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 .
Changes in perceived stress and recovery in overreached young elite soccer players.
The aim of this study was to prospect ively monitor sport-specific performance and assess the stress-recovery balance in overreached ( OR ) soccer players and controls . During two competitive seasons , 94 players participated in the study . The  stress-recovery balance ( RESTQ-Sport ) and sport-specific performance ( Interval Shuttle Run Test )  were assessed monthly . Seven players with performance decrement of at least a month were classified as OR .  Stress and recovery measures were assessed between groups ( OR vs healthy players ) and at different times within the OR group . An unfavorable total recovery score appeared 2 months before diagnosis when compared with the reference values of the healthy group established at the start of the season ( P=0.009 ) and also over the two seasons ( P=0.028 ) . The scales Emotional Stress ( P=0.044 ) , Physical Recovery ( P=0.009 ) , General Well-being ( P=0.001 ) and Sleep Quality ( P=0.045 ) were sensitive to OR compared with the average of the healthy group over the two seasons . Finally , Fatigue and Being in Shape demonstrated the largest changes in stress and recovery within the OR players ( effect size=1.14 and 1.50 ) . The longitudinal monitoring of performance and changes in stress and recovery may be useful for the detection of OR in its earliest stage . The information obtained from these tests can be used to optimize individual training and recovery programs
