The Claim

In older adults without diabetes, longer duration and greater severity of hyperglycemia exposure, as estimated by cumulative OGTT 2-hour glucose levels over prior visits, are independently associated with reduced skeletal muscle mitochondrial oxidative capacity.

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 plain English

In older adults without diabetes, higher and longer-lasting blood glucose levels measured over time are linked to lower ability of skeletal muscle mitochondria to produce energy through oxidative processes.

See the scientific wording

In older adults without diabetes, longer duration and greater severity of hyperglycemia exposure, as estimated by cumulative OGTT 2-hour glucose levels over prior visits, are independently associated with reduced skeletal muscle mitochondrial oxidative capacity.

Why this might work

Over time, high blood sugar levels cause mitochondria in muscle cells to work less efficiently, leading to more harmful molecules being produced. These molecules damage the mitochondria's internal components, making them even worse at producing energy. This damage accumulates and reduces the muscle's ability to recover energy after use.

  1. Study: Insulin Resistance Is Associated With Reduced Mitochondrial Oxidative Capacity Measured by 31P-Magnetic Resonance Spectroscopy in Participants Without Diabetes From the Baltimore Longitudinal Study of Aging

    In older people without diabetes, having higher blood sugar levels over many years is linked to muscles being less able to recover energy after exercise, even if they’re not insulin resistant right now.
