Key result
A 20-week soccer season is linked to resting ventricular volume changes in adolescent females.
Why the study?

Does a 20-week soccer season change ventricular morphology and function in female adolescent athletes?
In female adolescent soccer players, a 20-week season induces changes in resting ventricular volume but not wall thickness or systolic function.
Seasonal ventricular volume shifts in female adolescent soccer players should not alter training; leaves open sex-specific remodeling effects.
PURPOSE: To evaluate the influence of physical maturity on the changes in ventricular morphology and function with sport training in female youth athletes. METHODS: Thirty-two female athletes (age 13-18 years) underwent height and weight measurement and 2-D echocardiographic evaluation immediately prior to, and following, a 20-week soccer season. Pre- and post-season left ventricular end-diastolic diameter (LVEDD), end-diastolic volume (LVEDV), ejection fraction (LVEF), stroke volume (LVSV), mass (LVM), and posterior wall thickness (LVPWT), right ventricular end-diastolic diameter (RVEDD), end-diastolic area (RVEDA), and fractional area change (RVFAC), and interventricular septal thickness (IVST) were compared. In-season change in each variable was compared across pre-season hours of vigorous physical activity (0-1, 2-3, >3 hours). In-season changes in echocardiographic variables did not differ across hours of pre-season vigorous physical activity (p > 0.05 for all). CONCLUSION: Among female adolescent soccer players, in-season training elicits changes in resting ventricular volume, but not wall thickness or systolic function. These adaptations do not appear to be influenced by pre-season physical activity level.

Watson et al. (2018) conducted an observational in Adolescent female athletes (n=32). Sport training (20-week soccer season) vs. Pre-season baseline was evaluated on Changes in ventricular morphology and function (p=0.040). A 20-week soccer season in adolescent female athletes elicited changes in resting ventricular volume (p=0.040), but not wall thickness or systolic function, regardless of pre-season activity level.
