Riding a mountain bike for a long time on the cervical spine has no obvious benefits, and may lead to cervical spine-related pain, activity unfavorable symptoms aggravated. The reasons are mainly the following two aspects: First, when riding a mountain bike, the body presents a forward leaning state, the head is slightly tilted back, this state will lead to the cervical spine part of the muscles, ligaments and other soft tissues continue to tense, fatigue, and by the tension, there will be excessive fatigue to form a strain, leading to more inflammation in the local area as well as lactic acid metabolite accumulation increases, muscle elasticity, toughness will be reduced, and lead to localized More fiber hyperplasia, over time there will also be local calcium salt deposition to form calcified hyperplasia. Second, riding mountain bike process wind is relatively large will lead to cervical spine parts of the cold, once the cold will lead to cervical blood circulation further down, the muscles will become more tense, so it will aggravate the symptoms of cervical spondylosis.
