Multi-site lactate kinetics during moderate intensity resistance and endurance exercise in definitive and probable arrhythmogenic cardiomyopathy

Key Result

Moderate intensity resistance and aerobic exercise in arrhythmogenic cardiomyopathy yield differing lactate concentrations across the radial artery, pulmonary artery, and femoral vein.

Key Points

To examine how lactate concentration varies across different vascular sites during moderate intensity resistance and endurance exercises.
Compared lactate levels at rest and during moderate intensity resistance and endurance exercise.
Conducted exercises such as handgrip, bicep curls, and cycling for specified durations.
Measured lactate concentrations in the radial artery, pulmonary artery, and femoral vein.
Lactate concentrations differed significantly across various vascular sites.
Moderate intensity aerobic cycling showed higher lactate levels compared to resistance exercises.
Lactate responses varied between the radial artery, pulmonary artery, and femoral vein.

Abstract

Distribution of lactate concentration across vascular sites and exercise. Comparison of rest and moderate intensity resistance and aerobic exercise: Lactate concentration differs across vascular sites. Handgrip (HG), bicep curl (BC), 20 (20min) and 40 (40min) of aerobic cycling. A: Radial artery (RA). B: Pulmonary artery (PA). C: Femoral vein (FV).
