Abstract

The increase of the cavity or the thickness of the left ventricle and morphological alteration of the quadriceps occur differently depending on the sport activity being performed (aerobic or anaerobic). Thus, this present study intends to verify the proportionality of cardiac hypertrophy with peripheral muscles in athletes.This study is descriptive and exploratory with a cross-sectional and qualitative and quantitative approach. There will be 20 (twenty) high performance athlete volunteers participating, divided in two groups: 10 (ten) long distance runners (marathoners) and 10 (ten) short distance runners (100 meters free style). Each athlete will be submitted to fasting bloodwork for routine laboratory analysis. They will undergo MRI of the heart and femoral quadriceps and finally will perform a stress test using ergospirometry. By presenting samples of normal distribution with quantitative variable for the statistical analysis will be used t distribution - student (AU)
