Abstract:   (573 Views)

In order to compare the acute effects of OR and Megabasic (two energy drinks)
by a placebo, 24 volunteer male athletes (age: 24.3±2.03 yrs, height
173.56±7.02cm and weight 75.43±3.07kg) participated in two consecutive
RAST tests by 40 min rest interval in between within 3 randomly divided groups.
There were six times blood sampling (before and also 2 and 4 min after than
both tests) in order to analyze blood lactate and PH levels (Gas analyzer) and
also the anaerobic indices (Peak, mean and mean power) was calculated. The
data corresponding to each group’s blood factors was compared by ANOVA for
repeated measurements (post hoc: Bonferoni), their changes between two
consecutive RAST tests was compared by ANOVA (post hoc: LSD) and
anaerobic power data for each group was compared using pair sample t test at
0.05 significance level. Results: Significant changes were observed in blood
lactate and PH levels during repeated measurements in both RAST tests at all
groups (p<0.05). There were also significant differences in the amount of the
changes in between the measurements between groups (p<0.05). Additionally,
Peak and min power only significantly increased in second RAST test rather
than first one and mean power also significantly decreased in both energy drink
groups between the first and second RAST tests (p<0.05). Conclusions:
Consumption of the OR can affect anaerobic power during short term repeated
interval activities. However, there are evident differences in between multiple
brands of energy drinks with regard to the amount of the modifications in the
changes at both blood lactate and PH levels, in spite of this fact that there is
any consensus in this field because of the lack of comprehensive researches.
