Effect of knee extension that runs in a manner that blood pressure in unit and bilateral

Abstract

For a safe lapsing of the force exercises, some physiological parameters must be controlled so that the reply of the blood al pressure (BP) not it raises in surplus, causing risks to the health of the practitioner. Therefore, the objective of the study was to verify the variations of the bloom pressures systolic (BPS) and diastolic (BPD), during and after the extension of the knee of form unit and bilateral. Ten individuals (26,9 ± 4.1 years; 74,1 ± 9,4kg; 171,5 ± 8,1cm), volunteers, healthful and experienced in the force training made three series of 70% of 10 maximum repetitions of the extension of the knee, in extension chair, of form unilateral (UN) and bilateral (BI). The arterial pressure was surveyed by the listen method before initiating the first series, to the end of the last series and 5 minutes after the ending of the exercise. The gauging had shown that the percentile variation in relation to the rest (Δ%) of the BPS was bigger of the bilateral repetition (BI = 39.66%) that in the unilateral (UN = 26.81%). At the BPD, the percentile variation also was bigger in the bilateral (BI = 13.38%) that in the unilateral (UN = 6.29%). Five minutes after the exercise, the average values of the BPS had after been equal to the rest in the unilateral exercise, being that in bilateral a BPS it presented a bigger value (BI = 4.31%) in comparison to the rest. Apparently, the form of execution of the unilateral extension of the knee would not re-echo on the acute cardiovascular answers, during or after the exercise. However, the bilateral execution showed trend to raise the values of BPS and BPD in relation to the unilateral execution, what it must be considered in the lapsing for people who need cares special.
