Abstract text The ageing process causes significant reductions in functionality, especially the muscular system which in turn also affects the tendons, increasing the chances of injuries. One way to reduce this process is through exercise training. Thus, the aim of this study was to determine the effect of resistance training (RT) in tendons of aged rats. The animals were divided into four groups: young sedentary (YS, n = 5), young trained (YT, n = 5), old sedentary (OS, n = 5) and old trained (OT, n = 5). Trained rats were submitted to the climb protocol with progressive load for 12 weeks. After the training period, the calcaneal tendon (CT); superficial flexor tendon (SFT) and deep flexor tendon (DFT) were removed for biomechanical analyses. The results demonstrated that RT may be able to prevent progressive decrease in tendon function during ageing. Although RT has prompted significant biomechanical changes in trained aged rats, there was no increase in cross-sectional area, either a reduction in tendon stiffness. Therefore, the tendons are adapted according to the stimulus, in this case the OT showed better biomechanical responses when compared with OS. Thus, the RT may be an excellent strategy to maintain the tendon properties during ageing.
