Effects of Small-Sided Games and Repeated Sprint Training in Young Soccer Players

2026년 9월 4일 업데이트: Muhammed Zahit Kahraman, Bitlis Eren University

Effects of Small-Sided Games and Repeated Sprint Training on Body Composition, Anaerobic Power, and Selected Biomotor Characteristics in Young Male Soccer Players

The purpose of this study is to compare the effects of 6-week Small-Sided Games (SSG) and Repeated Sprint Training (RST) on body composition, anaerobic power, and selected physical performance qualities in young male soccer players. A total of 24 active male soccer players (aged 16 to 20 years) participating in the Regional Amateur League were randomly assigned into three equal groups: Small-Sided Games Group (SSGG) completing a 4 vs. 4 transition possession game 3 days a week in addition to routine training, Repeated Sprint Training Group (RSTG) completing a 20-meter maximal repeated sprint protocol 3 days a week in addition to routine training, and Control Group (CG) continuing only their routine soccer practice schedule. Before and after the 6-week intervention, participants underwent laboratory and field testing to evaluate body composition (body fat percentage, fat-free mass, BMI), acceleration and maximal speed (10m and 20m sprint tests), agility (Illinois Agility Test), explosive lower-body power (countermovement jump), and maximal anaerobic power (30-second Wingate test) to determine which specific training method provides superior athletic adaptations.

상세 설명

High-intensity intermittent actions, such as accelerations, change-of-direction movements, jumps, and repeated sprints, are critical determinants of competitive performance in soccer. To optimize these physical attributes, coaches commonly utilize Small-Sided Games (SSG) and Repeated Sprint Training (RST). However, comparative evidence regarding the specific adaptations induced by these two distinct conditioning strategies alongside regular soccer practice remains crucial for athletic periodization.

This 6-week randomized controlled trial evaluated 24 young male soccer players randomly allocated into three parallel arms (n=8 per group): SSGG, RSTG, and a Control Group (CG).

Training Protocols:

  • SSGG Protocol: Performed a "4 vs. 4 Transition Possession" format on two adjacent zones 3 days per week (Mondays, Wednesdays, Fridays) after the technical section of regular practice. Training volume progressed from 3 sets x 3 min (weeks 1-2) to 4 sets x 3 min (weeks 3-4) and 4 sets x 4 min (weeks 5-6), with 2-minute passive recovery between sets.
  • RSTG Protocol: Performed 20-meter linear maximal sprints with 20 seconds of active recovery (slow walking) between repetitions and 3-4 minutes of passive rest between sets. Volume progressed from 2 sets x 6 reps (weeks 1-2) to 2 sets x 8 reps (weeks 3-4) and 3 sets x 6 reps (weeks 5-6).
  • Control Group: Maintained standard soccer training sessions planned by the head coach, without any additional physical conditioning intervention.

Assessments:

Body composition parameters were evaluated via bioelectrical impedance analysis (Tanita BC-418 MA). Laboratory testing included the 30-second Wingate Anaerobic Test (Monark 834 E) with a load equal to 7.5% of body weight to assess peak and mean anaerobic power. Field testing included 10m and 20m sprint times using electronic photocells (Smart Speed Lite), change-of-direction performance via the Illinois Agility Test, and lower-body explosive power via the Countermovement Jump test (Smart Jump mat).
