Pre‐season injuries are common and may be due to a reintroduction of training loads. Tendons are sensitive to changes in load, making them vulnerable to injury in the pre‐season. This study investigated changes in A chilles tendon structure on ultrasound tissue characterization ( UTC ) over the course of a 5‐month pre‐season in elite male A ustralian football players. Eighteen elite male A ustralian football players with no history of A chilles tendinopathy and normal A chilles tendons were recruited. The left A chilles tendon was scanned with UTC to quantify the stability of the echopattern. Participants were scanned at the start and completion of a 5‐month pre‐season. Fifteen players remained asymptomatic over the course of the pre‐season. All four echo‐types were significantly different at the end of the pre‐season, with the overall echopattern suggesting an improvement in A chilles tendon structure. Three of the 18 participants developed A chilles tendon pain that coincided with a change in the UTC echopattern. This study demonstrates that the UTC echopattern of the A chilles tendon improves over a 5‐month pre‐season training period, representing increased fibrillar alignment. However, further investigation is needed to elucidate with this alteration in the UTC echopattern results in improved tendon resilience and load capacity.
