The problem addressed in this study is the appropriateness of using different pre-training supplementation strategies and their ability to improve training performance and psychological measures. The aim of the study is the evaluation of the effectiveness of a multi-ingredient pre-workout supplement (MIPS) containing beta-alanine, L-citrulline malate, arginine alpha-ketoglutarate, L-taurine, L-tyrosine and caffeine compared to an exact dosage of anhydrous caffeine in bench press strength endurance, feeling scale (FS), felt arousal scale (FAS) and session rating of perceived exertion (sRPE). A group of fifteen resistance-trained males, weighing 83.92 ± 8.95 kg and having an average of 5.6 ± 3.38 years of training experience, tested their bench press 10 repetition maximum (79.01 ± 12.13). In a cross-over manner, they participated in two sessions where they were blinded to the order of supplementation they were given: either a MIPS including caffeine or caffeine alone. They completed the bench press strength endurance test with pre- and post-training psychological assessments containing FS, FAS and sRPE. Bench press repetition volume was greater after anhydrous caffeine than MIPS supplementation with no difference in psychological measures. These results indicate that MIPS supplementation is less ergogenic and cost effective than caffeine alone.

Background: The ergogenic effect is a highly practical and relevant topic in sports research, particularly in strength sports where numerous strategies have gained widespread recognition. Despite reports indicating challenges in the simultaneous use of various ergogenic strategies, our understanding of how they are practically employed is limited. This study aimed to determine and evaluate preferences in the use of nutritional and non-nutritional means of eliciting the ergogenic effect of individuals regularly participating in strength training.Materials and Methods: A total of 108 participants completed an original, online questionary shared on social media sites and created using Google Forms. Significance of differences was determined with Chi-square test.Results: A significant majority of responders declared use of nutritional (90%) and non-nutritional (62%) ergogenic aids, however only insignificant majority declared simultaneously using more than one ergogenic aid (56%). The most popular nutritional means of eliciting the ergogenic effect were caffein, coffee and creatine; non-nutritional were listening to music and dynamic stretching; the most popular combinations of two means of eliciting the ergogenic effect were caffeine with music and caffeine with creatine; and the most popular combinations of three means of eliciting the ergogenic effect were caffeine with creatine and music. Only age of participants influenced preferences in use of ergogenic means, where group 18 – 25 declared using non-nutritional means of eliciting ergogenic effect significantly more frequent.Conclusion: Results of the study indicate that the majority of polish as well as foreign strength trainees employ ergogenic aids, typically favoring well-established options supported by scientific literature.
