The Claim

Segmental bioimpedance spectroscopy shows no significant changes in leg intracellular or extracellular water following muscle glycogen depletion, even when glycogen levels decrease by more than 50%, indicating that bioimpedance spectroscopy is not affected by glycogen-related mass fluctuations in the context of athletic body composition monitoring.

Source: Muscle glycogen depletion does not alter segmental extracellular and intracellular water distribution measured using bioimpedance spectroscopy.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Description
1 study reviewed
In plain English

Even when athletes burn off more than half their muscle sugar, a body scan tool called BIS doesn’t see fake changes in muscle water — so it’s a reliable way to track body changes during training.

See the scientific wording

Segmental bioimpedance spectroscopy detects no significant changes in leg intracellular or extracellular water following muscle glycogen depletion, even when glycogen levels drop by over 50%, suggesting BIS is robust to glycogen-related mass fluctuations in athletic body composition monitoring.

What the research says

1 study
  1. Study: Muscle glycogen depletion does not alter segmental extracellular and intracellular water distribution measured using bioimpedance spectroscopy.

    The study shows that even when muscles lose a lot of glycogen (which holds water), the water levels in the legs don’t appear to change according to BIS measurements, meaning the tool works well even when glycogen changes.
