The Claim
In older adults without diabetes, higher insulin resistance, as measured by HOMA-IR, is associated with slower phosphocreatine recovery after exercise, indicating reduced skeletal muscle mitochondrial oxidative capacity, independent of age, sex, body composition, and physical activity levels.
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 older adults without diabetes, higher insulin resistance is linked to a slower recovery of phosphocreatine after exercise, which reflects lower mitochondrial energy production in skeletal muscle, even when accounting for age, sex, body composition, and physical activity.
See the scientific wording
In older adults without diabetes, higher insulin resistance, as measured by HOMA-IR, is associated with slower phosphocreatine recovery after exercise, indicating reduced skeletal muscle mitochondrial oxidative capacity, independent of age, sex, body composition, and physical activity levels.
When muscle cells become resistant to insulin, their mitochondria struggle to produce energy efficiently. This causes electrons to leak during energy production, generating harmful molecules that damage the mitochondria. As a result, the muscle cannot restore its energy stores quickly after exercise, leading to slower recovery.
What the research says
1 studyIn older adults without diabetes, higher insulin resistance is linked to slower muscle energy recovery after exercise, meaning their muscle cells’ power plants (mitochondria) aren’t working as well—even when you account for age, weight, and how active they are.
