Outcome Measures

Primary Outcomes (2)

  • Microneurography

    Muscle sympathetic nerve activity (MSNA) is recorded directly from the peroneal nerve using the microneurography technique. Multiunit postganglionic muscle sympathetic nerve recordings is made using a tungsten microelectrode. All of the recordings of MSNA met previously established and described criteria. MSNA is quantified as burst frequency (bursts per minute).

    4 months of exercise training/testosterone replacement

  • Forearm blood flow

    Forearm blood flow is measured by venous occlusion plethysmography. The nondominant arm is elevated above heart level to ensure adequate venous drainage. A mercury-filled silastic tube attached to a low-pressure transducer is placed around the forearm and connected to a plethysmography. Forearm blood flow is determined on the basis of a minimum off four separate readings. Forearm vascular conductance is calculated by dividing forearm blood flow by mean arterial pressure times 100 and expressed in arbitrary units.
