SWAP-MEAT With Athletes for MC-URC: Three Diets on Athletic Performance

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.

The SWAP-MEAT study compared the impact of consuming diets containing animal meat (primarily beef and pork) vs. plant-based alternative meats (Beyond Meat products) on health risk factors, cardiometabolic risk factors, and the gut microbiome in generally healthy adults. The SWAP-MEAT Athlete pilot study explored the impact of these diets on athletic performance instead of health biomarkers and cardiovascular disease.

The purpose of this study is to replicate the pilot study with the exception of using undergraduate students who have access to Stanford dining halls, rather than graduate students who have to buy and prepare their own food. It will be a 2x4-6 week randomized crossover trial that contains two arms: animal meat and plant-based alternative meat. Generally healthy recreational athletes will be recruited and complete athletic performance field tests at the end of each diet in order to assess athletic performance outcomes. From the SWAP-MEAT: Athlete pilot study, the investigators can attest to the feasibility of the trial and have justification for conducting this larger study.

This study will aim to focus on BIPOC (Black, Indigenous, People of Color) undergraduate students. By doing so, the investigators can gain a better understanding of the potential barriers and challenges to their adoption in diverse populations, for example, understanding of how cultural differences influence dietary choices and preconceptions about plant-based diets and animal protein alternatives. This study aims to address these limitations and provide valuable insights into the effectiveness of plant-based diets for recreational athletes, as well as potential barriers and challenges to their adoption in diverse populations.
