Prevalence of generalised joint hypermobility in relation to selected medical and training indicators in swimmers: Randomised control study

Abstract

Generalised joint hypermobility (GJH) is characterised by the range of motion that exceeds normal limits in multiple joints. GJH is relatively common. When it is accompanied with other manifestations, it is defined as a health-related disorder, like Joint Hypermobility Syndrome (JHS) or the Ehlers–Danlos Syndrome - Hypermobile Type (hEDS). The prevalence of GJH is higher in sporting than in the general population. The aim of the study was to investigate the prevalence of GJH in competitive swimmers and its relation to the number and type of injuries, pain and selected anthropological and training indicators. The research group consisted of 97 competitive Polish swimmers (50 males; 47 females) aged 15-24 years. Body stature and body mass was measured. Participants completed a questionnaire to collect demographic data and information on previous injuries. Concerning joint hypermobility, participants were examined with the Beighton Scale. Spearman’s rank correlation test was applied for analysis. GJH is an often-occurring symptom among the researched group. There was no correlation between selected acute injuries nor chronic pain and GJH in the study group. Several other correlations were noted.
