Hence, it is plausible to speculate that providing a pink solution during exercise could induce an ergogenic benefit through a potential placebo effect.\n                    <jats:bold>Aim:<\/jats:bold>\n                    We examined whether ingesting a pink non-caloric, artificially sweetened solution can improve endurance strength exercise performance and psychological responses.\n                    <jats:bold>Methods:<\/jats:bold>\n                    Eighteen strength-trained individuals (34\u2009\u00b1\u20097\u2005y; 1.74\u2009\u00b1\u20090.06\u2005m; 79.86\u2009\u00b1\u200910.91\u2005kg) completed three experimental trials in a randomized, single-blind, crossover counterbalanced fashion. In each trial, participants performed a 5-set strength endurance test at 70% of the one-repetition maximum in the bench press exercise, interspersed by 2\u2005min. Before each set, participants ingested either a pink (PINK) or a transparent (TRANSP) non-caloric, artificially sweetened solution. A session without ingestion (CON) was also completed. Total number of repetitions and psychological responses such as motivation, emotional arousal, affect, and ratings of perceived exertion were obtained throughout the exercise protocol.\n                    <jats:bold>Results:<\/jats:bold>\n                    Total repetitions improved in PINK (60\u2009\u00b1\u200912 reps) compared to TRANSP (\n                    <jats:italic>p\u2009<\/jats:italic>\n                    =\u20090.03; 56\u2009\u00b1\u200910 reps; ES\u2009=\u20090.22; \u00b13.8%) and CON (\n                    <jats:italic>p\u2009<\/jats:italic>\n                    =\u20090.01; 56\u2009\u00b1\u20099 reps; ES\u2009=\u20090.33; \u00b16.6%), but no difference occurred between TRANSP and CON (\n                    <jats:italic>p\u2009<\/jats:italic>\n                    =\u20090.84; ES\u2009=\u20090.12; \u00b12.4%).
