I have long wondered about the long term effects of being bent over a set of handle bars for many hours each week as per elite cyclists or triathletes, or really any person who cycles frequently. Over the last twenty odd years I have worked with many cyclists and triathletes and low back pain was not uncommon in this group and I always believed that there was a simple connection between the lumbar and thoracic posture assumed on the bike with the associated back pain or change in spinal curves. Till now I had not ever found any research based evidence to support or change my thoughts on the matter.
