Summary

This study aims to investigate the impact of two plant-based diets-whole food plant-based (WFPB) and plant-based meat alternatives (PBMA)-vs. an omnivorous diet (Animal) on endurance and muscular strength in recreational athletes.

Detailed description

Plant-based diets are environmentally sustainable and beneficial for cardiovascular health, but athletes are often concerned that these diets do not contain enough protein to support athletic performance. However, few randomized trials investigating the effect of plant-based vs. omnivorous diets on athletic performance have been conducted. Within this randomized crossover trial, recreational runners and resistance trainers will be assigned to three diets for four weeks each (WFPB, PBMA, and Animal). PMBA is an emerging, modern type of plant-based diet for which the impact on athletic performance has not yet been assessed. Participants will complete athletic fields at baseline and after each diet, and athletic performance on diets and study feasibility in this cohort of recreational athletes will be assessed. The study design was inspired by the original SWAP-MEAT study that investigated cardiovascular risk factors in adults consuming 8-week omnivorous and plant-based meat alternative diets (Crimarco, 2020).
