Although this slowing down will be only a tiny fraction of time, and may appear to be inconsequential, if you add up even an additional one hundredth of a second per leg landing due to insufficient hip muscle strength across an hour run, that is an additional 36 seconds for each leg across an hour run. Saving this time can be achieved not by training harder or running further, but by simply having hip muscles that are strong enough to provide adequate hip stability. In 2009, researchers found that runners who underwent six weeks of core strength training improved their 5000-metre running times when compared to those who didn’t undergo the training. The runners who participated in the research were preparing for a marathon, and underwent four sessions of five core exercises for the duration of the study. Injury minimisation and rehabilitation As with the widespread effect that running technique has on the onset of injury for runners, excessive hip motion during running represents a major injury risk factor for runners. When a runner’s hips move excessively due to hip muscle weakness, the legs of the runner will be subjected to greater loading and strain. Research has found that hip adduction (where the hip moves towards the midline of the body) and internal rotation (a collapsing in of the hip towards the runner’s midline) have been associated with knee pain and iliotibial band syndrome.Altered hip movements and reduced hip strength are common findings in females with knee pain. Research has also shown that females have a tendency to core instability, which may predispose them to greater incidence of lower extremity injury than males. In a 2004 paper, researchers found that female athletes displayed significantly decreased hip external rotation and side bridge measures compared with their male counterparts. They reported that athletes who experienced an injury over the course of a season displayed significant weakness For every hour of running, a runner will make contact with the ground 5,400 times WIN!

The 30-second article • It is important to educate running clients about the need to incorporate regular strength and conditioning exercises into their training schedules • Hip muscle stability and strength is crucial for both injury prevention and improved performance • The hip muscles stabilise the runner’s hip when the runner lands alternately on each leg • While core stability is important, many runners focus on it at the expense of hip mobility. in hip abduction and external rotation. They also concluded that hip external rotation was the sole significant predictor of injury status for the athletes they tested. They tested 80 female and 60 male athletes, many of whom were cross country runners. If you have a client who has set a goal of competing in an upcoming road or trail running event, or who is incorporating regular running into their weekly fitness regime, be sure to include strength and conditioning work of the major hip muscles. Improving the overall hip stability of a runner requires three stages: the hip muscles first need to be activated, then strengthened, with the development of hip muscle endurance thereafter.
