Document Summary

Low intensity activity assists blood circulation, helps remove lactic acid from muscle: active rest allows athlete to physically & psychologically recover from training while maintaining fitness levels, cross training. Increased muscle relaxation as a result of decrease in excitability of motor neuron pool. Cryotherapy decreases skin, subcutaneous, and muscle temp, resulting in narrowing of blood vessels (vasoconstriction: beneficial effects include, reducing sensation of pain, limiting amount of swelling, reducing muscle spasm, clearing metabolites from superficial/deep tissues. Thermotherapy has opposite effect, increasing tissue temp, resulting in expansion of blood vessels (vasodilation: beneficial effects include: Increasing oxygen/antibody supply: reducing muscle spasm, clearing metabolites. Contrast bath (alternating hot & cold) in theory promotes rapid alternation between vasodilation and vasoconstriction, causing pumping action in peripheral circulation. Influences on athletic performance: equal lactate level and perceived level of recovery as active recovery, quicker perceived level of recovery than passive recovery, sanders, 1996.
