Multi-ingredient pre-workout supplements (MIPSs) contain a blend of ingredients, such as caffeine (CAF), beta-alanine (BA), creatine, taurine, nitric oxide agents, and amino acids, as well as herbs and botanicals, formulated to enhance metabolic, physiological, and psychological function during exercise.
According to the authors of the current study, most studies examining the effectiveness of MIPSs have focused on measures of strength and power, indices of anaerobic exercise performance, and their effect on subjective mood, energy, and focus. The collective findings suggest that MIPSs are more effective at improving muscular endurance compared to maximal effort anaerobic performance.
And while a few studies have examined the effectiveness of MIPSs on endurance exercise performance, they have reported conflicting results and did not investigate competitive or highly trained endurance athletes.
PerformElite (MIPS-PE, EndurElite, USA) is a relatively new MIPS product specifically formulated for endurance athletes. Like other MIPSs, it contains CAF, BA, taurine, and beetroot, as well as a proprietary blend of mushrooms (PeakO2) and apple and ancient peat polyphenols (elevATP). Together, these ingredients are purported to enhance energy, buffer lactic acid, improve mental focus, reduce perceived effort, and delay the onset of fatigue.
The aim of the current study was to examine the effect of MIPS-PE on: TTF, heart rate (HR), rating of perceived exertion (RPE), and blood lactate concentrations in elite cross-country athletes.The research team conducted a randomized, double-blind, placebo-controlled cross-over study, using a sample of eleven NCAA Division I cross-country athletes (6 male and 5 female, aged 20 ± 2).
