These are the same muscles that fire up during the first strides of sprint acceleration, particularly the initial 10 steps. The hip extensors and the hip flexors are the strongest muscle groups within the lower extremity. This places your foot in a position where it’s ready to strike the ground again. If, for example, you looked at your watch and saw 2:53:40 with one mile to go in a marathon, you’d start driving your legs and pushing off harder each stride to try to sneak under the three-hour mark. Since the foot lands so far in front of the body, a heelstrike is pretty much mandatory, but the footstrike is not so much the problem as is the position of the foot relative to the body. The genetic makeup of an athlete may bless them with natural speed, but if efforts are not made to improve technique, they will never reach their full potential. In running gait, we need this triple extension to be driven top-down from the hip, with gluteus maximus and the hamstrings contracting powerfully to drive the femur (thigh bone) backwards from the hip. Perform lying leg raises and knee drives off a step. The authors concluded, “Potentially beneficial effects were observed for the hip thrust compared to the front squat in 10- m and 20- m sprint times.” Some coaches like Latif Thomas recommend punching the ground in a powerful yet forceful way to increase speed.Remember the pendulum in the Grandfather clock? Hip thrusts target your hip extension muscles—particularly the glutes. While not so much an injury concern, an inability to generate power at the hips is an affliction that comes with a serious performance detriment, particularly when it’s time to kick it into high gear in a race. The hip joints are rotating around the imaginary centerline of your body parallel to your spine at about the elevation of the sacrum. It is not a perfect rotation, as the free leg hip will come through higher than the support leg’s hip if the lateral chain is firing correctly. Focusing on hip drive when doing your strides and possibly incorporating some bounding and skipping a few times a week will go a long ways towards improving your ability to generate power from the hips. Sprinting. Contract your hip flexors and swing your leg up toward your chest as soon as your foot leaves the ground. Bend your knee and drive your hip up until it’s bent to 75 to 90 degrees. Proper Running Form: Does Gravity Help You Run Faster? How high your hip flexors can drive your knee to your chest is partly dependent on the flexibility of your hamstrings and glutes. Please check with the appropriate physician regarding health questions and concerns. Although the sprints are events in themselves, the ability to sprint is an essential weapon in an athlete's armoury for many track and field events and many sports. Hips crucial role in any hinging movement in lifting, such as deadlifts, cleans and snatches. Probably most of us have seen riders who´s bike squirrel from side to side when sprinting. Since hip drive is most important when you are running fast or trying to accelerate, it makes the most sense to practice it while actually moving at a fast pace. The knee drive off a step involves placing one foot on a step and then maintaining that foot on the step as you pick up and drive the opposite knee up toward your chest.

The start of push is describe when the hip is over the knee or slightly in front of the knee. The gluteus maximus and hamstrings work together to explosively extend your hip joints as you drive your foot into the ground to propel yourself forward. In terms of specific drills, there are all sorts of technique specific movements that can easily be incorporated into warm-ups. Incorporate regular sessions of hamstring and glute stretching into your regimen. Strengthening the Hip Flexors for Sprinting Speed. When the ball of the lead foot leaves the ground, the drive phase is completed (6, 10, 23). Your upper thigh will move beyond parallel to the track during the knee drive phase. The contribution from the glutes and hamstrings during sprinting receives a significant amount of attention from coaches and strength and conditioning professions. Pump your arms as fast as possible. Improving your hip drive should give you noticeably more “pop” in your stride when you are running fast, and might save the day in a final-straight sprint. Elements addressed in this article include, accelerative sprinting, maximum velocity sprinting, the break-down of a sprint across 100m, ground contact time, movement mechanics, reactive forces, and perfecting the sprint start. Prior to writing full-time, she worked as a strength coach, athletic coach and college instructor. 1. This week, we’re going to be looking at an issue of running form that’s relevant to just about everybody – how to run with more power. You don’t have to be an expert to understand that sprinters must develop strength in large muscle groups, such as the quadriceps, hamstrings and calves.

The research group included one individual who sold hip thrust benches. Keep your hips square to the direction you’re running as you lift your leg, not allowing your pelvis to rotate or twist. Since the hamstrings are involved in hip extensions and deceleration of the lead leg, even a minor tightness issue can lead to sub-par power output and an increase chance of injury. Generating power at the quads is fine, but focusing on that to the exclusion of hip power proves to be a big problem. Most people picture power being generated in the running stride when the foot pushes off the ground, which is correct. If you take a look at the glute max muscles on a sprinter, this should be no surprise! The men increased their hip flexor strength by 11.4% and the women by 14.3%. The ball of the foot should land before the heel. Tight muscles will adversely affect the knee drive. The short period of surface contact should continue until the athlete’s center of gravity passes over and in front of the lead foot.
