Episode notes
Repetition Duration Reserve Explains Fatigue
- Repetition duration reserve scales with intensity: max ~10s, 90% ~20s, 80% ~40s, roughly doubling per 10% drop.
- Staying below ~50% of that reserve enables multiple near-max efforts and less central fatigue.
Use Isometrics For Position-Specific Strength
- Use position-specific isometrics (±~10° joint angle) to improve strength for task-specific positions like running posture.
- Apply mid-thigh pulls or unilateral iso pushes to gain strength without unwanted hypertrophy for weight-sensitive athletes.
Contrast Isometrics With Plyometrics
- Pair isometrics as contrast exercises before plyometrics to prime the nervous system and boost jump performance.
- Use heavier overcoming isometrics like mid-thigh pulls before drop jumps or band-assisted jumps for acute gains (~1–3% typical).
