Acute T3 may increase MSNA and reduce conductance at fatigue without affecting oxygenation; hypothesis-generating for thyroid-exercise interactions in patients.
Does acute hyperthyroidism induced by T3 alter blood flow, muscle oxygenation, and sympathetic nerve activity during dynamic handgrip in healthy males?
Acute hyperthyroidism increases muscle sympathetic nerve activity and lowers forearm vascular conductance during fatiguing exercise without directly affecting skeletal muscle oxygenation or blood flow.
