  1. The bold values indicate statistical significance at the p = 0.05 level. Initial Ankle Angle was taken from left ankle at instant of initial contact during shod running. ATRS means Achilles tendon total rupture score [13]. Silfverskiöld test indicate increased passive affected ankle dorsiflexion of the AT group [17]. Plantarflexion strength indicate maximal isometric plantarflexion strength on affected side of the AT group and matched ankle of the CTRL group [23]. AT length difference means absolute value of length difference between left and right AT. Physical activity evaluated according to 6-graded scale classification system of physical activity [18]
