Bicycling injuries can be classified into bicycle contact, traumatic, and overuse injuries. Despite the popularity of cycling, there are few scientific studies regarding injuries. Epidemiological studies are difficult to compare due to different methodologies and the diverse population of cyclists studied.

I AM obliged to Mr. Housman for pointing out a slip of expression in my review of Mr. Sharp's book. I had not confused the ratio of the I's for the ratio of the D's, but merely inadvertently used the word “stiffness” in its colloquial and more extended sense, so to include resistance to forces which would seriously bend or damage, as well as to those ...

Acta Mathematica Hungarica, 1997
The author considers a more general structure theory of simple semigroups, the basic idea being to give a construction where the term ``group'' is replaced by the term ``monoid'' [see: \textit{D. Rees}, Q. J. Math., Oxf. Ser. 19, 101-108 (1948; Zbl 0030.00802)]. The resulting construction is called a bicyclic extension.

Physical Medicine and Rehabilitation Clinics of North America, 1999
The severity of injuries secondary to bicycling range from the pain and nuisance of skin abrasions to life-threatening brain injuries. For most injuries, the key to treatment and prevention is careful assessment of bike fit and training techniques. In general, the treatment of musculoskeletal and neuropathic lesions should follow sound, physiatric ...
