Abstract
Rationale: How caffeine (CAF) intake and warm-up music combination affect male taekwondo athletes' performance during simulated combat is yet unstudied.
Objective: This study examined the potential synergistic effects of low dose of CAF and warm-up music on subsequent taekwondo combat outcomes.
Methods: In a double-blinded, randomized, crossover study, 16 male taekwondo athletes performed simulated combats under six conditions: (a) control, (b) CAF without music (CAF + NM), (c) placebo without music (PL + NM), (d) CAF with music (CAF + M), (e) PL with music (PL + M), and (f) no supplement with music (NS + M). After warming-up, athletes rated their felt arousal (FAS). Perceived exertion (RPE), feeling scale (FS), FAS, and physical enjoyment (PACES) were determined after combat while mean (HRmean) and peak (HRpeak) heart rate were determined for each bout. Each combat was analyzed to determine time-motion aspects and technical-tactical skills.
Results: CAF + M shortened skip and pause times than CAF and music in single-use (p < 0.05), while extend attack time than other conditions (p < 0.001). Additionally, CAF + M increased attacks and defensive actions above that of single treatment conditions (all p < 0.05). Moreover, CAF + M improved FS and FAS post-combat than the other conditions (p < 0.001) and PACES compared to NS + M, PL + NM and PL + M conditions (p < 0.05). Similarly, CAF + M reduced HRmean and HRpeak than the other conditions (p < 0.05).
Conclusion: Combining low dose of CAF and warm-up music could be an effective strategy to enhance taekwondo combat performance in male athletes.

Official Journal of the European Behavioural Pharmacology Society (EBPS)
Psychopharmacology is an international journal that covers the broad topic of elucidating mechanisms by which drugs affect behavior. The scope of the journal encompasses the following fields:
Human Psychopharmacology: Experimental
This section includes manuscripts describing the effects of drugs on mood, behavior, cognition and physiology in humans. The journal encourages submissions that involve brain imaging, genetics, neuroendocrinology, and developmental topics. Usually manuscripts in this section describe studies conducted under controlled conditions, but occasionally descriptive or observational studies are also considered.
Human Psychopharmacology: Clinical and Translational
This section comprises studies addressing the broad intersection of drugs and psychiatric illness. This includes not only clinical trials and studies of drug usage and metabolism, drug surveillance, and pharmacoepidemiology, but also work utilizing the entire range of clinically relevant methodologies, including neuroimaging, pharmacogenetics, cognitive science, biomarkers, and others. Work directed toward the translation of preclinical to clinical knowledge is especially encouraged. The key feature of submissions to this section is that they involve a focus on clinical aspects.
Preclinical psychopharmacology: Behavioral and Neural
This section considers reports on the effects of compounds with defined chemical structures on any aspect of behavior, in particular when correlated with neurochemical effects, in species other than humans. Manuscripts containing neuroscientific techniques in combination with behavior are welcome. We encourage reports of studies that provide insight into the mechanisms of drug action, at the behavioral and molecular levels.
Preclinical Psychopharmacology: Translational
This section considers manuscripts that enhance the confidence in a central mechanism that could be of therapeutic value for psychiatric or neurological patients, using disease-relevant preclinical models and tests, or that report on preclinical manipulations and challenges that have the potential to be translated to the clinic. Studies aiming at the refinement of preclinical models based upon clinical findings (back-translation) will also be considered. The journal particularly encourages submissions that integrate measures of target tissue exposure, activity on the molecular target and/or modulation of the targeted biochemical pathways.
Preclinical Psychopharmacology: Molecular, Genetic and Epigenetic
This section focuses on the molecular and cellular actions of neuropharmacological agents / drugs, and the identification / validation of drug targets affecting the CNS in health and disease. We particularly encourage studies that provide insight into the mechanisms of drug action at the molecular level. Manuscripts containing evidence for genetic or epigenetic effects on neurochemistry or behavior are welcome.
