Fig. 1From: Assessment of left ventricular systolic function by non-invasive pressure-strain loop area in young male strength athletesa Non-invasive LV PSL diagram of the athlete group. The red loop area represented the average LV global MW index and the green loop area represented MW of basal inferior. b 17-segment bull’s-eye representation of GLS in an athlete. c The MW of global average and basal inferior in an athlete with the green representing constructive work and the blue expressing wasted work. d 17-segment bull’s-eye expression of GWI with areas of normal in green and high in red.
