The research of the influence of different intensity train on Achilles tendons′ biomechanisc characteristic and its instruction meaning to military train / 解放军医学杂志

ABSTRACT

Objective The purpose of this study was to investigate the effects of short-term and high-intensity training on the biomechanics characteristic of guinea pig's Achilles tendon, and thus to propose a new training mode for quickly enhancing the ability of withstand stress and anti-injury. Method Guinea pigs were assigned to different groups according to the training intensity they would undergo, i.e. high intensity group, medium intensity training for 8-weeks group and control group. The bilateral Achilles tendons were excised after different strength training. The variety of biomechanics characteristic of different intensity and different period were observed and compared respectively. Result Compared with the control group (8.19?0.60, 30.54?5.71), both the high intensity group (group C, 11.51?2.49,35.64?5.28, group D, 14.92?2.75, 44.29?4.09) and the medium intensity group (12.37?2.15, 36.36?4.94) show significant differences (P
