This study represented a unique opportunity to understand changes in the human motion biomechanics during basic locomotion within a time interval of 4 years, when the monitored individual regained his original aerobic fitness, running performance and body mass index as prior to the injury. The participant visited the laboratory a month prior to the injury and during 4 years after the surgery. The surgery, subsequent rehabilitation and a 4-year running training programme in the studied recreational athlete did not completely eliminate the consequences of the Achilles tendon rupture. The function muscle deficit is namely manifested by a lower net plantar flexion moment and a lower net-generated ankle joint power during the take-off in the stance phase. The greater dorsal flexion in the affected ankle joint at the first contact with the ground and consequently higher peaks of ground reaction forces during running are consequences of the longer Achilles tendon in the affected lower extremity and weakened calf muscles.
本研究提供了一个独特的机会，以了解在4年的时间间隔内，当被监测个体恢复到受伤前的有氧适能、跑步表现和体重指数时，其在基本运动过程中人体运动生物力学的变化。参与者在受伤前一个月以及手术后的4年里前往实验室。在所研究的业余运动员中，手术、随后的康复治疗以及4年的跑步训练计划并未完全消除跟腱断裂的后果。功能肌肉缺陷具体表现为在站立期起跳时足底屈力矩较低以及踝关节产生的净功率较低。患侧踝关节在首次接触地面时背屈更大，因此在跑步过程中地面反作用力峰值更高，这是患侧下肢跟腱更长以及小腿肌肉无力的结果。
