L-KARNİTİN ALIMININ 1500m KOŞU PERFORMANSINA ETKİSİ

Year 2002, Volume: 7 Issue: 4, 15 - 22, 10.10.2002

Abstract

Bu çalışma, akut L-karnitin
ilavesinin 1500m koşu performansı üzerindeki etkisini araştırmak amacıyla
gerçek-leştirilmiştir. Çalışmaya, yaş, boy ve vücut ağırlığı ortalamaları
sırasıyla 21,35±1,4 yıl, 176,55±6,8 cm, 70,75±4,9 kg olan, antrenmanlı ve
sağlıklı 20 sporcu gönüllü olarak katılmışlardır. Denekler tesadüfi yöntemle
Plasebo ve Karnitin olmak üzere iki grupta sınışandırıldılar. Çalışmadan bir
hafta önce deneklerin bazı fiziki ve fizyolojik parametreleri belirlenmiştir.

 

Çalışma ön ve son test
olmak üzere iki aşamada gerçekleştirildi. Denekler, her iki aşamada da 1500m
koştular ve performans zamanları kaydedildi. Her iki testin bitimini takip eden
birinci dakika içerisinde kalp atım sayıları alındı. Son testten 90 dk önce
Karnitin grubu, içerisinde 2 gr L-Karnitin bulunan meyve suyu içerken Plasebo
grubu sadece meyve suyu içmiştir.

 

İki grubun ön ve son test
sonrası kalp atım sayıları ortalamaları arasında anlamlı bir fark
bulunamamıştır. 1500m dereceleri arasında, ön test değerlerinde önemli bir
farlılık olmazken Deney grubunun son test değerleri hem kontrol hem de kendi ön
test değerlerine oranla anlamlı bir değişim göstermiştir (P<0.001).

THE EFFECT OF L-CARNITINE INTAKE ON 15OOm RUNNING PERFORMANCE

Year 2002, Volume: 7 Issue: 4, 15 - 22, 10.10.2002

Abstract

The purpose of this investigation was to determine the effects of acute L-Carnitine supplementation on 1500m

running performance. Healthy and well-trained twenty voluntary male athletes participated in this investigation.

Subjects’ age, height and weight 21,35±1,4 year, 176,55±6,8 cm, 70,75±4,9 kg, respectively. Subjects were

randomly classified in two groups as a Placebo (n=10) and Carnitine (n=10). Subjects’ some physical and

physiological parameters were determined before a week from firs test.

This investigation was performed in two trials as first and last tests. Subjects ran 1500m at each trial and their performance times were recorded. Heart rate was recorded in the first minute at the end of each trial. The Carnitine group received 2gr L-Carnitine in a citrus drink before 90 minutes from the last test while the Placebo group received only the citrus drink at the same time.

There was no significant difference between the heart rates of two groups. Although there were no differences between 1500m performance times measured of both tests in both groups. The performance time of Carnitine group was found significantly higher than the Placebo group after the last test (P<0.001)
