Prevalence of musculoskeletal pain and its relationship with Body mass index ( BMI ) in master swimmers

The aim of this study was to investigate the prevalence of musculoskeletal pain and its relationship with body mass index in veteran swimmers. The method of the present study is a cross-sectional study in terms of time section, the data of which are collected in the field and in terms of examining and analyzing the relationships between the variables measured are correlational research. In this study, the researcher measured the prevalence of musculoskeletal pain using the Nordic ۱۹۸۷ questionnaire, body mass index (BMI) and pain measurement scale (VAS), swimming history and weekly exercise rate and studied the relationship between these variables. . The statistical population of the study consists of all veteran swimmers in the country. The sampling method is random. And ۱۱۶ veteran swimmers were selected. The questionnaires were obtained through a statistical sample through the Veterans Committee and as a link on WhatsApp and were distributed among all swimmers. Descriptive statistics including calculation of central tendency and scatter indices (mean, standard deviation, variance and amplitude) and correlation test were used to examine the relationship between the prevalence of musculoskeletal pain and body mass index in veteran swimmers. For all analyzes, the significance level of ۰.۰۵ was considered statistically significant and the analyzes were performed using SPSS ۲۲ software. The results showed that most of the musculoskeletal pain of the participants were related in the first rank (shoulder) and in the second and third rank, respectively (back and knees). The results also indicate that there is a significant relationship between body mass index and the prevalence of musculoskeletal pain in veteran swimmers (p = ۰.۰۰۰۱). There was no significant relationship between swimming history and prevalence of musculoskeletal pain in veteran rats (p = ۰.۰۸۴). There is a significant relationship between the amount of exercise per week and the prevalence of musculoskeletal pain in veteran carpenters (p = ۰.۰۰۰۱). According to the findings of this study, the prevalence of musculoskeletal disorders in veteran rats, especially in the shoulder, waist and knee areas, can not only reduce swimming performance, but can also affect their normal life.
