“…Additionally, recent case studies have also highlighted the capabilities of prominent vegan endurance athletes [115,116]. A case study by Wirnitzer and Kornexel (2017) reported energy intake and performance data for a female vegan cyclist competing in the 8-day Transalp Challenge 2004 (662 km, total altitude: 22,500 m).…”

Plant-Based Diets: Considerations for Environmental Impact, Protein Quality, and Exercise Performance

Plant-based diets provide well-established physical and environmental health benefits. These benefits stem in part from the degree of restriction of animal-derived foods. Historically, meat and other animal-derived proteins have been viewed as an integral component of athletes’ diets, leading some to question the adequacy of vegetarian or vegan diets for supporting athletic performance. The purpose of this review is to examine the impact of plant-based diets on human physical health, environmental sustainability, and exercise performance capacity. Based on currently available literature, it is unlikely that plant-based diets provide advantages, but do not suffer from disadvantages, compared to omnivorous diets for strength, anaerobic, or aerobic exercise performance. However, plant-based diets typically reduce the risk of developing numerous chronic diseases over the lifespan and require fewer natural resources for production compared to meat-containing diets. As such, plant-based diets appear to be viable options for adequately supporting athletic performance while concurrently contributing to overall physical and environmental health. Given the sparse literature comparing omnivore, vegetarian, and vegan athletes, particularly at the elite level, further research is warranted to ascertain differences that might appear at the highest levels of training and athletic performance.

“…To date, the impact of a plant-based diet on athletic performance is not clearly understood. Recent case reports showed that even vegan athletes can reach top athletic performances [21, 22]. Other studies dealing with a vegetarian and vegan diet related to sport are questionnaire-based and do not include nutritional or sports medical diagnostics [4, 5, 23, 24].…”

Background In search of the right nutrition for the athlete, numerous nutritional strategies and diets were discussed over time. However, the influence of plant-based diets, especially veganism, on exercise capacity has not been clarified. Methods We conducted a cross-sectional study to compare the exercise capacity of vegan (VEG, n = 24), lacto-ovo-vegetarian (LOV, n = 26) and omnivorous (OMN, n = 26) recreational runners. To determine maximal exercise capacity, participants performed an incremental exercise test on a bicycle ergometer until voluntary exhaustion. During the test capillary blood samples were taken at several time points for the measurement of arterial lactate [lac] and glucose [glc] concentrations. To determine nutrient intake, a 24 h dietary recall was conducted. Results The groups showed comparable training habits in terms of training frequency (mean 3.08 ± 0.90 time/wk., p = 0.735), time (mean 2.93 ± 1.34 h/wk., p = 0.079) and running distance (mean 29.5 ± 14.3 km/wk., p = 0.054). Moreover, similar maximum power output (P maxBW ) was observed in all three groups (OMN: 4.15 ± 0.48 W/kg, LOV: 4.20 ± 0.47 W/kg, VEG: 4.16 ± 0.55 W/kg; p = 0.917) and no differences regarding [lac] throughout the exercise test and maximum lactate could be observed between the groups (OMN: 11.3 ± 2.19 mmol/l, LOV: 11.0 ± 2.59 mmol/l, VEG: 11.9 ± 1.98 mmol/l; p = 0.648). Conclusion The data indicate that each examined diet has neither advantages nor disadvantages with regard to exercise capacity. These results suggest that a vegan diet can be a suitable alternative for ambitious recreational runners. Trial registration German Clinical Trials Register ( DRKS00012377 ).

“…Other studies have investigated plant‐based dietary patterns and endurance performance, but these have small sample sizes with cross‐sectional study designs (Hanne et al 1986; Nieman et al 1989; Nebl et al 2019) or are case studies (Leischik & Spelsberg 2014; Wirnitzer & Kornexl 2014). Deriving conclusions pertaining to the ability of a plant‐based diet to modulate endurance performance from these studies would be disingenuous as natural differences in physiology between groups could influence the results irrespective of diet.…”

Plant‐based eating patterns and endurance performance: A focus on inflammation, oxidative stress and immune responses

et al. 2020

Plant-based dietary patterns are associated with reduced risk of many chronic diseases. Athletes have increasingly been adopting plant-based diets not only for the related health benefits but for perceived improvements in endurance performance. Several theoretical mechanistic underpinnings have been described as to why a plant-based dietary pattern may improve endurance performance. This review focuses on plant-based dietary patterns and their hypothesised ability to modulate endurance performance specifically from an antioxidant, inflammatory and immunological perspective. Studies quantifying the function of plant-based dietary patterns on endurance performance are scarce; however, research exploring physiological changes in immune, oxidative and inflammatory systems with the adoption of a plant-based dietary pattern appears to be favourable. Overall, research suggests that the consumption of a plant-based diet may result in improvements in C-reactive protein, interleukin-6, fibrinogen and leukocyte concentrations, while some studies report improved lymphocyte responsiveness and improved natural killer cell functionality. These changes may be the result of an optimised intake of phytochemicals (particularly polyphenols), unrefined carbohydrates and saturated fat which could theoretically translate into small improvements to endurance performance. It is important to note that any improvement to endurance performance via these systems would likely be minor and difficult to quantify; nevertheless, the findings of the current body of evidence highlight the need for further research in this area.
