Foot strike patterns and running-related injuries among high school runners: a retrospective study.

There is a possible relationship between foot strike patterns and running-related injuries; however, this relationship among high school runners remains uninvestigated. Therefore, this retrospective cohort study examined this relationship among high school runners. Overall, 123 male Japanese high school runners participated in this study and completed a questionnaire regarding their characteristics, running habits, and running-related injury histories. We filmed their habitual high-intensity training sessions from a lateral side. Participants' foot strike patterns were visually classified, and they were divided into the non-rearfoot strike (forefoot strike and midfoot strike) and rearfoot strike groups. An independent sample t-test or Welch's t-test was used to compare participant characteristics, running habits, the number of running-related injuries in the past 1 year, and the running speed at the filmed training sessions between both groups. A χ2 test was used to examine the relationship between running-related injury histories and foot strike patterns in both groups. The number of running-related injuries in the past 1 year was not significantly different between both groups; however, running-related injury incidence was significantly associated with non-rearfoot strike (P<0.05). Furthermore, non-rearfoot strike was significantly associated with a history of achillodynia (P<0.05). Other running-related injuries, such as medial tibial pain, lateral knee pain, and heel pain, were not significantly associated with foot strike patterns. Our study revealed that rearfoot strike runners did not have a higher risk of running-related injury compared to that of non-rearfoot strike runners, and that non-rearfoot strike was associated with achillodynia.

Adolescent Running Biomechanics - Implications for Injury Prevention and Rehabilitation.

Global participation in running continues to increase, especially amongst adolescents. Consequently, the number of running-related injuries (RRI) in adolescents is rising. Emerging evidence now suggests that overuse type injuries involving growing bone (e.g., bone stress injuries) and soft tissues (e.g., tendinopathies) predominate in adolescents that participate in running-related sports. Associations between running biomechanics and overuse injuries have been widely studied in adults, however, relatively little research has comparatively targeted running biomechanics in adolescents. Moreover, available literature on injury prevention and rehabilitation for adolescent runners is limited, and there is a tendency to generalize adult literature to adolescent populations despite pertinent considerations regarding growth-related changes unique to these athletes. This perspective article provides commentary and expert opinion surrounding the state of knowledge and future directions for research in adolescent running biomechanics, injury prevention and supplemental training.

Factors influencing the occurrence of pain and injury in runners

Background: With the growth of running popularity, the number of running-related injuries has risen. Longterm training and inadequate training loads are only a few factors causing overload injuries amongst runners. Aim of the study: To determine factors influencing the onset of pain and injury in runners. Material and methods: The study involved 150 runners aged 17-64 years (mean age: 30 ± 10 years) and was conducted via a questionnaire containing questions concerning, for example, training frequency, location of pain, type of trauma, treatment and rehabilitation. Results: 38% (n = 57) of runners often felt pain during training. 41% of them (n = 23) reported pain after running short distances and it was most frequently located in the knee joints (26%, n = 15). 48% (n = 72) experienced a running injury. The largest percentage of these (36%, n = 26) were related to knee injuries. As factors causing injuries, the interviewees mentioned one-sided training plan (24%, n = 17), overtraining (24%, n = 17), and insufficient warm-up (16%, n = 12). The analysis of the results has shown a statistically relevant positive correlation (r = 0.177, p &lt; 0.05) between weekly frequency of training and the number of injuries sustained in the last year. The higher the weekly frequency, the more often injures occur amongst runners. Conclusions: The study shows that the occurrence of pain and injury depends on many factors. A frequent cause of any disturbances within the musculoskeletal system is overloaded soft tissue caused by overtraining. Lower limbs, particularly knee joints, are mostly at risk.

The Effect of a Hip-Strengthening Program on Mechanics During Running and During a Single-Leg Squat

Block randomized controlled trial. To investigate whether a strengthening and movement education program, targeting the hip abductors and hip external rotators, alters hip mechanics during running and during a single-leg squat. Abnormal movement patterns during running and single-leg squatting have been associated with a number of running-related injuries in females. Therapeutic interventions for these aberrant movement patterns typically include hip strengthening. While these strengthening programs have been shown to improve symptoms, it is unknown if the underlying mechanics during functional movements is altered. Twenty healthy females with excessive hip adduction during running, as determined by instrumented gait analysis, were recruited. The runners were matched by age and running distance, and randomized to either a training group or a control group. The training group completed a hip strengthening and movement education program 3 times per week for 6 weeks in addition to single-leg squat training with neuromuscular reeducation consisting of mirror and verbal feedback on proper mechanics. The control group did not receive an intervention but maintained the current running distance. Using a handheld dynamometer and standard motion capture procedures, hip strength and running and single-leg squat mechanics were compared before and after the strengthening and movement education program. While hip abductor and external rotation strength increased significantly (P<.005) in the training group, there were no significant changes in hip or knee mechanics during running. However, during the single-leg squat, hip adduction, hip internal rotation, and contralateral pelvic drop all decreased significantly (P = .006, P = .006, and P = .02, respectively). The control group exhibited no changes in hip strength, nor in the single-leg squat or running mechanics at the conclusion of the 6-week study. A training program that included hip strengthening and movement training specific to single-leg squatting did not alter running mechanics but did improve single-leg squat mechanics. These results suggest that hip strengthening and movement training, when not specific to running, do not alter abnormal running mechanics. Therapy, level 2b.

The GRONORUN 2 study: effectiveness of a preconditioning program on preventing running related injuries in novice runners. The design of a randomized controlled trial

BackgroundDistance running is a popular recreational exercise. It is a beneficial activity for health and well being. However, running may also cause injuries, especially of the lower extremities. In literature there is no agreement what intrinsic and extrinsic factors cause running related injuries (RRIs). In theory, most RRIs are elicited by training errors, this too much, too soon. In a preconditioning program runners can adapt more gradually to the high mechanical loads of running and will be less susceptible to RRIs. In this study the effectiveness of a 4-week preconditioning program on the incidence of RRIs in novice runners prior to a training program will be studied.Methods/DesignThe GRONORUN 2 (Groningen Novice Running) study is a two arm randomized controlled trial studying the effect of a 4-week preconditioning (PRECON) program in a group of novice runners. All participants wanted to train for the recreational Groningen 4-Mile running event. The PRECON group started a 4-week preconditioning program with walking and hopping exercises 4 weeks before the start of the training program. The control (CON) and PRECON group started a frequently used 9-week training program in preparation for the Groningen 4-Mile running event.During the follow up period participants registered their running exposure, other sporting activities and running related injuries in an Internet based running log. The primary outcome measure was the number of RRIs. RRI was defined as a musculoskeletal ailment or complaint of the lower extremities or back causing a restriction on running for at least three training sessions.DiscussionThe GRONORUN 2 study will add important information to the existing running science. The concept of preconditioning is easy to implement in existing training programs and will hopefully prevent RRIs especially in novice runners.Trial registrationThe Netherlands National Trial Register NTR1906.

No Effect of a Graded Training Program on the Number of Running-Related Injuries in Novice Runners

Background Although running has positive effects on health and fitness, the incidence of a running-related injury (RRI) is high. Research on prevention of RRI is scarce; to date, no studies have involved novice runners. Hypothesis A graded training program for novice runners will lead to a decrease in the absolute number of RRIs compared with a standard training program. Study Design Randomized controlled trial; Level of evidence, 1. Methods GRONORUN (Groningen Novice Running) is a 2-armed randomized controlled trial comparing a standard 8-week training program (control group) and an adapted, graded, 13-week training program (intervention group), on the risk of sustaining an RRI. Participants were novice runners (N = 532) preparing for a recreational 4-mile (6.7-km) running event. The graded 13-week training program was based on the 10% training rule. Both groups registered information on running characteristics and RRI using an Internet-based running log. The primary outcome measure was RRIs per 100 participants. An RRI was defined as any musculoskeletal complaint of the lower extremity or back causing a restriction of running for at least 1 week. Results The graded training program was not preventive for sustaining an RRI (χ 2 = 0.016, df = 1, P = .90). The incidence of RRI was 20.8% in the graded training program group and 20.3% in the standard training program group. Conclusions This randomized controlled trial showed no effect of a graded training program (13 weeks) in novice runners, applying the 10% rule, on the incidence of RRI compared with a standard 8-week training program.
