The Claim
In overweight dysglycemic and normal weight normoglycemic men, a 12-week combined endurance and strength exercise program is associated with improved insulin sensitivity (measured by glucose infusion rate during hyperinsulinemic euglycemic clamp), decreased plasma concentrations of cysteine and glutathione, and increased plasma glutamine.
What the research says
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.
In men with overweight and impaired glucose metabolism or normal weight and normal glucose metabolism, a 12-week program of combined endurance and strength exercise is associated with higher insulin sensitivity, lower levels of cysteine and glutathione in the blood, and higher levels of glutamine in the blood.
See the scientific wording
In overweight dysglycemic and normal weight normoglycemic men, a 12-week combined endurance and strength exercise program is associated with improved insulin sensitivity, as measured by glucose infusion rate during hyperinsulinemic euglycemic clamp, alongside decreased plasma concentrations of cysteine and glutathione and increased plasma glutamine, suggesting a link between sulfur-containing amino acid metabolism and metabolic health.
When a person exercises, their muscles and fat tissue produce more reactive molecules that cause stress. The body responds by using a specific pathway to convert one amino acid into another, which builds a molecule that handles this stress. After regular exercise, the body no longer needs to make as much of this stress-handling molecule because its energy factories inside cells become more efficient. This lets the cells take up sugar from the blood more effectively, improving how the body responds to insulin.
What the research says
1 studyAfter 12 weeks of cycling and strength training, men with prediabetes or normal blood sugar became better at using insulin, and their blood showed lower levels of two stress-related molecules (cysteine and glutathione) and higher levels of glutamine—suggesting exercise helps the body manage energy and stress better.
