Effect of acute babassu mesocarp flour supplementation (ORBIGNYA PHALERATA MART.) on aerobic capacity, oxidative stress, and muscle damage in recreational runners: A randomized, crossover, placebo-controlled study

This study aimed to evaluate the effects of acute babassu mesocarp flour (BM) supplementation on aerobic capacity, oxidative stress, and muscle damage in recreational runners. 14 men (26,4±8,3 years) were randomly assigned and ingested one single dose of (BM) and maltodextrin (PLA) supplements and performed the 3200m running test. There was a 7-days washout period between each supplementation. Biochemical parameters such as serum glucose, malondialdehyde, creatine kinase, and lactate dehydrogenase were evaluated. There were no differences between the conditions for the time-trial performance (BM=12.3±1.5 vs PLA=12.2±1.3 s, t=1.743, p=0.612, d=0.10) and maximum heart rate (BM=106.7±9.8 vs PLA=111.6±15.3 bpm, t=-1.286, p=0.221, d=0.36). There was an increase in glucose, creatine kinase, lactate dehydrogenase, and malondialdehyde (p<0.001, η2<0.96) in both procedures. However, there was no condition x time interaction (p=0.469, η2=0.04). Babassu mesocarp flour supplementation did not alter aerobic capacity, serum glucose, oxidative stress and muscle damage markers in recreational runners.
