Introduction: Lactate threshold below (Wasserman et al, 1973), in healthy individuals, physiological responses are stable, because the systems get to meet energy demand, so, there is a balance between consumption and supply of oxygen (Brooks, 1991), however, above the intensity LA observed slow increase in HR as a function of time due to the high concentration of lactate. These adjustments are well established during aerobic exercise, but lack evidence during resistance exercise. Objective: To investigate the settings of SBP and DBP below and above the lactate threshold during resistance exercise on a diabetic and hypertensive woman. Method: Was studied a woman of 55 years, hypertensive and diabetic. The heart rate was recorded during the protocol using a digital telemetry system previously validated (LOIMAALA et al, 1999; GAMELIN BERTHOIN, BOSQUET, 2006), consisting of a transmitter positioned at the height of the xiphoid process, and a monitor / receiver (polar RS800CX, polar Electro Oy, Kempele, Finland).The anaerobic threshold (AT) was determined during the performance of knee extension exercise in the Roman table. Voluntary performed 20 repetitions for one minute with 10% load obtained in the 1RM test and after stopping test blood was collected on the earlobe for lactate analysis. This same procedure was performed in series with subsequent increase of 10% in 10% of the maximum load to that observed up to the value correspondent fixed 4 mmol.L lactate, which was considered as the lactate threshold (DENADAI, 1995; HECK et al,1985).. The HR and R-Ri were recorded continuously for 65 seconds at rest, during isotonic contraction and 5 minutes of recovery. From these data were studied adjustments in systolic blood pressure and diastolic blood pressure at rest and during exercise. Results and Discussion: We used for this study intensities 10%, 20% and 40%, which data were obtained, respectively, resting SBP = 128, 121 and 133 rest DBP = 81, 76 and 92, HR rest = 70 14, 68.91, and 67.09. SBP year = 146, 161 and 234. DBP exercise = 95, 109 and 158 HR exercise = 80.64, 84.57 and 90.74. Variation in SBP = 18, 40 and 101. Variation DBP = 14, 33 and 66. Variation HR = 11.82, 17.79 and 26.36. The results of the study are in agreement with the literature when they show a considerable increase in HR, SBP and DBP. Conclusion: The increase in DBP and SBP are disproportionate load at intensities above the AT.
