Dopaj in sport

Dopajul in sport

O prima actiune concentrate la nivel european o reprezinta colocviul de la Ouriage - les - Bains din Franta cu care ocazie se da o prima definitie dopajului (folosirea unor substante straine organismului, care pot adduce prejudiciu starii de sanatate si eticii sportive) si se stabileste o prima lista de substante dopante, care in principal cuprind: amphetamine si derivate antidepresive, analeptice cardio - respiratorii, alcaloizi excitanti ai sistemului nervos (exemplu: stricina, etc.).

Dar dorinta celor interesati sa-si creasca performantele sportive pe cai artificiale apeleaza la alte droguri. Prin anii 1960 apare o noua clasa, steroizii anabolizanti (derivati de testosteron) a carei prima utilizare s-ar parea sa fi avut loc in SUA cu punct de plecare culturistii.

La inceput tehnologiile de depistare erau ineficiente (gazcromatografia, cromatografia in faza lichida, etc.). Abia dupa aparitia primelor laboratoare dotate cu sistemul gazocromatografe - spectrometru de masa (Koln ...

Aspecte privind eficientizarea antrenamentelor de culturism

Cu ajutorul "gimnasticii de casa", ce evidentiaza efectuarea unor serii de exercitii cu caracter analitic folosind haltere, gantere, sau un aparat din cauciuc care permite contractii si extinderi, se rezolva atat problema dezvoltarii armonioase a organelor interne cat si buna lor functionare si nu in ultimul rand prevenirea atrofiei musculare.
Acest sistem de cultura fizica a fost practicat si propagat in Franta in a doua jumatate a secolului XIX de catre Triat (1812-1881), atragand un numar mare de intelectuali.

Dopajul in sport

De aici si pana la trecerea in sport nu a fost decat un pas. Postbelic, cand viata sportiva si-a reluat cursul a aparut si utilizarea substantelor dopante, amfetaminele, antidepresivele, simpaticomimeticele si analgezicele cardio – respiratorii fiind primele grupe de substante folosite de sportivi din proprie initiativa sau la recomandarea unor cadre sportive (antrenori, medici, masori, etc.).

In vremea aceea regulamentele anti – doping erau inexistente iar lipsa unor laboratoare de specialitate facilita aceasta actiune (dopaj), in mod nestintific si plina de riscuri. Cine nu-si aminteste de ciclistul danez Olsem, care la Jocurile Olimpice de la Roma din 1960 concurand in proba 100 km sosea echipe, pe o caldura inabusitoare de 33° C isi pierde viata iar la necropsie se evidentiaza urme de anfetamine in corpul sau.

Extreme Sport Climbing

In the X Games, speed climbing is done on a 60-foot, vertical wall. The difficulty climb uses a 40-foot wall with a 20-foot overhang. Bouldering is a recent offshoot. Originally, climbers worked on boulders to practice a particular move, and bouldering has now become a discipline in itself. As the name suggests, the sport involves climbing a single large rock with no ropes or other mechanical aids.

American football

Football is played by two opposing teams, each fielding 11 players. Each team tries to move the ball down the field to score in the end zone defended by its opponents. During a football game the teams are designated as the offensive team (the team in possession of the ball) and the defensive team (the team defending a goal line against the offensive team). Players involved in kicking situations are known as the special teams. The 11 players of the offensive team are divided into two groups. To protect themselves from the often violent bodily contact that characterizes football, players wear elaborate equipment, including lightweight plasticized padding covering the thighs, hips, shoulders, knees, and often the forearms and hands. Players also wear plastic helmets with guards that cover most of the face. American football was made popular by teams representing colleges and universities. These teams dominated the game for most of the first 100 years of football in the United ...

The Olympic Games

Coubertin wanted the Olympic Games to feature both ancient and modern sports. The discus event, for instance, symbolized continuity with the past, because the ancient Greeks had practiced the sport. Bicycle races, on the other hand, which were a more recent sporting innovation, represented modernity. The marathon race was meant to commemorate the distance from the town of Marathon to Athens run by a Greek soldier in 490 BC to announce a Greek victory over the invading Persians, which was slightly less than the current marathon distance of 42.2 km . (The longest race of the ancient Olympics was about 1000 m) .

Instability in the Greek government threatened preparations for the 1896 Games, but Coubertin traveled to Athens and enlisted support from the Greek royal family to help organize the event. The program for the 1896 Games, comprising only summer events (the Winter Olympics were not established until 1924), included about 300 athletes from fewer than 15 countries competing ...
