Inhibit, Lengthen, Activate, Integrate (ILEA) Corrective Program Design
Inhibit, Lengthen, Activate, Integrate (ILEA) Corrective Program Design
This domain tests the four-phase corrective sequence and the parameters that make it usable in a session: inhibit, lengthen, activate, integrate. Expect order-of-operations questions, exercise selection, and progression logic.
Core rules
- Inhibit: self-myofascial release or manual pressure to reduce overactivity in a tight or overactive tissue. Typical dose: 30-60 seconds per area, slow pressure; avoid acute injury, varicose veins, or numb and tingling areas.
- Lengthen: static or neuromuscular stretching for the tissue identified as short. Typical dose: 1-3 sets of 30 seconds; avoid aggressive end-range stretching in hypermobile clients.
- Activate: isolated strengthening for the weak or inhibited muscle, low load, high control. Typical dose: 1-3 sets of 8-15 reps with a 2-4 second hold or slow tempo.
- Integrate: retrain the whole pattern with dynamic, multi-joint movement that includes the activated muscle and the corrected posture. Low-to-moderate load, quality over fatigue.
- Sequence matters: reduce tone, restore length, wake up the weak link, then teach the pattern. Do not fatigue the client in activation and expect clean integration.
- Program frequency: 2-4 corrective sessions per week, or brief blocks within regular training, reassessing every 2-4 weeks.
Worked example
A client with knee valgus and foot flattening in the overhead squat. Inhibit: plantar fascia and calf. Lengthen: calf and hip flexor. Activate: tibialis posterior, gluteus medius, and intrinsic foot. Integrate: split squat with a neutral foot and knee tracking. Reasoning: the order matches the tissue state; integration uses the exact screen that failed.
Traps
- Skipping inhibit and lengthen because activation feels productive.
- Using heavy loads in integration before control is present.
- Random exercise selection that does not match the screen finding.
