Interventions

This is a single-blind placebo-controlled parallel study. The participants were randomly allocated to the ascorbic acid (AA) microencapsulated with pea protein isolate (PPI) (PPI-AA) group (n = 5), fr
however, no foods containing vitamin C were included. Two hours after the breakfast, athletes performed an exercise protocol that simulates the physical effort of a soccer game. Immediately after the
each participant ingested either 25 mL bottle containing free AA (free-AA), AA microcapsules (PPI-AA), or no added substance (P). The amount of AA in the PPI-AA and free-AA beverages was 1 g each. Bl

Design outcomes

Primary

MeasureTime frame
Expected outcome 1: It is expected that microencapsulation of AA with PEA can decrease the absorption rate and prolong the antioxidant capacity against oxidative stress in football players.;Outcome found 1: PPI-AA microcapsules facilitated sustained release of AA and the intake of these microcapsules may mitigate OS and cell damage after a simulated soccer game, and thereby reducing the recovery period for athletes.

Secondary

MeasureTime frame
No secondary outcomes are expected
