Undulating Periodisation¶

Undulating Periodisation là model conditioning thay thế Linear Periodisation Failure trong ATP calendar: thay vì sequential phases (base → power → peak), tất cả physical qualities được developed concurrently, với load và intensity undulating (dao động) theo tournament schedule mỗi tuần.

Nguyên Lý Cốt Lõi¶

Concurrent Training¶

Thay vì "build strength first, then power, then sport-specific" — player train tất cả qualities simultaneously mỗi tuần: - Explosive power (plyometrics, medicine ball, sprint intervals). - Neuromuscular strength (micro-loads, isometric holds). - Eccentric deceleration capacity (braking mechanics, labral protection). - Aerobic maintenance (enough to support recovery between efforts — not primary focus).

Concurrent training nghĩa là không có một quality nào bị neglected trong tournament block — không có "I'll work on strength in the off-season" thinking.

Undulating Load — Tournament-Week Structure¶

Week Type	Volume	Intensity	Focus
Preparation block (3–4 tuần)	High	High	Full development sessions — plyometrics, strength, sprint intervals
Tournament week	Very low	Low-moderate	Micro-Loading only — activation, no accumulative fatigue
Post-tournament recovery	Low	Low	CNS recovery — movement and light technical work
Development block (between tournaments)	High	High	Return to full development

Undulation means the programme adapts to what the calendar demands, not what the linear model prescribes.

12-Week Template — Ivancevic Framework (2026 Updated)¶

The programme adapted from the Ivancevic et al. 12-week tennis performance framework integrates three simultaneous tracks:

Track 1 — Physical Conditioning¶

Weeks 1–4: Sprint interval foundation, Eccentric Deceleration Training, plyometric base.
Weeks 5–8: Type IIb Fast-Twitch Optimisation, contrast training (heavy → explosive same session).
Weeks 9–12: Match-intensity simulation, Micro-Loading maintenance, CNS monitoring intensified.

Track 2 — Technical Development¶

Stroke technical work concurrent with physical — not separated.
Key principle: Technical work done under physical fatigue = match-realistic training. Pure technical work in fresh state = practice-only engrams.

Track 3 — Tactical & Cognitive¶

Neural Pressure Training — chess work, decision drills under fatigue — concurrent with physical.
Pattern drilling integrated into conditioning circuits (hit forehand pattern → sprint recovery → repeat).

Tournament-Week Protocol — Critical Detail¶

Biggest linear periodisation error: treating tournament week like a normal training week with match play added on top.

2026 standard: Tournament week = Micro-Loading only: - Day before match: 15–20 min activation, no loading. - Day after first-round match: Recovery protocol, not standard training session. - Between consecutive day matches: CNS-only work.

"The second model [standard training + match play] produces CNS Fatigue by the fourth day of a tournament."
