Direct Answer
The recovery techniques specified in IB SEHS include myofascial release, compression garments, and thermotherapy. They may reduce muscle soreness, improve mobility, or support circulation, but their effectiveness depends on the athlete, timing, duration, and type of exercise.
Mechanisms and Effects
These techniques are generally used after exercise to manage fatigue, discomfort, and delayed onset muscle soreness (DOMS). They supplement, rather than replace, essential recovery strategies such as sleep, nutrition, hydration, and sufficient rest.
| Recovery technique | Mechanism and potential effects | Limitations |
|---|---|---|
| Myofascial release | Pressure is applied to muscles and fascia, commonly through foam rolling or massage. This may reduce perceived tightness, increase range of motion, and temporarily decrease soreness without substantially reducing later performance. | The precise physiological mechanism remains uncertain. Excessive pressure may cause pain or tissue irritation. |
| Compression garments | Elastic clothing applies external pressure to a limb. This may improve venous return, limit fluid accumulation, reduce swelling, and support the removal of metabolites through circulation. | Improvements in performance recovery are inconsistent, and some benefits may be perceptual or psychological. Correct garment fit is important. |
| Thermotherapy | Heat is applied using warm baths, heat packs, or heated environments. Increased tissue temperature causes vasodilation, which increases local blood flow and may improve tissue extensibility and reduce stiffness. | Heat should not be applied immediately to an acute injury involving inflammation or swelling because increased blood flow may worsen these responses. |
None of these techniques directly removes all causes of fatigue. For example, they do not immediately restore depleted muscle glycogen or repair exercise-induced muscle damage; nutrition and rest are required for those processes.
Exam Technique
For A.3.3 Fatigue and recovery (HL), distinguish between describing a technique and explaining its mechanism. An effective response should identify the method, explain a relevant physiological effect, and state a limitation. Avoid the misconception that reduced soreness necessarily means complete physiological recovery or improved subsequent performance.
