, Walter O Frey,


The data reports the physiological characteristics of healthy subjects, aerobic fitness and the insertion/deletion polymorphism of the angiotensin converting enzyme gene, as well as the accrued muscle oxygen deficit and hemoglobin concentration and power output, during work-matched concentric and eccentric interval-type exercise on a soft-robot. Data on the accrued muscle oxygen deficit and hemoglobin concentration as computed in test-retest experiments are included as well.


Steps to reproduce

-Recruitment of not-specifically trained healthy subjects -Cardiorespiratory measurements during cycle ergometry to exhaustion to characterize aerobic fitness -Interval-type pedaling exercise on a soft robotic device with a concentric and eccentric contraction protocol -Near-infrared spectroscopy to measure muscle oxygen saturation and hemoglobin non-invasively in vastus lateralis and gastrocnemius muscle -Typing of the ACE-I/D gene polymorphism (presence or absence of the ACE D-allele) from genomic material as extracted from fresh buccal swabs. -Computation of the area under the curve for the oxygen saturation versus baseline and the AUC of the AUC of hemoglobin concentration during exercise.
