Objective This quantitative correlational design study aimed to examine the variation in adolescent health and lifestyle characteristics across self-reported physical activity (PA) and physical fitness (PF) levels. Methods Data were collected from 422 students (50.2% males) (16.33 SD = 1.66 y/o) attending a high school. An online questionnaire was used to gather data on the following characteristics: self-reported well-being, overall life satisfaction, depression (including self-harm and suicidal ideation), perceived health status, eating disorders, sleepiness, substance use (alcohol, tobacco and illicit drug use), body mass index, PA participation and PF levels...

BACKGROUND: International middle- and long-distance running competitions attract millions of spectators in association with city races, world championships, and Olympic Games. It is therefore a major concern that ill health and pain, as a result of sports overuse, lead to numerous hours of lost training and decreased performance in competitive runners. Despite its potential for sustenance of performance, approval of mHealth self-report monitoring (mHSM) in this group of athletes has not been investigated...

Background : Doping behavior, including the misuse of performance-enhancing drugs, is currently a serious problem in sports, and the efficacy of preventive efforts directly depends on information regarding the associations among different precipitating factors (PF) and doping behavior. This study aimed to establish the PF of potential doping behavior (PDB) in competitive swimmers. Methods : The study included 301 swimmers from Slovenia (153 females, 16.4 ± 2.4 years), tested during the 2017 National Championship...

Ibuprofen is widely used in human and veterinary medicine for the treatment of chronic pain as well as rheumatic and musculoskeletal disorders. However, the analgesic and anti-inflammatory properties of Ibuprofen have contributed to frequent drug abuse in equestrian sports. A sensitive and rapid GC-MS/MS-based method with a simple liquid-liquid extraction and derivatization requiring 200 μL volume of sample and 2 mL of extraction solvent for the simultaneous determination of ibuprofen and its metabolites was developed...

Introduction: Vascular surgeons increasingly encounter flow limitation of iliac arteries (FLIA) in endurance athletes. An experience of managing this condition is reported. Report: This is a retrospective cohort analysis of prospectively collected data at a single vascular centre. Between 2001 and 2017, 12 athletes with exercise induced pain underwent investigation and assessment. Patients with significant radiological findings (iliac kinking ± stenosis demonstrated on duplex ultrasound or catheter angiography) and dynamic flow changes (marked reduction in ankle brachial pressure indices following exertion, or increase in the common iliac artery peak systolic velocity during hip flexion on duplex) underwent surgery after trialling conservative management; the majority were open iliac shortening procedures...

BACKGROUND: In order to assess physical activity (PA) during pregnancy, it is important to choose the instrument with the best measurement properties. OBJECTIVES: To systematically summarize, appraise, and compare the measurement properties of all self-administered questionnaires assessing PA in pregnancy. METHODS: We searched PubMed, Embase, and SPORTDiscus with the following inclusion criteria: (i) the study reported at least one measurement property (reliability, criterion validity, construct validity, responsiveness) of a self-administered questionnaire; (ii) the questionnaire intended to measure PA; (iii) the questionnaire was evaluated in healthy pregnant women; and (iv) the study was published in English...

Introduction: The previous studies about exercise-related sudden cardiac arrest (SCA) have mainly focused on sports activity, but information related to SCA in other forms of physical exercise is lacking. Our aim was to identify characteristics and prognosis of SCA victims in the general population who suffered SCA during physical activity. Methods and results: We collected retrospectively all cases of attempted resuscitation in Oulu University Hospital Area between 2007 and 2012. A total of 300 cases were of cardiac origin...

Attention impairment may provide a cohesive neurobiological explanation for clusters of clinical symptoms that occur after a concussion; therefore, objective quantification of attention is needed. Visually tracking a moving target is an attention-dependent sensorimotor function, and eye movement can be recorded easily and objectively to quantify performance. Our previous work suggested the utility of gaze-target synchronization metrics of a predictive visual tracking task in concussion screening and recovery monitoring...

Background: ACL injuries are common among sports populations and achieving adequate lower extremity strength is important prior to return to play. Access to isokinetic testing equipment that measures lower extremity strength is limited. Screening tools that measure functional criteria are accessible to clinicians, however the tools' relationship to strength constructs have not been investigated in an ACL reconstructed (ACLR) population. Purpose: The primary objective was to determine if relationships exist between isokinetic peak knee extension torque (PKET), peak knee flexion torque (PKFT), hamstring to quadriceps (HQ) ratios, and YBT-LQ performance following ACLR...

Soccer refereeing is a "not-conventional" sport in which aerobic workload is prevalent. Along the years, several studies have attempted to define best markers of referees' performance. Many studies focused their attention on field tests and their relationship with aerobic power. Instead, in this study, starting by a medical assessment satisfying the FIFA 11+ criteria for injuries prevention, we have investigated the foot of soccer referees and we have also wanted to find possible and/or unexpected improvements in performance...

In physical and rehabilitation medicine, there are few reports on the effects of therapeutic low-frequency electrical stimulation on the immune response of the organism, even though electrical stimulation is used widely in clinical practice and sports medicine. The aim of our study was to examine the possible immunological consequences of moderate transcutaneous neuromuscular electrical stimulation (NMES) for quadriceps muscle strengthening in healthy individuals. The study included twelve healthy male adult volunteers (mean age 42 years) without contraindications for electrical stimulation...

BACKGROUND: Fractures of the proximal fifth metatarsal are relatively common foot injuries in elite athletes. Acute fixation with intramedullary screws is the most common operative treatment. However, the rate of nonunion and refracture after this procedure remains a concern. The purpose of this study was to determine rates of clinical and radiographic fracture healing, return to sport, and patient-reported clinical outcomes of elite athletes with proximal fifth metatarsal fracture or refracture treated with plantar plating...
