Abstract

Recently we reported similar performances in both progressive tests to exhaustion (VO 2 max) and 5km running time trials (5KTT) after consuming low-carbohydrate, high-fat (LCHF) or high-carbohydrate, low-fat (HCLF) diets. Accordingly, we tested the null hypothesis that the metabolic responses...

Description

The study examines the effects of high fat and low carbohydrate diets on exercise performance.
