Shahid Beheshti University Journal of Sport and Exercise Physiology 2676-3710 5 1 2012 04 20 The acute effect of caffeine and ibuprofen on RPE, RM, PPI at resistance exercise in male athletes The acute effect of caffeine and ibuprofen on RPE, RM, PPI at resistance exercise in male athletes 98638 10.48308/joeppa.2012.98638 FA Journal Article 2015 05 17 <br />Purpose: This study compared independent effects of caffeine and Ibuprofen on perceived exertion<br />(RPE), perceived pain index (PPI), maximum repetitions (RM) and heart rate (HR) during resistance<br />training bouts. Method: Fifteen male students (Age: 26±2 yr.) participated in a double-blind<br />study with three independent, counterbalanced sessions where in Ibuprofen (400 mg), caffeine (6<br />mg.kg-1), or matched placebo were ingested 1 hour before exercise, and RPE, PPI, RM and HR<br />(per set) were recorded in individuals, predetermined, 12-repetition maximum for leg extensions<br />(LE), leg flexion (LF), bench press (BP) and arm flexion (AF). Analyses of variance (ANOVA)<br />with repeated measures were used for between-trial comparisons. Results: Caffeine resulted in<br />significantly greater (p < 0.05) HR (LE and BP) and RM (LE, LF, BP, AF) and resulted in<br />significantly lower (p < 0.05) RPE (LF, BP, AF) and PPI (LF, BP, AF) compared with Ibuprofen<br />and placebo. Ibuprofen resulted just in significantly higher PPI in LE(p < 0.05). Conclusion: this<br />study demonstrates that caffeine significantly enhanced resistance training performance, whereas<br />Ibuprofen did not. Athletes may improve their resistance training performance by acute ingestion<br />of caffeine.<br /><br /> <br />Purpose: This study compared independent effects of caffeine and Ibuprofen on perceived exertion<br />(RPE), perceived pain index (PPI), maximum repetitions (RM) and heart rate (HR) during resistance<br />training bouts.
