Roberts et al. – Epidemiology of knee injuries in English community rugby union

PDF Roberts_eposter_rsnlive16 – click to view AIM To establish the incidence and nature of knee time-loss injuries in English community rugby and to assess differences between different levels of play and between playing positions. METHODS Over 6 rugby seasons (2009-10 to 2014-15), medical staff from English community rugby union clubs reported information for match play knee injuries resulting in eight days or greater absence. RESULTS There was an overall incidence of 2.7 knee injuries per 1000 player match hours with an average severity of 10.7 weeks absence. There was no difference between semi-professional (3.1 95% CI 2.6-3.7), amateur (2.6 95% … Continue reading Roberts et al. – Epidemiology of knee injuries in English community rugby union

Burns et al. – Machine scrummaging does not mimic the head/neck load experienced in live scrummaging

PDF Burns_eposter_rsnlive16 – click to view AIM To determine and compare the force exerted upon the head and relative position of the cervical spine during the sustained push phase of scrummaging across the front row (FR), under both machine and … Continue reading Burns et al. – Machine scrummaging does not mimic the head/neck load experienced in live scrummaging

Morel et al. – The force-velocity characteristic of the contraction influences the mechanisms of central motor drive inhibition – implication for Rugby

PDF Morel_eposter_rsnlive16 – click to view AIM During high intensity exercise, metabosensitive muscle afferents are thought to inhibit the command motor drive. However, this paradigm cannot explain the high motor drive inhibition despite low metabolic stress observed during high force … Continue reading Morel et al. – The force-velocity characteristic of the contraction influences the mechanisms of central motor drive inhibition – implication for Rugby

Pinfold et al. – Descriptive Analysis of Linear and Angular Acceleration Forces Experienced at the Head During a Simulated Front-on Rugby Union Tackle

PDF Pinfold_eposter_rsnlive16 – click to view AIM To explore the head acceleration profile of forwards and backs during a simulated front-on rugby tackle METHODS Forty-one rugby union players each performed 10 tackles (5 left and 5 right) against a 50kg bag traveling at a speed of 4.2m/s. Formalized instructions were provided to standardize the procedure and technique. During each tackle a CSx Head Positioning Unit was worn behind the ear. The sensor recorded linear (4000Hz) and angular head acceleration (3200Hz) over a 15ms period for all impacts exceeding a 10g threshold. RESULTS Peak linear and rotational acceleration values of 88±51g … Continue reading Pinfold et al. – Descriptive Analysis of Linear and Angular Acceleration Forces Experienced at the Head During a Simulated Front-on Rugby Union Tackle

Furlan – Perceptual effects of a congested day of simulated Rugby Sevens

PDF Furlan_eposter_rsnlive16 – click to view AIM In attempt to assess the effects of a new Rugby Sevens simulation protocol (R7SP), the aim of this study was to investigate the perceptual responses to a simulated day of Rugby Sevens. METHODS Ten male representative-level rugby players (stature 184 ± 6 m, body mass 86 ± 8 kg, age 22 ± 4 y) performed three R7SP interspersed by a 2 h period. Participants’ subjective ratings of ‘readiness for exercise’, ‘fatigue’ and ‘muscular pain’ were assessed using a 10-cm visual-analog scale at arrival (PRE) and 1 h following the last R7SP (POST). RESULTS … Continue reading Furlan – Perceptual effects of a congested day of simulated Rugby Sevens

Seminati et al. – Neuromuscular activation strategies during different rugby tackling conditions

PDF Seminati_eposter_RSNlive16 – click to view AIM To investigate neuromuscular activation strategies during simulated Rugby Union tackles, which are known to be a common injury event. METHODS A 50 kg punch bag translated towards the tackler through a pulley system … Continue reading Seminati et al. – Neuromuscular activation strategies during different rugby tackling conditions

Salmon et al. – A baseline profile of brain health in a semi-professional Rugby Union team

PDF Salmon_eposter_RSNLive16 – click to view AIM To observe brain health at pre-season in a semi-professional rugby team. METHODS 55 semi-professional players provided data during a pre-season screen using the following measures: Pittsburgh Sleep Quality Index (PSQI), Rivermead Post Concussion Symptom Questionnaire (Rpq-3 and Rpq-13) Beck Depression Inventory (BDI-II) and Beck Anxiety Inventory (BAI) and the University of Pennsylvania Smell Identification Test. RESULTS A disturbed sleep pattern and sense of smell were noted in 41.8% and 55.8% of players. BDI-II indicated that 72.7% were minimally and 5.5% were mildly depressed. The BAI revealed that 50.9% had minimal, 18.2% mild and … Continue reading Salmon et al. – A baseline profile of brain health in a semi-professional Rugby Union team

Robinson & Twist – Neuromuscular, physiological and perceptual responses to linear vs. multidirectional high intensity running sessions in academy rugby union players

PDF Robinson_eposter_RSNLive16 – click to view AIM To investigate the neuromuscular, physiological and perceptual responses to two types of modified high-intensity running sessions typically used in rugby training environments. METHODS Twenty-five male academy rugby union players performed two separate shuttle running protocols eight days apart. Participants completed 50 x 30 m shuttles, alternating maximal running and walking (total 3000 m), for: i) linear acceleration (SL) and ii) multidirectional change of direction with acceleration and deceleration (CoD). Measures of muscle function (i.e. knee flexion, knee extension, shallow range eccentric hamstring and thigh adductor squeeze) were recorded before and immediately after performing … Continue reading Robinson & Twist – Neuromuscular, physiological and perceptual responses to linear vs. multidirectional high intensity running sessions in academy rugby union players
