The purpose of this study is to determine the effect of caffeine on muscle strength among sports science student through pre-test and post-test experimental design. All subjects are healthy males aged between 18 to 25 years old and exercise regularly with resistance training was volunteer to participate. The study compared the differences between caffeine and placebo of 1RM bench press (BP) and back squat (BS). Paired T test was used as this study included pre-test and post-test. During pre-test, all subjects performed two test which is 1RM BP and BS without any supplement, after result collected, randomized sampling technique was used to divide into two group whether experimental group (CAF) and control group (PLA). After a week, they were perform the bench press and back squat by consumed caffeine and placebo. Based on paired T test result, there was no significant difference between CAF and PLA group of 1RM of BP and BS. The overall result is CAF group BP (p=0.11) and BS (p=0.07), PLA group BP (p=0.44) and BS (p=0.14). As a conclusion, this finding suggests caffeine does not effect on muscle strength among sports science student. Further studies may consider to increase the number of participant especially among experiences resistance trained man that involve several of year in strength training.
