Knee extension maximum torque, patellar tendon CSA and length were measured with dynamometry and ultrasound imaging. An elastic knee support that has a central opening cut out for the kneecap sometimes helps. It can also be due to poor kneecap mobility or joint health. This will unlikely get better with rest, a graduated loading program is needed if it is indeed the tendon. Summary. 1 The eccentric exercise commonly recommended for the patellar tendon is the squat. Background: Previous studies suggest that tendon microcirculation response during exercises may vary based on the tendon's .

Recent studies have shown excellent clinical results using eccentric squat training on a 25 decline board to treat patellar tendinopathy. As a result, eccentric training has been a staple in many injury prevention programmes. A recent study examined the effect of contraction mode on tendon (and muscle) hypertrophy in healthy human subjects. Normally there is pain on touching the inferior pole of the patella as well as recurrent episodes of pain within the body of the tendon. 60 for example, the decline squat program involves performing 3 sets of 15 repetitions, twice daily, of single-leg eccentric squats, with an upright torso, while standing on a decline board ( figure 1 ). In a clinical trial to treat patellar tendinopathy by Cannell et al. Eccentric strength training has been thought to provide many benefits to an athlete, such as increases in strength and power output, as well as increased muscle fascicle length and tendon stiffness. tendonitis) but more current research supports the term tendinopathy. 8 this belted squat position has been previously investigated using the protocol of a 3-second eccentric contraction and a 3-second concentric contraction, with a Ad- But it is still only effective about 60-70% of the time.
