The Claim

In adults with obesity, both high-intensity interval training and moderate-intensity continuous training increase skeletal muscle hexokinase II protein abundance by approximately 70% after 12 weeks, indicating an enhanced capacity for glucose uptake and phosphorylation independent of insulin signaling.

Source: Moderate-intensity exercise and high-intensity interval training affect insulin sensitivity similarly in obese adults.

How it works
1 study reviewed
In plain English

In adults with obesity, 12 weeks of either high-intensity interval training or moderate-intensity continuous training increases the amount of hexokinase II protein in skeletal muscle by about 70%, which enhances the muscle's ability to take up and process glucose without relying on insulin.

See the scientific wording

In adults with obesity, both high-intensity interval training and moderate-intensity continuous training increase skeletal muscle hexokinase II protein abundance by approximately 70% after 12 weeks, suggesting enhanced capacity for glucose uptake and phosphorylation independent of insulin signaling.

Why this might work

When muscles use up their stored sugar during exercise, a cellular energy sensor turns on and triggers more glucose transporters to move to the muscle surface and more enzymes to trap glucose inside the cell, allowing more sugar to enter and be used for energy without needing insulin.

1 study
  1. Study: Moderate-intensity exercise and high-intensity interval training affect insulin sensitivity similarly in obese adults.

    The study found that in people with obesity, doing either short, intense workouts or longer, moderate workouts for 12 weeks increased a key muscle protein (hexokinase II) by about 70%, which helps muscles take in sugar — exactly what the claim says.
