Prevalence of Chronic Muscular Skeletal Pain and Associated Factors of Adult and Adolescent Weight Lifters. Descriptive Cross Sectional Study

Karunanayake AL*

Introduction: Weight lifting is a popular sport in Sri Lanka. This descriptive cross sectional study was done among adult and adolescent weight lifters in the Western and North eastern provinces of Sri Lanka. Objectives: To determine the prevalence of chronic pain affecting the muscular skeletal system, whether their training habits differ from the guidelines recommended by the International Federation of Sports Medicine (IFSM) and the association between the training habits and the number of regions affected with chronic muscular skeletal pain.

Methodology: A structured interviewer administered questionnaire was used to collect data with regard to their demographic data, symptoms related to musculoskeletal system and training habits. Bivariant and multivariate analysis were done to determine the associations.

Results: Total sample: 50, Age range: 13-29yrs, Mean age (SD): 22.6 (4.1). Males accounted for 88%. Symptoms were present in 84% of subjects. The prevalence of pain in the lower back (22%), wrist (22%), knee (24%) and shoulder (20%) was high in our study. The mean frequency/week (5 days/week) and the mean duration/day (120 minutes/day) of training in our study was more than the recommended guidelines of 3 days/week and 60-90minutes/ day of IFSM. Only the training frequency/week had a significant positive association (P=0.03, Exp B=1.845) with the number of regions in the muscular skeletal system affected by chronic pain.

Conclusions: The most common regions affected with pain were lower back, knee and wrist. The frequency and duration of training sessions were higher in our study compared to the recommended levels of strength training. Only the training frequency/week had a significant positive association with the number of regions affected with chronic muscular skeletal pain. These study findings will be useful to trainers in preventing muscular skeletal injuries of weight lifters during training.
