Key result
Young competitive male rowers showed enhanced left ventricular performance with a lower ejection duration percentage (31.9% vs 38.4%) and lower arterial stiffness compared to recreational athletes.
Why the study?
The study was conducted to investigate the influence of training status on cardiovascular function in young male recreational and competitive rowers.
Does competitive rowing training improve cardiac and vascular functioning compared to recreational sports in young healthy males?

Absolute Event Rate: 31.9% vs 38.4%
p-value: p=0.026
Young competitive male rowers exhibit enhanced left ventricular performance and lower arterial stiffness compared to recreationally trained individuals, indicating positive cardiovascular adaptations to high-intensity training.
Suggests enhanced LV performance in competitive rowers; hypothesis-generating and requires longitudinal studies to confirm causality.
Introduction The aim of the study was to investigate the influence of training status on cardiovascular function in young male recreational and competitive rowers. Methods Ejection duration in percentage to the heart rate period (ED%), subendocardial viability ratio (SEVR), augmentation index at 75 bpm (AIx75) and carotid to femoral pulse wave velocity (cf-PWV) of competitive rowers (CR) (age 17.6 ± 4.1 years), recreational rowers (RR) (age 16.7 ± 2.70 years) and athletes practicing other recreational sports (ORS) (age 15.3 ± 1.4 years) were assessed. Results ED% was lower in CR compared to ORS (31.9 ± 3.9% vs. 38.4 ± 4.8%; p = 0.026) and cf-PWV was higher in CR compared to ORS (5.5 ± 1.0 m/s vs. 4.7 ± 0.5 m/s; p = 0.032). SEVR was higher in CR compared to RR and ORS (165.8 ± 33.7% vs. 127.4 ± 30.4% and 128.3 ± 27.8%; p = 0.022) and AIx75 was lower in CR compared to RR and ORS (−15.7 ± 8.6% vs. 1.2 ± 9.9% and 1.5 ± 9.1; p = 0.001). Discussion Healthy, young competitive male rowers reported higher myocardial performance and better cardiovascular health than recreational athletes. Interpretations of cf-PWV in competitive rowers should be performed alongside other cardiovascular indicators.

Falcioni et al. (2023) conducted a cross-sectional in Healthy young male athletes (n=28). Competitive rowing vs. Recreational rowing or other recreational sports was evaluated on Ejection duration in percentage to the heart rate period (ED%) (p=0.026). Young competitive male rowers showed enhanced left ventricular performance with a lower ejection duration percentage (31.9% vs 38.4%) and lower arterial stiffness compared to recreational athletes.
