Purpose:To explore the association between in-season training-load (TL) measures and injury risk in professional rugby union players.Methods:This was a 1-season prospective cohort study of 173 professional rugby union players from 4 English Premiership teams. TL (duration × session-RPE) and time-loss injuries were recorded for all players for all pitch- and gym-based sessions. Generalized estimating equations were used to model the association between in-season TL measures and injury in the subsequent week.Results:Injury risk increased linearly with 1-wk loads and week-to-week changes in loads, with a 2-SD increase in these variables (1245 AU and 1069 AU, respectively) associated with odds ratios of 1.68 (95% CI 1.05–2.68) and 1.58 (95% CI 0.98–2.54). When compared with the reference group (<3684 AU), a significant nonlinear effect was evident for 4-wk cumulative loads, with a likely beneficial reduction in injury risk associated with intermediate loads of 5932–8651 AU (OR 0.55, ...

Background and objectives: The incidence of injuries in rugby is extremely high, but studies have rarely examined the predictors of injury in amateur players. This study aimed to systematically analyse sports and injury factors as potential predictors of musculoskeletal injuries in senior-level amateur rugby players. Methods: The participants in this study were 101 senior-level rugby players from Croatia (average of 24.64 years old). At baseline, all participants were tested on sociodemographic and anthropometric parameters (age, body height and mass), consumption of dietary supplements, preseason injury status and training volume, and sport factors (position in game). Data on injury occurrence (dependent variable), prevalence of pain, training status, and characteristics of the played match were surveyed prospectively once a week during the three-month period (one half-season). Results: The logistic regression revealed a higher injury occurrence in forward players of the 1st row, 2...

BACKGROUND There are sparse scientific data concerning the aetiology and incidence of injuries in the Super 12 rugby competition. Aim. The aim of the study was to document the incidence, nature and risk factors associated with injuries during a Super 12 rugby competition. METHODS Injuries, defined as injuries preventing playing or training, or requiring medical treatment, were recorded in a cohort of 75 South African Super 12 players over one season. Injury severity was graded according to sessions missed: minor (1 - 3 missed), intermediate (4 - 9) and severe (> 9). RESULTS During the tournament, a total of 740 player game hours and 4 900 player training hours were recorded. The overall incidence of injuries was 55.4 injuries/1,000 player game hours, and 4.3 injuries/1,000 player training hours. The most common injury types were: ligament sprains (25.8%), musculotendinous strains/tears (24.2%). The most common injured sites were: pelvis, hip (19.3%), head and knee (12.9% each). T...

To determine the incidence and nature of injuries in the Super Rugby tournament over a 5-year period. 482 male professional rugby union players from six South African teams participating in the Super Rugby tournament were studied (1020 player-seasons). Medical staff of participating teams (2012-2016 tournaments) recorded all time loss injuries (total injuries and match injuries) and exposure hours (93 641 total playing hours; 8032 match hours). Injury incidence, injured player proportion, severity (time lost), anatomical location, tissue type and activity/phase during which injury occurred are reported. The overall incidence of match injuries (per 1000 player-hours; 95% CI) for each year was as follows: 2012 (83.3; 69.4-99.2); 2013 (115.1; 98.7-133.5); 2014 (95.9; 80.8-113.1), 2015 (112.3; 96.6-129.9) and 2016 (93.2; 79.9-107.9). The injured player proportion for each year was as follows: 2012 (54.6%); 2013 (49.4%); 2014 (52.0%); 2015 (50.0%); and 2016 (39.8%). The thigh, knee, head...

Musyarakah Mutanaqisah is generally an agreement between two or more parties on the basis of their participation in known capital, provided that the return between them is according to the agreement and the loss according to the capital with the commitment of one of them to transfer its share to the other party, under special conditions of contracts, which is a contract consisting of several contracts linked to each other in more The images, and that the nature of this contract is based on an overlap between a group of contracts that take each other's necks, and complex contracts have effects, so that all other obligations of those contracts combined or opposite, and all the rights and obligations arising from them in one sentence that does not accept separation and fragmentation, are the effects of a single contract, Building On this problem, this research aims to analyze the forms of installation in financial contracts, and to investigate the most likely jurisprudential interp...
