Key result
Maximal working capacity > 230 Watt was associated with significantly higher myocardial PCr/b-ATP ratios compared to capacity < 200 Watt (1.93 vs 1.59; p<0.001).
Why the study?
Is physical capacity associated with myocardial high-energy phosphate metabolism in healthy men?
Cross-Sectional (n=105)
Is physical capacity associated with myocardial high-energy phosphate metabolism in healthy men?
Absolute Event Rate: 1.93% vs 1.59%
p-value: p=<0.001
Higher physical fitness is associated with improved myocardial high-energy phosphate metabolism in healthy men.
No takes yet. Share an insight, caveat, or question.
Higher fitness may link to better myocardial energetics; hypothesis-generating and should not yet change practice.
Klug et al. (2007) conducted a cross-sectional in Healthy (n=105). Maximal working capacity > 230 Watt vs. Maximal working capacity < 200 Watt was evaluated on Phosphocreatinine to beta-ATP ratio (PCr/b-ATP) (p=<0.001). Maximal working capacity > 230 Watt was associated with significantly higher myocardial PCr/b-ATP ratios compared to capacity < 200 Watt (1.93 vs 1.59; p<0.001).
