title: The effect of weight lifting exercise on heart rate and metabolism in experienced weight lifters.
abstract: Fifteen experienced weight lifters were investigated to examine the effects of weight exercise with variable intensity on heart rate and changes in arterial glucose, lactate and pyruvate, as well as serum total lipids, beta-lipoproteins, triglycerides, glycerol and free fatty acids. The highest value of heart rate were reached during repetitions (ca. 150 beats/min), during single maximal contraction only 120--130 beats/min. No important changes were found in lipid substrates or glucose, while lactate (x max: 4 mmol/l) and urivate (x max: 0.11 mmol/l) increases were moderate. This type of training may be useful in the clinical rehabilitation of the locomotor system but it lacks importance for preventive or rehabilitation therapy of the cardiovascular system.
