Подробное описание
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).
