  1. Physiological Strategies

  2. Physiological strategies is the focus of two elements- the removal of metabolic by-products and a nutrition plan to replace lost fluids and energy rich nutrients.

  3. Cool down • Is exercise to gradually reduce heart rate and metabolism to the pre-exercise state. • Elevated body functions such as ventilation rate, blood distribution and adrenaline levels return to normal. • Not cooling down can result in blood pooling, causing dizziness, muscle stiffness and soreness. • An effective cool-down should consist of 5-10 minutes of walking/jogging/slow swimming.

  4. Hydration • Fluid loss varies from one individual to another and is influenced by altitude, temperature, exercise intensity, exercise duration and sweating. • Thirst is an indicator of dehydration as fluid losses can advance more rapidly than the thirst mechanism can adjust. • Extended exercise can result in the loss of 0.5-1.5 (2%) kilograms of fluid per hour.

  6. The ability to recover after competition and training is essential in ensuring that optimal performances can be maintained. Recovery can involve a range of strategies. • When selecting the most appropriate recovery strategy coaches and athletes need to apply the principle of specificity to meet the demands of training and competition. • Physiological strategies aim to conserve body fluid levels, replace fluid as well as reduce and remove the by-products of exercise. • Neural strategies such as hydrotherapy and massage assist in waste disposal within muscle. They aim to minimise the effects of fatigue and allow for continuation of the training program. • Cryotherapy uses cold therapy in the form of ice packs, ice baths and cryotherapy chambers to reduce pain and inflammation and assist in eliminating metabolic waste. • Psychological strategies such as relaxation and sleep are as important as physiological strategies in completing total recovery following demanding physical activity. • Not all recovery strategies utilised by athletes are supported by scientific evidence.
