Purpose: This study was designed to investigate the effects of playing badminton on calcaneal bone properties. Methods: Eleven sedentary collegiate women were recruited. They played badminton for 75 min, 2 days per week, for 10 weeks. The right calcaneus was assessed to measure speed of sound and broadband ultrasound attenuation using a quantitative ultrasound device. A stiffness index was derived from both the speed of sound and broadband ultrasound attenuation. Results: After the training period, broadband ultrasound attenuation and stiffness index did not change significantly, whereas speed of sound significantly increased, Conclusion: The results indicate that playing badminton influences calcaneal bone properties in a positive manner.
