Alternative Text Description of Graph 3: Time-Series Information of Five Characteristic Frequencies
Graph depicts time-series information of mean amplitudes of metabolic, neurogenic, myogenic, respiratory, and cardiac controls and mean skin blood flow of 10 older people. Each data point represents the mean of amplitudes of a one minute period of the characteristic frequency during baseline (1-10 min), local heating (11-60 min), and post-heating (61-70 min) periods. Metabolic control shows an earlier increase in the amplitude as compared with the increase in the first peak of the biphasic blood flow response to local heating.
