Marathon Handbook reports on a study about kale sprouts and lactate levels. Healthy adults drank a kale sprout beverage before cycling. Lactate levels dropped slightly, but no performance changes noted. Researchers caution against performance assumptions.

The study involved 15 participants, cycling at submaximal rates. They consumed a beverage with red kale sprouts, broccoli sprouts, or a placebo. Results showed a small lactate reduction but no performance boost. Marathon Handbook advises against altering routines based on these findings. Read more culture coverage.

Marathon Handbook emphasizes that while kale sprouts may lower lactate, it does not guarantee better performance. Runners should maintain their current lactate-threshold targets and supplement routines. Kale remains a healthy dietary option. Related: Edmonton Marathon Course Measurement Error Explained.
