To assess the frequency and duration of symptoms suggesting peripheral nerve compression after long distance cycling.
A questionnaire based cross sectional study among 260 participants in a Norwegian annual bicycle touring race of 540 km.
Thirty-five of 160 responding males (22%) reported symptoms from the innervation area of the pudendal or cavernous nerves. Thirty-three had penile numbness or hypaesthesia after the tour. In 10, the numbness lasted for more than one week. Impotence was reported by 21 (13%) of the males. It lasted for more than one week in 11, and for more than one month in three. Both genital numbness and impotence were correlated with weakness in the hands after the ride, a complaint reported by 32 (19%) of all 169 respondents. Forty-six cyclists (30%) indicated paraesthesia or numbness in the fingers, half of them from the ulnar nerve area only.
The frequency of impotence, numbness of the penis, hand weakness and sensory symptoms from the fingers in bicycle sport may be higher than hitherto recognized. It afflicts both experienced cyclists and novices. In some, the complaints may last up to eight months. Besides changing the hand and body position on the bike, restricting the training intensity, and taking ample pauses may also be necessary in prolonged and vigorous bicycle riding to prevent damage to peripheral nerves.
评估长距离骑行后提示周围神经受压症状的发生频率和持续时间。
对挪威一场540公里年度自行车巡回赛的260名参与者进行了一项基于问卷的横断面研究。
160名有回应的男性中，35人（22%）报告有来自阴部神经或海绵体神经支配区域的症状。33人在骑行后出现阴茎麻木或感觉减退。其中10人麻木持续超过一周。21名（13%）男性报告有勃起功能障碍。11人持续超过一周，3人持续超过一个月。在所有169名有回应的参与者中，32人（19%）报告有手部无力，生殖器麻木和勃起功能障碍均与骑行后手部无力有关。46名骑行者（30%）表示手指有感觉异常或麻木，其中一半仅来自尺神经区域。
自行车运动中勃起功能障碍、阴茎麻木、手部无力和手指感觉症状的发生频率可能高于迄今所认识到的。无论是有经验的骑行者还是新手都会受到影响。在一些人中，这些症状可能持续长达八个月。除了改变自行车上的手部和身体姿势外，在长时间剧烈骑行中，限制训练强度并充分休息对于预防周围神经损伤可能也是必要的。
