A small device that zaps a major nerve connecting the heart and brain could one day help improve fitness for coach potatoes and people with heart failure, an early trial suggests.
Wearing the stimulator for just 30 minutes a day increased oxygen intake during exercise by four per cent, according to researchers - who hope it could eventually be used to help more inactive people.
The device, clipped to the outer ear, sends gentle electrical pulses to increase the activity of the vagus nerve, which plays a key role in regulating heart function.
Led by researchers at University College London and Queen Mary University of London, the study involved 28 healthy volunteers.
一半被给予神经刺激器每天佩戴30分钟,而另一半则获得了一个虚拟设备。
两周休息后,组交换设备。戴上刺激器。
”该试验发表在《欧洲心脏》杂志上,发现迷走神经的'功能障碍'与运动耐受性受损密切相关。

在欧洲心脏期刊上发表的试验,发现神经刺激器更加强烈地锻炼那些人,而不是穿着duumm sclass < /p par,就可以更加强烈地锻炼身体,从而发现那些穿着这些刺激性的人比摩尔< /p < /p plosgar,能够在欧洲心脏期刊上发表的试验更强烈地锻炼。佩戴神经刺激器的锻炼比佩戴虚拟设备时更加强烈。
一周后,刺激器在运动过程中增加了4%的氧气摄入量。
它也使最大呼吸速率平均每分钟增加了四个呼吸,并且在运动过程中平均每分钟每分钟每分钟,

Professor Bryan Williams, chief scientific and medical officer at the British Heart Foundation, which funded the study, said: 'This early study suggests that a simple technology, which harnesses the connection between the heart and the brain, can lead to improvements in fitness and exercise tolerance.
''虽然需要更多的研究涉及心血管疾病的人,但有一天可以用作改善心力衰竭患者的福祉和生活质量的工具。'
