Knee pain is very common, so common in fact that 1 in 4 adults will suffer knee pain. Knee pain can occur in high-level athletes and in the general population. The long arc quad exercise is the easiest and most effective exercise for all skill levels.
Long arc quads strengthen the quad muscle which is the muscle of the front of your thigh. Long arc quads can be performed in the seated position either on a chair or by sitting at the edge of a surface or bed.
Prior to starting any exercise program, you should get advice of a doctor about your specific condition. If your health care provider suggests physical therapy it is best to perform this exercise with a physical therapist so that they can evaluate you and provide you with the cues for the proper form. This exercise along with other physical therapy exercises will improve the strength of the muscle.
Who Should Perform Long Arc Quad?
Anyone who wants to strengthen their quadriceps muscles or reduce knee pain should perform this exercise. This exercise is commonly recommended for patients after a knee surgery such as a knee replacement surgery. This exercise is commonly recommended because it strengthens the quadriceps muscles without putting too much pressure on the knee joint like other more aggressive exercises do like deep squats.
What Is The Purpose Of Long Arc Quad?
The purpose of the long arc quad exercise is to strengthen the quadriceps muscles. When the quadriceps muscles are weak, there is more stress that is put on the knee joint. This additional stress to the knee joint can cause knee pain.
What Is The Difference Between Long Arc Quad And Short Arc Quad?
The difference between a long arc quad and a short arc quad is the range of motion performed in each exercise. The long arc quad works on the full knee range of motion typically 0-90 degrees, while the short arc quad exercise works on a smaller range and the terminal knee extension. Although both exercises strengthen the quadriceps muscles, they do so in different ranges.
The long arc quad works the quadriceps muscle from a larger range of motion than the short arc quad exercise. It works from 0 to 90 degrees. Although this larger range of motion is good for muscle strengthening, it may be too aggressive for some patients.
The short arc quad exercise also works the quadriceps muscles but from a smaller range of motion. The short arc quad exercise works terminal knee extension or the last 15-20 degrees of the knee. This exercise typically places less stress on the knee joint and is a good alternative if the long arc quad exercise is painful.
Physical Therapy Exercises
Physical therapy is the best conservative way to fix knee pain. Both the long arc quad exercise and the short arc quad exercise will strengthen the quad muscles. These physical therapy exercises can be performed in both the seated and lying down positions.
Long Arc Quad Exercise
Start by sitting on a chair with your feet flat on the floor. You should have your feet hip-width apart. Now slowly start straightening your knee until it is fully straight. When your leg is as high as it will go with your leg straight you will tighten your quad muscle. Hold this position for 5 seconds and then slowly bring your leg back down.
Long Arc Quad Exercise Progression
- Active Assist Version Of Long Arc Quad
- If this exercise is too difficult you can perform this exercise without the hold. If your muscles are too weak to actively lift your leg up by yourself then you can use your other foot to help assist it into that motion.
- Start by placing your opposite foot underneath your ankle. Now start straightening your knee and use your opposite leg to help assist your leg until it is fully straight.
- Progression of Long Arc Quad With Ankle Weight
- If the long arc quad exercise is too easy you can add either an ankle weight or resistance band around your ankles.
- Place an ankle weight around your ankle. Now perform the exercise the same way as the standard version. You can buy adjustable ankle weights here.
- Long Arc Quad With Band
- If you perform the resistance band version you will place a resistance band around both of your ankles. You will now keep your good foot down on the ground and lift your opposite leg until it is fully straight
- As you kick your leg up you will feel the resistance in the band. After your knee is fully straight you will now slowly bend it back down to the original position. Be sure to slowly control this motion instead of allowing the resistance band and gravity to bring your leg down.
- You can buy resistance bands with different resistance levels here.
