Enhanced left ventricular performance in endurance trained older men.
Why the study?
Does strenuous endurance exercise training improve left ventricular systolic performance and stroke volume at peak exercise in older men?
Population
18 older men, comprising 9 male master athletes and 9 older sedentary healthy men.
Comparison
Strenuous endurance exercise training of long… vs Sedentary lifestyle.
Design
Cross-sectional

Implication
Associated with enhanced peak hemodynamics in older athletes; hypothesis-generating and requires prospective confirmation before practice implications.
Structured PICO
Does strenuous endurance exercise training improve left ventricular systolic performance and stroke volume at peak exercise in older men?
P
Population
18 older men, comprising 9 male master athletes (mean age 64 +/- 2 years) and 9 older sedentary healthy men (mean age 63 +/- 1 year).
I
Intervention
Strenuous endurance exercise training of long duration (highly trained master athletes).
C
Comparator
Sedentary lifestyle (older sedentary healthy controls).
O
Outcome
Left ventricular systolic function and cardiovascular adaptations (stroke volume, cardiac output) at rest and during exercise.surrogate
Strenuous endurance training in older men induces volume-overload left ventricular hypertrophy and enhances systolic performance at peak exercise, contributing to increased stroke volume.
