Tight hip flexors can result in lower back pain, hip pain and injury. A lot of strain is put on those muscles during activities that involve sprinting and kicking. For example, runners are more prone to hip flexor injuries because of the small, repetitive movement during running. But even if you’re not an athlete, hip flexor injuries can occur during everyday activities (for instance, slipping and falling or running to catch a bus). When those tight muscles are suddenly stretched beyond what they are accustomed to, you might also experience pain in the upper groin region, typically where the hip meets the pelvis.
Sit on the floor with your legs straight out in front of you. Bend your left knee so that your knee, shin, and foot are on the floor, parallel with your pelvis. Bend your right knee and place it on top of your left ankle so that your right knee is above your left ankle and your right ankle is above your left knee. To intensify the stretch, place your hands in front of your legs and very slowly walk them out as you lean forward. Stay relaxed and breathe. Repeat with the other leg.
Grade II (moderate): A larger tear in your muscle that makes it difficult to move and causes a moderate amount of pain, especially when you move the affected muscle, swelling, and tenderness. You may have 5 percent to 50 percent loss of function and you may be limping. You can't go back to sporting activities until the tear is completely healed. These injuries can take anywhere from a couple weeks to a few months to heal, depending on how bad they are.
The rectus femoris is one of the four quadriceps muscles -- the quadriceps are the major muscle group of the front of the upper leg. The rectus femoris attaches to the anterior inferior -- the part toward the feet -- portion of the iliac crest and runs to the base of the patella, also known as the knee. The femoral nerve supplies the rectus femoris with nerves. This is the only muscle that crosses the hip joint, which enables it to work as a hip flexor and a knee extender muscle.
You can strain or tear one or more of your hip flexors when you make sudden movements such as changing directions while running or kicking. Sports and athletic activities where this is likely to occur include running, football, soccer, martial arts, dancing, and hockey. In everyday life, you can strain a hip flexor when you slip and fall, for example.
Holland also suggests doing strength work in different planes of motion to keep all the muscles in and around your hip flexors, especially your glutes, firing correctly.“You can’t have good hip flexion if your glutes are tight or weak,” Nurse says, “so it’s super important that you’re always stretching and strengthening the front of your hip flexor and the back, which are the glute muscles.”
The hip flexor muscles flex the hip during swing. They are particularly important for initiating swing91 when walking at slow speeds. Without adequate hip flexion during swing, knee flexion is more dependent on hamstring muscle activity.59 Patients with paralysis of the hip flexor muscles attempt to advance the swing leg by either externally rotating the hip and using hip adductor muscles as hip flexors or by circumducting the leg.59,61 The effects of hip flexor muscle paralysis on gait are particularly evident when walking up stairs or slopes, which requires lifting the leg.
The good news is that there are plenty of good hip stretches out there that you can do to relieve discomfort, decrease tightness, and increase mobility in your hips. Since your hips are involved in so many of the movements you make (both inside and outside of the gym) stretching them is a great way to keep them feeling good and ready to work for you. Add some of the 12 hip stretches Atkins demos below to the end of your workout, or spend 10 minutes each day just doing a few of them, to improve mobility in your hips.
