Report Urges Runners to Treat Post-Run Stretching and Recovery as Part of Training

The report says the areas that are actually tight and prone to soreness after running are the front of the thighs, the glutes, the back of the calves and the deep hip flexor iliopsoas, not only the hamstrings. Each push-off engages the front thighs, glutes and calves, while each landing forces the quadriceps to contract eccentrically to brake the body and absorb impact. If the iliopsoas is not stretched, the report says, the glutes can become harder to activate and the muscle can pull the lumbar spine forward, increasing anterior pelvic tilt and possibly causing low back pain.

For the front thighs, the report describes a stretch in which the hand moves from the toes to the ankle, the ankle is brought toward the glutes, the inner thighs are brought close together, and the stretched thigh moves backward. The opposite arm can be extended for balance, or a wall or tree can be used for support. For the glutes, a seated figure-four-like stretch is recommended: sit on a step or park bench, place the left ankle over the right thigh, push the left knee toward the ground with the left elbow, keep the upper body upright, and hinge forward from the hips without rounding the back. For the calves, the report suggests using a wall or step, placing the left foot forward and bringing the calf close to the wall. For the iliopsoas, it recommends a lunge-like position with the front leg about one shoulder-width forward, keeping the pelvis neutral and vertical over the line between the feet, then inhaling toward the pelvis to feel a strong stretch; the diaphragm is the main breathing muscle and coordinating with breath improves the stretch. A common error, the report says, is failing to move through the steps and failing to breathe with the movement.

Effective stretching should last at least 30 seconds, according to the report, rather than a few seconds. It suggests setting a countdown with a phone assistant or taking six deep breaths, relaxing further on each exhale and trying to increase the range. The report also says fascia cannot be ignored. Fascia is the white connective tissue that wraps muscles; if it is tight or has knots, stretching may only lengthen compensating areas while the knots remain contracted. Knots can also pull muscles back after stretching. The report recommends using a foam roller once a week to roll the whole body, applying extra pressure on painful spots for about 30 seconds and continuing after the pain decreases.

The rolling sequence in the report starts at the back of the calves and moves up to the back of the thighs, then rolls the left glute with one leg crossed over, before switching sides. The runner then turns prone to release the front thighs. After that, the left thigh is placed on the roller while the body moves side to side, massaging the left thigh and outer thigh at the same time; after 30 seconds, the other side is done. Finally, kneeling on the roller can release the front thighs. After foam rolling, the report recommends mat stretches: from a plank position, bring the left knee between the hands, lay the left lower leg flat on the mat, lower the body while keeping the left pelvis close to the ground and trying to bring the right pelvis toward the ground to stretch the left glute. After 30 seconds, keep the lower body still, lift the upper body, hook the right leg, hold the right ankle with the right hand and fold forward to stretch the front thigh. After switching sides, return to the plank, push the body back and sit on the heels to stretch the calves and arches.

For runners who are too tired to stretch after a run, the report suggests integrating recovery into daily routines. They can sit on a chair and use an elbow as a foam roller on the front thighs, press the left calf against the right knee for point massage, and then stretch the glutes in a figure-four position. When using an elbow, the report says, press into the deep muscle first and then roll; otherwise, the movement only rubs the skin. Similarly, when using the right knee to massage the left calf, press the left knee down on the right knee before moving back and forth.

Recovery is not limited to stretching. After high-intensity running, such as when heart rate exceeds 170 beats per minute, or long-distance running, the report says runners should not stop immediately. They should gradually reduce intensity and cool down to help clear lactate from the blood. Nutrition and sleep are also important. Runners should pay attention to glycogen replenishment, which is a key fuel for running, especially long-distance running; after a 20-kilometer run, the report's author adds half a bowl of rice to help restore muscle glycogen. The report also advises attention to multivitamins and calcium for bone health and to prevent stress fractures in the calves. On sleep, the report notes that excess post-exercise oxygen consumption and higher body temperature can make it harder to fall asleep. It says running should ideally avoid the evening; night runners should finish at least four hours before bed or lower the sleeping environment's temperature. When training volume is high, sleep should be extended: for every extra hour of exercise, add 30 minutes to the usual eight hours of sleep.

The report says many runners plan every kilometer but treat post-run stretching and recovery as a dispensable ending. It argues that this ending determines whether the next day feels light or sore, and that training progress is completed during recovery, not during running itself. It advises giving the body more than ten minutes after a run to stretch and relax. The report also says that reducing prolonged sitting is important for health, citing back pain, wrist pain and increased risks of hypertension and diabetes, and it mentions a sedentary health guide based on exercise science principles.
