Effects of acute pre-exercise glicerol suplementation on lactate and maxvo

Araştırmada akut egzersiz öncesi uygulanan gliserol takviyesinin sporcularda ve sedanter bireylerde MaxVO2 ve Laktat üzerine etkisinin incelenmesi amaçlanmıştır. Yaş ortalamaları 18.20±0.6110 yıl, boy ortalamaları 178.20±1.7814 cm ve vücut ağırlığı ortalamaları 65.17±2.0488 kg olan elit düzeyde atletizm branşı ile uğraşan 10 sağlıklı erkek sporcu ve yaş ortalamaları 19.70±0.4726 yıl, boy ortalamaları 169,10±2.2184 cm ve vücut ağırlığı ortalamaları 71.09±1.8713 kg olan değişik meslek gruplarından 10 sağlıklı erkek sedanter olmak üzere toplam 20 kişi denek olarak kullanıldı. Her iki gruba 1. gün shuttle run testi öncesi ve hemen sonrası laktat ölçümü için kulak memesinden, kan örnekleri alındı. 2. gün aynı egzersiz testinde 2 saat önce 1 gr/kg gliserol su ile karıştırılarak solisyon halinde her iki gruba verildi ve shuttle run testi uygulandı. Ayrıca her iki gün uygulanan test sonrası her iki grubun MaxVO2 düzeyleri belirlendi. Elde edilecen verilerin istatistiki analizlerin yapılmasında SPSS paket programı kullanıldı. Tüm deneklerin ölçülen parametrelerinin ortalama değerleri ve standart hataları hesaplandı.İki grup arası farklılıkların tespitinde indepented (bağımsız) “t” testi kullanıldı. Grup içi farklılıkların tespitinde ise paired (bağımlı) “t” testi kullanıldı. Analizler sonucunda; K ve S (Kontrol,Sporcu) grubunun ES (egzersiz sonrası), MaxVO2 düzeyi TES (takviyeli egzersiz sonrası) dan önemli (p

Sporcularda ve sedanter bireylerde akut egzersiz öncesi gliserol takviyesinin laktat ve MaxVO2 üzerine etkileri

This study aims to investigate the effects of acute pre-exercise glycerol loading (GL) on including lactate and maximum aerobic power. In this study, 10 healthy elite athletes with a mean age of 18.20±0.61 years, with a mean body height of 178.20±1.78 cms, with a mean body weight of 65.17±2.049 kgs and 10 healthy sedentars from different profession groups with a mean age of 19.70±0.47 years, with a mean body height of 169,10±2.22 cms and with a mean body weight of 71.09±1.87 kgs, totally 20 males were used as subjects. On the first day of the research, blood samples were taken from ear lobe for lactate measurement and from analysis before the shuttle run test. On the second day, after loading 1gr/kg-1 glycerol mixed with water to the subjects two hours before testing, max VO2 was determined by using shuttle run test in both groups. Statistical analyzes were conducted by SPSS. Mean values of standard deviations were calculated. The independent t-tests were used to determine the differences between two groups. Also, paired t-tests were performed to determine the differences within groups. Results of this study indicated that max VO2 of experiment and control groups were found higher after loading at 0.05 significance level. Max VO2 of experiment group was significantly higher than controls. Lactate levels were increased after exercise and GL (p<0.05). Control group had a significantly higher lactate level than experiment group but there was no statistical significant difference between two groups after glycerol loading. As a result, there is a significant effect of acute pre-exercise glycerol loading on maximum aerobic power whereas no significant effect on the lactate may be partly due to the amount of glycerol and the time of loading.
