Increases in Strain, Strain Rate, Displacement and Velocity in the Thoracic Aorta After Bench Pressing

  Figure 1. The study included 256 healthy participants, separated into two groups. The first group was comprised of 196 athletes; however, 18 were excluded due to difficulties with thoracic aorta visualization, resulting in a final count of 178 athletes. The second group consisted of 60 healthy men with no history of strength or endurance exercise. Of these, 30 were compared to the 178 athletes who performed the bench press, and another 30 from the control group were compared with athletes assessed at a 10-year follow-up.

  Figure 4. DTA vectorial velocity analysis. Parasternal and apical four-chamber views. The aortic border contour is drawn and explored using speckle tracking. The image displays velocities and the anatomical curved mode: (a) parasternal view; (b) apical view.

  Figure 5. “Frecuencia de rotación (Endo)” = Rotational velocity. The thoracic aorta is outlined and divided into six zones, with the systolic peak values displayed. The average systolic peak value is taken. These measurements are reported in degrees per second. In this athlete, values rose from 54°/s to 79°/s after exercise: (a) DTA rotational velocity before exercise; (b) DTA rotational velocity after exercise.
