Sponsor's own description

Post-exercise nutrition is an important factor in a nutrition plan for physically active subjects. Focusing on that, the Serbian group is developing protein bars enriched with sports supplements. Slovenian partner group will investigate the effect of new protein bar consumption on body composition, biochemical parameters, and muscle regeneration after training. The new bar will be compared with a commercially available bar.
