The aim of this study is to assess the antioxidant capacity of two mango base beverages (AM1, AM2), against exercise-induced oxidative stress.
Introduction. The post-consumption physiological effect of mango cv. "Ataulfo" pulp (MP) and peel (MC) in humans before exercise has been poorly evaluated. Objective. To evaluate the physiological response, to consumption of two mango base beverages, AM1 (200g MP/ 600mL water) and AM2 (160g MP; 40g MC / 600mL water), before and after a submaximal exercise test. Methods. The antioxidant profile and physicochemical characteristics of AM1 and AM2 were evaluated. Several cardiorespiratory, anthropometric and body composition parameters of 19 university students, prior to the consumption of AM1, AM2 and water, were evaluated in three non-consecutive sessions (self-control cases). The glycemic, lactic and antioxidant (FRAP), uric acid (AU), reduced glutathione (GSH) and lipid oxidation (TBARS) and protein carbonyls (PC) responses were evaluated in plasma before and after an incremental cycle ergometer exercise test.

The subject consumes mango pulp beverage (200 g mango pulp + 600 mL water). 2 hours later subject performs the exercise test. Washout: 1 week washout period prior to the administration of this intervention to avoid possible carryover effect.
The subject consumes mango pulp and peel beverage (160 g mango pulp + 40 g mango peel + 600 mL water). 2 hours later subject performs the exercise test. Washout: 1 week washout period prior to the administration of this intervention to avoid possible carryover effect.
The subject consumes control beverage (600 mL water). 2 hours later subject performs the exercise test. Washout: 1 week washout period prior to the administration of this intervention to avoid possible carryover effect.
Antioxidant capacity change
Assessed by FRAP change. Blood samples were drawn from the antecubital vein into EDTA test tubes at rest, before beverage intake, and immediately following the exercise test. Samples were then centrifuged at 5000 rpm for 10 min at 4°C to obtain plasma, which was withdrawn and separated into eppendorf vials, maintained at -80°C until further biochemical analysis.
Time frame: 0 min (before beverage intake), 9-15 min (immediately after exercise test)
Antioxidant capacity change
Assessed by uric acid concentration change. Blood samples were drawn from the antecubital vein into EDTA test tubes at rest, before beverage intake, and immediately following the exercise test. Samples were then centrifuged at 5000 rpm for 10 min at 4°C to obtain plasma, which was withdrawn and separated into eppendorf vials, maintained at -80°C until further biochemical analysis.
Time frame: 0 min (before beverage intake), 9-15 (immediately after exercise test)
Antioxidant capacity change
Assessed by reduced glutathione concentration change. Blood samples were drawn from the antecubital vein into EDTA test tubes at rest, before beverage intake, and immediately following the exercise test. Samples were then centrifuged at 5000 rpm for 10 min at 4°C to obtain plasma, which was withdrawn and separated into eppendorf vials, maintained at -80°C until further biochemical analysis.
Time frame: 0 min (before beverage intake), 9-15 (immediately after exercise test)
Oxidative stress change
Assessed by TBARS concentration change. Blood samples were drawn from the antecubital vein into EDTA test tubes at rest, before beverage intake, and immediately following the exercise test. Samples were then centrifuged at 5000 rpm for 10 min at 4°C to obtain plasma, which was withdrawn and separated into eppendorf vials, maintained at -80°C until further biochemical analysis.
Time frame: 0 min (before beverage intake), 9-15 (immediately after exercise test)

Lactic acid concentration change
Assessed by lactic acid concentration change. Capillary blood samples were taken from the fingertip, using a lancet and analyzed (YSI modelo 1500, Yellow Springs, USA)
Time frame: 0 min (before performing exercise test), 3 min, 6 min, 9 min, 12 min, 15 min (during exercise test)
Postprandial glycemic change
Assessed by blood glucose concentration change. Capillary blood samples were taken from the fingertip, using a lancet, and analyzed (ReliOn Confirm/micro Test Strips ARKRAY, USA)
Time frame: 0 min (before beverage intake), 30 min, 60 min, 90 min, 120 min (after beverage intake)
