Validity of dynamical analysis to characterize heart rate and oxygen consumption during effort tests

This study evaluates dynamical analysis of heart rate and oxygen consumption during effort tests to characterize physical performance, finding that gain metrics are robust and informative.

Enhanced fitness relates to reduced cerebrovascular reactivity and perfusion in a sample of very healthy older adults

The paper examines the relationship between fitness, cerebral blood flow, and cerebrovascular reactivity in older adults, finding that higher fitness is associated with reduced cerebrovascular reactivity and altered hemodynamic responses.
