The Claim

In young men, segmental bioimpedance spectroscopy does not detect changes in leg extracellular or intracellular water following a 40 mmol/kg reduction in thigh muscle glycogen over 24 hours, suggesting that this method is insensitive to water shifts associated with glycogen depletion in this population.

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

Supports is higher

Support is ahead, but a single strong opposing study can change this.

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 young guys burn off a lot of muscle fuel (glycogen) in their legs over a day, a special body scan that measures water doesn’t pick up any change in leg water levels — meaning it might not notice the water shifts that happen when fuel stores drop.

See the scientific wording

Segmental bioimpedance spectroscopy detects no change in leg extracellular or intracellular water despite a 40 mmol/kg reduction in thigh muscle glycogen over 24 hours in young men, indicating that BIS is not sensitive to water shifts associated with glycogen depletion in this population.

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 found that even when muscle glycogen dropped a lot, the water in the legs didn’t appear to change when measured with a special device (BIS), just like the claim says.
