Key result
Elite athletes engaged in high dynamic sports with moderate or high static components showed significantly reduced left ventricular basal rotation and twist compared to non-athletic controls (P<0.05).
Why the study?
The study was designed to test whether differences in LV rotational mechanics could be detected in elite athletes engaged in high dynamic sports with different static components in their training.
Does high dynamic sports training with varying static components alter left ventricular rotational mechanics in elite athletes compared to non-athletic controls?

Does high dynamic sports training with varying static components alter left ventricular rotational mechanics in elite athletes compared to non-athletic controls?
Elite athletes engaged in high dynamic sports with moderate to high static components exhibit reduced left ventricular basal rotation and twist on 3D speckle-tracking echocardiography.
Reduced LV basal rotation and twist in high-dynamic/moderate-high static athletes may reflect adaptation; leaves open clinical relevance and need for outcome studies.
BACKGROUND: In normal circumstances while left ventricular (LV) apex rotates counterclockwise, LV base has a clockwise movement at the same time. This sort of towel-wringing-like movement is called LV twist. The present study was designed to test whether differences in LV rotational mechanics could be detected in elite athletes doing high dynamic sports with different static components in their training. METHODS: The subject group comprised 80 elite sportsmen. The following groups were created regarding their physical activity: group CI (high dynamic/low static)(N.=13, mean age: 24.0±5.1 years, group CII (high dynamic/moderate static)(N.=23, mean age: 24.6±7.7 years) and group CIII (high dynamic/high static)(N.=34, mean age: 22.8±6.0 years). Their results were compared to 67 age- and gender-matched non-athletic healthy controls (mean age: 24.0±5.1 years). Three-dimensional speckle-tracking echocardiography was used for the evaluation of LV rotational abnormalities. RESULTS: Reduced LV basal rotation was seen in group CII and CIII subjects compared to the control group (-4.31±1.82 degrees vs. -3.17±2.81 degrees and -2.88±1.88 degrees, P<0.05 and P<0.05, respectively). It was accompanied with LV twist reduction in groups CII and CIII subjects compared to the control group (14.0±3.4 degree vs. 11.3±4.3 degrees and 11.5±4.1 degrees, P<0.05 and P<0.05, respectively). None of the elite athletes showed absence of LV twist called as LV "rigid body rotation." CONCLUSIONS: Significant LV rotational abnormalities including reduced LV basal rotation and twist could be detected in elite athletes doing high dynamic sports with moderate/high static components in their training.

Gyenes et al. (2021) conducted a cross-sectional in Elite athletes (n=147). High dynamic sports with moderate or high static components vs. Non-athletic healthy controls was evaluated on LV basal rotation (degrees) (p=<0.05). Elite athletes engaged in high dynamic sports with moderate or high static components showed significantly reduced left ventricular basal rotation and twist compared to non-athletic controls (P<0.05).
