The interaction between fascicle and tendinous tissues (TT) in short contact drop jumps (DJ) with three different drop heights (LOW, OP and HIGH) was examined with eleven subjects. The ground reaction force, ankle and knee joint angles were measured together with real-time ultrasonography (fascicle length) and electromyographic activities of the medial gastrocnemius (MG) and vastus lateralis (VL) muscles during the movement. With increasing the drop heights, the braking force and flight time increased from LOW to OP (P<0.05). In HIGH, the braking force increased but the flight time decreased as compared to OP (P<0.05). During contact of LOW and OP conditions, the length of muscle-tendon unit (MTU) and TT underwent lengthening before shortening in both MG and VL muscles. However, the two muscles differed in the fascicle behaviors. The MG fascicles remained same length or shortened and the VL fascicles underwent lengthening before shortening during contact. In HIGH, the TT lengthening in both muscles decreased as compared to OP (P<0.05). The rapid stretch occurred in the MG fascicles but not in VL fascicles during the braking phase. The elastic recoil ratio decreased in both muscles with increasing the intensity during DJ. These findings demonstrated that TT underwent lengthening before shortening during DJ. However, the efficacy of elastic recoil decreased with increasing the drop intensity. The effective catapult action in TT can be limited by the drop intensity. In addition, the measured muscles behaved differently during DJ, providing evidence that each muscle may have a specific way of fascicle-TT interaction.
