Objective To explore the value of high frequency ultrasound in evaluation on the impact of recruits training on achilles tendon. Methods Totally 1773 soldiers of multiple contingents who joined the army in December 2012 were exam- ined with high frequency ultrasound before and 1 month, 3 months after recruits training. The differences of achilles tendon thickness on short axis, circumference of short axis and area of short axis in different time were compared, and abnormal results were recorded and analyzed. Results There was no significa/lt correlation between achilles tendon thickness on short axis, circumference of short axis, nor area of short axis with height, weight and body mass index （all P~0.05）. There were statistical differences in achilles tendon thickness on short axis and area of short axis （all P~0.05）, but not in achilles tendon circumference of short axis （P~0.05）. Ankle injury was observed in 13 soldiers. Pain in the achilles ten- don terminal area occurred in 12, while no special ultrasonic performance was found in 6, but soft tissue slight swelling was detected in achilles tendon terminal area in 5, and achilles tendon calcification was observed in 1 soldier. No achilles tendon rupture was found. Conclusion High-frequency ultrasound can accurately cheek achilles tendon, measure the thickness on short axis, circumferenee of short axis and area of short axis, and timely find related infantry.
