The Claim
In newly diagnosed female Graves' hyperthyroidism patients with reduced skeletal muscle index, sustained high-intensity intermittent exercise results in a greater decline in mean power output compared to healthy controls, indicating impaired endurance capacity despite preserved peak explosive power, which is associated with altered cardiopulmonary efficiency and metabolic fatigue accumulation.
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.
Women newly diagnosed with Graves' disease and low muscle mass experience a larger drop in sustained power output during high-intensity intermittent exercise than healthy women, even though their maximum explosive strength remains unchanged; this is linked to reduced efficiency in heart and lung function and faster buildup of metabolic fatigue.
See the scientific wording
In newly diagnosed female Graves' hyperthyroidism patients with reduced skeletal muscle index, sustained high-intensity intermittent exercise leads to a greater decline in mean power output compared to healthy controls, suggesting impaired endurance capacity despite preserved peak explosive power, likely due to altered cardiopulmonary efficiency and metabolic fatigue accumulation.
High levels of thyroid hormones cause the body to burn energy too quickly and trigger excessive inflammation during intense exercise. This overwhelms the muscles' ability to manage energy and clear waste, causing fatigue to set in faster during repeated bursts of effort. Even though the muscles can still produce a strong initial burst, they cannot keep up over time because the body's energy system becomes inefficient and overloaded.
What the research says
1 studyWomen newly diagnosed with Graves' disease have less muscle and get tired faster during repeated intense exercise bursts, even though they can still burst out power just like healthy women. Their bodies just can't keep up over time because their metabolism and inflammation respond differently.
