چکیده
Yüzme sporunda santisaniye gibi saniyeden daha küçük zaman aral???nda performans de?erlendirilerek yüzücünün en k?sa sürede mesafeyi tamamlamas? amaçlanmaktad?r. Ç?k??, stil yüzme, dönme ve bitirme a?amalar?nda; ç?k?? a?amas?n?n performans? di?er a?amalara etki ederek sporcunun skorunda önemli de?i?ikliklere neden olmaktad?r. Özellikle mesafeli olimpiyat yar??lar?ndaki sporcular?n analizlerinde ilk 15 m’lik skoru büyük oranda etkiledi?i madalya kazan? de?i?tirdi?i görülmü?tür. Performans? art?rmak için biyomekani?inin üç a?amas? olan blok, uçu? su alt?n? etkileyen kuvvetler ayr? öneme sahiptir. Blok a?amas?nda üretilen momentin ileriye gitmesini sa?layarak sualt? erken geçi? ile sporcu az dalga türbülans kuvvetine maruz kalmaktad?r. Böylelikle mesafede h?z bak?m?ndan avantaj yüzme a?amas?na h?zl? geçmektedir. Yüzücünün performans?n? biyomekani?inde; reaksiyon zaman?, blokta olu?turulan itme kuvveti, a?amas?ndaki vücudun stabilitesi, suya giri? s?ras?nda yüzey gerilim sualt?nda sürtünme sürükleme kuvveti birçok çal??mada ele al?nd??? bas?nç fark? kuvvetinin ise biyomekanik analizini yapmak spor bran?lar?na göre (karada yap?lanlara göre) zor oldu?u literatürde yer almaktad?r. Bu nedenle tüm parametreleri içeren çal??malar yerine birkaç parametreyi de?erlendiren bulunmaktad?r. çal??man?n amac? a?amalar?n kendi içinde dinamiklerinin bütün bir çerçevede al?nmas? geli?tirmede bak?? aç?s? olu?turmakt?r.

Overuse Injuries in Sport: a Biomechanical Approach
Sporting injuries may be generally divided into those caused by an impact, where there is a sudden increase in the force applied to the body (an inappropriate landing in Australian football or rugby) or those produced through overuse. Overuse injuries are generally due to overload or repetitive microtrauma of the musculoskeletal system, where a number of repetitive forces each lower than the cr...
متن کاملBiomechanical comparison of the track start and the modified one-handed track start in competitive swimming: an intervention study.
This study compared the conventional track and a new one-handed track start in elite age group swimmers to determine if the new technique had biomechanical implications on dive performance. Five male and seven female GB national qualifiers participated (mean +/- SD: age 16.7 +/- 1.9 years, stretched stature 1.76 +/- 0.8 m, body mass 67.4 +/- 7.9 kg) and were assigned to a control group (n = 6) ...

متن کاملThe Backstroke Swimming Start: State of the Art
As sprint swimming events can be decided by margins as small as .01 s, thus, an effective start is essential. This study reviews and discusses the 'state of the art' literature regarding backstroke start biomechanics from 23 documents. These included two swimming specific publications, eight peer-reviewed journal articles, three from the Biomechanics and Medicine in Swimming Congress series, ei...
