Supplementation with an Antioxidant Rich Oil Does Not Influence Blood Lactate, Rate of Perceived Exertion and Muscle Soreness after Resistance Exercise

Abstract

Pequi (Caryocar brasiliense) is a fruit from Brazil with antioxidant properties. Previous research suggested that it could be a candidate for sports ergogenic aid. However, little is known about pequi supplementation and sports performance. Aim: to analyze the effect of pequi oil supplementation on blood lactate, rate of perceived exertion and muscle soreness after a resistance exercise session. Twelve men (21.1±2.6 years, 77.0±10.5 kg, 24.3±1.9 Kg/m²) underwent pequi supplementation for 14 days. Before and after supplementation they performed an exercise session in the chest press. Lactate, rate of perceived exertion and muscle soreness were measured. No significant difference was found after the supplementation (P>.05).Pequi oil supplementation has no influence on blood lactate concentration, rate of perceived exertion and muscle soreness during resistance exercise.

“…However, the present investigation did not corroborate those studies, as no effect of the supplementation was observed in any of the dependent variables both within and between groups. Interestingly, this is consistent with previous studies that analyzed young, healthy, and physically active people after 14 and 30 days of supplementation combined with resistance exercise and did not show any effect of the supplementation in acute and chronic SBP, DBP, HR, DP, as well as total cholesterol, triglycerides, and acute blood lactate, rate of perceived exertion and 24-hour muscle soreness (CLAEL et al, 2020;DUTRA et al, 2019;LEITE et al, 2020).…”
