Of the few studies examining negative consequences associated with workloads , increases in training load led to increases in injury rates , while longer training duration was associated with a greater incidence of illness .
Conclusion The combined capacity for adolescent males to grow , train and improve physical performance highlights and underscores an exciting responsiveness to training in the football environment .
However , the capacity to train has some established barriers for adolescents experiencing high workloads , which could also result in negative consequences .
Background The expectation that training enhances performance is well explored in professional sport .
However , the additional challenges of physical and cognitive maturation may require careful consideration when determining workloads to enhance performance in adolescents .
Objective The objective of this study was to determine the state of knowledge on the relationship between workloads , physical performance , injury and /or illness in adolescent male football players .
Risk Factors for Injury in Subelite Rugby League Players
Background Although player fatigue and playing intensity have been suggested to contribute to injuries in rugby league players , no study has confirmed if the level of physical fitness is a risk factor for injury in rugby league players . The aim of this study was to identify risk factors for injury in subelite rugby league players . Hypothesis Low physical fitness levels are risk factors for injury in subelite rugby league players . Study Design Cohort study ; Level of evidence , 2 . Methods One hundred fifty-three players from a subelite rugby league club underwent preseason measurements of muscular power ( vertical jump ) , speed ( 10- and 40-m sprint ) , and maximal aerobic power ( multistage fitness test ) over 4 competitive seasons . All injuries sustained by players were prospect ively recorded over the 4 competitive seasons . Results The risk of injury was greater in players with low 10- and 40-m speed . Players with a low maximal aerobic power had a greater risk of sustaining a contact injury . In addition , players who completed less than 18 weeks of training before sustaining their initial injuries were at greater risk of sustaining a subsequent injury . Conclusions Subelite rugby league players with low speed and maximal aerobic power are at an increased risk of injury . In addition , players who complete less than 18 weeks of training before sustaining an initial injury are at greater risk of sustaining a subsequent injury . These findings highlight the importance of speed and endurance training to reduce the incidence of injury in subelite rugby league players
