Bottom Line: The MVM + G combination also led to significantly increased accuracy of numeric working memory and increased speed of picture recognition, compared to the placebo.There were no significant effects of supplementation on any other cognitive or mood measures or on substrate metabolism during exercise.These findings demonstrate that consuming a vitamin and mineral complex containing guaraná, prior to exercise, can positively impact subsequent memory performance and reduce perceived exertion during a moderate-intensity run in active males.

ABSTRACT
Exercise undertaken in a fasted state can lead to higher post-exercise mental fatigue. The administration of a vitamin and mineral complex with guaraná (MVM + G) has been shown to attenuate mental fatigue and improve performance during cognitively demanding tasks. This placebo-controlled, double-blind, randomized, balanced cross-over study examined the effect of MVM + G consumed prior to morning exercise on cognitive performance, affect, exertion, and substrate metabolism. Forty active males (age 21.4 ± 3.0 year; body mass index (BMI) 24.0 ± 2.4 kg/m2; maximal oxygen consumption (V̇O2max) 57.6 ± 7.3 mL/min/kg) completed two main trials, consuming either MVM + G or placebo prior to a 30-min run at 60% V̇O2max. Supplementation prior to exercise led to a small but significant reduction in Rating of Perceived Exertion (RPE) during exercise compared to the placebo. The MVM + G combination also led to significantly increased accuracy of numeric working memory and increased speed of picture recognition, compared to the placebo. There were no significant effects of supplementation on any other cognitive or mood measures or on substrate metabolism during exercise. These findings demonstrate that consuming a vitamin and mineral complex containing guaraná, prior to exercise, can positively impact subsequent memory performance and reduce perceived exertion during a moderate-intensity run in active males.

nutrients-07-05272-f001: Overview of study trial days (Visit 3 and 4).

Mentions: Following baseline cognitive and mood measurements, participants were provided with the intervention and then rested for 30 min in the laboratory. After 30 min, cognitive and mood measures were repeated before participants completed a 30-min run at 60% V̇O2max. This was immediately followed by completion of the cognitive tasks and mood assessments. Participants then rested in the laboratory for the following 60 min before completing a final assessment of cognitive performance and mood. ICa was measured continuously throughout the exercise period. RPE, FAS, and FS ratings were recorded at 10 min intervals throughout exercise and FAS and FS at 45 and 75 min post-exercise also. Each battery of cognitive tasks and mood scales took ~18 min to complete. During rest periods, participants remained in the laboratory and watched a video provided by the researcher. Water intake was recorded during Visit 3 and consumption of the same amount was encouraged at Visit 4. An overview of the study trial days is presented in Figure 1.
