Peak and Per-Step Tibial Bone Stress During Walking and Running in Female and Male Recreational Runners
In both men and women, the tibia is one of the most common sites of a bone stress injury (BSI). Women experience higher incidence of BSIs. Patients are at a heightened risk for BSIs when workloads are increased, such as when new training regimens are initiated or when run speeds are increased. Greater insight into […]
Effectiveness of Adding a Large Dose of Shoulder Strengthening to Current Nonoperative Care for Subacromial Impingement. A Pragmatic, Double-Blind Randomized Controlled Trial (SExSI Trial).
Until recently, subacromial decompression surgery was considered for treatment of subacromial impingement when nonoperative care had failed. In 2019, a strong recommendation against subacromial decompression surgery as a treatment method for subacromial impingement was issued. Such drastic changes to care pathways may leave patients without further treatment options if nonoperative care fails. Therefore, optimizing nonoperative […]
Association Between Injury Mechanisms and Magnetic Resonance Imaging Findings in Rectus Femoris Injuries in 105 Professional Football Players
Thigh injuries are the most common muscle injuries in football. In professional football, 79% of all muscle injuries occur in the thigh, of which 19% are related to the quadriceps, predominantly in the rectus femoris muscle. Despite the prevalence of rectus femoris injuries and relatively high reinjury rate (up to 17%), the current literature on […]
Plantar fasciitis is diagnosed in approximately 80% of patients with heel pain. It is triggered by collagen degeneration at the calcaneal origin of the plantar fascia attributed to repetitive microtears. Obesity is an independent risk factor for the development of plantar fasciitis and is present in up to 70% of these patients. Multiple treatment modalities […]
Feasibility and preliminary effect of anabolic steroids in addition to strength training and nutritional supplement in rehabilitation of patients with hip fracture: a randomized controlled pilot trial (HIPSAP1 trial).
Hip fracture results in large strength deficits, causing loss of function, disability and further falls. As such, a hipfracture often leads to the loss of independence, more fractures and high mortality rates, and constitutes a substantial economic burden to the health care system. Although positive effects on mobility of structured exercise interventions including strength training […]
Changes in countermovement jump performance and subjective readiness-to-train scores following a simulated soccer match
There is a complex relationship between training loads, adaptations to training and injury. While systematic exposure to high training loads protects against injury and improves the players’ fitness, each player adapts and responds differently to training and competition. This variation impacts on each player’s fitness and risk of injury. As a result, various monitoring metrics […]
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 […]
The effect of acute sleep deprivation on skeletal muscle protein synthesis and the hormonal environment
Acute and chronic sleep loss are linked with a range of negative physiological and psychological outcomes. Sleep deprivation and restriction have the potential to profoundly affect muscle health by altering gene regulation and substrate metabolism. Even relatively short periods of sleep restriction (less than a week) can compromise glucose metabolism, reduce insulin sensitivity, and impair […]
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 […]
