Abstract

Objective: Assess the association between leisure inline skating practice and knee joint functionality in adults in Lima, Peru. Methods: This analytical cross-sectional study took place in Lima, Peru. The population involved 120 adults of both sexes who practiced leisure activities such as running, roller skating and cycling. The knee functionality has been evaluated by IKDC (International Knee Documentation Committee). In addition, the lower limb alignment was analyzed with PAS program (Postural Assessment software). Information like age, sex and activities features were analyze through surveys. For the analysis, it was used the T Test of Student for a mean difference and a Multiple Linear Regression Analysis for the confusing variable control. Results: There were 120 survey respondents between 36,1 years old. The 40,3% of the population did skating and the rest of population did other activities (running or cycling). After comparing the knee alignment level, the roller skaters had an average of 4,75 points less than the non-roller skaters (IC95%: -9,12 a -0,39). This difference was significant even after adapt the effects of age, sexes, lateral dominance and knee alignment. Conclusion: The roller skaters present a less knee functionality than the non-roller skaters. This could show some movements or posture adopted by roller skaters a damage for their knees.
