RESUMO

Fourteen sprinter and médium-distance runners (8 men and 6 women) were inn order to avaluate the automic control of heart rate (HR) and the cardiorepiratory adaptations induced by physical training (PT) at rest and during the execution of dynamic exercise at three different times, i.e.: 1) control: after 45 days of vacation following the training program so the previous year,; 2) nonspecific PT (T1=4 to 5 months); 3) specific PT (T2 = 4 to 5 months). The test involving dynamic physical effort were of the discontinous submaximal and maximal type sitting position) An electromagnetic cycle ergometer was used, with powers of 20, 50, 100, 150 and 200 Watts (W) being applied for men and powers od 25, 50 and 100 W being applied for women during a period od 4 minutes (min) at each power. In the maximal test, additional power increments were used until physical exhaustion was reached. HR was continuously recorded, and ventilation (V) , oxgen consumption (VO2) , carbon dioxide production (VCO2) and the respiratory exchange quotient (RER) were recorded only during the final minute of each effort power. Two types of study were conducted: 1) Transversal (T), with athletes of both sexes, only during the period corresponding to their return from vacation: 2) Longitudinal (L), with 5 male athletes only, during the control, T1 and T2 periods ...Note: The complete abstract is available with the full electronic digital thesis or dissertations
