Morphological and functional changes in athletes' hearts during the competitive season.
This research aims to determine the cardiac morphological and functional changes that occur during the competitive season in elite athletes with previously-induced adaptive changes. Two echocardiographic examinations were performed in each player of a senior professional football team, the first at the beginning of the training phase and the other at the peak of the competitive season. It was demonstrated that after the brief period of deconditioning during the holiday period, further changes took place, even in these athletes with several years of prior professional activity. There was a significant increase between the two assessments in left ventricular wall thickness and mass, and in left atrial diameter, but left ventricular diastolic diameter and the diastolic function parameters consideredof a hill. In the construction of the arterial highway east of the intersection, a cut had been made in the hill, leaving a dirt embankment on the north side thereof. A driver from the east must travel upgrade a distance of six hundred fifty feet until the intersection is reached. A driver from the north must also ascend a hill, the crest of which, according to the testimony most favorable to the appellants, was one hundred twenty-five feet from the intersection. The highway between the crest of the hill to the north and the intersection was level. The accident happened in winter. Snow had been graded out of the highways so that in addition to the dirt embankment on the north side of the east-west highway there
