August 10, 2026 updated by: Justo Javier Pedroche Jimenez, Instituto de la Grasa

Evaluation of New Disruptive Technologies (Steam Explosion) in the Design of Tailor-made Plant Protein Hydrolysates Applied to Sport Nutrition (PROVERDE)

This randomized, placebo-controlled crossover study evaluated the safety and potential beneficial effects of a beverage containing chickpea protein hydrolysate in football players. Participants received the chickpea protein hydrolysate beverage and a matched protein-containing placebo beverage during two four-week intervention periods separated by a two-week washout period. The study assessed biochemical safety parameters, antioxidant status, inflammatory biomarkers, lipid profile, lipid peroxidation, muscle damage markers, dietary intake, and body composition.

Study Overview

Detailed Description

The study was designed as a randomized, placebo-controlled crossover nutritional intervention conducted in football players during the competitive season. Participants were randomly allocated to one of two intervention sequences, with allocation balanced according to playing position.

During the first four-week intervention period, one sequence received the experimental beverage containing chickpea protein hydrolysate, whereas the other sequence received a matched placebo beverage. This was followed by a two-week washout period. During the second four-week intervention period, the treatments were crossed over so that each participant received the alternative beverage. A further two-week washout period was included after the second intervention.

On training days, the experimental beverage was consumed 2-4 hours before training at a dose providing 0.2 g protein/kg body weight and approximately 30 minutes after training at a dose providing 0.3 g protein/kg body weight. The placebo beverage followed the same administration schedule and was designed to have a similar appearance and taste and the same protein content, but from a different protein source.

Blood sampling, dietary assessment, and anthropometric measurements were scheduled at baseline and during the intervention and washout periods. The study evaluated biochemical markers related to protein and hepatic metabolism, hematological parameters, glucose and insulin, antioxidant status, inflammatory biomarkers, lipid profile, lipid peroxidation, muscle damage markers, adverse events, dietary intake, and body composition.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Chickpea Protein Hydrolysate Followed by Maltodextrin Placebo
Participants received the chickpea protein hydrolysate beverage for four weeks, followed by a two-week washout period. They subsequently received the maltodextrin placebo beverage for four weeks, followed by a final two-week washout period.
A powdered beverage containing chickpea protein hydrolysate was reconstituted in water before consumption. On training days, participants consumed a dose providing 0.2 g protein/kg body weight 2-4 hours before training and 0.3 g protein/kg body weight approximately 30 minutes after training. The intervention was administered for four weeks during the corresponding study period.
Experimental: Maltodextrin Placebo Followed by Chickpea Protein Hydrolysate
Participants received the maltodextrin placebo beverage for four weeks, followed by a two-week washout period. They subsequently received the chickpea protein hydrolysate beverage for four weeks, followed by a final two-week washout period.
A maltodextrin-containing placebo beverage designed to resemble the chickpea protein hydrolysate beverage in appearance and taste. The placebo was administered according to the same timing schedule as the experimental beverage for four weeks during the corresponding study period.
