IB Sports, exercise and health science A.3.3.5 Recovery Techniques and Factors Influencing Recovery Quality Notes

Recovery Technique Categories

1. Recovery techniques fall into two broad groups: physical and physiological methods that act on the body, and psychological methods that act on the mind.
2. Most athletes combine several approaches within a single recovery routine.
3. Physical and physiological methods include cryotherapy (ice packs, cold whirlpools, cryo-chambers, cold water immersion, cooling jackets), thermotherapy, contrast water therapy, massage, foam rolling, compression therapies, neuromuscular electrical stimulation, whole-body vibration, and hyperbaric oxygen therapy.
4. Psychological methods include progressive muscle relaxation, imagery, autogenic training, listening to music, breathing exercises, and prayer.
5. Beyond formal techniques, communication with coaches and time spent with family and friends contribute to overall recovery.

Active and Passive Recovery

1. Passive recovery involves complete rest with no voluntary movement.
2. For short maximal sprint repetitions under 6 seconds, passive recovery is preferred because phosphocreatine resynthesis relies on oxidative restoration during rest.
3. For longer sprints aimed at developing glycolytic capacity, active recovery between efforts is more effective.
4. When performance must be repeated within 30 minutes, active recovery is the preferred option, since it produces a faster return to resting blood lactate and an earlier return to resting pH.
5. For longer recovery periods spanning hours, days, or weeks, passive recovery and rest are more appropriate, because prolonged low-intensity activity can compete with glycogen replenishment.

Evaluation of Recovery Techniques

Effective recovery methods help reduce muscle fatigue, improve circulation, remove metabolic waste, and decrease the risk of delayed onset muscle soreness (DOMS).

Myofascial Release

1. The fascia can become tight and restricted due to exercise, poor posture, injury, or stress.
2. Myofascial release helps reduce stiffness, enhance flexibility, and promote muscle recovery.

How Myofascial Release Improves Recovery

Myofascial release techniques include:

1. Foam rolling increases muscle temperature slightly and improves short-term flexibility; the mechanism beyond perceived benefit is debated.
2. Massage therapy improves perceived recovery, reduces cramps and tightness, and increases tolerance for subsequent exercise, while evidence for accelerated metabolite removal is weak.
3. Stretching (static and dynamic) reduces muscle stiffness and tightness, and improves joint range of motion and overall flexibility.

Effects on Muscle Tension and Circulation

Compression Garments

1. Compression therapy involves wearing tight-fitting garments that apply pressure to muscles, improving blood circulation, reducing muscle swelling, and minimizing movement-related muscle damage.
2. This aids in muscle recovery by minimising inflammation and enhancing oxygen delivery to tissues.

How Compression Garments Aid Recovery

1. Compression enhances venous return, helping remove metabolic byproducts such as lactate and carbon dioxide.
2. Compression reduces swelling by preventing fluid accumulation and stimulating lymphatic drainage.
3. Compression minimises muscle oscillation, reducing microtrauma by stabilising muscles during movement.
4. Compression helps prevent DOMS (delayed onset muscle soreness) by reducing inflammation and speeding up muscle repair.

Thermotherapy (Heat and Cold Therapy)

Cold Therapy (Cryotherapy)

1. Cryotherapy is the use of low temperatures to decrease inflammation, muscle soreness, and swelling after intense physical activity.
2. It is commonly applied through ice baths, cold compresses, or whole-body cryotherapy chambers.

Types of Cryotherapy Techniques

1. Ice baths (10 to 15 minutes at 10 to 15°C) are used post-exercise to reduce muscle inflammation and soreness.
2. Cold compresses (localised application) target specific injuries such as sprains and strains, to reduce pain and swelling.
3. Air cryotherapy chambers operate between -85 and -195°C with exposures of 1 to 3 minutes.

Cold Water Immersion and Air Cryotherapy

1. Cold water immersion involves submerging part or all of the body in cold water for typical durations of 5 to 30 minutes.
2. Cold water immersion is more effective than active recovery, contrast water therapy, or warm water immersion for reducing muscle soreness (including DOMS) and improving muscular power.
3. Cold water immersion is effective for restoring endurance performance one hour after a session, especially in warm-to-hot environments.
4. Air cryotherapy exposes the body to extremely cold air between -85 and -195°C, with exposures of 1 to 3 minutes inside a chamber.
5. Air cryotherapy is more effective than cold water immersion for immediate recovery of muscular power and recovery of muscular strength.
6. Access to cryo chambers is limited compared with water-based methods, restricting everyday use to well-resourced settings.

Heat Therapy

Heat therapy involves the use of warm temperatures to increase blood flow, relax muscles, and improve tissue elasticity.
