As we talk about the day yesterday, exercise for hypertension is a somewhat sensitive issue, although very positive if done with the right prescription. Movements of strength in certain positions and, above all, isometric contractions can shoot blood pressure up to limits frankly risky.
What is an isometric contraction? To understand us, is when do force without moving (or shortening or lengthening muscle). For example, if you push a wall without moving, you’re doing strength and, unless you do much and get moving the septum… is a contraction in static. This is exactly an isometric contraction.
The Pilates method, as well as formerly Swedish gymnastics, is based on many of these contractions in balance to activate the muscles deep (trasverso abdominal, pelvic floor, etc.) as a stabilizer in movements of balance. What happens when a hypertensive performed these exercises?
I refer to a study published in Buenos Aires by Easter, Andres; Donato, Martin; Borrego, Carlos; Gabay, José; Berrocal, Daniel; J. Gelpi, Ricardo; Grinfeld, Liliana on the “evaluation of diastolic function during and post-exercise isometric in patients with arterial hypertension” which thus titled.
It is known that patients with ventricular hypertrophy by arterial hypertension have diastolic alterations, particularly during exercise. However, it is controversial if this dysfunction is normalized after the effort.
The objective was to assess the diastolic function during and after exercise in patients with arterial hypertension. Studied 6 patients (Group 1, G1) controls and 7 with a diagnosis of hypertension (Group 2, G2).
The patients underwent a cardiac catheterization and made isometric during the study period, until the heart rate increased a 43 with a margin of 7% (p < 0.05), with respect to the baseline. Systolic left ventricular (PSVI) and end of diastole (PFDVI) pressure were measured and calculated the maximum speed of rise of pressure (+ dP/dtmax), the time constant of the ventricular pressure tau, the time taken to fall pressure up to 50% of its value at the time of the – dP/dtmax (t1/2 (, msec).
The PSVI increased, during the exercise, from 140 to 195 more or less more or menos14 mm Hg (p < 0.05) in G1 and 161 a9 until 238 more or less 15 mm Hg in G2; then returned to basal susvalores. Tau and t1/2 increased by G2, during the year, from a value of 23mas or minus 2 and 15 more or less msec to 35 with a margin of 7 and 23 more or less 4 msec, respectively.! After the effort, both variables remained elevated with respect to the baseline, reaching values of 41 more or less 6 msec (p < 0.05) and 23 more or less 3 msec (p < 0.05), respectively.
Isometric exercise slow relaxation and increases the PFDVI in patients with hypertension and left ventricular hypertrophy. After the exercise the relaxation was altered, while the rest of the haemodynamic variables returned to its baseline, suggesting the presence of stunning myocardial (AU)
Now we will see in the following table according to age and sex to what can be understood as hypertension and at what scales are going to consider risk.
< li > of 16 to 18 years: 145 and 140 respectively in boys and girls as Maxim and 90 as a minimum. < /li > < li > from 19 to 24 years old: 150 and 140 respectively in boys and girls as Maxim and 95-90 as a minimum. < /li > < li > from 25 to 29 years old: 150 and 140 respectively in boys and girls as Maxim and 96 and 92 as a minimum. < /li > < li > 30 to 39 years old: 160 and 150 respectively in boys and girls as maximum and 100 and 98 as a minimum. < /li > < li > 40 to 49 years: 170 and 165 respectively in boys and girls as Maxim and 104 as a minimum. < /li > < li > of 50 onwards: from 180 in both cases as Maxim and 110 as a minimum. < / li & gt;
Such high levels of blood pressure can produce stroke, thrombosis, or even miocardia infarctions, becoming a really risky practice, so we strongly recommend that you take on a regular basis the tension if you think you can come into this group and do weight training, lift weights or pilates exercises.
