Which exercise is considered contraindicated due to its potential to stress the patellar tendon?

The hurdles stretch is identified as contraindicated due to its potential to cause stress on the patellar tendon. This stretch typically involves a position where the knee is extended while trying to reach for the foot, which can place excessive strain on the patellar tendon, especially for individuals who might already have underlying knee issues or tendinopathy.

The movement required in the hurdles stretch can lead to abnormal loading patterns on the knee joint, which heightens the risk of aggravating the tendon and potentially leading to pain or injury.

In contrast, other stretches like the quad stretch or hamstring stretch generally focus on improving flexibility without placing undue stress on the knee joint. The African squat may also be a more natural movement that does not usually provoke patellar tendon stress when performed correctly.
