Targeted resistance training stimulates hamstring muscle hypertrophy, but its effect on tendon‐aponeurosis geometry is unknown. This study examined changes in hamstring muscle, free tendon, and aponeurosis geometry following a 10 week Nordic or hip extension exercise intervention. Thirty recreationally active males were randomly allocated (n = 10 p...

Objectives Hamstring strain injuries (HSIs) commonly affect the proximal biceps femoris long head (BFlh) musculotendinous junction. Biomechanical modeling suggests narrow proximal BFlh aponeuroses and large muscle‐to‐aponeurosis width ratios increase localized tissue strains and presumably risk of HSI. This study aimed to determine if BFlh muscle a...

Introduction Recently, there has been a call for vertical jump testing via force-plate analysis to be included in the assessment of individuals following anterior cruciate ligament reconstruction (ACLR) and as part of return to play criteria. However, a synthesis of current literature is needed to help guide clinicians on what tests to perform, whi...

Context: Hamstring strain injuries (HSIs) are the most frequently sustained injury in Major League Baseball (MLB). However, the beliefs and practices of MLB practitioners regarding HSI risk factors and prevention strategies in baseball athletes, have not been documented. Objective: To document the current beliefs and practices of MLB practitione...

Background Exposure to increased mechanical loading during physical training can lead to increased tendon stiffness. However, the loading regimen that maximises tendon adaptation and the extent to which adaptation is driven by changes in tendon material properties or tendon geometry is not fully understood. Objective To determine (1) the effect of...

The countermovement jump (CMJ) is used to profile and monitor lower body neuromuscular performance in a variety of sports. While jump height, peak power and peak force are commonly reported CMJ variables (CMJ-TYP), several temporal and rate-limited kinetic "alternative" (CMJ-ALT) variables have shown greater response to acute and chronic load, but...

Objective: The aim of this review was to investigate if exercise induced hypoalgesia (EIH) occurs following isometric muscle contraction in people with local musculoskeletal symptoms. Design: Systematic review. Data sources: MEDLINE, EMBASE, CINAHL & SportDiscus electronic databases were searched (inception to April 2020). Eligibility criteri...

Purpose Whilst kicking in Rugby Union can be influential to match outcome, the epidemiology of kicking injuries remains unknown. This study therefore aimed to investigate the epidemiology of injuries attributed to kicking in professional rugby, including playing position‐specific effects and differences in kicking volumes and kick types. Methods F...

Epidemiological studies in the performing arts are scarce, and only one such study in the last 20 years directly examines West End productions. Therefore, the aim of this study was to analyse the epidemiology of injuries sustained by West End performers over a 12-month period (2016-2017). Injury data were self-reported retrospectively by West End p...

Mixed marital arts (MMA) is a hybrid of a number of fighting styles. Time motion analysis demonstrates that the high and low intensity work ratio of 1:4 appears to be similar to other martial arts such as taekwondo and kick boxing. The intermittent nature of such repeated high intensity work periods suggests that energy is produced by predominantly...
