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 .
Physiological and performance effects of generic versus specific aerobic training in soccer players.
The aim of this study was to compare the effects of specific ( small-sided games ) vs. generic ( running ) aerobic interval training on physical fitness and objective measures of match performance in soccer . Forty junior players were r and omly assigned to either generic ( n=20 ) or specific ( n=20 ) interval training consisting of 4 bouts of 4 min at 90 - 95 % of maximum heart rate with 3 min active rest periods , completed twice a week . The following outcomes were measured at baseline ( Pre ) , after 4 weeks of pre-season training ( Mid ) , and after a further 8 weeks of training during the regular season ( Post ) : maximum oxygen uptake , lactate threshold ( Tlac ) , running economy at Tlac , a soccer-specific endurance test ( Ekblom 's circuit ) , and indices of physical performance during soccer matches ( total distance and time spent st and ing , walking , and at low- and high-intensity running speed ) . Training load , as quantified by heart rate and rating of perceived exertion , was recorded during all training sessions and was similar between groups . There were significant improvements in aerobic fitness and match performance in both groups of soccer players , especially in response to the first 4 weeks of pre-season training . However , no significant differences between specific and generic aerobic interval training were found in any of the measured variables including soccer specific tests . The results of this study showed that both small-sided games and running are equally effective modes of aerobic interval training in junior soccer players
