So, piece of cake. Hi, I'm Dr. Bill Murrow. Dr. Brian Nook and I, in conjunction with Northwestern College of Chiropractic, would like to share some information with you concerning therapeutic muscle stretching in athletics. Therapeutic muscle stretching is very important, and this video is being produced with the intent of informing doctors of chiropractic, sports medicine practitioners, coaches, and athletes about the benefits of therapeutic muscle stretching in athletics. Stretching is important in athletics to increase flexibility and decrease injury. Dr. Nook and I also feel that it does enhance performance, although objective studies supporting this have not yet been performed. We recommend that these stretches be implemented in the following manner. First have the athletes do a brief warm-up, such as a lap or two around the track. Then have them perform the core stretches and the sport-specific stretches for their sport. Next, have the athletes perform their regular workout, followed again by the stretching program. After that, the athlete should then cool down. As with any exercise or stretching program, each athlete should be evaluated to make sure that therapeutic muscle stretching is indicated for them, especially if they have sustained an injury. It is also important that the athletes and coaches, and also the doctors, use good common sense when implementing therapeutic muscle stretching. Dr. Brian Nook will now demonstrate the core stretches and sport-specific stretches that we both use in our practice and with the athletic teams that we are involved with. Posterior thigh and calf stretch. Stretch position. The athlete is on their back with the leg to be stretched on the assistant's shoulder. The assistant is kneeling beside the athlete on the same side as the leg being stretched. The foot is then pulled toward the athlete, flexing the hip by the assistant. The leg is elevated until a pull is felt in the athlete's posterior thigh and calf. Contraction phase. The athlete then pushes against the assistant's shoulder with their leg and against the assistant's hand with their foot. This is held for a count of eight. One, two, three, four, five, six, seven, eight. Relaxation phase. The athlete then lowers the leg and relaxes. Antagonist contraction phase. The athlete next pulls their foot upward, locking the knee in extension, and raises their leg until they feel the stretch. The assistant then holds the leg and foot as they did in step one. The stretch is felt by the athlete in the hamstring and calf. The athlete then pushes the leg and foot against the assistant, and this starts the next set of PNF stretches. This is repeated for a total of three sets, and then the other leg is done. Push. One, two, three, four, five, six, seven, eight. Relax. Pull back. Lock the knee. Raise. Stretch. Push. One, two, three, four, five, six, seven, eight. Relax. Push. One, two, three, four, five, six, seven, eight. Relax. Pull back. Lock the knee. Raise. And stretch. Relax. Groin adductor stretch. Stretch position. The athlete is lying on their back with their legs spread apart as far as possible. The assistant then steps between the athlete's legs with their feet inside the athlete's thighs just above the knees. The assistant then spreads the athlete's legs apart until the stretch is felt inside the athlete's thighs. The assistant then squats slightly, increasing the stretch. Contraction phase. The athlete then pushes against the assistant's legs for a count of eight. One, two, three, four, five, six, seven, eight. Relaxation phase. The assistant then steps out from between the athlete's legs and the athlete pulls their legs together. Antagonist contraction phase. The athlete then pulls their legs apart as far as possible. Stretch phase. The assistant then steps between the athlete's legs above the athlete's knees and the assistant then squats and repeats the stretch. The athlete then pushes against the assistant's legs again, starting the next set of stretches. This is repeated for a total of three sets. Push. One, two, three, four, five, six, seven, eight. Relax. Legs together. Spread them. Push. One, two, three, four, five, six, seven, eight. Relax. Together. Spread them. Stretch. Relax. Lateral leg. Abductors. Stretch position. The athlete is lying on their back. Their legs will then be crossed. The assistant steps between the athlete's feet, stretching the outside of the athlete's legs further. Contraction phase. The athlete then pushes against the assistant's legs, trying to uncross their legs. This will be, there will be more of a stretch on the top leg. This is performed for a count of eight. One, two, three, four, five, six, seven, eight. Relaxation phase. The assistant then steps out from between the athlete's legs and the athlete uncrosses their legs as far as possible. Antagonist contraction phase. The athlete then recrosses their legs with the opposite leg on top. Stretch phase. The assistant then steps between the athlete's crossed legs until the stretch is again felt. The athlete then pushes against the assistant's legs, again starting the next set of stretches. This is repeated for a total of three sets. Ready, push. One, two, three, four, five, six, seven, eight. Relax. Cross. Push. One, two, three, four, five, six, seven, eight. Relax. Cross. Stretch. Relax. Buttock and piriformis stretch. Stretch position. The athlete is lying on their back and crosses one leg over the other with the bottom of the foot on the crossing leg on the floor next to the opposite hip. The assistant then kneels next to the athlete's foot on the floor. The assistant places one knee next to the side of the athlete's foot and then pushes the athlete's flex knee up toward the shoulder of the athlete on the same side. The assistant then places their other foot next to the athlete's straightened knee in order to separate the athlete's foot and knee. The assistant then leans their chest into the athlete's leg, pushing the crossed leg and knee toward the athlete's opposite shoulder until the athlete feels a stretch in the crossed leg buttock. Contraction phase. The athlete then pushes their crossed knee out against the assistant's chest for a count of eight. One, two, three, four, five, six, seven, eight. Relaxation phase, the assistant and athlete stop pushing. The athlete does not uncross their leg but relaxes in a stretch position. Antagonist contraction phase. The athlete then pulls their knee farther up toward the opposite shoulder until they feel a stretch in their buttock. Stretch phase. The assistant then moves their knee that is against the athlete's foot up toward the athlete's shoulder and then leans into the athlete's leg, moving it up toward the athlete's opposite shoulder. This is done until a stretch is felt again in the athlete's buttock. The athlete then pushes out against the assistant's chest again, starting the next set of PNF stretches. This is repeated for a total of three sets and then the opposite leg is done. Push, one, two, three, four, five, six, seven, eight. Relax. Push, one, two, three, four, five, six, seven, eight. Relax. Anterior leg. Quadriceps and anterior shin stretch. Stretch position. The athlete is positioned on their stomach with their legs fully extended and together. The assistant then kneels beside the leg to be stretched. The athlete's leg is flexed, pushing their foot toward the buttock. The assistant then blocks the athlete's foot with their hands. The athlete's foot is plantar flexed, causing the foot to be pointed. The assistant then grasps the athlete's bent knee and lifts it off the floor until the athlete feels a stretch in their quadriceps and anterior shin. The assistant must make sure not to let the athlete's flexed knee move out to the side and must be kept in the midline. The assistant should stabilize the athlete's lower back by placing their forearm across the athlete's belt line. Contraction phase. The athlete then pushes their foot out against the assistant's shoulder for a count of eight. One, two, three, four, five, six, seven, eight. Relaxation phase. The athlete then straightens their leg out and relaxes. Antagonist contraction phase. The athlete then points their toe and flexes the knee, trying to touch their heel to the buttock. Stretch phase. The assistant then puts their shoulder against the athlete's toes and grasps the flexed knee, lifting the knee off the floor until a stretch is felt in the athlete's quadriceps and anterior shin. The athlete then pushes against the assistant's shoulder again, starting the next set of PNF stretches. This is repeated for a total of three sets, and then the other leg is done. Ready? Push.

The next sports-specific stretch for basketball is the anterior shin stretch. To perform this stretch, the athlete is seated on the floor with their legs out in front of them. The assistant is kneeling in front of the athlete. The assistant holds both of the athlete's feet at the arch and pushes the athlete's foot down to point the toes. The athlete's foot is turned out until a stretch is felt on the inside of the shin. The athlete then pulls up with their feet for a count of eight. One, two, three, four, five, six, seven, eight. The athlete and assistant then relax and allow the athlete's feet to resume a neutral position. The athlete then points their toes and turns their feet out again. The assistant then contacts the athlete's arch again and pushes their feet, pointing their toes and turning their feet outward until a stretch is felt on the inside of the shin by the athlete. The athlete then pulls against the assistant's hands, starting the next set of PNF stretches. This is repeated for a total of three sets. Ready? Push. One, two, three, four, five, six, seven, eight. Relax. Down. Push. One, two, three, four, five, six, seven, eight. Relax. Down. Relax. For wrestling, use the core stretching program and the back extensor stretch, as previously described for football. For track and field athletes, we recommend the core stretching program and the anterior shin program, as previously demonstrated for basketball. The baseball stretches consist of the core stretching program, the tricep stretching program, as previously demonstrated with basketball, and the posterior shoulder stretch. To perform the posterior shoulder stretch, the athlete flexes their elbow and brings their arm across their body, reaching for the opposite shoulder. The assistant then stands behind the athlete and holds above the athlete's elbow. The athlete then rotates their thumb outward. The assistant then pulls the athlete's elbow across the athlete's chest until a stretch is felt in the posterior aspect of the athlete's shoulder. The athlete then pulls their arm back across their chest while trying to turn their arm outward against the assistant for a count of eight. One, two, three, four, five, six, seven, eight. The athlete relaxes their arm to their side and then holds their arm inward. The athlete then reaches across the shoulder again to their opposite side. The assistant again holds the athlete's elbow and pulls it further across the athlete's chest until a stretch is felt in the posterior aspect of the athlete's shoulder. The athlete then pulls their arm back up against the assistant's hands, starting the next set of PNF stretches. This is repeated for a total of three sets, and then the other shoulder may be done. Ready, pull. One, two, three, four, five, six, seven, eight. Relax. Ready, pull. One, two, three, four, five, six, seven, eight. Relax. Relax. For softball, we recommend the core stretching program and two additional stretches. The first stretch is the triceps stretch, as previously demonstrated with basketball. The second stretch is the posterior shoulder stretch, as previously demonstrated with baseball. The swimming stretching program consists of the core stretching program, except that the anterior chest and anterior arm stretch are not done due to the risk of developing anterior shoulder instabilities.
