ABSTRACT
Background:
According to the ESC guidelines, sport disciplines are classified in relation to the predominant component (skill, power, mixed and endurance), including a wide range of disciplines with different isometric/isotonic exercises and exercise-induced heart remodeling. The aim of our study was to evaluate differences in morpho-functional cardiac adaptations in power athletes, comparing judokas with weightlifters.Methods:
We enrolled 55 Olympic athletes (38 judokas, 17 weightlifters), aged 24.5 ± 3.8 years, 25 (45.4%) of whom were males, and they underwent a pre-participation evaluation, including a physical examination, ECG, transthoracic echocardiogram, and exercise stress test.Results:
The judokas presented significant differences in cardiac adaptations, with larger left ventricle (LV) end-diastolic and end-systolic volumes indexed (LVEDVi, p = 0.002 and LVESVi, p = 0.004) and higher LVMass values indexed (p = 0.033), but similar LV wall thicknesses (p = 0.093) and LV ejection fractions (p = 0.981). Also, the left atrium (LA) dimension (p = 0.0002) and volume indexed (p < 0.0001) were higher in the judokas, as were the larger right ventricle (RV) areas. Finally, the judokas showed higher VO2max (p = 0.012), O2 pulse (p = 0.007), VE/O2 LT1 (p = 0.041) and VE/O2 LT2 (p = 0.036) values, with a lower resting heart rate (p = 0.031) and higher exercise capacity (p = 0.011).Conclusions:
The judokas showed substantial differences in cardiac morpho-functional adaptations from the weightlifters, and, accordingly, judo should be more properly considered not a pure strength sport but more similar to mixed disciplines of the ESC classification.
