PURPOSE: To study the modifications induced by physical training (PT) using upper limbs in aerobic condition of short duration on cardiovascular and metabolic variables. METHODS: Eleven paraplegic persons, with a mean age of 59 years, 7 men and 4 women with lesions at T9 through T11 and mild hypertension (HAS) were studied. The patients were studied before and after 12 weeks of a supervised program of PT, through exercise tests in a mechanic ergometer (ST) adapted for the arms. We emploied an intermittent protocol with stress increments of 125 (20w) and 140kgm/min (25w) for women and men, respectively every 3min. The ergometric speed ranged from 83 to 95rpm. The oxygen consumption (VO2) was estimated according to American College of Sports Medicine equation for arms. The exercise intensity during the TF program was estimated through the Karvonen cardiac frequency reserve, with a variation of 65% to 85% and the Borg stress scale of subjetive perception during the stress test. RESULTS: The mean maximal aerobic capacity increased in 22% (930+349 vs 1138+290mL/min; p=0.003); there was a reduction of systolic and diastolic pressures at rest and after submaximal exercise of 4%,15% and 5% and 5%, respectively. CONCLUSION: Physical training of mild to moderate intensity using the upper limbs in paraplegic persons, besides inducing functional capacity increment , is an important model of non drug control of the hypertensive response.
