INFLUENCE OF BODY POSITION ON CARDIAC OVERWEIGHT IN SUPINE EXERCISES

Abstract

According to the Brazilian Society of Cardiology (2005), the muscular strength is fundamental to health, for maintenance of a good functional capacity and to achieve satisfactory quality of life. Several cardiovascular alterations occur during the exercise, specifically on the resisted exercise and this one leads to cardiac overweight, that can be seen through the double product. Then, this study aimed to analyze possible differences on the cardiac overweight related to the body position through the double product on the supine exercises, straight, inclined and downward inclined ones. Therefore, 21 individuals with an average age of 23 years old (±2 years), body mass of 85,4 kilograms (±6 kilograms) and  middle height of 176,3 cm (±5 cm) were analyzed. The observed variances were the systolic arterial pressure (mmHg) and the cardiac frequency (beats/min). For data collecting,  it was used a POLAR frequency measurer, as well as an aneroid arterial pressure measurer and a stethoscope from MORE FITNESS for systolic and diastolic  arterial pressure at the end of a series of supine exercises. At the hemodynamic variables observed, the straight supine was the one which presented the greatest values in comparison to the other exercises, however, the results doesn't show statistical differences among themselves, being necessary a new study with a greater and homogeneous sample to identify the presented data more precisely as well as other kinds of exercises and training methods, in order to act with safety on the physical activities prescription.
