We suggest conducting further prospective studies with longer follow-up periods and with more accurate diagnosis. In conclusion, this prospective cohort study demonstrated that the incidence of RRI in recreational runners was 31% or 10 RRIs per 1000 hours of running exposure. The most

frequent check details type of injury was muscle injury and the most affected anatomical region was the knee. The relevant risk factors for RRI in recreational runners were identified in this study as previous RRI and speed training, while the protective factor identified was interval training. eAddenda: Appendix 1 and 2 available at jop.physiotherapy.asn.au Ethics: The Ethics Committee of the Universidade Cidade de São Paulo approved this study (number 13506607).

“Clinical trial registration involves placing the protocol for a clinical trial on a free, publicly available and electronically searchable register. Registration is considered to be prospective if the protocol is registered before the trial commences (ie, before the first participant is enrolled). Prospective registration has several potential advantages. It could help avoid trials being duplicated unnecessarily and it could allow people with health problems to identify trials in which they might participate.
