![]() 2 Unfortunately, athletes who have undergone ACL reconstruction are at relatively high risk for sustaining another ACL injury after returning to sport (compared to athletes without a history of ACL injury). 1 Surgical reconstruction of the ACL is commonly recommended for athletes who plan to resume sports participation. This may help to explain the relatively high injury rates for the uninvolved limb in athletes who have returned to sport following anterior cruciate ligament reconstruction.Īnterior cruciate ligament (ACL) tears are common among young athletes who compete in sports that involved frequent landing and jumping, such as basketball. The athletes in this study consistently applied higher and more rapid loads to their uninvolved limb over multiple land-and-jump cycles. Impact forces, loading rates, and propulsive forces were higher for the uninvolved limb, compared to the involved limb, over the five land-and-jump cycles analyzed. There was not a limb-by-cycle interaction effect or main effect of cycle for the impact forces, loading rates, or propulsive forces however, there was a main effect of limb for the impact forces (F(1, 8) = 14.64 p=0.005), loading rates (F(1, 8) = 5.60 p=0.046), and propulsive forces (F(1, 8) = 10.38 p=0.012). Two-way analysis of variance, for within-subjects factors of limb and cycle, was performed for the impact forces, loading rates, and propulsive forces from the first five land-and-jump cycles completed. Athletes performed a repetitive tuck jump task for 10 seconds, while ground reaction forces were recorded for their uninvolved and involved limbs via separate force platforms. All participants had undergone successful unilateral anterior cruciate ligament reconstruction, had completed post-operative rehabilitation, and were in the process of completing return-to-sport testing. ![]() Nine athletes (four males, five females) participated in this study. ![]() The purpose of this study was to examine bilateral landing and jumping kinetics during performance of a repetitive tuck jump task in athletes who had undergone anterior cruciate ligament reconstruction and completed rehabilitation. However, previous studies have only examined forces and loading rates for tasks involving an isolated land-and-jump. their limb that underwent reconstruction), which may place their uninvolved limb at risk for injury. Remember that at the bottom position, the hips should always be below the knees.Īt the top position of the jump, try to touch your chest with the knees but if you can’t, your knees must still remain higher than the hips.Ī good routine for Tuck Jumps is to do several sets of 5 jumps and rest 2 minutes in between sets for maximum recovery.Athletes who have undergone anterior cruciate ligament reconstruction typically exhibit relatively high/rapid loading of their uninvolved limb during bilateral landing and jumping (vs. Tuck Jump is combining a bodyweight Squat with a jump. ![]() Repeat the exercise until you have completed the targeted number of reps.Reset your position then begin the next rep by dropping again to the bottom position of the squat. Land on the balls of your feet and stabilise your body.Use your arms to drive your body up and get higher elevation. Explode up and off the floor by pushing your feet through the floor, extending the knees and pushing your hips forward to drive your knees toward the chest.At the bottom position, your knees must be directly on top of your feet and your hips below your knees.Slowly descend to the bottom position of the squat.Bend you arms slightly and keep them alongside your hips.Push your hips slightly back and your chest out to maintain a flat back position. Stand in a shoulder width position, angle your feet slightly out.Tuck Jumps is a valuable exercise if you participate in activities that require power, speed and explosiveness. Tuck Jumps can be used as a plyometric exercise to develop power and speed or to prime up the hip flexors and leg muscles before performing leg and back workouts. Tuck Jumps exercise is an explosive exercise that works the core section primarily the rectus abdominis and transverse abdominis but also engages the quadriceps, gluteus muscles, hamstrings and calf muscles.
