The categorization of amateur cyclists as research participants: findings from an observational study.
2018
Sampling bias is an issue for research involving cyclists. The heterogeneity of cyclist populations, on the basis of skill level and riding purpose, can generate incorrect inferences about one specific segment of the population of interest. In addition, a more accurate categorization would be helpful when physiological parameters are not available. This study proposes using self-reported data to categorize amateur cyclist types by varying skill levels and riding purposes, therefore improving sample selection in experimental studies. A total of 986 cyclists completed an online questionnaire between February and October 2016. Two-step cluster analyses were performed to generate distinct group…
The association of bike fitting with injury, comfort, and pain during cycling: An international retrospective survey
2018
Although bike fitting is recommended to help reduce injury risk, little empirical evidence exists to indicate an association between bike fitting and injury incidence. The aim of the study was to determine the effect of bike fitting on self-reported injury, comfort, and pain while cycling from a worldwide survey of cyclists. A total of 849 cyclists completed an online questionnaire between February and October 2016. Questionnaire collected data on respondent demographics, cycling profile, bike fitting, comfort and pain while cycling, and injury history. The main predictor variable was bike fitting (yes, by the respondent, i.e. user bike fitting; yes, by a professional service; or no). Covar…
Examination of the risk factors associated with injured recreational padel players in Spain.
2017
BACKGROUND: Padel (called paddle in North America) is a relatively new racquet sport, with steady participation increases over the past 50 years. However, there is a need for data examining injury and associated risk factors. The study examined how intrinsic (e.g. age and sex) and extrinsic factors (e.g. padel participation and equipment) were associated with injury in recreational padel players. METHODS: A self-administered questionnaire completed by 80 recreational padel players between September 2014 and March 2015 acquired data on: respondent demographics and padel-related activities; the number of injuries within the past year; characteristics of the last injury sustained; and extrinsi…
A retrospective international study on factors associated with injury, discomfort and pain perception among cyclists
2019
International audience; Although cycling has been associated with overuse/fatigue and acute injuries, there is lack of information regarding associated risk factors and prevention factors. The objective of the study was to determine the factors associated with injury, and perceptions of discomfort and pain in cyclists. A total of 739 cyclists completed an online questionnaire between February and October 2016. The questionnaire acquired information on participant demographics, characteristics related to cycling profile and fitness training, bike components and cycling posture, self-reported perceptions of comfort and pain, and injuries sustained in the last 12 months. Logistic regression mo…
