Background: The impact of oxidative stress (OS) on exercise performance and recovery depends the mode, intensity, duration physical activity, which can lead to inflammation, fatigue, muscle dysfunction. effects carbohydrate (CHO) protein (PRO) supplementation, as well their combination (CHO-PRO), remain controversial, particularly under normal hot environmental conditions. Objectives: present study examined influence locally based isocaloric supplements damage biomarkers during cycling in heat (31°C, 70% relative humidity), compared a placebo (PL). Methods: Sago (Sa), Soy (So), Sago+Soy (SS) were used (CHO), (PRO), CHO-PRO supplements, respectively. Sa, So, SS contained 7.5% 6.0% Sa+1.5% Twelve well-trained male cyclists (age: 19.0 ± 5.6 years, height: 170.8 7.6 cm, body weight: 60.1 11.2 kg, VO2max: 56.5 6.5 mL·kg⁻¹·min⁻¹) participated four experimental trials. Each trial involved 90 minutes steady-state an ergometer at 60% VO2max, followed by 20-km exhaustive time-trial performance. During cycling, participants received five times 0, 20, 40, 60, 80 minutes. Results: Plasma concentrations creatine kinase F2-isoprostanes, are (OS), significantly decreased after trials (P < 0.05). reduction these group indicated that supplementation did not provide additional benefits, exhibited similar effects. Conclusions: In conclusion, despite unexpected results, endurance athletes exercising humid conditions may potentially reduce symptoms consuming greater amounts supplements.
