Lipid peroxides can be both a product and an initiator of oxidant stress. Conceivably, exercise can either increase concentrations of lipid peroxides (by causing oxidant stress), or decrease them (by accelerating peroxide breakdown). The net effect could depend on exercise intensity and nutritional intake of antioxidants. The present study examined the response of serum lipid peroxides to the c...

T h i s report describes a procedure that permits accurate and specific measurement of lipid peroxides by iodimetry in the small samples available in many biological studies. Martin’s review (1) of methods for determination of organic peroxides indicates that most methods are based on reactions with various reducing substances. The most serious drawback of methods other than iodimetry can be as...
