•To improve recovery aspects, hydration strategies should seek to optimize hydration status continuously, and not solely around competition schedules.

Self Myofascial Release
•Fascia is a specialized connective tissue layer surrounding muscles, bones and joints and gives support and protection to the body.
•Fascia is one of the 3 types of dense connective tissue (the others being ligaments and tendons) and it extends without interruption from the top of the head to the tip of the toes.
• Trigger points in the fascia may restrict or alter the motion about a joint resulting in a change of normal neural feedback to the central nervous system. Eventually, the neuromuscular system becomes less efficient, leading to premature fatigue, chronic pain and injury and less efficient motor skill performance.

Self Myofascial Release
•Self myofascial release is a simple technique that we can all use to alleviate trigger points. Studies have shown myofascial release to be an effective treatment modality for myofascial pain syndrome, although most studies have focused on therapist-based rather than self-based treatment.

Athletes who may be more susceptible to experiencing overtraining include:
• Younger athletes
• Less developed coping skills
• Experienced an injury or performance slump
• Have perfectionist tendencies
• Demonstrate a high need to please others
• Display a high athletic identity (only see themselves as being an athlete)
• Perceive many situations where high demands or expectations are placed on them

Prevention
•Early detection of changes in mood, self-confidence, energy level and sleep all can help prevent training slumps.
•One of the best methods of improving recovery habits and reducing the likelihood of overtraining is appropriate athlete education.

1. Listening support – perception that one is listening without giving unrequested advise or being judgemental
2. Emotional support – perceptions of unconditional care and comfort
3. Emotional challenge support – perceptions that one is being challenged to evaluate their own attitudes, values and feelings for the purpose of positive growth
4. Reality confirmation support – perception that someone else sees things in a similar manner or has had a similar experience
The following seven categories can help reduce stress during recovery (this support can come from multiple sources – trainers, parents and friends)

DOMS
Delayed Onset Muscle Soreness is the pain and soreness arising from the damage and repair processes and is a result of unaccustomed exercise traditionally with a high eccentric focus.
The duration of DOMS is directly related to the exercise overload, amount of tissue damage and the fitness level of the athlete. Typically pain is at its peak between 24-72 hours, but it can last as long as 10 days.

•Continuous running is an example of overused training strategy that provides exceptionally low transferability to most sports while creating counterproductive effects in important muscle tissue and physiological systems (Kraemer).
• Long slow-distance movements is likely to create stress that does not strongly benefit strength, speed and power performance, yet can interfere with vital performance aspects of most sports (speed, strength, power) and it can create an even more detrimental effect on recovery.

Ice Bath
• It is recommended that a range of 10°C – 15°C (50°F-60°F) for cold water is the optimal range for cooling soft tissues. Colder temperatures used for long periods risk damage to soft tissues and are not recommended for tennis recovery.
•10-15 minutes is a recommended time frame

Spas
•Spa use has had little scientific investigation and most reports are anecdotal. No definitive guidelines for time or even water temperature have been set, but excessive time-periods in hot water can leave the athlete feeling lethargic and “flat”.
•The temperature ranges for warm immersion vary from core-temp neutral 34-38°to 42°C (93-108°F) as the upper limit with most studies employing 37 -38°C (97.6-100°F) as the examined upper temperature range.

Contrast Shower
•Contrast water temperature protocols use much shorter exposure times with warm immersion lasting 1 to 3 minutes and cold water immersion ranging from 1 to 2 minutes.
•Very practical as can be performed in any shower.

Sauna
• Sauna use (hot and dry heat) is not well understood and can be misused.
• The traditional protocol involves a warm shower followed by a sauna for 5 minutes (40°C/ 104°F) with cold plunge (10°C/ 50°F) for 30-60 seconds, repeated 3-5 times. The aim is to depress activity in the central nervous system to prevent over-stimulation following high intensity training, such as rapid or complex decision making in conjunction with heavy training loads.
• There is a lack of published research on the performance benefits of sauna use, and as many players misuse the modality it is often not recommended for use by young athletes. Certain national training centers restrict the use of saunas to athletes over 15 years of age.

Massage
• Although massage does feel good and provides a sensation of reducing tight muscles, little scientific evidence is available to support claims such as:
– improved blood flow – improved muscle strength – significant reductions in muscle
soreness
• However, many studies have shown an improvement in psychological factors such as mood and well-being.

Acupuncture and Acupressure
• Acupressure and acupuncture focus on applying pressure (or needles) to specific reactive points along meridians. The anatomical location of these meridians varies according to cultural and historical contexts from which they were derived (Chinese concepts of Ying-Yang and Qi and Indian concepts of Chakras.)
• Very few studies have been published in reputable Western scientific journals, so the evidence is limited.
• However, at least one reputable study has demonstrated a significant relaxation response in the skeletal muscle of athletes in response to acupuncture treatment.
• Mechanisms are still unclear and at best are supplemental or adjunct treatments alongside more conventional recovery modalities.

Compressive Clothing
• Compressive garments have been shown in certain circumstances to reduce injuries, benefit performance and enhance recovery.
• The benefits stem from graduated pressures which extend from the limbs to the core of the body.
• Studies have shown reductions in post-exercise edema following eccentric work (stop and start movements, deceleration activities), muscle soreness.
• There is also a reduced perception of fatigue. • These compression garments aid in recovery, but do not
improve performance if worn during practice or matches – they may even reduce performance during play.
