog kontakta (nekontaktne povrede koje su činile 78,7% povreda), pri čemu je najveći broj povreda nastao usled promene pravca i ritma kretanja. Kod aktivnih sportista najvi&scaron;e povreda dogodilo se na utakmicama (73,8%), slede povrede na treningu (24,1%), dok se na rekreaciji povredilo svega 2,1% ispitanika. Značajno vi&scaron;e povreda dogodilo se na sredini bavljenja sportskom aktivno&scaron;ću (47,4%) u odnosu na povrede na zagrevanju, početku, odnosno kraju sportske aktivnosti. Povrede su značajno če&scaron;će nastajale na travi (42%) i parketu (28%), nego na drugim vrstama podloge. Najveći broj ispitanika povredio se noseći patike prilikom bavljenja sportskom aktivno&scaron;ću. Postoje značajne razlike u kontekstu povređivanja u zavisnosti od pola ispitanika. Žene su u značajno većem procentu povređivane prikom aktivnog bavljenja sportom, dok su se mu&scaron;karci če&scaron;će povređivali na rekreaciji. Žene su se najče&scaron;će povređivale na rukometu, mu&scaron;karci na fudbalu. U odnosu na mu&scaron;karce, kod žena su povrede znatno ređe nastajale prilikom direktnog kontakta, a kad je u pitanju mesto povređivanja, žene su se če&scaron;će nego mu&scaron;karci povređivale na treningu. Preko 50% žena je povređeno na parketu, dok se najveći broj mu&scaron;karaca povredio na travi. Ispitanici sa prekomernom telesnom masom značajno če&scaron;će su se povređivali prilikom rekreacije, dok su se normalno uhranjeni če&scaron;će povređivali prilikom aktivnog bavljenja sportom. Faktori rizika za nastanak povreda prednje ukr&scaron;tene veze su brojni i specifični, odnosno da za svaku populacionu kategoriju postoje rizici, ali se uočava da su u svim sportovima, na svim podlogama i kod svih ispitanika povrede najče&scaron;će nastajale nekontaknim mehanizmom povređivanja. Formiranjem registra povređenih omogućilo bi se bolje razumevanje faktora rizika i njihovog međusobnog uticaja, kao i definisanje profila osoba pod najvećim rizikom za nastanak povrede prednje ukr&scaron;ene veze kolena. Na taj način obezbedile bi se potrebne informacije za planiranje preventivnih programa usmerenih na smanjenje rizika od povređivanja i omogućilo bi se sprovođenje odgovarajućih mera selektivne prevencije.</p> / <p>The study group consisted of 1247 respondents with anterior cruciate ligament injuries who were surgically treated in the period 2012-2017. at the Clinic for Orthopedic Surgery and Traumatology of the Clinical Center of Vojvodina. The objectives of the study were to determine the impact of sports activity levels and injury mechanisms on the occurrence of anterior cruciate ligament injuries, then the impact of external risk factors (type of sport, competition rank, type of surface, training or match, training period) on the occurrence of anterior cruciate ligament injuries and the influence of internal risk factors (gender, age, BMI) on the occurrence of injuries of this knee structure. Out of the total number of respondents 517 (41.5%) were active athletes, and 730 (58.5%) were recreational athletes. A significant majority in the observed group were men (82.6%), persons aged 16 to 25 years (62.6%) and normal BMI respondents (62%). Anterior cruciate ligament injury occurred in 504 of them (40.5%) during active sports, while injuries during recreational sports occurred in 741 respondents (59.5%). Among active athletes, more than two thirds competed at the international or national level- in the highest ranks of the competition. Contact collective sports (football, basketball and handball) were practiced by 77.9% of respondents. 22.1% of respondents practiced non-contact sports such as volleyball, martial arts sports and skiing. The largest number of injuries occurring while playing football (51.3%). Statistically significantly more injuries (both during active and recreational sports) occurred without direct contact (noncontact injuries-78,7% of total injuries number), with the largest number of injuries caused by changes in the direction and rhythm of movement. Among active athletes, most injuries occurred in matches (73.8%), followed by injuries in training (24.1%), while only 2.1% of respondents were injured in recreation. Significantly more injuries occurred in the middle of engaging in sports activity (47.4%) compared to injuries during the warm-up, beginning and end of sports activity. Injuries occurred significantly more often on grass (42%) and floor (28%) than on other types of surfaces. Most of the respondents were injured wearing sneakers while doing sports. There are significant differences in the context of injury depending on the gender of the respondents. A significantly higher percentage of women were injured during active sports, while men were more often injured during recreational sport activities. Women were most often injured in handball, men in football. Compared to men, injuries were much less common in women during direct contact, and when it comes to the place of injury, women were injured more often than men during training acitivities. Over 50% of women were injured on the floor, while the largest number of men were injured on the grass. Subjects with overweight were significantly more likely to be injured during recreational sport acitivites, while those with normal BMI were more likely to be injured during active sports. Risk factors for anterior cruciate ligament injuries are numerous and specific and there are risks for each population category, but it is noticed that in all sports, on all surfaces and in all subjects, injuries were most often caused by a noncontact injury mechanism. The formation of a Register of injuries would enable a better understanding of risk factors and their mutual influence, as well as the definition of the profile of persons at greatest risk for the occurrence of an anterior cruciate ligament injury. This would provide the necessary information for planning prevention programs aimed at reducing the risk of injury and would enable the implementation of appropriate selective prevention measures.</p>

Sportovně rekreační centrum Vsetín, Ohrada / Sports and Relaxation Centre Vsetín, Ohrada

Tallmayer, Dominik January 2021 (has links)
This paper aims to elaborate an urbanistic study focused on the establishment of a multifunction athletic and recreational area located in Vsetín-Ohrada, carrying the name of the location, Ohrada. The reason to elaborate on this project is the current desolate state of the area, which already does not fulfil its purpose and serves only as lodgings and as a facility for the tennis club. My approach for this project implies identified accidence of buildings with an emphasis on maximal use of daylight, open spaces, green areas, and social interactions. All of these parts connect ideas and needs of future generations and deliver into the area new Genio Loci. For me, the biggest challenge in this complex area is finding the answer to meaningful use of the big amount of soil that is part of the canker tribune. The solution for this challenge might be in the creation of new access paths and footbridge to the buildings which provide several parts of space with different atmosphere and purpose. The main idea was the creation of a leisure public space with an emphasis on the variability of used areas that serve people from all age groups. It creates several main areas that divide the location and deliver various atmospheres for each generation. Additionally, the area as a whole is open and accessible to the public. A sign of long-term functional society is the ability of considerable behaviour toward public areas. Space in front of and between buildings happened to be more important than the building itself. In this case, we can talk about public life that is sustainable in time.

Title: Using the FMS method for injury prevention in older school-age athletes Objectives: The objective of this diploma thesis is to show new methods and approaches used nowadays for preventing injuries in athletics. In order to fulfil the objective, it was necessary to gather as much information as possible about the characteristics of older school-age children, the issue of injuries at this age, in general and in athletics specifically. Understanding the connections, two methods were then selected and described in detail which focus on preventing injury and which are used in athletics as well as other sports. One of these methods is the ComplexCore+ method which was invented and described by Austrian physical therapist and coach Roman Jahoda. This method is widely used in athletics and its main focus is the local and global stabilization of the body. In this thesis, however, I have more focused more on describing and analysing the principles and options for using the Functional Movement Screening (FMS) method. FMS is founded in physical therapy and was created by American physical therapist and coach Gray Cook. The purpose of the method is to identify and assess the quality of basic movement patterns through 7 mobility tests. In order to fulfil the objective of the thesis, two FMS tests were...

觀念、組織與實踐:日治時期臺灣體育運動之發展(1895-1937) / Concept, organization, and practice— the athletic development of Taiwan during Japanese occupation period (1895-1937)

1948年5月,上海舉辦第七屆全中國運動會,臺灣首次組隊參賽即一鳴驚人,榮獲男子田徑總冠軍,同時更展現守秩序、法紀律、團結合作、服從裁判的運動精神。不論場內的運動實力和場外的運動風範,皆被大會評為「全國第一」。究其因,實肇基於日本統治期間致力發展體育運動所展現的成果。事實上,臺灣在日本統治之前,近代式體育運動僅在西洋勢力所及的範圍內施行,成效自是相當有限,迨至日治時期,乃藉由學校教育與社會體育兩大方向,開始全面性、普遍地提倡體育運動而獲致相當程度的發展成果。值是之故,本論文主旨即在探討日本統治下的臺灣,究竟為何/如何發展體育運動,以及有何成效。 本文係以當時臺灣地區運動員的競賽為主,包含內地人(日本人)、本島人(臺灣人)以及高砂族(原住民),因為此三種族群皆是當時臺灣運動代表隊的組成份子,以做為主要的論述對象更能得知當時臺灣體育運動的發展情況。在論文內容方面,首先,從近代西洋體育運動的興起與發展談起,隨著歐美列強國力的擴張將其科技文明與生活形態傳至亞洲,再至日本明治維新前後追求改善國民體格而向學習歐美體育運動,而臺灣即在此時代背景之下被納為日本殖民地。其次,探討日治時期各界人士對於體育運動所提出的觀念看法,以說明發展體育運動的動機與目的。再次,討論推行體育運動的主要機構,主要著眼於人事、經費以及如何運作等方面,以瞭解是由哪些人/在什麼樣的時代背景之下/如何從事體育運動的發展。第四、討論臺灣運動選手參加各項運動競賽的成績表現,主要以全島性比賽,以及與鄰近的朝鮮、滿洲、日本、菲律賓等地的比賽成績作較,可大致明瞭臺灣的運動技術水準。第五、分析社會領導階層人士所從事的休閒運動,以考察當時是哪些休閒運動最受是有錢有閒階級的喜愛,並從中討論體育運動的發展概況。 經由本文的討論發現,日治時期體育運動的發展係在官方強力主導、民間配合實施之下進行推廣。其次,臺灣的體育組織是日本帝國體育組織在殖民地的分支機構,臺灣全島性的運動比賽成為日本全國性比賽的地方預選賽,臺灣優秀的運動選手與隊伍在島內勝出者即成為地區性代表隊,順理成章前往日本參加更高層級的比賽。此外,體育是現代教育不可偏廢的項目,不僅能改善個人體格發育,也有助促進健康衛生;同時,體育並非僅是單純的身體運動而已,有時亦被視為國力的象徵,發展體育運動有助陶冶國民性格和促進日臺融合。最後,隨著日本統治的時間漸久以及統治程度的強化,臺灣體育運動呈現日漸普及的趨勢,而另一方面,則漸帶有濃厚的日本色彩,甚至許多日式運動術語發至今仍是使用中的辭彙即是明證。至於日治時期臺灣體育運動的成績表現究竟如何呢?整體而言,不僅與殖民母國日本仍然相去甚遠,即便連同為殖民地的朝鮮、滿洲、菲律賓等地亦有所不及。然而,雖然未見日治時期臺灣運動選手與中國正面交手的紀錄,但從1948年的上海全國運動會成績可推知,日治臺灣體育運動的整體水準,似乎不在同時期的中國之下。 關鍵字:日治時期 臺灣 體育史 體育觀 武德會 體育俱樂部 臺灣體育獎勵會 臺灣體育協會 明治神宮體育大會 甲子園 網球 棒球 田徑 游泳 登山 馬術 高爾夫 / In May 1948, the 7th China Sports Game was held in Shanghai. The athletic performance of male track and field athletes amazed the world by winning the overall championship though it was the debut of Taiwan in this athletic event. These male athletes disciplined themselves, obeyed the rules, cooperated with one another, obeyed the referees’ orders, and exhibited good sportsmanship. Both their athletic performance and sportsmanship on the sports field or beyond sports field were ranked as “national champion” by the sponsor. Their great performance actually was the achievement from the devotion to developing athletic sports during Japanese Occupation Period. In fact, before the colonization of Japan, modern athletic sports in Taiwan were only practiced in few regions where foreigners aggregated and the effect of athletic performance was quite limited. The overall promotion of athletic sports was put into practice through school education and social sports activities until the Japanese Occupation Period and so was the great performance achieved at that time. The main purpose of this study is to investigate why and how the Japanese developed athletic sports in Taiwan and the effects. The research subjects were mainly the athletes at that time in Taiwan, including the Japanese, the Taiwanese, and the aboriginals (indigenous people) since these three groups were all members of sports representatives in Taiwan at that time. These subjects were investigated to find out about the development of athletic sports in Taiwan at that time. Firstly, the study probed into the rise and the development of modern western athletic sports. With the expansion of national powers of European countries and the U.S., their science, technology, and life styles were spread to Asia. Moreover, after Meiji Restoration, the Japanese started to put emphasis on improving their physique and hence learnt the western athletic sports. And Taiwan was colonized by Japan under this background. Secondly, it investigated the concepts and viewpoints on athletic sports proposed from all walks of life during Japanese Occupation Period to demonstrate the motives and purposes of athletic sport development. Thirdly, it investigated the major facilities responsible for promoting athletic sports from the aspects of personnel matters, funds, and the operation methods to understand who were involved, how they developed athletic sports, and under what kind of background were athletic sports developed. Fourthly, it investigated the performance of athletes in each kind of sports games, especially national games. The study also compared the athletic performance of Taiwan with that of nearby countries such as Korea, Manjou, Japan, and Philippine to understand the athletic level of Taiwan. Fifthly, it analyzed the leisure sports that the leaders of the society engaged in to explore the preferences of leisure sports of the rich at that time and further investigate the profile of athletic sports development. This study found that the development of athletic sports in Taiwan during Japanese Occupation Period was dominated by the government with the cooperation of non-government in promotion. The sports organizations in Taiwan were the colonial branches of sports organizations in Japanese Empire and the national sports competitions in Taiwan became local preliminaries of Japanese national competitions. The outstanding athletes in Taiwan and the winners of local preliminaries would become the local sports representatives to participate in competitions of higher level in Japan. In addition, the study found that physical education is indispensable in modern education, which not only improves the physical development of individuals but also improves health. Meanwhile, athletic sports ability not simply teaches a kind of physical movement and it is sometimes viewed as a symbol of national powers. The development of athletic sports helped cultivate the personality of people and improved the integration ethnic integration between Taiwan and Japan. With the increase of colonization time and the reinforcement of governance, the athletic sports in Taiwan gradually became more and more popular. On the other hand, it was found that the sports activities in Taiwan was greatly influenced by Japan and even the Japanese sports vocabularies are still used now in sports activities. As for the athletic performance of Taiwan during Japanese Occupation Period, as a whole, the athletic performance of Taiwan was better than Japan and other colonies of Japan, such as Korea, Manjou, and Philippine. Although the athletes in Taiwan during Japanese Occupation Period did not compete with the athletes of China, it could be inferred from their athletic performance that the overall level of athletic sports in Taiwan during Japanese Occupation Period was equivalent to that of China.
