Offensive Sequences in Youth Soccer: Effects of Experience and Small-Sided Games

The present study aimed to analyze the interaction and main effects of deliberate practice experience and smallsided game format (3 vs. 3 and 6 vs. 6 plus goalkeepers) on the offensive performance of young soccer players. Twentyeight U-15 male players were divided into 2 groups according to their deliberate practice experience in soccer (i.e., years of experience in federation soccer): Non-Experienced (age: 12.84 ± 0.63 years) and Experienced (age: 12.91 ± 0.59 years; experience: 3.93 ± 1.00 years). The experimental protocol consisted of 3 independent sessions separated by one-week intervals. In each session both groups performed each small-sided game during 10 minutes interspersed with 5 minutes of passive recovery. To characterize the recorded offensive sequences we used the Offensive Sequences Characterization System, which includes performance indicators previous applied in other studies. No interaction effects on the offensive performance were found between both factors. Non-parametric MANOVA revealed that the factor “experience level” had a significant effect (p<0.05) on performance indicators that characterize the development of offensive sequences, especially in 6 vs. 6 + GKs. While experienced players produced longer offensive sequences with greater ball circulation between them, the non-experienced participants performed faster offensive sequences with a predominance of individual actions. Furthermore, significant differences were observed (p<0.05) in the development and finalization of offensive sequences within each group, when comparing small-sided game formats. Evidence supports that small-sided games can serve several purposes as specific means of training. However, the manipulation of game format should always consider the players’ individual constraints.

Combined Small‐Sided Game and High‐Intensity Interval Training in Soccer Players: The Effect of Exercise Order

Abstract

The aim of the present study was to compare combined small‐sided game (SSG) and high‐intensity interval training (HIT) with different order. Twenty‐one semi‐professional soccer players were divided into two groups: SSG+HIT (n = 10) and HIT+SSG (n = 11), and underwent similar four‐week training programs. Players completed the 30‐15 Intermittent Fitness Test (30‐15IFT) before and after the experiment; maximum speed (VIFT) was recorded. During the experiment, seven sessions of SSG (3 vs 3) and HIT (15ʺ‐15ʺ with 95‐100% VIFT) were implemented. Weekly accumulated training loads for both groups during the experiment were similar. Moderate improvements in VIFT were observed in both SSG+HIT (+6.2%, 90% confidence limits, [CL] 4.6; 7.7 and Effect Size, [ES] +0.96) and HIT+SSG (+6.9%, 90% CL 4.6; 9.3 and ES +0.97) groups. Between‐group difference in changes of VIFT was trivial (+0.7%, 90% CL ‐1.8; 3.3 and ES +0.11). Combining SSG and HIT in different order elicited the same enhancement in high‐intensity intermittent performance in soccer players.

Player Load and Metabolic Power Dynamics as Load Quantifiers in Soccer

). Furthermore, FIFA (International Federation of Association Football) has recently approved the use of electronic devices in official competitions (Laws of the Game 2015‐2016). More recently, the development of inertial devices has enabled internal and external training loads to be monitored with the same unit. These devices are composed of different sensors (accelerometer, gyroscope, magnetometer, GPS, etc.) and they have attained excellent validity and reliability ( Barrett et al., 2016 ; Coutts and Duffield, 2010 ). Nowadays, one of the most frequently used load
