Neural adaptation to physical training allows a person to better coordinate the activation of all relevant muscles producing maximum force. Nerve conduction velocity measures the speed of impulse along the motor neuron and is strongly associated with muscle contraction time. This study aimed to find out the mean motor nerve conduction velocity of the right ulnar nerve among physically trained adult males in a tertiary care centre.
This descriptive cross-sectional study was conducted in the Neurophysiology Laboratory of a tertiary care centre from 3rd November, 2019 to 2nd November, 2020. Thirty young adult males who were engaged in the physical training at a training centre for more than 3 months were studied after receiving ethical approval from the Institutional Review Committee (Reference number: 1578/019). Motor nerve conduction parameters of the right ulnar nerve were measured and data were entered in Microsoft Excel. Statistical analysis was done using the Statistical Packages for the Social Sciences version 25.0. Point estimate at 95% Confidence Interval was calculated along with frequency and percentages for binary data, and mean and standard deviation for continuous data.
Among 30 males studied, the mean motor nerve conduction velocity of the ulnar nerve was found to be 61.02±5.86 m/sec (58.92-63.11 at 95% Confidence Interval). The mean distal latency and amplitude of the muscle action potential were 2.33±0.53 ms and 8.08±1.17 mv respectively.
Our study found that the mean nerve conduction velocity of the ulnar nerve was similar when compared to studies conducted in similar settings.

神经适应身体训练使人能够更好地协调所有相关肌肉的激活,从而产生最大力量。神经传导速度测量脉冲沿运动神经元的速度,与肌肉收缩时间密切相关。本研究旨在探讨三级保健中心中经过身体训练的成年男性右侧尺神经的平均运动神经传导速度。
这是一项在三级保健中心的神经生理学实验室进行的描述性横断面研究,时间为 2019 年 11 月 3 日至 2020 年 11 月 2 日。在获得机构审查委员会的伦理批准后(参考号:1578/019),研究了 30 名在训练中心接受超过 3 个月的身体训练的年轻成年男性。测量右侧尺神经的运动神经传导参数,并将数据输入 Microsoft Excel。使用社会科学统计软件包 25.0 进行统计分析。计算了 95%置信区间的点估计值,以及二进制数据的频率和百分比,以及连续数据的均值和标准差。
在所研究的 30 名男性中,尺神经的平均运动神经传导速度为 61.02±5.86 m/sec(95%置信区间为 58.92-63.11)。肌肉动作电位的平均远端潜伏期和振幅分别为 2.33±0.53 ms 和 8.08±1.17 mV。
我们的研究发现,与在类似环境中进行的研究相比,尺神经的平均神经传导速度相似。
