In the first half of pregnancy diet women are not too different from the normal rules adopted for rights. During this period, there is a formation of the unborn child – must see to it that the body received a sufficient number of proteins, fats and carbohydrates. Doctors consider it advisable to use 110 g protein, 75 grams fat and 350 grams of carbohydrates in the total daily energotsennost in 2400-2700 cal. Nutrients. In the second half of pregnancy begins to increase nutrient requirements – is now the body to 120 g protein, 85 g fat and 400 grams of carbohydrates.

In the diet of pregnant women should include enough animal protein: milk, yogurt, cottage cheese, fish, meat, cheese (low fat, and mild), eggs (no more than one day).

We also compared the mean values (SBP and DBP) and (DP) cross will be to year and leg press 45, was in significant difference in mean SBP (p = 0,014) obtained in two different years. Therefore, it is necessary will be to other studies analyzing different body positions, only that by comparison we can establish conduct you these exercises. Keyword: resistance exercise, heart rate, blood pressure, double product. Introduction Currently, the cardiovascular 0 variable come being monitored to directly indicate the impact of the intensity of effort and the modality of exercise on the tax of work of miocrdio1. The cardiac frequency (FC), sistlica arterial pressure (SHOVELS) and the diastlica arterial pressure (PAD) are the used 0 variable more, and associates supply the double product (DP) that she allows to evaluate of indirect form the work of miocrdio2. For in such a way the use sends regards of the double call product or MTTS (Modificated Tensio Time Index), for resultant numerical parameter of the multiplication of (SHOVELS), express in mmHg and for (FC), express in bpm.

Thus, as apontam3 is interesting the use of (DP) as a parameter of security to observe where types of activities the cardiovascular system is displayed to the biggest work and, therefore, the biggest risks. In a carried through study, it showed that 0 variable (FC) (Par) if modify due to corporal position where the individual carries through exerccio4. The excellent alterations can occur in these parameters with significant changes in exercises that involve superior and inferior members. The same ones emphasize that changes in the position (involving the corporal pursuings above cited) can increase the venoso return and with this, to cause significant changes the hemodinmicas answers.
