trainlow
Train-low refers to a training approach in endurance and high-performance sport where athletes perform workouts with low carbohydrate availability, typically by depleting glycogen stores or limiting carbohydrate intake around training. The goal is to elicit metabolic adaptations thought to enhance fat oxidation and mitochondrial efficiency, and to potentially improve long-term endurance capacity. In practice, train-low protocols vary and may include fasted sessions, sessions after a carbohydrate-restricted diet, or the so-called sleep-low approach in which an evening workout is followed by overnight glycogen depletion and a morning session.
Supporters argue that training with low glycogen can increase enzymes involved in fat metabolism, improve mitochondrial
Cautions: training with low carbohydrate availability can raise perceived exertion and may temporarily reduce training quality,
History: The concept emerged from research on fat oxidation and metabolic flexibility in endurance training and
