| Abstract | Background: Badminton involves repeated high-intensity efforts that may increase reactive oxygen species production and lipid peroxidation during recovery. Malondialdehyde (MDA) is commonly used as a marker of lipid peroxidation. Curcumin has been investigated as a nutritional intervention for exercise-induced oxidative stress; however, evidence in badminton athletes after acute high-intensity interval training (HIIT) remains limited. Objectives: This study aimed to compare changes in plasma MDA levels between the curcumin and placebo groups during the 24-hour recovery period following acute ergocycle HIIT in male badminton athletes. Methods: This quasi-experimental pretest–posttest control-group study was conducted at the Physiology Laboratory, Universitas Brawijaya, from August to September 2025. Thirteen male badminton athletes or students aged 18 - 25 years with a normal Body Mass Index completed the protocol and were allocated to the curcumin group (500 mg without piperine; n = 6) or the placebo group (n = 7). After a 12-hour fast, participants completed a single 20-minute ergocycle HIIT session at approximately 90% of maximal heart rate, consisting of repeated 10-second bouts at 100 rpm followed by 50 seconds of active recovery at 45 - 55 rpm. The first blood sample (T1) was collected immediately after HIIT and before capsule ingestion. The second sample (T2) was collected 24 hours after supplementation, following an approximately 10-hour fast. Plasma MDA was measured using a commercial assay kit. Between-group differences at T2 were analyzed using an analysis of covariance adjusted for T1 MDA. Results: Plasma MDA increased from T1 to T2 in both groups. In the curcumin group, MDA increased from 0.65 ± 0.13 to 1.16 ± 0.44 nmol/mL, whereas in the placebo group, it increased from 1.03 ± 0.58 to 1.37 ± 0.47 nmol/mL. No significant between-group difference in the change was observed, and the Time × Group interaction was not significant (P = 0.163). In an additional baseline-adjusted analysis, the Group × T1 MDA term was significant (P = 0.001), indicating that the baseline-to-follow-up relationship differed between groups and that standard analysis of covariance without an interaction term was inappropriate for primary inference. Conclusions: In this preliminary sample, a single 500 mg dose of curcumin did not produce a consistent between-group effect on the 24-hour plasma MDA response. The baseline-adjusted sensitivity analysis suggested that the association between baseline and follow-up MDA differed by group, indicating substantial uncertainty in baseline-adjusted between-group comparisons. Further studies with larger samples, repeated dosing, a pre-exercise baseline assessment, and additional recovery time points are warranted. | en |
