The human foot is characterized by a pronounced longitudinal arch (LA) that compresses and recoils in response to external load during locomotion, allowing for storage return of elastic energy within the passive structures contributing metabolic savings. Here, we examine potential active muscular contribution biomechanics deformation recoil. We test hypotheses activation three largest plantar intrinsic muscles, abductor hallucis, flexor digitorum quadratus plantae associated with muscle...
Background: A hamstring strain injury (HSI) has become the most common noncontact in soccer. Isokinetic muscle strength deficits are considered a risk factor for HSIs. However, underpowered studies with small sample sizes unable to determine associations have led inconclusive results regarding role of isokinetic and testing Purpose: To examine whether differences measures knee flexion extension represent factors injuries large cohort professional soccer players an adequately powered study...
Vertical jump performance (height) is a more representative metric for knee function than horizontal hop (distance) in healthy individuals. It not known what the biomechanical status of athletes after anterior cruciate ligament (ACL) reconstruction (ACLR) at time they are cleared to return sport (RTS) or whether vertical metrics better evaluate function.Standard marker-based motion capture and electromyography (EMG) were collected from 26 male RTS ACLR 22 control subjects during single leg...
There is an absence of high-quality evidence to support rehabilitation and return-to-sport decisions following shoulder injuries in athletes. The Athlete Shoulder Consensus Group was convened lead a consensus process that aimed produce best-practice guidance for clinicians, athletes, coaches managing sport. We developed the via 2-round Delphi (involving more than 40 content methods experts) in-person meeting. This statement provides with respect load risk management, supporting athlete...
Background To evaluate the efficacy of a single platelet-rich plasma (PRP) injection in reducing return to sport duration male athletes, following an acute hamstring injury. Methods A randomised, three-arm (double-blind for arms), parallel-group trial, which 90 professional athletes with MRI positive injuries were randomised PRP-intervention, platelet-poor (PPP-control) or no injection. All received intensive standardised rehabilitation programme. The primary outcome measure was time play,...
Acute groin injuries are common in high-intensity sports, but there insufficient data on injury characteristics such as mechanisms and clinical radiological findings.To describe these a cohort of athletes.Cross-sectional study; Level evidence, 3.A total 110 male athletes (mean age, 25.6 ± 4.7 years) with sports-related acute pain were prospectively included within 7 days from August 2012 to April 2014. Standardized history taking, examination, magnetic resonance imaging (MRI), and/or...
Hamstring injuries remain prevalent across a number of professional sports. In football, the incidence has even increased by 4% per year at Champions League level over last decade. The role muscle strength or ratios and their association with risk hamstring injury restricted small sample sizes inconclusive results.The purpose this study is to identify factors for in football players an adequately powered, prospective cohort study. Using both established (isokinetic) novel (eccentric test...
Groin injury epidemiology has not previously been examined in an entire professional football league. We recorded and characterised time loss groin injuries sustained the Qatar Stars League.Male players were observed prospectively from July 2013 to June 2015. Time injuries, individual training match play exposure by club doctors using standardised surveillance methods. incidence per 1000 playing hours was calculated, descriptive statistics used determine prevalence characteristics of...
Background There is an ongoing debate regarding the optimal criteria for return to sport after acute hamstring injury. Less than 10% isokinetic strength deficit generally recommended but this has never been documented in professional football players rehabilitation. Our aim was evaluate measurements MRI-positive injuries. Methods Isokinetic of were obtained completing a standardised rehabilitation programme. An more compared with contralateral site considered abnormal. Reinjuries within 2...
Introduction: Selection of younger athletes for advanced training in elite sport is assumed to be based on identification innate talent. Previous researchers have identified relative age effects influence these selection processes; however, maturation status and skeletal effects, which the potential a greater influence, not been widely examined.Methods: Skeletal (categorising as: early maturing, time, or late maturing via wrist hand X-ray Fels classification) birth quarter are documented 472...
Single-leg vertical and horizontal hop tests are commonly used to assess performance of healthy athletes as a measure progress during rehabilitation from knee injury. It is unclear if they similar aspects leg function, the relative joint contributions hip, knee, ankle joints propulsion landing unknown.The proportion work done by will not be same for these 2 jump types vary propulsive phases.Cross-sectional cohort study.Level 3.Twenty physically active participants completed instrumented...
We evaluated the lower limb status of athletes after anterior cruciate ligament reconstruction (ACLR) during propulsion and landing phases a single leg hop for distance (SLHD) task they had been cleared to return sport. wanted evaluate biomechanical components involved (operated) uninvolved legs with ACLR compare these those uninjured (controls).We captured standard video-based three-dimensional motion electromyography (EMG) in 26 23 healthy controls SLHD calculated trunk kinematics. joint...
Despite being the most commonly incurred sports injury with a high recurrence rate, there are no guidelines to inform return sport (RTS) decisions following acute lateral ankle sprain injuries. We aimed develop list of assessment items address this gap.We used three-round Delphi survey approach consensus opinion among 155 globally diverse health professionals working in elite field or court sports. This involved surveys that were structured question format both closed-response and...
Vertical jump tests are more sensitive in revealing asymmetries performance metrics at the time of return to sport after anterior cruciate ligament (ACL) reconstruction (ACLR) than horizontal hop tests. However, it remains unclear which vertical (bilateral or unilateral) and (kinetics performance) most effective informing rehabilitation status readiness for sport. We aimed investigate athletes during testing ACLR.A dual force platform system was used evaluate jumping 126 recreational...
Objective Most studies examining the time to return sport (RTS) after anterior cruciate ligament reconstruction (ACLR) do not account for athlete’s physical readiness. This study aimed investigate status of male athletes at 2 years ACLR, factors affecting a pivoting sports, and association between RTS subsequent knee injury risk those who met discharge criteria. Methods We prospectively followed 530 (mean age 26.7±7.7 years) participating in sports throughout rehabilitation ACLR. Pair-wise...
