Program Design and Periodization Using Biomechanical Principles
This domain tests program design through biomechanics: specificity, overload, exercise selection, sequencing, volume, intensity, and periodization. Items ask you to choose the variable that best matches the goal.
Core rules
- SAID principle: specific adaptation to imposed demands. The program must resemble the target movement's joint angles, velocities, and contraction types.
- Progressive overload can come from load, volume, range, density, or complexity; change one or two variables at a time.
- Mechanical tension, muscle damage, and metabolic stress drive hypertrophy; force and velocity drive power.
- Exercise order affects performance: complex, high-force movements before fatiguing isolation work.
- Periodization organizes training into phases. Linear progression raises intensity and lowers volume; undulating changes stressors more frequently; block periodization concentrates loads.
- Deloads reduce accumulated fatigue while preserving technique and intent.
Worked example
A basketball athlete needs vertical power. A block starts with squat and trap-bar deadlift for force, then progresses to jump squats and depth jumps for RFD, while maintaining hip and ankle mobility. Weeks 1–2 use 3×5 at moderate-heavy loads and low plyometric volume; weeks 3–4 reduce strength volume and add low-amplitude pogos and box jumps. The reasoning: build force first, then express it quickly, while keeping contact quality high. A program that adds plyometrics and heavy squats simultaneously at high volume risks fatigue and poor landing mechanics.
Traps
- Randomly varying exercises and calling it periodization.
- Copying a program without matching the target velocity and range.
- Increasing volume and intensity in the same week indefinitely.
- Ignoring technique fatigue as a reason to deload.
