RESUMO
OBJECTIVE: We aimed to verify the reliability of muscle thickness and luminance evaluation of the deep leg muscles using an ultrasound device. DESIGN: Cohort study. SETTING: Track and field, Participants: high school track and field long distance athletes (N = 10, female: 50.0%, age = 16.0 ± 2.8 years, BMI = 18.2 ± 2.3 kg/m2) PARTICIPANTS: This study included Japanese high school track and long-distance field athletes. MAIN OUTCOME MEASURES: The thickness and echo intensity of tibialis posterior, flexor digitorum longus, and soleus muscles in the posterior medial tibia were clarified. RESULTS: The echo intensity evaluation of the tibialis posterior muscle showed an additive error. CONCLUSION: The study suggested that the results could be clinically applied clinically, except for the evaluation of echo intensity of the posterior tibialis muscle.
