| dc.description.abstract | Coffee can be classified as a psicostimulant agent cause awakening, due to its content, such as
caffeine. For intolerant person caffeine can be harmful, so nowadays created decaffeinated
coffee. The purpose of this study was to determine the effect of decaffeinated coffee drink
consumption on VO
2
max and pulse recovery rate after treadmill test. This was a quasi
experimental study with Randomized Clinical Trial (RCT) methods. There were 20 volunteers,
divided into two groups that swapping roles after 4 days washing out. The control group was
given an instant coffee drink while the treatment group was given a decaffeinated coffee drink. All
volunteers were asked to perform Modified Bruce Treadmill Test procedure until exhausted then
VO
2
max were examined. The results showed the average value of VO
2
max in treatment group
was +45,22 ml/kg/min and in control group +46,96 ml/kg/min from the previous study the value of
max using placebo was 25,98 ml/kg/min. Duration of pulse recovery rate in treatment group
was 52 minutes faster than control group, 57 minutes. Analyses by T-test obtained p=0,23 mean
there was no significant difference. In conclusion, decaffeinated coffee drinks could increased
VO
2
VO
2
max as the instant coffee did, but it still could accelerate pulse recovery rate.
