| Popis: | Curcumin may improve athletic performance through a reduction in inflammation following exercise and improve mental states of well-being. The purpose of this investigation was to explore the effects of a 14 day HIIT intervention and oral supplementation with Longvida® optimized curcumin on athletic performance, lactate response, and well-being. Sixteen males and twenty females participated in a double-blinded, randomized, placebo-controlled trial to explore the effects of Longvida(R) optimized curcumin (1.0 g/day) and or a placebo (PLA) taken daily during a 14 day HIIT protocol. Participants were randomized into two groups, then evaluated in three groups, curcumin-fast (CURF), curcumin-slow (CURS) and placebo. Curcumin-fast and curcumin-slow were separated by their 16.1 km cycling time trial performance (TT) with CURF and CURS determined by a TT 30 min at the pre intervention time point, respectively. Cycling time-trial performance, blood lactate response, and well-being assessments were determined at pre and post 14 day HIIT intervention time points. Blood lactate was recorded at baseline, 8.01 km, 15.1 km, and 1 min post, and 4 min post of the pre and post intervention TT. Following the internvetion, CONP and CURS experienced with 8.15% and 5.04% improvements in TT performance times, while CURF experienced a 0.57% improvement in TT performance time. No changes were observed with respect to other measures. When curcumin is taken daily in conjunction with 14 days of HIIT on a cycle ergometer, cycling performance in either well trained or more recreationally trained athletes is not impaired. Although the improvements in TT performance were not stasticially significant, they are noteworthy. |
