A contribution to a special issue on Hormones and Human Competition. Since Archer's (2006) influential meta-analysis, there has been a major increase in the number of studies investigating the effect of competition outcome on testosterone reactivity patterns in humans. Despite this increased research output, there remains debate as to whether competition outcome modulates testosterone concentrations. The present paper examines this question using a meta-analytic approach including papers published over the last 35years...

There have been many advances in the management of neck pain disorders, but a personal frustration as a clinician and researcher in the field is that the incidence of full recovery following a whiplash injury as a result of a motor vehicle crash has not increased and, subsequently, the rate of transition to chronic neck pain has not lessened. The commentaries in this special issue reflect the multifaceted nature of whiplash-associated disorders and the wide-ranging research in the field. While management of whiplash, especially the challenge of lessening the rate of transition to chronicity, has yet to be achieved, the picture is becoming clearer...

BACKGROUND: There has been increased emphasis in orthopaedics on high-quality prospective research to provide evidence-based treatment guidelines, particularly in sports medicine/shoulder surgery. The external validity of these studies has not been established, and the generalizability of the results to clinical practice in the United States is unknown. HYPOTHESIS: Comparison of patient demographics in major prospective studies of arthroscopic sports and shoulder surgeries to patients undergoing the same procedures in the National Surgical Quality Improvement Program (NSQIP) database will show substantial differences to question the generalizability and external validity of those studies...

Dramatic increases in youth competitive athletic activity, early sport specialization, and year-round training and competition, along with increased awareness of anterior cruciate ligament (ACL) injuries in children, have led to a commensurate increase in the frequency of ACL tears in the skeletally immature. Recent understanding of the risks of nonoperative treatment and surgical delay have supported a trend toward early operative treatment. This article discusses treatment strategies for ACL injuries in children and adolescents, and offers our preferred treatment strategy for skeletally immature youth athletes with ACL tears...

We developed and validated an aquaticity assessment test (AAT) for the evaluation of human physical adequacy in the water. Forty-six volunteers (25M/21F; 20 ± 8 years) participated and performed 10 easy-to-administer and practical aquatic tasks. Group A was formed by 36 elite athletes (M/F 20/16, 24.7 ± 10yrs) from two sports categories depending on their affinity to the water environment: terrestrial (wrestling, cycling, dancing) and aquatic (swimming, synchronized swimming, free diving) sports. Group B was formed by 10 non-athlete participants (5M/5F, 14...
