Normalidades del rango de movimiento y fuerza muscular en cadera de bailarines de folclor

Abstract

Introduction: Folk dance requires high levels of hip flexibility and strength due to its physical and biomechanical demands. However, the relationship between range of motion (ROM) and muscle strength in these dancers has been little studied compared to other disciplines such as ballet or contemporary dance. This study seeks to establish reference values in folk dancers, contributing to injury prevention and performance improvement.

Objective: To determine normal values for range of motion and muscle strength in the hip of folk dancers, establishing biomechanical patterns specific to this discipline.

Materials and methods: An observational, prospective, cross-sectional study was conducted in 100 folk dancers (50 men and 50 women). ROM was measured with a digital goniometer and muscle strength with a portable dynamometer. Statistical tests were applied to evaluate differences between limbs and gender.

Results: ROM values similar to those of other dance disciplines were found, but with less hip extension. Extension strength was the highest, while abduction showed the lowest values. No direct correlation was found between ROM and muscle strength. Discussion: Significant differences were observed between men and women, with men showing greater strength and women greater ROM.

Conclusions: The results indicate that folkloric dancers present specific biomechanical patterns, with asymmetries in ROM and variations in muscle strength. Low abduction strength could represent a risk factor for injury. These findings highlight the importance of training strategies focused on improving stability and preventing injuries in folkloric dance.
