Lower step rate is associated with a higher risk of bone stress injury: a prospective study of collegiate cross country runners.
Bone stress injuries (BSIs) are very common among collegiate cross country runners, occurring at a rate of 16 and 29 BSI per 100 000 athletic exposures for men and women, respectively. The average recovery time following a BSI in this population is 13 weeks. Therefore, identification of risk factors for BSI is vital fordeveloping injury […]
Leg Stiffness, Joint Stiffness, and Running-Related Injury. Evidence From a Prospective Cohort Study.
Many aspects of human running can be well approximated using a spring-mass model, in which the legs behave like a spring, storing and releasing mechanical energy during contact with the ground. Leg and joint stiffness models have successfully explained many facets of human gait. Given that leg and joint stiffness are biomechanical constructs that incorporate […]
A review of the role of lower-leg strength measurements in ankle sprain and chronic ankle instability populations
Ankle injuries are common during sport activities and account for a large percentage of time loss as a result. Strength training exercises targeting the prime movers including the plantar flexors, dorsiflexors, invertors, and evertors of the foot and ankle complex form the foundation of ankle injury rehabilitation. These exercises are used in conjunction with other […]
Do Injury-Resistant Runners Have Distinct Differences in Clinical Measures Compared to Recently Injured Runners?
Runners are subject to a high incidence of lower extremity injury of between approximately 20% to 80%. Clinical measures of muscle strength, functional foot alignment and joint motion have been suggested to be related to loading and to injury itself. Imbalances in factors such as tissue strength and joint motion may be a precursor to […]
Modular control of muscle coordination patterns during various stride time and stride length combinations.
The adjustment of stride time and stride length combinations (stride time-length combinations) is fundamental for generating various walking patterns, such as slow walking by a long stride length or rapid walking by a short stride length. Various walking patterns contribute to obstacle avoidance and adaptation to unstable surfaces. Humans might generate various walking patterns via […]
Performance-Based Outcomes After Anterior Cruciate Ligament Reconstruction in Professional Athletes Differ Between Sports.
Athletes undergo anterior cruciate ligament reconstruction (ACLR) and subsequent rehabilitation with the goal of returning to full function afterward. While excellent outcomes have been previously reported after ACLR inprofessional athletes of individual sports, it is unknown how these differ across sports. Furthermore, because of the high level of performance that is required to return to […]
Shoulder extension strength: a potential risk factor for shoulder pain in young swimmers? The shoulder is the most frequent site of pain and time loss injury in swimmers, In all cohorts, shoulder pain prevalence in swimmers is high, increasing with time in the sport and may range from 40 to 91% depending on the age […]
Injury risk during running is associated with high-weekly training distance as well as lack of running experience, putting both competitive long-distance runners and novice runners at risk of developing overuse injuries. The development of overuse injuries has been associated with kinematic variables of all lower limb joints. Some of these variables, such as increased ankle […]
Though the incidence of stress fractures in the military is almost half of that of elite athletes (12% vs 21%), recruits who sustain stress fractures are four times more likely to be discharged from training programs and are at a higher risk for sustaining a subsequent stress fracture. Rehabilitation from stress fractures requires personnel and […]
