Abstract
Background: Different herbal supplements have been studied by many researchers to improve athletic performance and prevent or at least delay fatigue. The aim of this study was to determine the influence of acute thyme hydro-extract supplementation on performance of 200 and 400-meter running of young males.
Methods:After signing a written consent,a total number of 20 volunteersubjects(age: 21±2.62 years, height: 177.38±6.23 cm, weight: 70.72±12.56 kg)were divided randomlyeither into one of two groups considering their pre-test performance to fulfill the homogeneity of groups. After one week, they received 200 ml flavored and colored tap water (placebo group: n = 10) or thyme hydro- extract (experimental group: n = 10) 30 minutes before 200 and 400-meter running tests. At the first, participants completed 200-meter running test individually. 10 minutes after the end of first test, subjects tried 400-meter running test. The time needed to complete determined distances recorded by the researchers using a stopwatch. By the way, the rate of perceived exertion was controlled by Borg scale.Statistical analysis was performed using 23rdversion of SPSS softwareat the significance level of 0.5 withpairedsamples t-test.
Results: Findings revealed thatthyme hydro-extract supplementation couldn’t significantly improve the performance of 200-meter dash compared to the placebo group (t8=-2.27, P= 0.053; t8=-3.51, P= 0.008, experimental and placebo group respectively).But interestingly, acute thyme supplementation did significantly improve 400-meter running performance (about 4 seconds) (t8=2.5, P= 0.037; t8=0.482, P=
0.643, experimental and placebo group respectively). Also, there was not a significant difference in the rate of perceived exertion betweentwo groups on both tests.
Conclusions: like the previous animal studies, it seems that we can use this supplement to improve athletic performance even by acute intake and in intense exercises. Different underlying mechanisms can be responsible to these findings. Adenosine A1 receptor, hippocampus serotonin and dopaminelevelsand even elevated myofibrillar sensitivity to Ca2+might be candidate mechanisms.Even though, further studies are necessary to understand the mechanisms involved in the presence of thyme extract to improve
endurance performance.
