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 .
Generic versus small-sided game training in soccer.
The aim of this study was to compare 7 weeks of soccer-specific small-sided game ( SSG ) and mixed generic fitness training , on selected physiological , perceptual and performance variables .  Twenty-five elite youth players were r and omly allocated to either a SSG ( coach selected ) or generic training group ( GTG ) , in a r and omised , parallel matched-group design . In addition to normal training , each group completed two fitness training sessions per week of equal duration . Players completed a V O ( 2 max ) treadmill test , Multistage Fitness Test ( MSFT ) , Yo-Yo Intermittent Recovery Test Level 1 ( YYIRTL1 ) , 12x20 m test of repeated-sprint ability ( RSA ) and 20-m sprint test pre and post training . Training heart rate , perceived training intensity and perceptual fatigue measures were recorded throughout the training period . There were no differences in training heart rate or perceptual well-being measures . However , the GTG did perceive their training to be more intense than SSG . There were no changes in either group for V O ( 2 max ) , MSFT , RSA or sprint performance . However , there were improvements in YYIRTL1 performance for both groups over time , but not between groups . The results show that both types of training are equally effective at improving pre-season YYIRTL1 performance , despite GTG being perceived to be more intense
