Changes in knee extensor strength 8 and 24 hours after 2 types of endurance exercise [Annual conference of the british association of sport and exercise sciences]

A decreased kinematic variability was found in runners with patellofemoral pain compared with uninjured runners (Hamill et al., 1999: Clinical Biomechanics, 14, 297 – 308). Therefore, the aim of this study was to investigate the kinematic, kinetic, and EMG activity variability in runners with Achilles tendinopathy. Thirty-four uninjured runners (body mass 67.8±10.5 kg; height 1.71±0.09 m; age 37.0±9.2 years) and 25 runners diagnosed with Achilles tendinopathy (body mass 77.6±12.6 kg; height 1.78±0.07 m; age 41.8±9.7 years) were recruited. After receiving institutional ethics approval, the participants performed 10 trials at a self-selected running ...
