점프 성능을 위한 VBT: 메타분석 리뷰

Velocity-based training (VBT) has emerged as a popular method for prescribing and monitoring resistance training loads. But does the research support its effectiveness? This article summarizes a comprehensive meta-analysis examining the effects of VBT on strength and jump performance outcomes.

Orange et al. (2022) conducted a systematic review and meta-analysis published in Sports Medicine, one of the highest-impact journals in exercise science. The review included 15 randomized controlled trials comparing VBT to traditional percentage-based training.

Key study parameters:

• Participants: 479 total across all studies, ranging from recreational to elite athletes
• Intervention duration: 4-12 weeks
• Exercises studied: Back squat, bench press, and various jump tests
• Primary outcomes: Maximal strength (1RM), countermovement jump height, squat jump height, sprint performance

The meta-analysis revealed several important findings:

1. Strength gains were comparable or superior: VBT produced similar or greater improvements in 1RM strength compared to traditional training, despite often using lower training volumes.
2. Jump performance improved significantly: Countermovement jump height improved by an average of 7.2% in VBT groups, with the strongest effects seen in programs using velocity loss thresholds.
3. Reduced training volume: VBT groups performed approximately 25-40% less total training volume while achieving equal or better results.
4. Fatigue management: Using velocity loss thresholds (stopping a set when velocity drops below a threshold) helped manage fatigue accumulation more effectively than fixed set-rep schemes.

The most consistent finding was that VBT allowed athletes to achieve the same outcomes with less total work, suggesting improved training efficiency.

Based on this research, here are practical takeaways for athletes and coaches:

• Use velocity loss thresholds: A 20% velocity loss cutoff appears optimal for strength development while managing fatigue.
• Track mean concentric velocity: This is the most reliable and practical metric for daily training decisions.
• Build individual load-velocity profiles: Group averages are a starting point, but individual profiles are more accurate for load prescription.
• Monitor daily readiness: If your first-rep velocity at a given load is significantly lower than normal, it may indicate fatigue — consider reducing the load.
• Don't abandon percentage-based training entirely: VBT works best as a complement to traditional programming, providing real-time feedback to optimize daily loads.
