Overhead throwing is a common causative factor in disorders of the proximal biceps in athletes. In recent years, arthroscopic repair of unstable superior labral tears or biceps tendonitis involving the long head of the biceps tendon anchor has become the standard of care. However, in some cases, superior labrum anterior-posterior (SLAP) repair requires additional evaluation and even revision surgery, which contributes to patient dissatisfaction. Differentiating overall biceps tendonitis from superior labral tears alone can be a challenge...

As the field of hip arthroscopy continues to grow rapidly, our understanding of the population of patients undergoing hip arthroscopy has led to improved diagnosis and management of hip joint pathologies. The Multicenter Arthroscopic Study of the Hip (MASH) Study Group conducts multicenter clinical studies in arthroscopic hip preservation surgery. Patients undergoing arthroscopic hip preservation surgery are enrolled in a large prospective longitudinal cohort at 10 separate sites nationwide by 10 fellowship-trained hip arthroscopists...

PURPOSE OF REVIEW: During the last decades androgens have been used illicitly by athletes of both genders. Because of some obvious ethical limitations, mechanisms underlying the performance-enhancing effects of these hormone or drugs, as well as the magnitude of their effects, have been poorly addressed. This review aims to combine findings from field and from the laboratory to provide new insights into the ergogenic properties of endogenous or exogenous androgens on female athletes. RECENT FINDINGS: Results obtained from recent neuropsychological studies indicated that testosterone, and not the sex chromosomes, is responsible for the sexual differentiation of visuospatial neural activation...

BACKGROUND: Although studies have shown increased rates of chondral injury with delayed surgical treatment of pediatric anterior cruciate ligament (ACL) injuries, it is unknown if this is related to a delay in diagnosis and appropriate activity restrictions. The purpose of this study was to determine if the time from injury to diagnosis, time from diagnosis to reconstruction, and preoperative activity level correlate with the degree of cartilage injury seen intraoperatively. METHODS: A retrospective review of skeletally immature patients who underwent ACL reconstruction was performed...

Accurate assessment of body composition is an important consideration for athletes as it is a health/performance variable. However, little is known about the variability in values obtained across different assessment methods for specific athlete populations. The purpose of this study was to compare two common laboratory methods that assess body composition: air displacement plethysmography (BOD POD™) and dual energy x-ray absorptiometry (DXA). Twenty-nine male collegiate hockey players, (Age = 24.07 ± 1...

The highest exercise intensity that can be maintained at the end of a ramp or step incremental test (i.e., velocity or work rate at VO2max - Vpeak/Wpeak) can be used for endurance performance prediction and individualization of aerobic training. The inter-individual variability in Vpeak/Wpeak has been attributed to exercise economy, anaerobic capacity and neuromuscular capability, alongside the major determinant of aerobic capacity. Interestingly, findings following concurrent strength and endurance training performed by endurance athletes have challenged the actual contribution of these variables...

Musculoskeletal injuries (MSK-I) are a significant health problem for both military and athletic populations. Research indicates MSK-I is associated with physical fitness; however, the association between specific components of physical fitness and MSK-I in military and athletic populations has not been systematically examined. Our goal was to systematically review the literature to provide a best evidence synthesis on the relationship between components of physical fitness and MSK-I risk in military and civilian athletic populations...

Ammonia inhalant (AI) use by powerlifters and weightlifters is a prevalent practice with little research support for improved performance. The purpose of this study was to investigate the effects of ammonia as a stimulant on athletic performance during a dead lift one maximal repetition (1-RM) absolute strength test. Subjects (n=10 men, mean±SD age=21±1 years, mass=72.5±6.8 kg; n=10 women, age=22±5 years, mass=66.2±8.1 kg) were required to have at least two years of resistance training experience while lacking a history of asthma, lightheadedness, fainting, anaphylaxis, sickle cell traits, and other respiratory disorders...

OBJECTIVES: The Functional Movement Screen (FMS) is a popular screening tool, however, the postulated relationship between prospective injury and FMS scoring remains sparsely explored in adolescent athletes. The aim of the study was to examine the association between pre-season FMS scores and injuries sustained during one regular season competition in elite adolescent Australian football players. DESIGN: Prospective cohort study. METHODS: 237 elite junior Australian football players completed FMS testing during the late pre-season phase and had their weekly playing status monitored during the regular season...

For the past few years, children affected by an inherited channelopathy have been counseled to avoid (recreational) sports activities and all competitive sports so as to prevent exercise-induced arrhythmia and sudden cardiac death. An increased understanding of the pathophysiological mechanisms, better anti-arrhythmic strategies, and, in particular, more epidemiological data on exercise-induced arrhythmia in active athletes with channelopathies have changed the universal recommendation of "no sports," leading to revised, less strict, and more differentiated guidelines (published by the American Heart Association/American College of Cardiology in 2015)...

When active muscles are stretched, our understanding of muscle function is stretched as well. Our understanding of the molecular mechanisms of concentric contraction has advanced considerably since the advent of the sliding filament theory, whereas mechanisms for increased force production during eccentric contraction are only now becoming clearer. Eccentric contractions play an important role in everyday human movements, including mobility, stability, and muscle strength. Shortly after the sliding filament theory of muscle contraction was introduced, there was a reluctant recognition that muscle behaved as if it contained an "elastic" filament...

Sudden cardiac death (SCD) is the leading cause of mortality in athletes during sport. A variety of mostly hereditary, structural, or electrical cardiac disorders are associated with SCD in young athletes, the majority of which can be identified or suggested by abnormalities on a resting 12-lead electrocardiogram (ECG). Whether used for diagnostic or screening purposes, physicians responsible for the cardiovascular care of athletes should be knowledgeable and competent in ECG interpretation in athletes. However, in most countries a shortage of physician expertise limits wider application of the ECG in the care of the athlete...

Many Olympians and Paralympians would not be called athletes if what dictates this classification is fulfilling the criteria of Araujo and Scharhag (2016). Shelley Watts, Australian amateur boxer and Commonwealth gold medallist undertakes a double degree in law and sports science, something which undoubtedly takes up a considerable number of hours throughout her week (Australian Olympic Committie [AOC], 2016). There are many other athletes in similar positions - College athletes in the United States who are part of the National Collegiate Athletic Association (NCAA), for example...

Clinical and laboratory identification of the underlying risk of respiratory illness in athletes has proved problematic. The aim of this study was to determine whether clinical data, combined with immune responses to standardised exercise protocols and genetic cytokine polymorphism status, could identify the risk of respiratory illness (symptoms) in a cohort of highly-trained athletes. Male endurance athletes (n=16; VO2max 66.5 ± 5.1 underwent a clinical evaluation of known risk factors by a physician and comprehensive laboratory analysis of immune responses both at rest and after two cycling ergometer tests: 60 min at 65% VO2max (LONG); and 6 x 3 min intervals at 90% VO2max (INTENSE)...

BACKGROUND: Parameters related to the anaerobic capacity and power may be important for the performance of many sports whose skills are related to high-intensity and short- duration efforts. Although plyometric training (PT) has been widely used in the regular strength and conditioning programs of young athletes, its effects on anaerobic performance are still controversial. Therefore, the purpose of the present study was to evaluate the effects of PT in anaerobic performance in young athletes...
