INTRODUCTION: Protein (PRO) combined with a carbohydrate (CHO) beverage may have an ergogenic effect on endurance performance. However, evidence regarding its efficacy on similar conditions to athletes' race day is still lacking. OBJECTIVE: To compare the effect of three different nutritional supplementation strategies on performance and muscle recovery in a duathlon protocol. METHODS: , 13 male athletes (29.7 ± 7.7 years) participated in three simulated Olympic-distance duathlons under three different, randomly assigned, supplementation regimens: carbohydrate drink (CHO, 75 g); isocaloric CHO plus protein drink (CHO+PRO, 60...

OBJECTIVES: Young athletes' participation in competitive sports is becoming increasingly common, and this increased involvement raises concerns about the occurrence of overtraining and sports injuries. Since these issues are poorly understood, this study analyzed heart rate variability, stress/recovery relationship, and sports injury incidence during a training macrocycle of young sprint and endurance swimmers. METHODS: Thirty teenage swimmers (aged 12 to 17 years) were divided into two groups as follows: Sprint (n=17) and Endurance (n=13)...

The all-inside technique (AIT) for anterior cruciate ligament reconstruction (ACLR) is gaining popularity as a more anatomic, less invasive, technique with the potential for more rapid recovery. This systematic review aims to critically assess components of the technique, its safety profile, outcomes, and complications. PUBMED, EMBASE, and MEDLINE were searched for studies discussing primary ACLR using the AIT. Article screening, quality assessment, and data abstraction were completed in duplicate, and a minimal clinically important difference (MCID) was used to frame the descriptive results in a clinically significant context...

The vertical treadmill (VertiRun) is an unresearched mode of exercise where users engage in a "running-like" action whilst body weight is supported by a recumbent bench and overhanging resistance cables are tethered to the user's ankles. The purpose of this study was to determine the effects of training on a VertiRun and any cross-training effect on running performance. Thirty active males (age, 22±4 years; stature, 1.79±0.08 m; body mass, 78.5±12.6 kg) volunteered for this study. Participants' aerobic and anaerobic running performance were determined by incremental maximum rate of oxygen consumption (VO2max) treadmill test and a maximum anaerobic running test (MART), respectively...

CONTEXT:   Return-to-sport criteria after anterior cruciate ligament (ACL) injury are often based on "satisfactory" functional and patient-reported outcomes. However, an individual's decision to return to sport is likely multifactorial; psychological and physical readiness to return may not be synonymous. OBJECTIVE:   To determine the psychosocial factors that influence the decision to return to sport in athletes 1 year post-ACL reconstruction (ACLR)...

In contrast to anterior cruciate ligament reconstruction, there is a paucity of primary studies that address the issue of return to play after anterior shoulder stabilization for glenohumeral instability. Most studies focused on clinical outcomes after anterior shoulder stabilization provide little detail on the authors' assessment protocols used in determining return to sport readiness. In fact, many issues germane to the postoperative rehabilitation process (biologic healing, motion recovery, strength recovery, and sport-specific considerations) remain poorly defined, and are not typically addressed using validated shoulder outcomes instruments...

Prior studies suggest that concussion may lead to an increased risk of a subsequent time-loss sport-related injury, but the mechanisms responsible are unknown. We measured the symptom and dual-task gait outcomes for athletes initially post-concussion and after clinical recovery. Participants then self-reported any additional injuries incurred in the year after their concussion. Forty-two athletes (52% female, mean age=16.8±3.2 years) completed the study. They underwent a dual-task gait evaluation and symptom inventory within 21 days post-concussion, and again after they were deemed clinically recovered...

Many patients are afflicted with painful conditions affecting both hips, most commonly femoroacetabular impingement. Some patients prefer the advantage of undergoing a single surgical procedure and anesthetic followed by a single postoperative rehabilitation program. We present a Technical Note on single-stage bilateral hip arthroscopy. This Technical Note reports on key steps enabling safe and efficient performance of bilateral arthroscopic acetabuloplasty, labral refixation, femoroplasty, and dynamic testing while limiting traction times and facilitating rapid transition to the second hip arthroscopic surgery...

BACKGROUND: Single leg squats are commonly used subjective assessments of general biomechanical function, injury risk, as a predictor for recovery and as an outcome measure of rehabilitation. While 3D motion capture is a useful tool for elite sports performance and research it is impractical for routine clinical use. RESEARCH QUESTION: This cross-sectional study aims to: assess reliability and validity of clinicians' subjective ratings of single leg squats compared to 3D motion capture, and to identify whether performance predicts joint moments...

BACKGROUND: Fear avoidance can play a prominent role in maladaptive responses to an injury. In injured athletes, such pain-related fear or fear avoidance behavior may have a substantial influence on the recovery process. Specifically, it may explain why some are able to reach their preinjury abilities, whereas others are unable to return to sport. QUESTIONS/PURPOSES: (1) Is fear avoidance in athletes associated with decreased physical function after injury? (2) To what degree is fear avoidance associated with athletes' pain intensity? METHODS: In a cross-sectional study, we recruited injured athletes-defined as patients with sports-related injury, weekly engagement in sport activities, participation in competitive events as part of a team or club, self-identification as an athlete, and a desire to return to sport after recovery-from an orthopaedic sports medicine center at a major urban university hospital...

The controversy about surgical vs conservative treatment of the injured spine with cord damage is centuries old. Until the end of the Second World War the majority of patients died or lived a short miserable life. Subsequently, Guttmann, an experienced neurosurgeon, realised surgery was not beneficial and sometimes detrimental to the person with spinal cord injury. Guttman, Frankel and others demonstrated with expert conservative management of the spine and the multi-system consequences of cord damage most patients made some neurological recovery and most with incomplete cord injury recovered ambulation regardless of X-ray findings...

The loss of players through injury is known to affect team performance in many sports; it is important therefore for professional teams to be able to quantify the likely injury-burden that will be encountered throughout a season. A kinetic model, based on the rates at which match and training injuries are sustained and resolved, a team's squad size and the 2017/18 season fixture schedule for teams competing in the English Premier League, is used to produce daily forecasts of injury-burden experienced by a typical team...

Block periodization (BP) has been proposed as an alternative approach for application in the context of high-level sports. Despite its growing acceptance, there is no empirical evidence of BP adoption in high-level judo athletes. Therefore, this study aimed to compare the maximal strength, muscle power, judo-specific performances, and hormonal concentration changes of state/national level (NG) and international level (IG) judo athletes subjected to BP. Twenty-one elite judo athletes (international level = 10; 21...

Historically, heat has been used in various clinical and sports rehabilitation settings to treat soft tissue injuries. More recently, interest has emerged in using heat to pre-condition muscle against injury. The aim of this narrative review was to collate information on different types of heat therapy, explain the physiological rationale for heat therapy, and to summarise and evaluate the effects of heat therapy before, during and after muscle injury, immobilisation and strength training. Studies on skeletal muscle cells demonstrate that heat attenuates cellular damage and protein degradation (following in vitro challenges/insults to the cells)...
