Article Synopsis
- Patients with obstructive sleep apnea (OSA) experience reduced muscle metaboreflex control of sympathetic nerve activity, but exercise training can improve this in heart failure patients.
- A study was conducted with 41 OSA patients split into trained (OSAT) and non-trained (OSANT) groups to assess the effects of exercise on muscle sympathetic nerve activity (MSNA).
- Results showed that exercise training decreased baseline MSNA and increased blood flow, significantly enhancing MSNA responses during muscle ischemia compared to the non-trained group.
Purpose: Previous studies report abnormal muscle metaboreflex control of muscle sympathetic nerve activity (MSNA) in obesity, hypertension, and heart failure. We hypothesized that obstructive sleep apnea (OSA) is associated with augmented metaboreflex control of MSNA.
Methods: Thirty-one sedentary individuals with no comorbidities (age = 52 ± 1 yr, body mass index = 28 ± 1 kg·m) without (control, n = 14) and with OSA (n = 17) defined by polysomnography, underwent echocardiography.
Study Objectives: To investigate muscle sympathetic nerve activity (MSNA) response and executive performance during mental stress in obstructive sleep apnea (OSA).
Methods: Individuals with no other comorbidities (age = 52 ± 1 y, body mass index = 29 ± 0.4, kg/m2) were divided into two groups: (1) control (n = 15) and (2) untreated OSA (n = 20) defined by polysomnography.
