An assessment of training volume in professional rugby union and its impact on the incidence, severity, and nature of match and training injuries
Abstract A prospect i ve cohort study was used to assess the influence of training volume on injuries sustained by 502 professional rugby union players in Engl and . Training volumes ( excluding warm-ups , cool-downs , and recovery sessions ) , player injuries , and player match exposure times were reported weekly . Higher training volumes ( > 9.1 hours per week ) did not increase the incidence of match or training injuries . However , higher training volumes did increase the severity of match injuries , particularly during the second half , and consequently result ed in a significant increase in the number of days ' absence due to match injuries . Although lower-limb injuries were the most common match and training injuries , shoulder dislocations/instabilities result ed in more days ' absence during weeks of higher training volumes , but the differences were not significant . The least number of days lost due to injuries occurred during weeks of intermediate training volumes ( 6.2–9.1 h per week ) . Training volume was not correlated with final league position . Fitness testing , defence , and rucking and mauling components were identified as being very high- or high-risk training activities . Our results provide evidence of the benefits of modifying the volume and content of rugby union training to reduce the risk associated with injuries to professional players
