Strain rate and tissue tracking imaging in quantitation of left ventricular systolic function in endurance and strength athletes
Why the study?
Does long-term physical training affect left ventricular longitudinal contraction in elite athletes compared to normal subjects?
Population
44 males, comprising 17 elite endurance athletes, 15 elite strength athletes, and 12 control subjects of…

Implication
Increased LV longitudinal function in strength athletes may reflect training adaptation; cross-sectional data leaves open causality and clinical relevance.
Structured PICO
Does long-term physical training affect left ventricular longitudinal contraction in elite athletes compared to normal subjects?
P
Population
44 males, comprising 17 elite endurance athletes, 15 elite strength athletes, and 12 control subjects of similar age.
I
Intervention
Long-term physical training (endurance or strength)
C
Comparator
No elite physical training (normal control subjects)
O
Outcome
Left ventricular longitudinal contraction assessed by strain rate analysis and tissue tracking imagingsurrogate
Elite strength athletes demonstrate increased longitudinal left ventricular systolic function despite significant left ventricular hypertrophy, while endurance athletes maintain normal function.
