OBJECTIVE: Injuries with varying degrees of temporary or permanent visual dysfunction are common in boxing. This study presents clinical diagnostic information regarding the functional integrity of the visual system in elite amateur boxers. The objective of this study was to assess the presence of normal or abnormal pattern visual evoked potentials (VEP). VEP in boxers were analyzed in relation to the non-athletic group and years of boxing activity. METHODS: Clinical examination involved 31 boxers (21 male and 10 female) and 31 controls homogeneous in terms of age and gender...

OBJECTIVES: The anterior talofibular ligament (ATFL) is the most frequently injured ligament during inversion strains of the ankle. The purpose of this study was to evaluate the feasibility of acoustic radiation force impulse (ARFI) elastography and to determine the in vivo mechanical properties of the ATFL in healthy athletes. METHODS: Sixty healthy athletes (32 female, 28 male; 28.9 ± 2.1 years) were recruited from the medical and sports faculty. ARFI values, represented as shear wave velocities (SWVs) as well as conventional ultrasound were obtained for the ATFL in neutral ankle position...

BACKGROUND: Medial patellofemoral ligament (MPFL) reconstruction is an increasingly utilized surgical option for recurrent patellar instability. Recent studies have highlighted the potential benefits of accelerated functional rehabilitation; however, no validated MPFL rehabilitation guidelines currently exist. OBJECTIVE: To assess the variability of MPFL reconstruction rehabilitation protocols published online by academic orthopaedic programs. METHODS: Online MPFL rehabilitation protocols from U...

Despite evidence that strength and conditioning (S&C) programs decrease injury risk and increase sport performance, young females are rarely offered S&C programs comparable to those of their male counterparts. The purpose of this study was to evaluate the current body of available literature regarding S&C in adolescent female athletes, describe potential benefits, and generate recommendations for S&C programs for female adolescent athletes. This systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines...

OBJECTIVES: The purpose of this study was to build on current understanding of Achilles tendon (AT) ruptures in football through the examination of lower extremity injury rates (IR) in the season prior to AT rupture. METHODS: An online review was conducted to document AT ruptures in the National Football League (NFL) from the 2010-11 through 2016-17 seasons. Player-specific information was gathered through the online search, injury reports, or video analysis. Injury incidence was recorded for each season...

BACKGROUND: Rhabdomyolysis is a syndrome characterized by muscle necrosis that leads to release of the intracellular contents of muscle cells into the systemic circulation. Rhabdomyolysis due to overexertion is an uncommon but well-known severe complication of strenuous activity. Exertional rhabdomyolysis (ER) is typically described in weight lifters and military recruits undergoing basic training. Few cases have been reported in football players without known predisposing risk factors...

OBJECTIVE: To investigate the acute effects of high-intensity exercise on blood hepcidin levels and other iron metabolic and hematological parameters in highly trained athletes of dragon boating as a sport performed in a sitting position. METHODS: We conducted an exercise intervention study with a pre- and posttest blood measurement to determine the effects of high-intensity training on hematological and iron metabolic parameters in both male (n = 19) and female (n = 12) elite athletes of the German national dragon boating team...

The use of running applications (RAs) has recently been shown to neither increase nor decrease the risk of running-related injuries (RRIs). However, it is important to note that the study reporting these findings did not account for the influence of virtual competition or challenges, such as virtual leaderboards for certain popular "segments" and monthly "challenges" which reward users for completing predefined tasks in a given time period. Both of these factors may affect the training behaviors of RA users, and indeed may contribute to the risk of RRIs...

OBJECTIVES: Physiological effects of exercise on trained and untrained individuals have been studied extensively. Typically, young or middle-aged individuals are examined before and after short periods of vigorous exertion. METHODS: We studied 6 elderly male athletes (61 ± 8 years (mean ± SD); baseline [Formula: see text]O2 max 48 ± 5 ml·kg-1 ·min-1 ) with focus on cardiac function and biomarkers following 14 consecutive days of moderate intensity exercise...

OBJECTIVES: to identify all studies of Karate injuries and assess injury rates, types, location, and causes. METHODS: Six electronic and four grey literature databases were searched. Two reviewers independently assessed titles/abstracts, abstracted data and assessed risk-of-bias with the Newcastle-Ottawa scale. Average injury rates/1000AE (AE = athletic-encounter) and/1000minutesAE, injury location and type weighted by study size were calculated. RESULTS: In competitions rates of injury/1000AE and/1000 minutesAE were similar for males (111...

OBJECTIVES: The purpose of this investigation was to record head impacts and assess cognitive function throughout a NCAA Division III men's lacrosse season. METHODS: Fifteen NCAA Div III men's lacrosse players (age = 21.1 ± 1.5 years; height = 179 ± 7.00cm; weight = 80.74 ± 8.00kg) wore Smart Impact Monitors (SIM) (Triax Technologies, Inc., Norwalk, CT) within headbands, in 28 practices and 9 home games of one season. The SIM devices communicated with the Triax Technologies SKYi, which confirmed activated SIMs and obtained data of linear acceleration, rotational acceleration, rotational velocity, direction, and location of each head impact...

OBJECTIVE: Polydeoxyribonucleotide as adenosine receptor (A2A ) agonist has been used in plastic surgery and dermatology related to its regenerative property. The aim of this pilot study is to evaluate the safety and efficacy of polydeoxynucleotide injection in patients with rotator cuff tears by a variety of outcomes including pain, disability, physical performance test, and ultrasonography (US). METHODS: Seventeen patients (9 men, 8 women, age: 57.9 ± 9.1) with partial-thickness tear of supraspinatus tendon were evaluated in a prospective, open-label, and pre-and-post study...

Alzheimer's disease (AD) is a debilitating disease influencing a multitude of outcomes, including memory function. Recent work suggests that memory may be influenced by exercise ('memorcise'), even among those with AD. The present narrative review details (1) the underlying mechanisms of AD; (2) whether exercise has a protective effect in preventing AD; (3) the mechanisms through which exercise may help to prevent AD; (4) the mechanisms through which exercise may help attenuate the progression of AD severity among those with existing AD; (5) the effects and mechanisms through which exercise is associated with memory among those with existing AD; and (6) exercise recommendations for those with existing AD...

OBJECTIVE: Both diet and physical activity have been shown to be associated with reduced risk for mortality. The current study examined the individual and combined effects of the inflammatory quality of diet and physical activity levels on mortality risk. METHODS: Data from the 1999-2004 National Health and Nutrition Examination Survey were used (N = 10,610 adults 20-85 years). Participants were followed through 2011, entailing a median follow-up time of 9.6 yrs...

OBJECTIVE: Muscle atrophy is a common side-effect of bed rest during hospitalization. However, resistance training may minimize or even prevent these complications. Therefore, we evaluated the efficiency of four upper-body elastic resistance exercises that could be performed while lying or sitting in a hospital bed. METHODS: Twenty-two healthy subjects performed three repetitions of each exercise in a supine and seated position with a perceived intensity of 3 (low) and 8 (high) on the Borg CR10 Scale...
