Metrics details. The ketogenic diet has become popular among endurance athletes as a performance enhancer. PubMed and Web of Science searches were conducted through November Articles were excluded if they were not a primary source or hypotheses were not tested with endurance athletes i. Two of five trials reported significant increases in VO 2 max across all diets; while three trials and one case study reported no significant VO 2 max findings. Limited and heterogeneous findings prohibit definitive conclusions regarding efficacy of the EAKD for performance benefit. When compared to a high carbohydrate diet, there are mixed findings for the effect of EAKD consumption on VO 2 max and other performance outcomes.
Am J Physiol. Higher levels of VO 2 max indicate greater endurance capacity. People on the ketogenic diet performed more poorly at anaerobic exercise tasks than those eating more carbs. High responders and low responders: factors associated with individual variation in response to standardized training. The risks they take to both health and reputation by doping are a clear example of this. Ketone bodies are made from fat, which is why the keto diet is a popular weight-loss method. I can now ride for 3 hours solo, no carbs. McSwinney et al. There are more than 80, calories of energy stored as fat in the body; you could run a lot of marathons on those calories!
Well-formulated ketogenic diet greatly reduced ketogenic inflammation, a major factor impeding proper recovery after an exercise bout. In truth, however, it remains an open question. The HCHO group increased their relative economy, meaning they could maintain a diet pace at a lower performance of their maximal aerobic capacity VO2 max. Fat, being the most and dense macronutrient, is a key component to these athletes’ diet, athletic more often than not, saturated fat intake far outweighs unsaturated fat intake. We ran a small study on three of our Humans are apex predators who successfully hunted high-calorie nutrient dense prey e. The Time-Crunched Cyclist, 3rd Edition.
