Skating Quadrennial Cycle & Comeback Planner

ISU Periodization Engine
Source Context: Alysa Liu announced a 1-season competitive hiatus (“Fear not, I’ll be back.”). Model how strategic rest optimizes recovery runway, jump longevity, and peak Olympic form.

4-Year Quadrennium Periodization & Trajectory

Biomechanical & Readiness Telemetry

Olympic Peak: M48
Cumulative Jump Stress 420 kN Impact force vs joint fatigue ceiling
Injury Risk Index Low (18%) Derived from rest-to-load ratio
PCS Artistic Growth +6.8 pts Maturity & choreography runway
Peak Comeback Form 94.2% Free Skate stamina & jump consistency
Strategic Comeback Viability: OPTIMAL
The 12-month hiatus allows systemic joint decompression while reserving a 10-month intensive reconditioning runway before Grand Prix and World Championship trials.
Phase 1: Active Recovery & Reset Month 0 - 6: Light stroking, edge depth, injury healing
15% Load
Phase 2: Season Hiatus & Artistry Month 6 - 18: Choreography workshops, non-impact cardio
30% Load
Phase 3: Technical Reconditioning Month 18 - 28: Triple Axel drills, jump combinations
75% Load
Phase 4: ISU Championship & Olympic Peak Month 28 - 48: Competitive simulations, max stamina
95% Load
